RADIO FREQUENCY HEALTH LIMITS FOR ENCOMPASS 4 READER USING AN EXTERNAL
ANTENNA IN FREQUENCY BAND OF 902.25 TO 903.75 AND 910.00 TO 921.50 MHZ
Several agencies (OSHA, FCC, IC) have environmental guidelines regulating maximum
permissible exposure (MPE) or “safe” exposure levels that this product falls under. To ensure
that proper safety guideline for the end users of this product, i.e. Occupational (Controlled) and
General Population/ Public (Uncontrolled), the recommended levels for each of the agencies are
presented in the next sections with TransCore’s recommendations for safety in the last section.
OSHA (Occupational Safety and Health Administration)
OSHA (an agency of The United States of America) legislates in the Code of Federal
Regulations (CFR) Title 29 Part 1910 Subpart G 1910.97 titled “Nonionizing radiation”, a
maximum safe exposure limit of 10 milliwatts per square centimeter (mW/cm2) during any 0.1hour period (i.e. 6 minutes). Using the frequency (in the middle of the band of operation of this
equipment) of 915 MHz and the highest antenna gain that this equipment is certified for use in a
final installation, the minimum safe distance was calculated to be 8in (20cm).
FCC (Federal Communication Commission)
FCC (an agency of The United States of America) legislates in the Code of Federal Regulations
(CFR) Title 47 Chapter I Subchapter A Part 1 Subpart I Section 1.1310 titled “Radiofrequency
radiation exposure limits” that the maximum permissible exposure (MPE) is the following:
Occupational/Controlled Exposure
Power density = frequency(in MHz)/300 mW/cm2 with an Averaging time of 6 Min
General Population/Uncontrolled Exposure
Power density = frequency(in MHz)/1500 mW/cm2 with an Averaging time of 30 Min
Using the frequency (in the middle of the band of operation of this equipment) of 915MHz and
the highest antenna gain that this equipment is certified for use in a final installation, the
minimum safe distance was calculated. The MPE minimum distances are 14in (36cm) for the
Occupational/Controlled environment, and 31.5in (80.5cm) for the General Population/
Uncontrolled environment.
Industry Canada (Innovation, Science and Economic Development Canada)
Industry Canada (a Department of the Government of Canada) sets out the requirements in Radio Standards
Specification RSS-102, Issue 5 guidelines, recommending a maximum safe power density in W/m2. Thus, the
vi
Encompass 4 Reader System Guide
maximum permissible exposure for general population/ uncontrolled exposure at 915MHz is 2.77 W/m2. The
average time is 6 minutes. The maximum permissible exposure (MPE) is the following:
Controlled Environment
Power density = 0.6455*frequency(in MHz)0.5 W/m2 with a Reference Period time of 6 Min
General Public/Uncontrolled Environment
Power density = 0.02619*frequency(in MHz)0.6834 W/m2 with a Reference Period time of 6 Min
Using the frequency (in the middle of the band of operation of this equipment) of 915MHz and
the highest antenna gain that this equipment is certified for use in a final installation, the
minimum safe distance was calculated. The MPE minimum distances are 18in (45cm) for the
Controlled environment and 47in (120cm) for the General Public/Uncontrolled environment.

LIMITES D’EXPOSITION AUX RADIOFRÉQUENCES POUR LE LECTEUR ENCOMPASS 4
UTILISANT UNE ANTENNE EXTERNE SUR LA BANDE DE FRÉQUENCES DE 902.25 À 903.75
ET DE 910.00 À 921.50 MHZ
Plusieurs organismes (OSHA, FCC, IC) publient des directives environnementales qui
recommandent des limites d’exposition maximale autorisée (normes MPE) ou des niveaux
d’exposition « sûrs » auxquels cet appareil se conforme. Pour faire en sorte que chaque
utilisateur final ait connaissance des directives de sécurité qui le concerne, que ce soit dans son
travail (accès contrôlé) ou pour la population générale/le grand public (accès non contrôlé),
TransCore présente les niveaux recommandés par chaque organisme dans ses recommandations
sécuritaires détaillées dans la dernière section.
OSHA (Occupational Safety and Health Administration)
Dans le Code des réglementations fédérales (CFR), Titre 29, Partie 1910, Sous-partie G
1910.97, intitulée « Nonionizing radiation » (Rayonnements non ionisants), l’OSHA
(organisme américain) recommande un plafond d’exposition maximale de 10 milliwatts par
centimètre carré (mW/cm2) pendant une période de 0,1 heure (soit 6 minutes). En utilisant la
fréquence de 915 MHz (milieu de la bande de fréquences de cet appareil) et le gain d’antenne
maximal pour lequel cet appareil a reçu une certification d’utilisation dans une installation
finale, la distance minimale sécuritaire est de 20 cm (8 po).
FCC (Federal Communication Commission)
Dans le Code des réglementations fédérales (CFR), Titre 47, Chapitre I, Sous-chapitre A, Partie
1, Sous-partie I, Section 1.1310 intitulée « Radiofrequency radiation exposure limits » (Limites
d’exposition aux rayonnements de radiofréquence), la FCC (organisme américain) établit les
limites d’exposition maximale autorisée (normes MPE) comme suit :
Exposition professionnelle/contrôlée
Densité de puissance = fréquence (en MHz)/300 mW/cm2 avec une durée moyenne de 6 min.
Exposition de la population générale/non contrôlée
Densité de puissance = fréquence (en MHz)/1500 mW/cm2 avec une durée moyenne de 30 min.
En utilisant la fréquence de 915 MHz (milieu de la bande de fréquences de cet appareil) et le gain d’antenne
maximal pour lequel cet appareil a reçu une certification d’utilisation dans une installation finale, la distance
minimale sécuritaire est la suivante : les distances MPE minimales sont de 36 cm (14 po) pour
l’environnement professionnel/contrôlé et de 80,5 cm (31,5 po) pour la population générale/environnement
non contrôlé.
ix
Encompass 4 Reader System Guide
Industrie Canada (Innovation, Sciences et Développement économique Canada)
Le Cahier des charges sur les normes radioélectriques 102, 5e édition, d’Industrie Canada (un
ministère du Gouvernement du Canada) établit des recommandations pour une densité de
puissance maximale sécuritaire en W/m2. Ainsi, l’exposition maximale admissible pour la
population générale/non contrôlée à 915 MHz est calculée à 2,77 W/m2. La durée moyenne est
de 6 minutes. Les limites d’exposition maximale autorisée (normes MPE) sont les suivantes :
Environnement contrôlé
Densité de puissance = 0,6455*fréquence (en MHz)0,5 W/m2 avec une durée de référence de 6
min.
Grand public/environnement non contrôlé
Densité de puissance = 0,02619*fréquence (en MHz)0,6834 W/m2 avec une durée de référence de 6
min.
En utilisant la fréquence de 915 MHz (milieu de la bande de fréquences de cet appareil) et le
gain d’antenne maximal pour lequel cet appareil a reçu une certification d’utilisation dans une
installation finale, la distance minimale sécuritaire est la suivante : les distances MPE minimales
sont de 45 cm (18 po) pour l’environnement professionnel/contrôlé et de 120 cm (47 po) pour le
grand public/environnement non contrôlé.

manual or operator guide exists. Once the system is set up and tested by the
authorized installer, Encompass 4 Reader System operation requires no end-user
intervention.
System Guide Organization
Note: TransCore offers the Encompass 4 Reader in two models: one with an integrated antenna and one that requires connection to an external antenna. In this system
guide, information and instructions for both Encompass 4 Reader models are presented. Where separate instructions dictate, a section detailing one Encompass 4
Reader model is followed immediately with a section detailing the other reader model.
In this system guide, the reader with an integrated antenna is listed first. In cases

System Description
The Encompass 4 Reader System is a dual-protocol reader supporting the low-cost,
high-performance SeGo radio frequency identification (RFID) technology. SeGo technology provides the capability to read miniature RFID tags in a myriad of options
including rugged, durable, or thin flexible forms such as the eGo Plus Sticker Tag. The
Encompass 4 Reader System also supports legacy transportation applications such as
1-5
Encompass 4 Reader System Guide
gated toll, parking, or security gate access and is designed to be compatible with existing TransCore SmartPass® parking access control applications certified for licensed
use. The Encompass 4 Reader System also supports the TransCore eGo and TransCore
ATA/ISO tag types, as well as the IAG tag protocol.
The Encompass 4 Reader System is a high-power unit that can read both half-frame
and full-frame tags. The reader output power can be adjusted using reader commands.
Reader
The Encompass 4 Reader System consists of an input/output (I/O) module, a power
supply, a reader logic board (also called a tag decoder), a radio frequency (RF) transmitter/receiver (called the RF module), and a patch antenna.
A second version of the Encompass 4 Reader is designed to be used with a high-performance external antenna. These Encompass 4 Reader System components are contained in a highly reliable, compact, and easy-to-install environmentally-sealed
package. Figure 1-1 shows the front and side views of an Encompass 4 Reader System.
Figure 1-1 Encompass 4 Reader System Front and Side Views
Tags
The Encompass 4 Reader System has the capability to read TransCore SeGo protocol
tags, the Intellitag-based eGo protocol tags, TransCore ATA protocol, and TransCore
ISO-compliant read-only full- and half-frame tags, as well as IAG protocol tags.
How It Works
The Encompass 4 Reader System directs the RF module to generate an RF signal,
which is broadcast through the integrated or external antenna. Entering the Encompass
4 Reader System’s reading range, a TransCore RFID tag installed on a vehicle or other
1-6
Introduction
object to be tracked adds its programmed identification information to the signal and
reflects the signal back to the Encompass 4 Reader System. The Encompass 4 Reader
System receives this modified, or modulated signal, and decodes the tag data carried
by the reflected signal and transmits this data to a local host computer for processing.
Licensing Requirements
An FCC license provides the user with the legal authorization to operate the Encompass 4 on the licensed frequencies at the site specified in the license. Only an authorized installer or service technician can set the RF frequency of the Encompass 4
Reader System to the frequency specified in the FCC site license.
The FCC license may provide the user with protection and authorization to maintain
the system should any other RFID product be used in the licensed area after the
Encompass 4 equipment is installed.
Users of the Encompass 4 Reader System in the United States must obtain a license
from the FCC. In the United States, the authorized modulated frequency band for this
product is 911.75 to 919.75 MHz and the authorized continuous wave frequency band
is 902.25 to 903.75 MHz and 910.00 to 921.50 MHz.
The user is responsible for filing the FCC license according to FCC regulations, but
the TransCore dealer will provide assistance and support as necessary to complete
these forms. Forms are available online at the FCC internet site www.fcc.gov/Forms/
Form601/601.html or you can file online at wireless.fcc.gov/index.htm?job=online_filing. For further information on obtaining the license contact TransCore.

Chapter 2
Developing the Site Plan
This chapter discusses site plan development for installing the
Encompass® 4 Reader System.
Overview
Note: In this section, unless specifically stated, E
" ncompass 4 Reader"applies
both to the Encompass 4 Reader with integrated antenna and Encompass 4
Reader with external antenna.
Developing a site plan provides the foundation for the site’s system design and establishes the following system configuration parameters:
•
Number and general location of primary components
•
Number of different radio frequencies required
Gathering relevant site information is crucial before applying for Federal Communications Commission (FCC) approval and ordering and installing Encompass 4
Reader(s) and tags.
Also, consider the following factors when developing a site plan:
•
Type of tags used in the facility
•
Reader and/or antenna and tag alignment
•
Site layout and traffic flow
•
Encompass 4 Reader and/or antenna mounting requirements
•
Encompass 4 Reader electrical requirements
•
Encompass 4 Reader communications requirements
These factors provide relevant information regarding each site’s physical and electromagnetic environment and the conditions under which the system must perform.
Reading of Mixed Population Tags
The Encompass 4 Reader reads TransCore’s Super eGo® (SeGo) protocol tags, the
American Trucking Association (ATA) and International Organization for Standardization (ISO) read-only tags, whether powered by battery or beam, application-specific integrated circuit (ASIC)-based tags with Intellitag technology, or Inter-Agency
2-3
Encompass 4 Reader System Guide
Group (IAG) tags. The reader can read the ATA or ISO read-only tags in the presence
of Intellitag-based tags; however, attempting to read an Intellitag-based tag in the
presence of an ATA or ISO read-only tag is not recommended.
Caution
Attempting to read an Intellitag-based tag in the presence of an ATA or ISO read-only
tag may provide unreliable results.
The factors that influence the readability include, but are not limited to physical orientation and configuration, type of read-only tag, ratio of backscatter cross-section of the
tags, and whether the tag is battery- or beam-powered.
Reader and Tag Alignment
The position of the Encompass 4 Reader and placement of the tag on the vehicle must
be compatible. Also, consider any existing tagged vehicles now using the facility to
determine the optimal Encompass 4 Reader location and orientation at the site.
Note: If any of the vehicles using your facility already have tags, such as those used
in toll applications, contact TransCore for information about mixed-tag installations
before you plan tag type, location, and programming.
Three primary criteria must be satisfied to achieve the highest read reliability:
•
Polarization of the tag and the Encompass 4 Reader must be aligned in the same
direction — both horizontal.
•
The installed tag must be in a direct, unobstructed line of sight to the Encompass 4
Reader.
•
Tags designed to be mounted in a vehicle windshield must be mounted in the vehicle’s windshield, and tags designed to be mounted on the exterior surface of the
vehicle must be mounted on the exterior surface of the vehicle.
Caution
A tag may not be reliably read unless the preceding criteria are met.
2-4
Developing the Site Plan
Polarization
The polarization of the tag must be aligned in the same direction as the Encompass
4 Reader, as shown in Figure 2-1.
Note: Matching the tag and antenna polarization is critical to obtain optimal system
performance.
Figure 2-1 Tag and Reader Orientation

