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 0.1-hour 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 7.7 in (19.5 cm).
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 13.9 in (35.4 cm) for the Occupational/ Controlled environment, and 31.1 in (79.1 cm) 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 maximum permissible exposure for general population/uncontrolled exposure at 915 MHz is 8.77 W/m2. The average time is 6 minutes. The maximum permissible exposure (MPE) is the following:

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 19,5 cm (7,7 po).

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 8,77 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 39,5 cm (15,6 po) pour l'environnement professionnel/contrôlé et de 66 cm (26 po) pour le grand public/ environnement non contrôlé.

Chapter 1 Introduction
Chapter1Introduction
System Guide Organization
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 where the information does not warrant a separate section, the addition of "...or antenna" distinguishes between the Encompass 4 Reader models.
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 Micro Mini Sticker Tag. The Encompass 4 Reader System also supports legacy transportation applications such as 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 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 reader logic board (also called a tag decoder), a radio frequency (RF) transmitter/receiver (called the RF module), and a patch antenna.
Note: A dedicated electrical power supply must be present at the site and available to the Encompass 4 Reader at all times. Refer to "Electrical Power" on page 2­16.
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. Figure1 shows the front and side views of an Encompass 4 Reader System.

Tags
The Encompass 4 Reader System has the capability to read TransCore SeGo, ATA and IAG protocol tags, and ISO-compliant read-only full- and half-frame tags. The reader can be ordered with up to two protocols enabled.
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 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
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. 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.

Chapter 1 Introduction
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. The user is responsible for filing the FCC license application before use. It can take up to two months before the application is granted. The TransCore dealer will provide assistance and support as necessary.
Registration
New users will need to register with the Commission Registration System (CORES). Registration will enable the user to:
· Receive and manage a 10-digit FCC Registration number (FRN) · View financial status with the FCC and make payments Online filing is available to submit the application and related technical drawings. Visit the FCC Universal Licensing System (ULS) webpage at https://www.fcc.gov/wireless/systems-utilities/ universal-licensing-system.
Application and License
Application and license status can be searched from the ULS home page. Readers must be installed and in use within a year of the license grant. If the FCC is not notified that the readers are active, the license will be automatically deleted. An FCC license typically has a 10-year term. Licenses should be renewed 90 days or less before the expiration date. For further information on obtaining a license from the FCC, contact TransCore technical support. Note: The FCC continually updates and improves the web interface for online license applications. This information in this section is subject to change.

Chapter2Developing the Site Plan
This chapter discusses site plan development for installing the Encompass® 4 Reader System.
Overview
Note: In this section, unless specifically stated, "Encompass 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: · Reading of mixed population tags · Reader, tag, and antenna alignment · Antenna selection · Site layout, mounting requirements, and traffic flow · Electrical and communication 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, and Inter-Agency Group (IAG) tags. Note: The Encompass 4 Reader can read ATA or ISO read-only tags in the presence of Intellitagbased tags, however, it is not recommended to read an Intellitag-based tag in the presence of an ATA or ISO read-only tag. Doing so 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 beampowered.

Chapter 2 Developing the Site Plan
Reader, Tag, and Antenna Alignment
The position of the Encompass 4 Reader, antenna, 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, and tag 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.

TransCore Proprietary

Encompass 4 Reader System Guide
Polarization
The polarization of the tag must be aligned in the same direction as the Encompass 4 Reader, as shown in Figure2. Note: Matching the tag and antenna polarization is critical to obtain optimal system performance.

Figure2Tag and Reader Orientation
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. Figure3 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.

Chapter 2 Developing the Site Plan
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 exteriortype tags on the exterior of the vehicle. Refer to "Chapter3 Choosing, Installing, Removing Tags" on page 3­20 for more detailed information on tag positioning.
Antenna Selection
This section contains guidelines that assist in antenna selection for an Encompass 4 Reader installation that uses an external antenna. The following antennas are compatible with the Encompass 4 Reader installation.
AA3100 Yagi (without radome)
Appropriate for installations with the following requirements and conditions: · 902 to 928 MHz operation · Non-icing environments · Relatively symmetrical reading range · Antenna profile not a major consideration

Site Layout, Mounting Requirements, 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:
· 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

Chapter 2 Developing the Site Plan

· RF output attenuation
· Range discrimination setting
· 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, refer to "Fine-Tuning and Verifying the Read Zone" on page 8­145.

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.
Table1 shows examples of staggered reader frequencies in a site with up to 14 readers.

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 as shielding, absorbing, range sensitivity adjustment, or barriers can also be used. Refer to "Chapter9 Troubleshooting and Maintenance" on page 9­149 for more information.

Chapter 2 Developing the Site Plan

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. Refer to "Other Encompass 4 Readers in the Area" on page 2­11. Strong RF sources of any frequency, in proximity to the tag, can preclude the tag receiving the reader interrogation. Refer to "Chapter9 Troubleshooting and Maintenance" on page 9­149 for more information.
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 "Figure29 Correct Orientation of Reader" on page 4-41.

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. Table2 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. Table3 contains power supply current requirements.

Power Extension
Use Table4 to determine the correct cable size according to the American Wire Gauge (AWG) standard for the necessary length of extension cable. The numbers in the first row of the table indicate cable size for the approximate cable length.
Note: If the cable is close to the maximum length, measure voltage at the Encompass 4 Reader with RF ON to ensure voltage does not drop below 16V. A drop in voltage below 16V causes a reduction in read range and possible damage to internal electronics as well as unreliable operation.

RS­232 Interface

Use an RS­232 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 RS­232 distance, such as fiber optic modems, have been selected.

TransCore Proprietary

2­17

Encompass 4 Reader System Guide

The standard RS­232 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 (yellow of the black/yellow pair), and a twisted pair for red (TxD) 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 single-point earth ground on the controller end of the cable.
RS­422 Interface
Use an RS­422 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 RS­422 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-signalground interface. The reader uses the Wiegand interface included with the RS­232 or RS­422 option.
Note: The Encompass 4 Reader comes from the factory with either RS­232 and Wiegand or RS­ 422 and Wiegand. If you want to use Wiegand, you must first connect the Encompass 4 Reader using the RS­232 or RS­422 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 Wiegandcompatible reader.
Note: When extending the Wiegand interface, use a three-pair cable such as Belden 2919. Use a twisted pair for the red (Data1) with ground (black of the black/yellow pair), and a twisted pair for blue (Data0) 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.
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 non-inductive 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.