Encompass 4 Reader System Guide
Unobstructed Line of Sight
For optimum readability, install the Encompass 4 Reader and the vehicle’s tag so that
when the vehicle approaches the Encompass 4 Reader, the tag is directly facing the
reader and the line of sight is clear between the Encompass 4 Reader and the tag. If a
fence or barrier is between the tag and the reader, the Encompass 4 Reader cannot reliably read the tags. Figure 2-2 illustrates possible installation locations of an Encompass 4 Reader in relation to a tag’s mounting location on a vehicle. If the tags are not
in the recommended location, reliable optimum operation requires lower vehicle
speeds.
Figure 2-2 Encompass 4 Reader Location Relative to Tag Position
2-6
Developing the Site Plan
If the Encompass 4 Reader is installed on a pole or wall to the left of the vehicle, optimal tag position is on the left side of the vehicle as illustrated in Figure 2-3.
Figure 2-3 Typical Tag Positions for U.S. Driver’s Side Reader
If an Encompass 4 Reader is installed on a pole or wall to the right of the vehicle, optimal tag position is on the right side of the vehicle as illustrated in Figure 2-4.
Figure 2-4 Typical Tag Positions for U.S. Passenger’s Side Reader
2-7
Encompass 4 Reader System Guide
If the Encompass 4 Reader is installed in an overhead location, optimal tag position is
in the top center of the windshield in the area behind the rear view mirror or on the
vehicle’s front license plate or center bumper as illustrated in Figure 2-5.
Figure 2-5 Typical Tag Positions Used with Overhead Reader
Note: Metallized coatings on some vehicle windshields and windows shield the RF
energy emitted by the Encompass 4 Reader and may cause tags to be misread. Many
metallized windshields have areas that are not metallized in which the tag can be
placed and reasonable results achieved. If there are no openings in the metallized
coating in which to install an interior tag, install exterior-type tags on the exterior of
the vehicle.
Refer to Chapter Chapter 3, ”Choosing, Installing, and Removing Tags” for more
detailed information on tag positioning.

•
Low antenna profile
Antenna and Tag Alignment
The position of the antenna connected to the Encompass 4 Reader and placement of
the tag on the vehicle must be compatible. Also, consider any existing tagged vehicles
now using the facility to determine the optimal Encompass 4 Reader antenna location
and orientation at the site.
Note: If any of the vehicles using your facility already have tags, such as those used
in toll applications, contact TransCore for information about mixed-tag installations
before you plan tag type, location, and programming.
Three primary criteria must be satisfied to achieve the highest read reliability:
•
Polarization of the tag and the Encompass 4 Reader antenna must be aligned horizontally.
•
The installed tag must be in a direct, unobstructed line of sight to the Encompass 4
Reader antenna.
•

performance.
2-11
Encompass 4 Reader System Guide
Unobstructed Line of Sight
For optimum readability, install the Encompass 4 Reader antenna and the vehicle’s tag
so that when the vehicle approaches the antenna, the tag is directly facing the antenna
and the line of sight is clear between the antenna and the tag. If a fence or barrier is
between the tag and the antenna, the antenna cannot reliably read the tags. Figure 2-2
illustrates possible installation locations of an Encompass 4 Reader antenna in relation
to a tag’s mounting location on a vehicle. If the tags are not in the recommended location, reliable optimum operation requires lower vehicle speeds.
Site Layout and Traffic Flow
The following site layout and traffic flow considerations are critical when determining
Encompass 4 Reader installation locations:
•
The Encompass 4 Reader read zone
•
Other Encompass 4 Reader units and antennas in the area
•
Lane configurations
•
Reflection, refraction, and diffraction of RF signals
•
Existing signal interference at the site
The Encompass 4 Reader Read Zone
The Encompass 4 Reader must be able to read the tag data properly within a specified
area, called the read zone, without reading other nearby tags or interfering with other
Encompass 4 Readers at the site. The following are some of the factors that affect the
size and shape of the read zone:
2-12
•
Mounting method used (pole or wall mount)
•
Mounting location (overhead or side mount)
•
Height from the ground and mounting angle
•
Mounting method used (pole or wall mount) of the antenna
•
Mounting location (overhead or side mount) of the antenna
•
Height from the ground and mounting angle of the antenna
•
Indoor or outdoor location
•
RF output attenuation
•
Range discrimination setting
Developing the Site Plan
•
Other sources of interference and reflection
The Encompass 4 Reader must be positioned to allow the RF signal to travel to and
return from the tags within the designated range and be placed in an area where it is
not likely to be bumped out of alignment. If the antenna becomes misaligned or some
nearby structure is added or removed, system operation can be seriously affected.
The external antenna must be positioned to allow the RF signal to travel to and return
from the tags within the designated range and be placed in an area where it is not
likely to be bumped out of alignment. If the antenna becomes misaligned or some
nearby structure is added or removed, system operation can be seriously affected.
For instructions on setting the read zone, see “Fine-Tuning and Verifying the Read
Zone” on page 8-19.
Other Encompass 4 Readers in the Area
Sites with more than one Encompass 4 Reader in proximity should have them configured with a frequency separation of at least 2 MHz from adjacent readers. If more than
one Encompass 4 Reader and antenna is in a side-by-side or multiple lane application,
the frequencies should be staggered. Also, Encompass 4 Readers may not operate
accurately if they directly face each other or are positioned back-to-back.
Table 2-1 shows examples of staggered reader frequencies in a site with up to 14 readers.

Lane Configurations
TransCore recommends that traffic be guided through a controlled lane to consistently
obtain accurate tag readings and to prevent physical damage to the Encompass 4
Reader. The following subsections describe some common lane configurations and
offer suggestions for positioning the Encompass 4 Reader within the controlled traffic
flow.
2-13
Encompass 4 Reader System Guide
Gate with Center Island Configuration
Figure 2-6 illustrates a typical gate application with the Encompass 4 Reader units
positioned on a center island to read tags mounted on the inside windshield on the
driver’s side (United States). The readers are placed to allow time for the gate to open
so the vehicle can roll through without stopping while not allowing room for an
untagged vehicle to be between the vehicle being read and the gate.

Developing the Site Plan
Parking Garage with Ticket Island Configuration
Figure 2-7 illustrates a parking garage application with each Encompass 4 Reader
mounted on the ticket island to read tags mounted on the inside center windshield or
on the center front vehicle bumper. The Encompass 4 Reader placement may require
the vehicle to stop before the gate opens.
Figure 2-7 Parking Garage Application
Overhead Reader Installation Configuration
Another option for Encompass 4 Reader placement is to mount it overhead in each
lane as illustrated in Figure 2-8. This illustration assumes that tags are mounted on the
inside center windshield or center bumper of the vehicle.

Lane Configurations for Encompass 4 Readers
Using an External Antenna
TransCore recommends that traffic be guided through a controlled lane to consistently
obtain accurate tag readings and to prevent physical damage to the Encompass 4
Reader and antenna.
Reflection, Refraction, and Diffraction of RF
Signals
RF signals can be reflected, refracted, or diffracted by metal objects, walls, and even
wet pavement or ice. Any of these factors can alter or degrade system performance.
When designing your site plan, you must consider permanent structures and transient
factors in the vicinity that may affect RF signals being generated by the Encompass 4
Reader. Permanent structures include buildings, chain link fences, guard shacks, and
gates. Transient factors include passing traffic and local weather conditions, such as
rain or snow. Symptoms of reflection, refraction, and diffraction include reading tags
that are out of the desired read zone or tags being read from another lane.
The most common RF reflectors are metallic surfaces. RF signals may also be partially reflected by nonconducting materials such as dirt, wood, ice, asphalt, and concrete. When nonconducting materials in the system environment become wet, they
increase reflection of RF signals.
The Encompass 4 Reader and/or antenna mounting location, aiming, and range control adjustment, and use of presence detectors can reduce interference from RF reflections. When these actions cannot adequately control reflections, other techniques such
2-16
Developing the Site Plan
as shielding, absorbing, range sensitivity adjustment, or barriers can also be used. See
Chapter 9, ”Troubleshooting and Maintenance” for more information.
Existing Interference
Interference from RF and electrical sources can degrade system performance and must
also be considered in the site design. Fluorescent lights, neon signs, nearby radio stations, or power lines can interfere with the optimal operation of the system. The magnetic impulse noise from relays that control gate opening and closing can also disrupt
the RF signal.
Interference may degrade both reader and tag performance. Existing interference at
the site may be shielded, removed, or positioned further from the Encompass 4 Reader
and/or antenna. In some cases, changing the operating frequency of the Encompass 4
Reader may provide a simple solution. Readers in proximity should have at least a 2
MHz frequency separation. See “Other Encompass 4 Readers in the Area” on page 213. Strong RF sources of any frequency, in proximity to the tag, can preclude the tag
receiving the reader interrogation (see Chapter 9, ”Troubleshooting and Maintenance” ).
Electrical and Communications Requirements
All construction work at the site must be completed before installing the Encompass 4
Reader. Electrical and communications cables should be installed according to all
applicable local and federal building code requirements. Specific instructions for positioning and installing the Encompass 4 Reader are discussed in Chapter 4, ”Installing
the Encompass 4 Reader”
Junction Box
Use a watertight junction box that meets applicable local and national building codes
for connecting power and communications wiring. The junction box houses the terminal strip for power and communications connections. TransCore recommends a
NEMA Type-4 junction box with a back mounting panel.
Power and Communications Cables
Cable length for power and communications depends on the physical characteristics
of the Encompass 4 Reader installation site. Table 2-2 lists accessory kits available for
cabling options based on your site’s requirements.

Electrical Power
A dedicated electrical power supply must be present at the site and available to the
Encompass 4 Reader at all times. The power must be 16-20V AC or 16-28V DC. A
step-down transformer is available (North America only) to convert a 120V AC
duplex wall outlet with ground to 18V AC, as is a step-up transformer to convert a
low-voltage 12V AC outlet to 18V AC. Consult your local and national electrical
codes for installation and safety requirements.
Note: Encompass 4 Readers installed outside North America require a locally supplied transformer.
If 18V AC or 18V DC power is available, the transformer option is unnecessary.
TransCore offers a Class C transformer accessory kit (part number 76-1620-005) for
sites where 110V AC is available. It is the installer’s responsibility to supply conversion equipment and wiring for other voltages. Table 2-3 contains power supply current
requirements.

Host Communications
Your site design must include communications between the Encompass 4 Reader and
a host computer. The Encompass 4 Reader communicates with the host computer
through an asynchronous serial line or through a Wiegand interface. This serial line
can be an RS–232 interface or an RS–422 interface. The host computer must be able
to accept one of the interfaces shown in Table 2-5.

Developing the Site Plan
RS–232 Interface
Use an RS–232 interface if one or more of the following conditions apply to your site:
•
The host computer system is 50 ft (15.2 m) or less from the Encompass 4 Reader.
•
The host computer system is more than 50 ft (15.2 m) from the Encompass 4
Reader and a pair of RF modems or limited distance modem/line drivers over
copper wire are used for communications between the Encompass 4 Reader and
the host. The distance from the RF modem to the Encompass 4 Reader should not
exceed 50 ft (15.2 m).
•
Other common communications devices that can extend the RS–232 distance,
such as fiber optic modems, have been selected.
The standard RS–232 connection maximum distance depends on the baud rate, cable
type, and the RS–232 device at the other end.
Note: When extending the RS-232 interface, use a three-pair cable such as Belden
2919. Use a twisted pair for the black (RxD) with ground (black of the black/yellow
pair), and a twisted pair for red (TxD) with ground (black of the black/yellow pair).
The third pair of the three-pair cable can be used for a spare in the event either of the
other two pair are damaged or fail. The cable shield should be tied to a single-point
earth ground on the controller end of the cable.
RS–422 Interface
Use an RS–422 interface if one or more of the following conditions apply to your site:
•
The host computer is more than 50 ft (15.2 m) from the Encompass 4 Reader.
•
The host computer has an external limited-distance modem.
The standard RS–422 connection maximum distance depends on the baud rate, cable
type, and the RS–422 device at the other end.
Wiegand Interface
The Encompass 4 Reader can interface with equipment requiring the Wiegand
+5V DC data0-data1-ground interface. The reader uses the Wiegand interface
included with the RS–232 or RS–422 option.
Note: The Encompass 4 Reader comes from the factory with either RS–232 and Wiegand or RS–422 and Wiegand. If you want to use Wiegand, you must first connect the
Encompass 4 Reader using the RS–232 or RS–422 interface, set all necessary operating parameters in the reader, then set the Encompass 4 Reader’s configuration to Wiegand, and then connect the Encompass 4 Reader to the Wiegand interface.
Note: You must order tags programmed with Wiegand-formatted data when using a
Wiegand-compatible reader.
Note: When extending the Wiegand interface, use a three-pair cable such as Belden
2-21
Encompass 4 Reader System Guide
2919. Use a twisted pair for the red (Data1) with ground (yellow of the black/yellow
pair), and a twisted pair for blue (Data0) with ground (yellow of the black/yellow
pair). The third pair of the three-pair cable can be used for a spare in the event either
of the other two pair are damaged or fail. The cable shield should be tied to a singlepoint earth ground on the controller end of the cable.
Input/Output Circuits
To connect the Encompass 4 Reader to external equipment such as a treadle or traffic
control light, install wires from these devices at the junction box. The Encompass 4
Reader input circuit is designed to connect to a dry contact closure. The Encompass 4
Reader output circuits are single-pole, double-throw relays providing dry contact closures. These contacts are rated at 42.2V AC peak (30Vrms) or 60V DC, at 1 A maximum with noninductive load.
Output circuits are not intended for the direct control of electromechanical devices
such as motorized gates and barrier arms. For such applications, the Encompass 4
Reader output circuits should be used to drive a secondary, appropriately rated
high-power relay.
External Antenna Interface
For sites using an Encompass 4 Reader with external antenna, the design must include
an interface cable between the Encompass 4 Reader and the compatible antenna chosen for the site. The antenna interface is RF coaxial cable with male Type N sockets on
each end.
Table 2-6 is a summary of coaxial cable performance. Figures indicate maximum
lengths of cable in feet.

eGo Plus Sticker Tags are designed to be attached by a semi-permanent adhesive to
the interior surface of nonmetallic windshields 0.190 to 0.230 inches (4.82 to 5.84
mm) in thickness. For optimum performance, you must install the tag at least 2 inches
(5 cm) from the metal in the windshield frame and 0.75 inch (1.9 cm) from the rearview mirror support post. Detailed instructions for installing the eGo® Plus Sticker
Tag are found in the pocket guide “Quick and Easy Installation Instructions for the
eGo® Plus Sticker Tag.”
Some vehicles have a tinted area across the top of the windshield. If the tint is conductive, it can interfere with reading the tag. If a windshield has this conductive tint, the
tag must be installed at least 2 inches (5 cm) below this tinted area.
3-7
Encompass 4 Reader System Guide
Some vehicle windshields contain a metallic treatment that could prevent an interior
windshield-mounted tag from being read. However, many of these metallized windshields have areas that are not metallized. On a vehicle without open areas in its metallized windshield, you might need to install an Encompass 4 Reader-compatible LPT
on the vehicle. See the section “Installing eGo Plus License Plate Tags” on page 3-13.
Contact TransCore for more information. See the section “Technical Support” on page

Choosing, Installing, and Removing Tags
Installing eGo Plus License Plate Tags
Metallized coatings on some vehicle windshields and windows absorb the RF energy
emitted by the Encompass 4 Reader, thus causing tags to be misread. You must use
exterior LPTs on vehicles with metallized coatings on their windshields and windows.
Use license plate installation techniques to install tags on the exterior of vehicles that
have this type of window coating.
Note: The read zone of an overhead Encompass 4 Reader should be adjusted accordingly when an exterior tag is installed on a license plate, or the read zone will be
reduced.
Required Materials
•
Screwdriver (flat-blade or Phillips depending on the vehicle’s license plate
mounting screws)
•
Optional TransCore Exterior Tag Accessory Kit (19077-01). This kit contains
tamper-resistant mounting screws and wrench.
•
eGo Plus LPT
Positioning eGo Plus License Plate Tags
The eGo Plus LPT is installed over the license plate at the upper part of the vehicle’s
front license plate area.
Note: If your state does not require a front license plate, install the LPT in the area
where the license plate would normally be mounted. If your vehicle does not have a
front license plate area, contact your tag agency for other tag options.
The orientation of the tag is important. The tag must be mounted so that the holes on
the tag base plate are on the top edge.
eGo Plus LPT Installation Procedures
To mount the eGo Plus LPT
1. Remove the screws from the license plate area of your front bumper (Figure 313). If your vehicle does not have mounting screws you will need two selftapping threaded screws. You can also contact the tag agency to inquire about the
optional TransCore Exterior Tag Accessory Kit.

Ensure that the tag is correctly located before touching it to the glass. Once the
sticker tag is applied to the glass, it cannot be moved without damage to the tag.
5.
Holding the sticker tag by its edges, position the tag in the correct area of the
windshield (determined in Step 1), making sure the tag is oriented horizontally
and is at least two inches (5 cm) from the windshield frame and 0.75 inch (1.9
cm) from the mirror post.
6.
Press the sticker tag firmly against the glass and gently rub over the entire tag
surface. Ensure that no air bubbles remain between the sticker tag and the
windshield.
Removing eGo Windshield Sticker Tags
Removing eGo WSTs requires the use of a plastic scraper or equivalent tool. The tag
is inoperable once removed.
Installing eGo LPT
Follow the instructions presented in “eGo Plus License Plate Tag” on page 3-5 when
installing an eGo LPT.
Installing Interior ATA Tags
Interior ATA-protocol tags are installed using hook-and-loop material or double-sided
tape attached to the tag and to the windshield. When using hook-and-loop material,
the loop material should be applied to the back of the tag and the hook material should
be applied to the windshield. After the tag is installed, it can be removed easily and
used in any vehicle that has corresponding hook material affixed to the windshield.
Note: Installing interior tags using double-sided tape results in a semipermanent
attachment; the tag will be more difficult to remove than one installed using hook and
loop material.
Interior ATA-protocol tags may be ordered from the factory with hook-and-loop
material or double-sided tape already applied to the tag. The adhesive on this material
is specially formulated for temperature extremes inside vehicles.

5.
Press the tag firmly against the glass.
Removing Interior ATA Tags
To remove an interior ATA-protocol tag installed using hook-and-loop material,
simply pull the tag away from the windshield.
To remove an interior ATA-protocol tag installed using double-sided tape, slowly pry
off the tag with a thin tool, such as a putty knife.
Installing ATA License Plate Tags
Metallized coatings on some vehicle windshields and windows absorb the RF energy
emitted by the Encompass 4 Reader, thus causing tags to be misread. Use exterior
LPTs on vehicles with metallized coatings on windshields and windows.
Use license plate installation techniques to install tags on the exterior of vehicles that
have this type of window coating.
Note: The read zone of an overhead Encompass 4 Reader should be adjusted accordingly when an exterior tag is installed on a license plate, or the read zone will be
reduced.
Exterior tags may be installed on metal or plastic bumpers using the existing license
plate bracket and hardware.
The tag can be mounted on the front bumper where the license plate is normally
located or mounted directly to the front license plate or license plate bracket. Once
installed, the face of the tag should be pointing directly forward or slightly upward. If
the bumper, license plate, or license plate bracket has any material that overhangs the
tag, the tag will not function properly.
Required Materials
You need the following supplies to install license-plate mounted tags:
•
Exterior LPT
•
Two 0.25-inch (.63 cm) bolts and nuts (user-supplied). Length of the bolts can
vary depending on vehicle model.
•
Screwdriver and wrench (user-supplied)
•
0.25-inch (.63 cm) spacers or washers (if needed). Thickness of spacers can vary
depending on vehicle model.

Encompass 4 Reader System Guide
Positioning ATA License Plate Tags
The orientation of the tag is important. The tag must be mounted so that the holes on
the tag base plate are on the bottom edge. See Figure 3-22.
Figure 3-22 Proper Tag Orientation
When positioning the tag, observe the following guidelines:
•
The tag should be horizontal and parallel to the ground.
•
The tag face should be perpendicular or tilted slightly upward.
•
•
The tag may lean to the rear a maximum of 30 degrees.
The tag may lean to the front a maximum of 10 degrees.
ATA License Plate Tag Installation Procedures
To mount the LPT
1. Position the tag so that the holes in the tag are on the bottom edge and the tag is
within 18 inches (.45 m) of the center of the front bumper as illustrated by the
shaded area in Figure 3-23.

•
Tags can be mounted to plastic bumpers using self-threading screws.
•
Metal bumpers should be pre-drilled; self-threading screws may be used.
Alternate Mounting Locations
If the exterior type tag cannot be mounted on the license plate bracket or directly on
the bumper, it may be mounted on a relatively vertical front surface of the vehicle. The
exterior tag should be mounted as close to the bumper as possible, following all guidelines regarding orientation, obstruction, and overhang given for bumper mounting. For
applications where the integrity of the mounting surface cannot be compromised, the
exterior tag can be mounted on a smooth flat surface using double-sided tape.
Required Materials
Exterior tags need to be installed on a relatively flat surface. You need the following
materials to install exterior tags:
•

4-22
Installing the Encompass 4 Reader
Mounting the Antenna
If you are using the Encompass 4 Reader that requires an external antenna in permanent installations, the antenna should be positioned as close as possible to the Encompass 4 Reader. Long cable runs increase system sensitivity to noise. See Table 2-6 on
page 2-22 for maximum RF cable lengths.
Before you connect the external antenna to the Encompass 4 Reader, you must perform the following voltage discharge procedure.
Discharging Voltage from the External Antenna
Use these instructions to discharge high voltage from the external antenna before proceeding with further pre-installation testing of the reader connected to an external
antenna.
Required Equipment
This procedure requires the following equipment.
•
TransCore Encompass 4 Reader (external antenna models only)
•
External antenna
•
RF cable
•
N-type load (e.g., 50 ) or RF attenuator (e.g., 20 dB)
Discharging the Voltage
4-23
Encompass 4 Reader System Guide
1.
Terminate the reader end of the RF cable with any N-type load or RF attenuator
(Figure 4-16).
Figure 4-16 Connect RF N-type Load or Attenuator to Reader Cable End

installer is using the electrical conduit for Earth Ground.
Installing the Encompass 4 Reader
4.
Remove the load or attenuator from the RF cable and connect cable to reader.
Once the antenna is discharged and properly connected to the reader, the reader
circuitry provides a DC path to keep any further charge from building up in the
antenna.
Caution
TransCore does not recommend using a screwdriver or other tool to short the
RF cable center conductor to the outer ground of the cable. This grounding
method can damage the center pin or the threads of the connector.
TransCore strongly advises that you use adequate Earth Ground for this voltage
discharge procedure in accordance with the National Electric Code for the
locale where you are installing the Encompass 4 Reader.
Mounting the Antenna Curb-Side
Some site designs, for example those with curb-side antennas, require that the antenna
be mounted on a round pole. The pole must be a minimum of 2 inches (5 cm) in diameter and should extend approximately 8 feet (2.4 m) above the pavement level. The
pole must be installed according to local building codes.
Note: Do not use an AA3152 Universal Toll Antenna for side-fire application.
Procedures
Use the following guidelines to mount an antenna on a curb-side round pole.
To mount the antenna to a curb-side pole
1. Follow the manufacturer’s directions to attach the antenna assembly to the pole
approximately 8 feet (2.4 m) above the pavement surface.

Warning
Do not cut the RS–232 red/black wires. If you cut the wires, you may not be able to
use them in the future for testing, setting frequency, or adding additional functions.
Connecting Sense Input and Sense Output Circuits
The Encompass 4 Reader has two sense input circuits and three sense output circuits
available. The sense input circuits can be used to notify the Encompass 4 Reader of
external events and are designed to be connected to a free-of-voltage dry contact.
Sense output circuits are single-pole, double-throw relays that provide normally
closed (NC) and normally open (NO) dry contacts. The relay contacts are rated at
42.2V AC peak (30 Vrms) or 60V DC at 1 A maximum. If controlling an external gate
or device requiring high current, an isolation transformer is required.
The following sections provide information to connect the sense input and sense output circuits.
Sense Input Circuits
The Encompass 4 Reader supports two sense inputs – sense input0 and sense input1–
which requires two sense input lines for each loop sense or a total of four sense input
connections. Sense input0 is the presence detection device line and is used to control
RF power. As shown in Figure 4-23, sense input0 is through the red/green wire pair on
the I/O pigtail. The Encompass 4 Reader expects the sense input0 circuit to close
when a vehicle is present (i.e., a NO condition). The minimum presence true period is
4-34
Installing the Encompass 4 Reader
fixed at 0 ms, which indicates that no delay occurs in closing the circuit when a vehicle is present.
Sense input1 allows the Encompass 4 Reader to monitor the status of a peripheral
device. The host computer can then check the status by polling the Encompass 4
Reader.
Figure 4-23 Sample Circuit Connections
For Encompass 4 Readers that are used with IAG protocols, the NC sense output0
common is connected to the NO sense output0 common via a jumper providing a
return for sense output0 NC. Figure 4-24 shows this wiring.
4-35
Encompass 4 Reader System Guide
Figure 4-24 Sample Circuit Connections for IAG Installations
Sense Output Circuits
The Encompass 4 Reader supports three sets of sense output signals. Two sets – sense
output0 and sense output1 – provide NO or NC sense outputs. The third sense output
set is dedicated for testing and set up of the reader. It is defined as the TAG_LOCK
signal, which indicates a valid tag is in the read field.
These sense outputs are dry contacts that provide NO and NC sense outputs. The relay
contacts are rated at 42.2V AC peak (30 Vrms) or 60V DC at 1 A maximum. If controlling an external gate or device requiring high current, an isolation transformer is
required.
As illustrated in Figure 4-23, sense output0, NC, is located on the orange/black pair.
Sense output0, NO, is located on the brown/black pair.
As shown in Figure 4-24, for IAG applications, Sense output0 NC, shares a common
return with sense output0 NO.
In Wiegand mode operation, the sense outputs are not controlled by a predefined output mode.
Table 4-9 lists the cable descriptions and functions for the interface signals. These
wire pairs can be used or terminated based on the specific project applications and site
requirements.

Installing the Encompass 4 Reader
Using Table 4-9 as a guide to the functions of each of the wire signals, connect the
remaining wires to the appropriate terminal blocks on the terminal strip in the junction
box.

Marking the Read Zone
The area where the Encompass 4 reads tags at the current RF range is called the read
4-38
Installing the Encompass 4 Reader
zone. The antenna pattern, or read zone, of the Encompass 4 Reader would look
roughly like a pear-shaped balloon if you were able to see it. When installing the
Encompass 4 Reader, you should first mark the unit’s read zone using the RF range set
at the factory-default maximum. You can later adjust the read zone using the techniques discussed in “Fine-Tuning and Verifying the Read Zone” on page 8-19.
If two Encompass 4 Readers are installed near each other, TransCore recommends that
you fine-tune each reader for the ideal read zone before connecting it permanently to
sense input/sense output and communications cables. A minimum of 2 MHz frequency separation between the two adjacent readers is required for correct operation.
Required Materials
You need the following materials to mark the read zone:
•
Test tags, supplied by the TransCore dealer or distributor
•
Piece of windshield-type glass 0.190 to 0.230 inches (4.82 to 5.84 mm) in thickness and approximately 12 inches (30.48 cm) square on which to attach the eGo
Plus Sticker Tag, eGo Plus Security Sticker Tag, or eGo WST
Caution
Both the eGo Plus Sticker Tag and eGo WST have a reduced read range when not
attached to glass.
• Audible circuit tester and 9V DC battery for circuit tester power as described in
the section “Bench Testing the Encompass 4 Reader Before Installation” on page
4-13.
•
Piece of chalk or roll of tape
•
Plastic or wooden yardstick for ATA or IAG tags
•
Vinyl electrical tape or hook-and-loop material
Procedures
Note: Using test tags that are not mounted to vehicles give a general idea of the read
pattern but the pattern will vary somewhat when actual vehicles with tags are tested.
Final adjustments must be made with tags properly mounted on a variety of vehicles.
To mark the read zone
1. Confirm the following:
•

Secure the ATA or IAG test tag to the end of the yardstick using electrical tape or
hook-and-loop material or affix the test eGo Plus or eGo WST to the glass. Be
sure the tag polarization (horizontal or vertical alignment) matches that of the
Encompass 4 Reader or antenna used. If using an eGo Plus-type test tag or eGo
WST, the glass should be in front of the tag (between the tag and the reader or
antenna).
8.
Stand directly in front of and about 5 feet (1.5 m) away (see Figure 4-25) from
the Encompass 4 Reader or antenna. Hold the stick or the piece of glass so that
the tag is positioned at a height and angle consistent with a tag installed on a
vehicle. The test tag should cause the audible tester to sound.
Note: If you hold the test tag in your hand, your hand absorbs the RF signal and
the test results are not accurate.
9.
Mark the spot with chalk or tape.
10. Move to the left until the sound stops and mark the ground with chalk or tape at
the location of the tag when the sound stopped.
11. Return to the center and then move to the right until the sound stops and mark the
ground with chalk or tape at the location of the tag when the sound stopped.
12. Return to the center and step backward 2 feet (0.6m) and repeat steps 5 through 7.

13. Continue moving the tag in this manner, placing marks on the ground to identify
the boundary of the read zone each time the sound stops. Continue moving the
tag to various locations until the read zone is fully marked.
14. You can now connect the outer marks to draw the outer boundary of the read
zone.
Figure 4-25 is a view of a sample read zone within a controlled lane. The outer X
marks show the outside edges of the read zone.

15. Standing at the farthest point of the pattern, walk toward the Encompass 4 Reader
or antenna and listen for a continuous sound from the audible tester. If the sound
is not continuous, it could indicate a weak or “patchy” RF pattern. See “FineTuning and Verifying the Read Zone” on page 8-19 to adjust the read zone.

General Software Information
This chapter provides software-related information for the Encompass® 4
Reader System.
This chapter presents various software-related topics arranged in alphabetical order by
subject. In addition to this chapter, see Chapter Chapter 6, “Communications Protocols,” and Chapter 7, “Commands for more information.
Command Entry Conventions
All Encompass 4 Reader commands are preceded by the start-of-message character
(#). The end-of-message sequence expected from the host is a carriage return (CR).
The Encompass 4 Reader terminates messages with a return and a line-feed (CR/LF).
For example, the command #01 Switch To Command Mode is typed as follows:
#01
where  is the Enter or Return key.
Some command characters may be represented by the letter N. This letter indicates
you are to supply a value. Maximum valid entries are the numbers 0 through 9 and the
uppercase letters A through F. These letters allow for as many as 16 available user
responses and are based on the hexadecimal numbering system.
Commands have at least two characters following the # character. Table 5-1 shows the
basic structure of a four-character command.
Table 5-1 Four-Character Command Structure
#1005 Set Baud Rate To 9600 Baud
All commands are preceded by the # character.

a second digit of 0 apply to the main port.
The command digit. In this example, the 0 indicates that this command
affects the baud rate.
5-3
Encompass 4 Reader System Guide
Table 5-1 Four-Character Command Structure (continued)
#1005 Set Baud Rate To 9600 Baud
Indicates the setting. Normally this is a variable and is usually a
hexadecimal value from 0 through F. In this example, 5 sets the baud
rate to 9600, the factory setting. In some commands, this digit may be
a four-place hexadecimal string or a character string.
Command Response Conventions
Like the Encompass 4 Reader commands, responses are preceded by the # character.
Many Encompass 4 Reader commands respond with #Done or #Error indicating
the command was or was not recognized and completed. Other commands respond
with a four-character identifier followed by one or more values.
Table 5-2 shows an example of a command/reply sequence. This example assumes
that an Encompass 4 Reader with serial number SN97001P running version X.XX
software is connected to a PC running a terminal emulation software package such as
Windows Hyper Terminal or Procomm Plus. The command sequence verifies that
communications are working correctly.

#Done 
In command discussions, Encompass 4 Reader response characters may be shown in
brackets < >. The use of brackets indicates that the response is a value in the range of
characters. The brackets are not part of the response. For example, the response to
command #520 Display Power Fail Bit is either a 0 or a 1. In the command discussion, the response is shown as:
#PWRB <0-1>
with actual Encompass 4 Reader response being one of the following:
#PWRB 0
#PWRB 1
In this example, PWRB is the four-character identifier for power fail bit, and the 0 or 1
is the value. All spaces shown in the response are actual spaces sent from the Encompass 4 Reader. In this example, one space is between the letter B and the number.
5-4
General Software Information
Operating Parameters
The Encompass 4 Readers maintain their operating parameters in non-volatile memory (NVRAM) so that the parameters are preserved after a power-down sequence.
Caution
To save user parameter changes to NVRAM, you must send command #00 before
powering down the reader.
Power Fail
The system maintains a power fail flag. The host transmits command #520 Display
Power Fail Bit to determine if a power down has occurred. This flag is cleared by both
command #63 Reset Reader and command #65 Reset Power Fail Bit.
Program Download
Program download stores the Encompass 4 applications software into the reader’s
flash memory. Program download is used to install program upgrades, add features,
and to recover from corrupted program data.
Note: Program download is a hosted process. Exercise caution so that you don’t inadvertently enter download mode.
Download Considerations
You should consider the following factors when performing program download:
•
The Encompass 4 Reader does not process tags while in download mode.
•
The Encompass 4 Reader does not accept any program data unless a successful
erase of flash memory has been performed before transmitting the data. Erasing
the flash memory typically takes two seconds.
•
Exiting from download mode re-executes startup. If the new software has been
loaded without errors, the Encompass 4 Reader comes up in data mode. If a flash
checksum error is detected, the Encompass 4 Reader reenters download mode and
transmits a sign-on message with a boot version of 0.00x and without a serial
number.
Note: The Encompass 4 Reader uses default communications parameters when operating in download mode – 38400 baud, 8 data bits, 1 stop bit, no parity, basic protocol
– and does not echo commands.
Download Procedures
5-5
Encompass 4 Reader System Guide
If TransCore releases a new version of the Encompass 4 Reader software or if the
Encompass 4 Reader seems not to be working properly, you may need to download
the software to the Encompass 4 Reader. Contact technical support or your TransCore
Encompass 4 Reader sales representative.
Startup
Upon startup, Encompass 4 Reader’s transmit a sign-on message or a boot ROM failure message.
Sign-On Message
If startup is successful, the sign-on message appears as follows:
Model E4 Series [software version] SNYYYYYY
[Copyright notice]
where YYYYYY is the serial number assigned to the 4800 Reader unit being used.
Serial number 000000 is the default setting and is not a valid number. If this number
appears in the sign-on message, the serial number has never been stored into reader
memory. The serial number must be assigned by factory-authorized personnel using
command #695S...S Set Serial Number. Because only six digits are allowed in
the software, when setting the serial number skip the fourth (middle) digit of the
seven-digit number shown on the reader label.
If the flash memory checksum does not indicate verification, the sign-on message
appears as follows:
Model [E4] Ver 0.00x
[Copyright notice]
Boot Failure Message
The software performs a checksum function on itself. The function returns a specific
value for the particular version of software. If the value returned is not correct, the
boot ROM checksum assumes that locations have been corrupted and a failure condition exists. If the boot ROM checksum is not correct, a boot failure message is transmitted. If the failure message does not transmit, a communications error has occurred
or the boot failed to the extent that it cannot transmit the failure message.
If the failure message version number equals 0.00 and no serial number exists, the
flash memory checksum has failed, and the Encompass 4 Reader is operating out of
boot ROM. In this case, the Encompass 4 Reader automatically enters download mode
and waits for a new program to be loaded into the flash memory. Follow the instructions in “Program Download” on page 5-5 to download a new program.
5-6
General Software Information
Tag/Message Buffer
In basic communication protocol, the Encompass 4 Reader does not provide tag memory storage beyond the quantity required for uniqueness checking. This feature allows
adequate buffering of tag data under normal operating conditions. The Encompass 4
Reader cannot operate as a stand-alone component. When the buffer fills, subsequent
tag IDs will be lost.
In error correcting protocol (ECP), a buffer of up to three additional tag reads will be
held in case a host system is unable to acknowledge tag reads in real time.

Chapter 6
Communications Protocols
This chapter describes the communications protocols for the
Encompass® 4 Reader.
Introduction
The Encompass 4 Reader supports the following communications protocols:
•
Basic
•
Error correcting protocol (ECP)
•
Data inquiry
The following protocol information provides reference information relevant to developing host software.
Communications are performed using the 7-bit ASCII code with optional parity, thus
providing easy setup, testing, and diagnostics with standard ASCII terminals and
serial printers. Parity must be enabled to achieve the specified undetected error rate.
Each message is framed within the start-of-message (som) and end-of-message (eom)
characters so that the host computer can detect the beginning and end of each message. This convention is most important under marginal communications conditions
during which the host may receive extraneous noise-induced characters between
reader transmissions. In such instances, the host is capable of ignoring any messages
that do not conform to the som...eom frame sequence.
Both data mode and command mode require a two-way message interchange is when
using ECP. This interchange is completed by the message recipient returning a message acknowledgement to the message sender.
With ECP, all transmissions require a message. If a message is not received, the sender
will time out with the same effect as if it had received a negative acknowledgment
(from the host) or an Error message from the Encompass 4 Reader.
Software (XON/XOFF) flow control is optionally supported. Be careful in the use of
XON/XOFF since noise-induced characters may be interpreted by the Encompass 4
Reader as the XOFF character, which would suspend reader output without information reaching the host computer. For more information see “Software Flow Control”
on page 8-19.
Note: TransCore recommends that XON/XOFF flow control be disabled while using
ECP.
6-3
Encompass 4 Reader System Guide
Basic Protocol
With basic protocol, messages sent to and from the Encompass 4 Reader and the host
are transmitted without error checking. For each host transmission, the Encompass 4
Reader returns a Done or Error message to the host.
When the host computer is physically close to the Encompass 4 Reader and no sources
of interference exist, the basic protocol provides reliable communications.
The host must be ready to receive reader-transmitted messages because in basic protocol the Encompass 4 Reader does not wait for the host to acknowledge a message
before transmitting the next message. If necessary, the host may halt reader transmissions by using software or hardware flow control. Refer to Chapter 8 for flow control
information.
Error Correcting Protocol
When the quality of data communications is imperative or may be suspect, you can
invoke ECP to ensure the integrity of data transmitted between the Encompass 4
Reader and the host.
Note: TransCore recommends that basic protocol (not ECP) be used when commands
are entered manually at the keyboard.
Wiegand output is automatically disabled when the reader is put into ECP mode.
Error correction is accomplished with the use of a cyclic redundancy check (CRC)
value that is based on the message data. The originator (reader or host) calculates the
CRC value of a message and includes it in the transmitted message.
The recipient (reader or host) also calculates a CRC value for the received message. If
the transmitted message data is correct, the CRC value calculated by the recipient will
agree with the CRC value calculated by the originator. If the CRC values do not agree,
the recipient rejects the message.
Message sequence numbers are also included when using ECP. These sequence numbers are checked to determine if the message received has the correct sequence number; if not, the recipient rejects the message.
Since the seven-bit ASCII code is used and there are eight data bits per character, the
eighth bit can optionally be used to support parity. Where parity is selected, the CRC
value calculation includes the parity of each character in the calculation of the CRC
value.
Parity is required to achieve the most reliable communications. If parity is enabled,
both the Encompass 4 Reader and the host must issue a message if any received character has a parity error. However, the message must not be transmitted before receipt
of the eom character. In this case, the Encompass 4 Reader will issue an Error message, and the host computer will issue a negative acknowledgment message.
6-4
Communications Protocols
Data Inquiry Protocol
Data inquiry protocol is a basic protocol option that allows the host to control
transmission of reader tag data. The selection of data inquiry protocol affects data
mode operation. As the Encompass 4 Reader acquires tags, it buffers them but does
not transmit them. Instead, the host must poll the Encompass 4 Reader for each tag by
sending a CTRL-E character (hex 5 digit). The Encompass 4 Reader transmits one
message (tag ID or report data) for each CTRL-E it receives until the buffer is empty.
Each tag request message sent by the host consists only of the CTRL-E character; no
som or eom characters are sent. Encompass 4 Reader data transmission (tag ID and
report data) format is the same as for basic protocol.
Selection of data inquiry protocol does not affect command mode operation.
Basic Protocol and ECP Format
Note: In the following text, the symbols < and > are used to represent required variable message data, and the symbols [and] are used to represent optional data. These
symbols are not part of the message syntax.
Reader Transmissions
The basic protocol format and the data inquiry protocol format are as follows:

The ECP format is as follows:

where

Start-of-message (ASCII # character)

Sequence number (ASCII hex) that represents an even number in
the range 0–9, A–F (0, 2, 4, 6, 8, A, C, E). The Encompass 4
Reader maintains the number. The host must acknowledge reader
transmissions by sending an ACK message with the same
sequence number received from the Encompass 4 Reader. The
Encompass 4 Reader updates its sequence number upon receipt of
a valid host ACK. If an ACK is not received, the Encompass 4
Reader retransmits the message. A reader transmission sequence
is not considered complete until the Encompass 4 Reader receives
an ACK and updates its sequence number.

An ASCII string up to 72 characters long. This string may contain
tag data, a presence without tag report; an input status change
report; an Error06, Error07, Error08, or Error11
6-5
Encompass 4 Reader System Guide
message; or a sign-on message. Auxiliary data may also be
included.

Field containing four ASCII digits that represent the 16-bit CRC
value calculated on the message. The CRC value is calculated on
bytes between the som character and the first  byte.
When the host receives a properly framed message, it can
calculate a 16-bit CRC value. The calculation is applied to the
character string that immediately follows the  and that
ends with the character immediately preceding the first 
character.
The transmitted CRC value can then be compared with the binary
equivalent of the received  characters. If the transmitted
and received CRC values do not match, the recipient assumes the
message was received in error, and transmits a NAK message
response.

End-of-message characters (ASCII CR and LF). The system
includes both a carriage return (CR) and line feed (LF) to
facilitate the use of terminals and printers.
If the host receives a  character in the middle of a data
message, the message in progress is aborted. The assumption is
that an  was lost and the Encompass 4 Reader is in the
process of retransmitting the previous message.
ECP Host ACK/NAK Response
With ECP, the host computer responds to all data message transmissions from the
Encompass 4 Reader using the following acknowledgment or negative acknowledgment response format.

where
6-6

Start-of-message (ASCII # character)

An echo of the sequence number received from the Encompass 4
Reader. The sequence number should correspond to the data
message that is being positively or negatively acknowledged by
the host. If the Encompass 4 Reader receives an ACK message
with the incorrect sequence number, the data message is
retransmitted.
Communications Protocols
The host computer resets the anticipated data message sequence
number to that of the Encompass 4 Reader before
communications can resume without error.

ASCII @ character for ACK response; ASCII ? character for NAK
response

CRC value for the message

End-of-message character (ASCII CR)
The Encompass 4 Reader sets a user-programmable timeout delay at the time each
message is transmitted based on command #612NN Set Error Correcting Protocol
Timeout, where NN = timeout delay. To disable the timeout delay for diagnostic purposes, issue the command #612FF Disable Error Correcting Protocol Timeout.
If the timeout delay expires before the Encompass 4 Reader receives an ACK or NAK
message from the host, a logical NAK condition will be declared. If the Encompass 4
Reader receives a NAK or timeout, the reader retransmits the data message.
When the Encompass 4 Reader receives an ACK message, the system software treats
the message as having been properly received by the host. The software increments
the sequence number, and advances pointers to the next message in the Encompass 4
Reader’s message queue to prepare for sending the next message.
Switch to Command Mode Request
The host computer may issue command #01 Switch to Command Mode while in data
mode.
The basic protocol format is as follows:

The ECP format is as follows:

where

Start-of-message (ASCII # character)

Sequence number generated by the host computer separately
from that appearing in data messages transmitted by the
Encompass 4 Reader

Switch to command mode (ASCII characters 01)

6-7
Encompass 4 Reader System Guide
Host Transmission
The host computer initiates synchronous communications between the Encompass 4
Reader and the host. The host begins a sequence by issuing a command; the Encompass 4 Reader responds accordingly.
The data inquiry protocol format is as follows:

The basic protocol format is as follows:
[]
The ECP format is as follows:
[]
where

ASCII Control E (hex 5 digit). When in data inquiry mode, each
transmission of a CTRL-E by the host causes the Encompass 4
Reader to transmit one tag ID.

Start-of-message (ASCII # character)

Sequence number (ASCII hex digit) that represents an odd
number in the range 0–9, A–F (1, 3, 5, 7, 9, B, D, F). The host
should use odd sequence numbers in its command since the
Encompass 4 Reader uses even sequence numbers in its
transmissions. This method eliminates the possibility of a
synchronous host command and an asynchronous reader
transmission having the same sequence number.
Upon receiving a host command in ECP, the Encompass 4 Reader
replies using the command’s sequence number in its response.
Therefore, the host computer updates its sequence number upon
receipt of a valid reader message. If the sequence number is not
updated before transmission of the next command, the
Encompass 4 Reader will not service the new command; it will
retransmit its previous message. A command/message sequence
is not complete until the host updates its sequence number.
6-8

Command code, a string that contains from two to four ASCII
hex characters

Optional data field, an ASCII string of as many as 20 characters
in length. For example, the store hardware configuration string
command is #696S...S or command #696 Store Hardware

Timing and Synchronization
The ECP is largely independent of baud rate. The timeout delays previously described
are a function of baud rate.
The Encompass 4 Reader supports an ECP timeout, which applies equally to both
transmit and receive.
The receiver’s minimum timeout delay equals the time to transmit/receive the longest
anticipated message at the current baud rate setting. Additional margin should be
included for idle periods between characters; for example, processing overhead, if
any. The timeout delay period can be expressed as follows:
rec (ms) = L x [char + idle]
where
char (ms)
1000 x [ Bc / Rb ]
Bc
Bits per character, typically 10
Rb
Baud rate, 1200–38.4 K
Length of message in characters
idle
Maximum idle period between characters (ms)
Note: The Encompass 4 Reader supports baud rates between 1200 and 38.4 K.
Likewise, the sender must set a timeout delay equal to the delay of nine characters at
the current baud rate setting. For example, the time required to shift out the 
character plus the time to shift in the ACK or NAK message to be received plus a processing allowance for the receiver to process the message and check for error conditions.
Thus, the sending timeout delay can be expressed as follows:
send (ms) = 9 * char + errchk
where
errckh (ms)
Processing period to perform error checking by receiver
The host computer can remotely set the Encompass 4 Reader’s communications
parameters while in the command mode, but TransCore does not recommend this
action if communications conditions are marginal.
After the Encompass 4 Reader receives new communications parameters, the Encom-
6-12
Communications Protocols
pass 4 Reader issues the Done message and switches to the new configuration immediately. The host computer switches its communications parameters immediately after
the transaction is complete.
As noted, the message initiator, such as the Encompass 4 Reader in data mode and the
host computer in command mode, starts a timeout counter at the time a message is
transmitted. If the timeout expires before receiving an acknowledgement message, a
logical NAK condition is declared, and the initiator assumes the message was received
in error. In this instance, the message is retransmitted until an acknowledgement message is received.
The message recipient, such as the host computer in data mode and the Encompass 4
Reader in command mode, starts a timeout counter when a  character is
received. If the timeout expires without the receipt of an , the message acquisition is aborted (reset), and the receiver waits for the next  character.
If the message recipient receives a second  character before an  character, the message acquisition is aborted (reset), and retransmission of the previous message is assumed to be underway.
These strategies allow for recovery during periods when communications are marginal
or completely lost.
Note: It is important that the host computer limit the period during which the Encompass 4 Reader remains in command mode to avoid losing tag IDs. RF is off in command mode and no tags can be read.
Reader-Addressed Failure Conditions
The Encompass 4 Reader addresses the following failure conditions.
Illegal Sequence Number (not in the range 0–9, A–F)
If the Encompass 4 Reader detects an illegal sequence number in a host command
message, it discards the received message and sends no response. If it receives an illegal sequence number in an ACK message, it responds as if a NAK had been received
and retransmits the data.
Wrong Sequence Number
If the Encompass 4 Reader receives the wrong sequence number in an ACK message,
it responds as if a NAK had been received, and it retransmits the data.
Incorrect CRC
If the Encompass 4 Reader detects an incorrect CRC value in a host command message, it discards the received message. No response is sent. If it receives an incorrect
CRC value in an ACK message, it responds as if a NAK had been received, and it
retransmits the data.
Illegal Command
6-13
Encompass 4 Reader System Guide
If the Encompass 4 Reader receives an illegal command, it returns its standard Error
message.
6-14
Communications Protocols
Transmission Timeout
If the Encompass 4 Reader transmits an asynchronous message and the host does not
send an ACK before the ECP timeout occurs, the Encompass 4 Reader retransmits the
message.
Receive Timeout
If the Encompass 4 Reader receives a  but does not receive a matching 
before the ECP timeout occurs, it discards the incomplete message and resets its
receiver.
Asynchronous Message/Command Message Collision
If the Encompass 4 Reader transmits asynchronous data at the same time that the host
sends a command, the Encompass 4 Reader gives priority to receiving the command.
It processes the command and sends a message before it retransmits the asynchronous
data.
Host-Addressed Failure Conditions
The host computer addresses the following failure conditions.
Illegal or Wrong Sequence Number
If the host detects an illegal or wrong sequence number in a reader response, it retransmits the command with the same sequence number. If the host detects an illegal
sequence number in an asynchronous reader transmission, it sends a NAK message.
Incorrect CRC
If the host detects an incorrect CRC value in a reader message, it retransmits the command with the same sequence number. If the host detects an incorrect CRC value in an
asynchronous reader transmission, it transmits a NAK message.
Transmission Timeout
If the Encompass 4 Reader does not respond to a host command within a specified
interval, the host software retransmits the command with the same sequence number.
Receive Timeout
If the host receives a  but does not receive a matching  within a specified
timeout interval, it discards the incomplete message and resets its receiver.
Asynchronous Message/Command Message Collision
If the host receives an asynchronous reader transmission at the same time it transmits
a command, it ignores the asynchronous message and waits for the Encompass 4
Reader’s response. The Encompass 4 Reader retransmits asynchronous data after it
transmits the command message.
6-15
Encompass 4 Reader System Guide
ECP Reliability
An undetected error is defined as a message having incorrect data or status but no parity or CRC errors. An error transaction is defined as a message having either a parity
or CRC error. Laboratory testing indicates an undetected error rate of less than one
undetected error per 1,000,000 error transactions with parity enabled.
To ensure this error rate is not exceeded, the host must enable parity and adhere
closely to the timing specifications discussed previously in this chapter in the “Timing
and Synchronization” section.
CRC Calculation
The CRC used by the ECP is based on a 16-bit algorithm. The algorithm, as implemented, operates on eight-bit characters, for example, seven-bit ASCII character plus
one optional parity bit. The 16-bit result is converted to four ASCII hex characters and
is appended to messages transmitted by the Encompass 4 Reader.
The Encompass 4 Reader accepts four ASCII < ` > characters (60 hex) as a wild card
CRC value in lieu of a valid four-character CRC value to facilitate testing and diagnostic checkout.
The Encompass 4 Reader implements the algorithm with a 512-byte lookup table to
reduce the processing overhead requirements.
To simplify the implementation of the CRC algorithm by host software developers,
several examples of the calculation are provided in C source code on the following
pages. The calculation may be performed with or without a lookup table, depending
on the trade-off between code memory and processing overhead.
Example 1 presents an example of a function (CALCCRC) that calculates the CRC
value through a call to a separate function (UPDCRC).
unsigned short calccrc(char *message)
{
unsigned short crc = 0;

Manually Disabling ECP for Maintenance
Under certain conditions, communications between the host and Encompass 4 Reader
may be lost temporarily and maintenance may be required. The reader or host is sending out a message and waiting for an acknowledgment. When the acknowledgment is
not received, the message is sent again. Additional messages are also buffered. Often
the first indication that the Encompass 4 Reader software is in an ECP “loop” is when
the user/technician sees a recurring display of the same message repeated over and
over again on the monitor. The procedure described in the following paragraphs
enables the maintenance technician to change configuration or test tag reading manually.
Assuming that the ECP timeout is at the factory default of 12.7 seconds (or other value
that allows enough time for the commands to be manually entered) the following command sequence may be used to break out of an ECP loop. This command sequence
uses four ASCII < ` > characters (60 hex) as wild card CRC values.
Note: The ASCII <`> character (60 hex) is commonly located on the ~ key.
You must acknowledge existing messages by issuing commands with the generic format:
#x@‘‘‘‘
where
Start-of-message character
Message sequence number. This must be the same as the
sequence number of the message being acknowledged
ACK (acknowledgment character)
<‘‘‘‘>
Wild card CRC value for the message

End-of-message character
The following is a typical sequence after power-on limiting buffered messages.
Note: Ensure that no tags are in the field when you are performing this troubleshooting procedure.

To avoid damage to the Encompass 4 Reader that uses an external antenna, ensure
that you have connected the antenna or a dummy load to the reader before applying

Chapter 7
Commands
This chapter discusses the host-transmitted commands that are used to
control the Encompass® 4 Reader configuration and operation.
Introduction
The Encompass 4 Reader is delivered from the factory with specified default settings
that determine how the reader operates. Commands transmitted by the host computer
can change the default settings and control additional features. The commands can be
transmitted by manually entering the commands at the host keyboard if the host is in
terminal emulation mode. The Encompass 4 Reader can also communicate with
ASCII terminals.
Note: If you are using Wiegand mode, you must connect the PC or laptop to the
Encompass 4 Reader using the RS–232 or RS–422 interface and a terminal emulation
program to send commands to the reader. You can leave the Wiegand interface connected during this procedure.
Operating Modes
The Encompass 4 Reader has three modes of operation: data mode, command mode,
and download mode. The software for the Encompass 4 Reader contains two separate
programs — boot and application. The boot program has control of the Encompass 4
Reader on startup and when operating in download mode. The application program
has control of the Encompass 4 Reader during data mode and command mode operation and holds the application code. Together, they control the Encompass 4 Reader in
the three modes of operation.
Data Mode
The Encompass 4 Reader is in the data mode upon power-up. While in the data mode,
the Encompass 4 Reader sends all communications as data messages, such as tag IDs
and reports, to the host computer. Reports provide information on input status changes
(input0 and input1), a presence without tag report, and buffer overflow information.
The host computer can send only two commands to the Encompass 4 Reader while in
data mode:
•
Command #01 Switch To Command Mode changes the Encompass 4 Reader
from the data mode to the command mode. See “01 Switch to Command Mode”
on page 7-5.
7-3
Encompass 4 Reader System Guide
Note: The Encompass 4 Reader transmits ID codes to the host computer when the
Encompass 4 Reader is in data mode. If the Encompass 4 Reader remains in the command mode with tags passing through the read zone, all tag IDs are not reported.
Command Mode
While the Encompass 4 Reader is in the command mode, the host computer sends
commands to the Encompass 4 Reader that can be used to control the operation and
configuration of the reader. After the Encompass 4 Reader receives a command, it
transmits a command response message. Typically, the command message
contains Error, Done, or data relating specifically to the command request. These
messages may be of variable length since some commands require information as part
of the message; for example, Display Wiegand Mode Status.
Communications can be lost if the host computer attempts to send certain commands
under marginal communications conditions. For example, if the host computer transmits the command request to change the baud rate and the Encompass 4 Reader properly receives the request and transmits the Done message, one of the two following
conditions may occur:
•
If the host computer receives the Done message, then both the host and the
Encompass 4 Reader switch to the new baud rate, and communications are maintained.
Note: In many applications, the host must be set to the new baud rate as it will not
change automatically.
Note: The Encompass 4 Reader changes the baud rate immediately after issuing the
Done message.
•
However, if the host does not receive the Done message transmitted by the
Encompass 4 Reader, the host assumes that the command was not properly sent
and does not switch to the new baud rate, causing a loss of communications.
Caution
The host computer should not attempt to change communications parameters or
protocols during marginal communications conditions; otherwise, a loss of communications can result.
Download Mode
In download mode, the Encompass 4 Reader allows the host to download new software.
While in download mode, the reader communications port parameters are fixed at the
following factory-default settings: 38400 baud, 8 data bits, 1 stop bit, no parity, software flow control (XON/XOFF), basic protocol.
While in download mode, the Encompass 4 Reader turns RF off, does not process
7-4
Commands
tags, and does not echo host commands.
Command List
Reader commands are divided into groups based on primary function. The following
sections provide information about each command in command number order. Refer
to Appendix D for listings of commands in numerical and alphabetical order.
In the following text, the symbols < and > represent variable message data. These
symbols are not part of the message syntax.
Hex digits (0–9, A–F) in either uppercase or lowercase characters may be used in data
strings and for hex digits A–F.
Reader Mode Control — Command Group 0
Group 0 commands control reader mode. The mode determines whether the reader is
transmitting data to or receiving data from a host computer or terminal.
00 Switch to Data Mode (Factory Default)
Command #00 switches the reader to data mode, which allows the reader to transmit
tag data (ID codes) to the host. In addition to switching the reader to data mode, command #00 automatically saves to non-volatile memory (NVRAM) any user parameters that had been changed during the command mode session. The reader enters data
mode on power up.
Caution
To save user parameter changes to NVRAM, you must send command #00 before
powering down the reader.
While operating in data mode, the reader accepts the following commands:
•
Command #01 Switch to Command Mode
Reader response:
Done
01 Switch to Command Mode
Command #01 switches the reader to command mode, which allows the reader to
accept commands from a host or terminal. While in command mode, the reader turns
RF off and does not acquire tags.

Commands
Command #30N selects the option of appending the time and date to transmitted IDs,
error messages, presence without tag reports, and input status change reports. The
factory default setting is time and date appended (command #302).
The reader returns an Error message if its tag buffer contains data. The reset reader
command #63 may be transmitted to clear the buffer; however, tag ID data will not be
reported. If this is unacceptable, allow the buffer to empty before re-issuing append
time and date command #30N. Append Time and Date commands are shown in Table

Command #320 is a factory-set default that disables the EAC (embedded application
code) page append.
Reader response:
Done
#321 Enable EAC Page Append
Note: Note: This functionality was added to the Encompass® 2 Reader to handle a
special unique customer requirement, and is retained in the Encompass 4 Reader for
full backward compatibility.
Command #321 selects the option to append an additional predefined 8 bytes of data
to be read from an eGo® or eGo Plus tag when the reader is in ID only mode (i.e., not
eATA) and multitag sort is enabled. The additional bytes that are read from the tag are
in locations 10 through 17.
The reader transmits the message with EAC page append as follows. The EAC append
data occurs before time and date append data and AUX append data if they are
enabled.

Commands
ID Filtering — Command Group 4
Group 4 commands set criteria for filtering (buffering or discarding) ID codes. These
commands are useful for eliminating duplicate ID codes and selecting the type of tags
read by the Encompass 4 Reader.
40 Transmit All ID Codes
Command #40 instructs the reader to transmit all IDs without regard for uniqueness.
This command can be useful when tuning the lane and mapping the footprint or performing diagnostics.
After diagnostics are complete, you may want to reinstate the uniqueness check using
command #410N Select Unique ID Code Criteria.
Reader response:
Done
410N Select Unique ID Code Criteria (Anti-passback Feature)
Command #410N instructs the reader to buffer and transmit ID codes according to
the following test: an ID is read if previously decoded IDs have changed value at
least N+1 times since the new ID was last received. IDs that do not pass the test are not
read. The factory-default setting is command #4100, which selects a separation of
one ID. Variable N specifies ID separation as shown in Table 7-6.
Table 7-6 Unique ID Code Criteria
Command
Uniqueness Criteria
4100
Separation of 1 ID (factory default)
4101
Separation of 2 IDs
4102
Separation of 3 IDs
4103
Separation of 4 IDs
Each time the reader receives a tag ID, it compares the ID with the contents of a comparison register. This register contains the following two items:
Item 1
Most recently acquired ID
Item 2
Second-most recently acquired ID
Item 3
Third-most recently acquired ID
Item 4
Fourth-most recently acquired ID
When the uniqueness filter is set to separation of one ID, the newly acquired ID is
transmitted only if it is different from the first item. Separation of two IDs allows
transmission if the new ID is different from Items 1 and 2 in the comparison register.
Separation of three and four IDs transmit the new ID only if it is different from the
7-11
Encompass 4 Reader System Guide
first three and the first four items, respectively.
Note: A new ID can fail the filter test and not be transmitted; however, it remains
stored in the comparison register.
The uniqueness test’s time limit is set by Command #441. If an ID is buffered, it will
not be accepted again unless it arrives at the reader more than the programmed time
interval from the previous arrival or until the receipt of one or more other IDs reset the
uniqueness.
Reader response:
Done
420N Select Valid ID Code Criteria
Command #420N directs the reader to validate an ID received only after it has been
obtained a specified number of times in sequence. Values for N are 0 through 3 (Table
7-7). The factory setting is one acquisition (N = 0).
Table 7-7 Select Valid Code Commands and Frames
Command
Valid Code Frames
4200
1 (factory default)
4201
4202
4203
The validation procedure is executed before the unique ID test (Select Unique ID
Code Criteria [#410N] commands). IDs that do not pass the validation test are not
reported.
For example, command #4203 specifies that the same ID must be obtained from the
antenna/RF module 4 times in succession before it is considered for the uniqueness
test. This feature is useful in installations where RF reflections may cause a single tag
to be read multiple times or where an occasional ID might be read from fringe areas
440 Reset Uniqueness
Command 440 causes the ID filtering process set by Select Unique ID Code Criteria
(#410N) to restart. It is used in conjunction with the Variable Timeout #44N) commands. This command provides a method to end all uniqueness timers.
44N Set Uniqueness Timeout
Places a time limit on the uniqueness criterion set by Select Unique ID Code Criteria
(#410N). The parameter N sets the number of minutes on the timeout clock. The factory setting is two minutes (N = 1).

Entering these commands effectively expires the timeout clock, which erases all current IDs in the comparison register. In effect, the first ID that is acquired after the
clock expires always appears to be new and is stored. Newly acquired IDs are only
tested against IDs that are registered after the clock resets.
The timeout clock is continually reset (does not expire) as long as the reader receives
the same tag ID. For example, assume that the timeout clock is set for 2 minutes and
there is a railcar parked on a siding in front of the reader. Without this continual reset
feature, the railcar’s ID would be reported every 2 minutes (each time the timeout
clock expired).
450 Disable Wiegand Mode (Factory Default)
Command #450 is a default set in the factory to disable Wiegand mode.
Reader response:
Done
451 Enable Wiegand Mode
Command #451 enables Wiegand mode, which allows the reader to transmit data in a
format that emulates the output of a magnetic card reader.
In Wiegand mode, the reader transmits Wiegand-formatted tag data through the Wiegand interface and ASCII data (the reader accepts reader commands and responds)
through the serial port interface. The reader outputs data from Wiegand-programmed
tags via the Wiegand interface (the red/blue pair for data1/data0; yellow/black pair for
logic ground). Tags that are not Wiegand-formatted are not transmitted through the
Wiegand interface or the serial port when in Wiegand mode, although the tag lock
relay is activated on any tag acquired.
Reader response:
Done
452 Disable Tag Translation Mode (Factory Default)
Command #452 disables tag translation mode. Incoming full-frame tags will be

If the reader is configured for software flow control (XON/XOFF), it stops transmitting if it receives an XOFF character (host software command 13H). It does not
resume transmitting until it receives an XON character (host software command 11H).
If the reader is configured for hardware flow control (RTS/CTS, request to send/clear
to send), it stops transmission if it detects that the CTS line is no longer asserted. It
resumes transmission when this line is asserted again.
Note: TransCore recommends that XON/XOFF flow control be disabled while using
the ECP.
6170 Disable Echo Mode
Command #6170 disables the reader’s echo of received host commands. If operating
in basic protocol or data inquiry protocol, the reader echoes by default. As the reader
receives a host command, it echoes each character of the command. Once the entire
command has been received and processed, the reader transmits its response. If echoing is disabled with command #6170, the reader does not echo the command, but
only transmits its response. The reader never echoes while in ECP or download mode
operation.

642NN Select RF Operating Frequency
Caution
The authorized bands in the U.S. for CW frequency (i.e., ATA only) is 902.25 to
903.75 MHz and 910.00 to 921.50. The authorized frequency band for modulated
frequency is 911.75 to 921.75 MHz.
Note: RF frequency can be set for backward-compatibility using command #642NN
or for the newer 250-kHz step method using command #647XXX.
Command #642NN sets the reader RF frequency from 902 to 928 MHz in 500-kHz
steps, where NN is a hexadecimal value from 00 to 34. After the reader’s frequency is
set, the value is stored in battery-backed RAM (non-volatile RAM, NVRAM). This
value is NOT altered by power-down, loading default parameters, or a flash download
of new software (there is no default frequency value). It can only be changed by
issuing command #642NN.
Additionally, if the NVRAM becomes corrupted, the correct operating frequency cannot be guaranteed. In this circumstance, the RF section will shut down and the reader
will send an error message to the host (Error 06). Until the frequency is reset using
command #642NN after NVRAM corruption, the unit will display the same error
message every time it is powered up or if an attempt is made to enable the RF (by host
or by external sensor). The commands to set the RF frequency are listed in Table 7-14.

646XX Set IAG RF Attenuation
Command #646XX sets the IAG attenuation control for the output RF power where
XX is a hexidecimal value from 00 to 0F. Setting 00 (0 dB) is the maximum power
setting and 0F (15 dB) is the minimum power setting. The default attenuation value is
04.
647XXX Select RF Operating Frequency
Command #647XXX sets the reader RF from 860 to 930 MHz in 250-kHz steps,
where XXX is a hexadecimal value from 000 to 118. After the reader’s frequency is
set, the value is stored in non-volatile RAM (NVRAM). This value is not altered by
power-down.
If the NVRAM becomes corrupted, the correct operating frequency cannot be guaranteed. In this circumstance, the RF section shuts down and the reader sends an
Error06 message to the host. Until the frequency is reset using command #647XXX,
the unit displays the same error message every time it is powered up or if an attempt is
made to enable the RF by host or by external sensor.
The commands to set the RF operating frequency are presented in Table 7-16.

#648NN Set Synchronization Output Delay Time
Command #648NN sets the time in milliseconds by which the reader is delayed before
sending a synchronization pulse on the RS–485 synchronization bus to all other readers connected on the bus. Entering a value of #64800 (factory default) disables this
feature. Entering #64801 through #648FF sets the reader countdown time from 1 and
255 milliseconds. If the reader gets a pulse from another reader before its own time
period expires, it first executes all of the enabled tag protocols, then restarts its countdown timer. The reader on the bus with the smallest entered value becomes the master
and all readers with a larger entered number become slaves. Any reader on the bus can
become the master. The master does not necessarily have to be on one of the ends of
the synchronization bus, but the installer must exercise caution to ensure that every
reader on the bus has a different value.
When the master sends out the synchronization pulse all of the connected readers
begin the RF tag protocol transactions that have been enabled. This synchronization
7-40
Commands
feature primarily is designed to overcome some of the system-design RF interference
issues in reading IAG tags at locations having a dense population of readers and tags.
All readers on the bus require the same enabled tag protocols for synchronization to
work. Entering increasing values to all readers on the bus is required so that should a
break occur in the bus that is connecting all the readers, the next reader will take over
as master for the rest of the readers that are connected, and the system may work reasonably well until the cabling is fixed. Do not set the synchronization times too short,
as IAG tags are battery powered and their useful life can be diminished if the typical
traffic flow is slow moving, and the tag is activated continuously in the reader pattern.
Command #582 displays the synchronization output time.
The synchronization bus is wired by connecting all of the readers’ “V” (RS–485 synchronization minus) pins together and all of the readers’ “Z” (RS–485 synchronization
plus) pins together (Figure 7-1).
Figure 7-1 Example of Synchronization Bus Wiring
#649NN Set Synchronization Hold Off Time
Command #649NN sets the time in milliseconds that the reader will hold off after getting (or sending if it is the master on the bus) the synchronization pulse before it starts
to run its IAG tag sequence. This command is used in close combination with command #648NN. Command #649NN is applicable only if a value other than #64800 is
entered for #648NN and is used only when the IAG tag protocol is enabled. Entering a
value of #64900 (factory default) disables this feature. Entering a value between
#64901 and #6490A (hex value of 10 decimal) causes the reader to hold off starting its
tag protocol transaction for the time set between 1 and 10 milliseconds. This feature is
used to lessen the possibility of a reader reading an IAG tag that is activated by
another reader in the site. Because IAG tags are battery powered active transmitters,
their read zones can be much harder to control than for beam-powered passive tags.
The pattern also will vary greatly among tags depending on the condition of the individual tag battery. If this feature is used, each reader on the bus needs a value of
between #64901 and #6490A entered for the feature to work. As with the #648NN
command, the reader’s physical location on the bus is not critical, but TransCore recommends that the reader numbering follow a logical sequence. Using this command,
7-41
Encompass 4 Reader System Guide
more than 1 reader on the bus can have the same value, but TransCore recommends
using all 10 slots before reusing them. Command #582 displays the Synchronization
Hold Off Time.
Table 7-17 lists an example of a plaza having five Encompass 4 Readers in lanes
where multiple readers identifying the same tag would present a system problem. All
of the readers are cabled together on a synchronization bus (see Figure 7-1). The
example timing for #648NN is appropriate assuming IAG is the only protocol enabled
in all readers. The RF for all readers is set to 915.75 (#6470DF) and in this example it
is determined that an IAG attenuation setting of 9 dB (#64609) prevents a reader from
activating a tag in an adjacent lane.

Filter
Command #697 assigns the user-programmable GSE filter.
The command string is assigned according to the following format:

where
MM = The tag uses this mask to determine which of the eight Comparison Data bytes
are to be compared for the Group Select filter.
AA = This field is used by the tag to determine the start address in the tag memory for
the comparison data.
DD…DD = Comparison Data: an 8-byte field (16 characters) used by the tag as the
comparison data for the Group Select filter. The tag compares the data in this field to
data in tag memory beginning at the Start Address to determine if the tag will respond
to a reader Group Select request. Only the bytes having the corresponding bit set in the
GSE Mask is used for this comparison.
As an example, to configure a reader to have only tags with data in byte locations 10,
12, and 15 (decimal) with hexadecimal values “00,” “01,” and “02,” the following
command is used:
#697 A4 0A 0005014202024133
To understand how the data is interpreted, it is necessary to break down the GSE Mask
field, A4, into binary:
A4 = 1010 0100
This mask equates to the tag comparing the first, third, and sixth bytes of the Comparison Data to data in the tag beginning at address location 0A (10 decimal).
The Comparison Data field is broken down in bytes with the bytes corresponding to
the mask underlined in bold (for clarification):
Address: 0A 0B 0C 0D 0E 0F 10 11
Data: 00 05 01 42 02 02 41 33

for a period of time. This message is the same message that would be sent in response
to the #527 Display RF Status command. Enabling this function is helpful in some
sites where there may not be much tag activity, and the user wants an automatic way to
ensure the communication channel with the reader is still intact. With this function
enabled, the host system will get a message from the reader at least every three minutes.

puter to which the Encompass 4 Reader will be connected after testing and configuration are completed.
2.
Cycle the power on the Encompass 4 Reader.
Upon startup, the Encompass 4 Reader transmits a sign-on message, displayed on
the terminal emulation screen as shown in Figure 8-5, or a boot ROM failure
message.
Figure 8-5 Sign-on Message
The sign-on message appears as follows:
Model [software version] SNYYYYYY
[Copyright notice]
where YYYYYY is the serial number assigned to the Encompass 4 Reader skipping
the fourth character printed on the reader product label.
Serial number 000000 is the default setting and is not a valid number. If this
number appears in the sign-on message, the serial number has never been stored
into reader memory. Contact TransCore Technical Support.
If the flash memory checksum is not verifiable, the sign-on message appears as
follows:
Model [E4 BOOT] Ver 0.00 A
[Copyright notice]
If the failure message version number equals 0.00 E and no serial number exists,
the flash memory checksum has failed, and the Encompass 4 Reader is operating
out of boot ROM. In this case, the Encompass 4 Reader automatically enters
download mode and waits for a new program to be loaded into the flash memory.
Follow the instructions in “Program Download” on page 5-5.
Communications can also be verified by using the command sequence in 

Configuring the Encompass 4 Reader
Radio Frequency
Caution
The authorized continuous wave (CW) frequency band for the Encompass 4 Reader
in the U.S. is 902.25 to 903.75 MHz and 910.00 to 921.50 MHz and the authorized
modulated frequency band for the Encompass 4 Reader in the U.S. is 911.75 to
919.75 MHz. The RF for each Encompass 4 Reader at the site must be set according
to the frequency specified in the FCC site license. Only trained, authorized installation and maintenance personnel are permitted by FCC to set the RF.
By using the Encompass 4 Reader an authorized person can set the frequency within
the range from 902 to 928 MHz in 0.25 MHz steps. You can set the frequency by
using a terminal emulation program and issuing the frequency command, as discussed
in section “647XXX Select RF Operating Frequency” on page 7-39.
Note: For backward compatibility to existing controllers, you can set the RF operating frequency in 500-kHz steps using command #642NN.
To set the frequency range
1. Ensure that the host computer is in command mode.
2.
Enter command #647XXX – where XXX is a hexadecimal value from 000 to 118
– and press ENTER. See command “647XXX Select RF Operating Frequency”
on page 7-39 for a complete listing of the hexadecimal values and the
corresponding frequencies. For backward compatible frequency selection, see
command “642NN Select RF Operating Frequency” on page 7-35.
3.
To verify that the RF has been changed to the proper setting, type in command
#527 to see the current frequency setting.
Caution
Contact TransCore if your application requires a frequency outside of the authorized frequency range.
RF Transmission
The RF transmission can be controlled by one of the following methods:
•
Connecting a vehicle detector to the sense input0 circuit
•
The host sending software commands to the Encompass 4 Reader
As a factory default, the Encompass 4 Reader is configured to control the RF power
with a vehicle detector.
Figure 8-8 illustrates the methods of controlling RF sense output.
8-15
Encompass 4 Reader System Guide
Figure 8-8 Encompass 4 Reader RF Control Options
Vehicle Detector Controlling RF Transmission
The vehicle detector can be a loop detector, an infrared sensor, or an ultrasonic detector that is connected to sense input0 to turn on the Encompass 4 Reader RF transmitter. In Figure 8-8, Option A shows a vehicle detector controlling the RF transmitter.
This operation is preferred because the RF transmits only when a vehicle is in the
Encompass 4 Reader read zone. Command #641 Select RF-by-Input Control (factory
default) must be enabled.
To set the option of the vehicle detector controlling the Encompass 4
Reader
1. Ensure that the host computer is in command mode.
2.
Enter command #641. Press ENTER.
Leave the setting on RF-by-input control for normal operation.
Host Controlling RF Transmission
In Figure 8-8, Option B shows the host controlling the RF transmitter.
If the vehicle detector is connected to the host computer, as shown in Option B, commands #6400 RF Off and #6401 RF On sent from the host computer turn on and off
the Encompass 4 Reader RF transmitter.
Continuous RF Transmission
In Figure 8-8, Option C shows the test configuration controlling the RF transmitter. To
test the Encompass 4 Reader, as described in “Testing the Encompass 4 Reader Using
an Audible Circuit Tester” on page 4-5, you can turn on the Encompass 4 Reader RF
transmitter continuously by issuing command #6401.
8-16
Configuring the Encompass 4 Reader
You may also use command #6402 to turn on CW RF for diagnostic purposes. Entering this command transmits a continuous RF signal at the output frequency and attenuation level as specified in the respective associated commands until command
#6400 RF Off, #6401 RF On, or #641 Select RF-by-Input Control is received by
the reader. Tags are not read in CW mode. See “640N RF Control” on page 7-34 for
more information.
Sense Inputs
Both the RS–232 and RS–422 configurations used by the Encompass 4 Reader have
two sense inputs — sense input0 and sense input1. The default configuration uses
sense input0 as the presence detection device line. RF power is automatically turned
on only when the presence detection device (loop detector or other device) detects a
presence. Sense input1 is not used directly by the reader; it is used by the host computer to monitor an external device. The Encompass 4 Reader sense inputs are
designed to connect to a dry contact closure.
You can configure the Encompass 4 Reader to generate input status change reports,
which are transmitted like tag IDs. The host can then respond based on the true/false
(closed/open) status of the sense inputs. See the section “Reports” on page 8-13.
The following procedures describe how to set sense inputs using the terminal emulation software. See commands “526 Display I/O Status” on page 7-22, “694N Select
Input Inversion Option” on page 7-46, and “82N Select Input Status Change Report
Option” on page 7-50 for more information.
To set sense inputs
1. Ensure that the host computer is in command mode.
2.
Enter command #526 to display the current input/output status. C0 = host
controls outputs; C1= predefined output mode; O0 = both outputs off; O1 =
output0 on; O2 = output1 on; O3 = both outputs on; I0 = both inputs false; I1 =
input0 true; I2 = input1 true.
3.
Enter command #6940 to disable input inversion (factory default) or command
#6941 to enable input inversion, and press ENTER.
Sense Output Devices
Both the RS–232 and RS–422 configurations used by the Encompass 4 Reader have
two sense output circuits – sense output0 and sense output1.
By default, the Encompass 4 Reader operates in predefined output mode where sense
output0 and sense output1 are asserted every time a unique valid tag is read. Both
sense output devices are asserted by issuing command #621 Predefined Output Control. The devices are not asserted when tags are acquired in the transmit all or buffer
all ID mode or when the Encompass 4 Reader is operating in Wiegand mode. The
sense output pulse duration is variable (command #67N).
The host computer can disable the predefined sense output control by issuing com-
8-17
Encompass 4 Reader System Guide
mand #6201 to turn sense output0 on or by issuing any of the following commands:
#6200 Turn Off Both Output Ports, #6201 Turn Off Output0, On Output1, #6202
Turn Off Output1, On Output0, or #6203 Turn On Both Output Ports. While under
host control, the sense outputs are not automatically asserted when a valid tag is read.
The host must issue command #621 Predefined Output Mode to return to the predefined mode.
Serial Port Communications
The Encompass 4 Reader supports one communications port, which can be ordered as
either RS–232/Wiegand or RS–422/Wiegand. For the RS–232 and RS–422 communications specifications, the Encompass 4 Reader maintains the following three sets of
parameters that affect serial port communications:
•
Port configuration parameters (baud rate, data bits, stop bits, parity)
•
Communications protocols (basic, error correcting)
•
Flow control scheme (none, software, hardware)
The default serial port configuration for each of these three parameters is as follows:
•
9600 baud, 8 data bits, 1 stop bit, no parity
•
Basic communications protocol
•
Software flow control (XON/XOFF)
You can change these parameters in data mode and command mode operation by issuing commands with the host computer. Use the following procedures to set serial port
communications parameters using the terminal emulation program.
Port Configuration Parameters
Use this procedure to set port configuration parameters using the terminal emulation
program. Consult sections “100N Select Baud Rate" through “102N Select Parity” on
page 7-7.
To set baud rate
1. Ensure that the host computer is in command mode.
2.
Enter command #100N and press ENTER.
To set stop bits
1. Ensure that the host computer is in command mode.
2.
Enter command #101N and press ENTER.
To set parity
1. Ensure that the host computer is in command mode.
2.
8-18
Enter command #102N and press ENTER.
Configuring the Encompass 4 Reader
Communications Protocol
Use the following procedures to set communications protocol. Consult sections “610
Select Basic Communication Protocol (Factory Default)" through “612NN Select
Error Correcting Protocol Timeout” on page 7-31 for more information.
Caution
Do not switch to ECP (command #611) unless the host is prepared to acknowledge
each reader transmission.
To select a communications protocol
1. Ensure that the host computer is in command mode.
2.
Enter command #610 to select basic protocol (factory default) or command
#611 to select ECP and press ENTER.
Software Flow Control
Two modes of flow control are supported — software (XON/XOFF) and hardware
(CTS - clear to send). The host can enable or disable flow control with command
#614N Select Flow Control Option.
The host can use software control characters (XON/XOFF) or the hardware CTS
handshake line to interrupt reader transmissions. When the reader is configured for
software flow control, it stops transmitting if it receives the XOFF character from the
host (host software command 13H). It resumes transmitting only when it receives the
XON character (host software command 11H) from the host. Likewise, when the
reader is configured for hardware flow control, it stops transmitting if it detects that
the CTS line is no longer asserted. It resumes transmitting when this line is asserted. If
flow control is not needed, the reader should be configured for no flow control
(#6140 Disable Flow Control).
Note: TransCore recommends that XON/XOFF flow control be disabled while using
the error correcting protocol.
Use the following procedure to set flow control parameters using the terminal emulation program. See section “614N Select Flow Control Option” on page 7-32.
To select flow control
1. Ensure that the host computer is in command mode.
2.
Enter command #6140 to disable flow control, command #6141 to enable
software flow control (factory default), or command #6142 to enable hardware
flow control and press ENTER.
Fine-Tuning and Verifying the Read Zone
If the read zone is too wide or too deep for your application, it can be fine-tuned by
8-19
Encompass 4 Reader System Guide
physically adjusting the Encompass 4 Reader or external antenna mounting orientation, reprogramming the actual RF power output (#644NN Set RF Attenuation), and/
or reprogramming the RF sensitivity range (#643NN Set ATA Operating Range and
#645NN Set eGo and eGo Plus Operating Range). The combination of these adjustments allows you to confine the read zone to the area where tagged vehicles pass. This
operation also minimizes reading unwanted vehicles in adjacent lanes or parking
areas.
See sections “643NN Select ATA Operating Range (Distance)” on page 7-38, “645NN
Set eGo and eGo Plus Operating Range (Distance)” on page 7-38, and “644NN Set RF
Attenuation” on page 7-38 for more information.
Note: As described in “Marking the Read Zone” on page 4-38, marking the read pattern using test tags that are not mounted to vehicles give a general idea of the read
pattern but the pattern will vary somewhat when actual vehicles with tags are tested.
Final adjustments must be made with tags properly mounted on a variety of vehicles.
Physically Orienting the Encompass 4 Reader
You can manually adjust the location of the read zone by loosening the Encompass 4
Reader mounting brackets and pointing the reader in the desired direction. The unit
should be aligned to point directly at the tag as it enters the desired read zone.
Physically Orienting the Encompass 4 Reader Antenna
You can manually adjust the location of the read zone by loosening the antenna
mounting brackets and pointing the antenna in the desired direction. The unit should
be aligned to point directly at the tag as it enters the desired read zone.
Fine-Tuning the Read Zone by Lowering Output Power
You can make the read zone smaller by adjusting the Encompass 4 Reader RF power
output from a maximum of 2 watts to a minimum of 200 milliwatts using command
#644NN Set RF Attenuation. Lowering the RF power has the added benefit of reducing RF interference with adjacent lanes.
To adjust the read zone by lowering output power
1. Ensure that your PC is communicating with the Encompass 4 Reader using a
terminal emulation program as described in section “Verifying Communications”
on page 8-8.
2.
Mark the current read zone as described in section “Marking the Read Zone” on
page 4-38.
Caution
Test tags should be compatible with your Encompass 4 Reader. Test tags can be
ATA-protocol, ISO-compliant, or Inter-Agency Group tags affixed to a plastic or
wooden yardstick, or eGo or eGo Plus sticker-type tags affixed to a piece of nonmetallic windshield-type glass 0.190 to 0.230 in (4.82 to 5.84 mm) in thickness. The
sticker-type tags have a reduced read range when not attached to glass.

Configuring the Encompass 4 Reader
3.
Enter command #01 to switch to command mode. You are prompted with
#DONE from the reader and can now enter reader commands.
4.
Enter in command #64401 to lower the RF power by 1 dB below 2 watts
(default). Press ENTER.
Note: In the command #644NN, NN can be any hexadecimal value from 00 to
0A. Settings for attenuation are 1.0 dB increments over a range of 10 dB of attenuation from the maximum power setting of 2 watts at 0 dB attenuation to a minimum power level of 200 milliwatts at 10 dB attenuation. Increasing the
attenuation lowers the output RF power.
5.
Switch to data mode by entering command #00 and pressing ENTER.
6.
Verify that the read zone has decreased by moving the tag through the desired
read area. If the read zone is still too large, switch to command mode and enter
the command #64402 to lower the output RF power another 1 dB. Continue
increasing the NN value until the read zone matches the desired read zone.
7.
Follow the steps in “Procedures” on page 4-39 to mark the new read zone on the
ground with tape or chalk.
When the desired read zone is established, test the read zone with simulated and
real traffic by performing the following procedures:
To test the read zone
1. Ensure that the Encompass 4 Reader is in data mode.
2.
With the Encompass 4 Reader running, place one tag behind your back while you
hold another tag in the new read zone. If a valid read, the data from the tag held in
the read zone displays on the PC screen.
3.
Switch tags, placing the other tag behind your back and holding the first tag in
the read zone. If a valid read, the data from this tag held in the read zone displays
on the PC screen. If both tags are read, you have successfully adjusted the read
range.
4.
If one or both tags did not read, follow the suggestions in “Verifying Tag Read
Capability” on page 8-10.
5.
As a last test, attach test tags to vehicles and simulate traffic going through the
read zone to verify that the system performs accurately in a live environment.
Fine-tuning the Read Zone by Adjusting Sensitivity Range
The Encompass 4 Reader read zone can be fine-tuned by using command #643NN
for ATA tag read mode or #645NN for eGo and eGo Plus tag read mode to reprogram
the RF sensitivity range. Sensitivity range adjustments have less impact on the read
pattern than RF power adjustment, thus RF power adjustment should be used as the
main read pattern adjustment tool. Sensitivity range control may be helpful in stopping some tag reads on the very edges of the read pattern. To produce a noticeable
change in the read pattern, you must decrease the range sensitivity by more than one
increment.
8-21
Encompass 4 Reader System Guide
To adjust the read zone by adjusting sensitivity range
1. Ensure that your PC is communicating with the Encompass 4 Reader using a
terminal emulation program as described in “Verifying Communications” on
page 8-8.
2.
Mark the current read zone as described in “Marking the Read Zone” on page 438.
3.
Enter command #01 to switch to command mode. You are prompted with
#DONE from the reader and can now enter reader commands.
4.
Enter command #64318 or #64518 to decrease the range sensitivity seven
increments below the maximum (default). Press ENTER.
Note: In the command #643NN or #645NN, NN can be any hexadecimal
value from 00 to 1F. The reader’s receiver becomes less sensitive to tag signals as
the value of NN is lowered from the maximum sensitivity of 1F to the minimum
sensitivity of 00.
5.
Verify that the read zone has decreased by moving the tag through the desired
read area. If the read zone is still too large, switch to command mode and enter
the command #64317 or #64517 to decrease the range another increment.
Continue increasing the NN value until the read zone matches the desired read
zone.
6.
Follow the steps in section “Procedures” on page 4-39 to mark the new read zone
on the ground with the tape or chalk.
When the desired read zone is established, test the read zone with simulated and
real traffic by performing the following procedures.
To test the read zone
1. Ensure that the Encompass 4 Reader is in data mode.
8-22
2.
With the Encompass 4 Reader running, place one tag behind your back while you
hold another tag in the new read zone. If a valid read, the data from the tag held in
the read zone displays on the PC screen.
3.
Switch tags, placing the other tag behind your back and holding the first tag in
the read zone. If a valid read, the data from this tag held in the read zone displays
on the PC screen.
4.
If both tags are read, you have successfully adjusted the read range. If one or both
tags did not read, follow the suggestions in “Verifying Tag Read Capability” on
page 8-10.

Symptom
When performing a quick
test of the Encompass 4
Reader, the buzz box does
not buzz.
Remedy
Check all your wiring connections and antenna connections (if
using external antenna), and ensure that your buzz box is
functioning.
The wires from the Encompass 4 Reader are grouped in pairs.
You could find more than one red wire, more than one black
wire, and so on. You must connect the correct red and white
wire pair to the leads from the battery.
Verify that RF is on as described in “Bench Testing the
Encompass 4 Reader Before Installation” on page 4-13. Using
a terminal emulation program, you may switch to command
mode and issue command #527 to determine RF status. See
page 7-24 for more information.

Symptom
Remedy
The baud rate is selected
correctly but nothing
happens.
The Encompass 4 Reader is not communicating with your PC.
Check the power supply to your PC, and check the
connections between the PC and the Encompass 4 Reader.
Try reversing the receive and transmit connections.
When testing the
Encompass 4 Reader, all the
wires are connected
correctly but the unit does
not respond.
The Encompass 4 Reader may not have the software loaded
inside the unit. Contact Technical Support as described on
page 9-7.
If you are using a terminal emulation program, check that the
terminal emulation setting on the Encompass 4 Reader is
VT100.
Check that the Encompass 4 communication cable is
connected to the correct COM port.
Verify that the external antenna is connected correctly.
Strange signal responses
come from the Encompass 4
Reader when tested with the
PC.
Ensure that the reader is in the correct interface mode for the
test tag, i.e., Wiegand mode for a Wiegand tag. If using
hyperterminal, Wiegand tag data may display as unintelligible
characters.
Check the system defaults using a terminal emulation
program. Both PC and reader should be set to 9600 baud, 8
bits, 1 stop bit, and no parity.
When a tag is moved in front
of the reader or external
antenna, a clicking sound
comes from the Encompass
4 Reader.
The Encompass 4 Reader works. The sound is the relay
inside the Encompass 4 Reader that is controlled by a lock
signal. The relay is actuated when a tag is in the read zone.
Nothing happens when the
test tag is passed in front of
the Encompass 4 Reader or
external antenna.
Ensure that the Encompass 4 Reader is powered on and is in
predefined output mode. (#621)
Verify that the reader is set to RF ON (#6401).
Verify that the external antenna is connected correctly.
Verify that the reader mode matches the test tag.
The Encompass 4 Reader
came from another site and
does not work the way the
factory defaults indicate that
it should.
Different commands were probably used to support the other
site’s specific configuration. You can restore the factory
defaults by using a terminal emulation program to switch to
command mode and issuing command #66F Load Default
Operating Parameters. All factory defaults except RF
frequency will be restored.

When connected to a PC
that is running terminal
communications software, a
just-powered up Encompass
4 Reader displays one of the
following messages: 
#Model E4 Series X.XX
SNYYYYYY
#[Copyright notice]
The Encompass 4 Reader works. The software is now loaded.
YYYYYY is the TransCore-assigned serial number for this

number has never been assigned. If a serial number has not
been assigned to your Encompass 4 Reader, contact
TransCore Technical Support.
The read zone is too small,
even before the RF power
and range control have been
adjusted.
If another Encompass 4 Reader is in the same area, ensure
that it is operating on another frequency that is at least 2 MHz
different.
Check for possible interference from another nearby RF
source: fluorescent lights, neon signs, high voltage power
lines, nearby cellular telephone, or radio stations. Lights will
need to be removed or shielded. Point the Encompass 4
Reader or external antenna in a different direction to see if
interference comes from only one direction. You may require a
different Encompass 4 Reader that uses another frequency.
Verify that the RF power is set to an appropriate value.
Verify that the range adjustment is set to the maximum.
Verify that the reader is getting at least 16V.

The perimeter of the read
zone has been defined, but
there is a “hollow” spot in the
center of the zone that does
not read tags.
The angle of the Encompass 4 Reader or external antenna
may need adjustment. Slightly tilt the Encompass 4 Reader or
external antenna to a different angle to change either the
length or width of the read zone.
The Encompass 4 Reader is
reading tags out of the
desired read zone, or crosslane reads are occurring.
Some interference from other RF or electrical sources may be
occurring. See “Reflection, Refraction, and Diffraction of RF
Signals” on page 2-16.
The Encompass 4 Reader is
not providing any output to
the Wiegand interface.
Ensure that the Encompass 4 Reader is in Wiegand mode
(#451). The default is either RS–232 or RS–422 mode. Refer
to “Wiegand Interface” on page 4-33.
Check the range control adjustment. See “Radio Frequency”
on page 8-15.
Verify that the read zone has been properly set up. See “FineTuning and Verifying the Read Zone” on page 8-19.

Command Quick Reference
This appendix lists the default configuration settings for the
Encompass® 4 Reader and its commands. Commands are listed both
numerically and alphabetically.
Command Syntax
The command numbers consist of from 2 to 4 hex digits. The letters N or S may follow
a command number. The letter N indicates that part of the command number is variable. The letter S indicates the requirement for an alphanumeric data string that is to
be included immediately following the command number. Hex digits (0–9, A–F) in
either uppercase or lowercase characters may be used in data strings and for hex digits
A–F. For more information see Chapter 5, “General Software Information.
Table D-1 lists factory default settings. Table D-2 on page D-5 lists, in numerical
order, all of the commands available to users. Table D-3 on page D-17 lists the same
commands by command name.

Tag Data Formats
Tags are programmed at the TransCore factory with the tag model number, date of
manufacture, and data format. Contact TransCore for special order entry procedures
for the format that applies to your system. The following four tag data formats can be
used:
•
10-character alphanumeric ASCII — Four alphanumeric characters are fixed and
can be used to identify either the dealer or the user. The remaining six positions
are numeric and should be unique for each tag issued. For example, the entry
ACME000001 might be specified as the first tag on the order entry form from
ACME Parking Garage.
•
20-character alphanumeric ASCII — Four alphanumeric characters are typically
fixed and the remaining 16 positions are numbered sequentially.
•
Wiegand — Tags can be programmed in Wiegand formats with 26 to 54 bits. If
you choose this format, complete a Wiegand format worksheet — attached to the
order entry form — indicating the data to be programmed into the tags.
Note: Security access control tag models can be Wiegand-formatted. SeeTable E-1
through Table E-3 for Wiegand-compatible tag models.
E-6
Compatible Tag Information
•
AAR/ISO — For requirements for this format, refer to ISO 10374 and the most
recent version of Association of American Railroads Standard for Automatic
Equipment Identification.
