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 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
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
vi
TransCore Proprietary
AI1422E Reader
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.
TRANSCORE RECOMMENDATION ON MPE (MAXIMUM PERMISSIBLE EXPOSURE)
The calculated power densities and MPE distance for each of the agencies respective to the environment
is shown below.
With the equipment installed and running at the maximum transmit power of 2.0W (33dBm), 0 dB transmit
attenuation, using the highest gain antenna that the equipment is certified for, the recommendation for
each of the operation environments is as follows:
1)
The antenna should be installed at least 47in (120cm) from the General Population/Public i.e.
Uncontrolled Environment.
2)
Maintenance personnel (i.e. Occupational/Controlled Environment) must remain at least 18in
(45cm) from the antenna and limit their time in the environment to 6 minutes when the system

System Overview

System Overview
The AI1422E Reader System is a microprocessor-controlled, single-antenna unit that
uses a unique communications protocol to interface with vehicle identification (ID)
equipment.
This reader system uses radio frequency (RF) energy to read data from tags. The AI1422E
Reader System then decodes the tag ID information, validates the ID code, and transmits
tag data directly to a host processor for real-time data processing and use.
Communications (terminal) programs usually do not provide adequate data processing
capability. Your host computer software can be customized to provide the required
capabilities.
The AI1422E Reader System consists of the AI1422E Reader, which consists of a reader and
RF module, combined with a TransCore antenna, a TransCore tag, a host processor system,
and a power source. Figure 1 illustrates a typical reader system configuration.

TAG
AI1422E Reader
Transponder Interrogator
The transponder interrogator reads 60/120 bits of user-programmable data in the
transponder.
The transponder interrogator is operated in a continuous read mode, and any tag
entering its read field has its data automatically read and relayed to the host computer. In
many applications this function is implemented by installing the reader on a vehicle with
restricted movement, such as a railcar or monorail bus. The tags are embedded in the
roadway at various locations in the vehicle’s path. The data read from the tag allows the
host computer to assess the vehicle’s location and make any appropriate response to that
information.
The transponder interrogator is an independent tag decoder that combines a reader and
RF source to provide automatic identification and data storage within a single, compact
unit. The transponder interrogator includes the following components:
•
19-inch rack-mount design (1U)
•
RS232/RS422/Ethernet input/output (I/O) link
•
Real-time clock
•
Reader and RF module, combined in one unit
Reader Power Regulation and Filtering
The reader system uses an input voltage ranging from 24VDC to 110VDC (12VDC to
150VDC Min/Max). The AI1422E Reader System incorporates a high-performance, DC-toDC power supply that converts voltage in this range to 24VDC. This voltage conversion is
internal to the unit, and should be transparent to the end-user.
Antenna
TransCore has multiple antennas for use with the AI1422E Reader, covering multiple
applications such as heavy rail, light rail, European regions, and more. Contact TransCore
for assistance with antenna selection.
Tags (Transponders)
The AI1422E Reader System can use TransCore’s half-frame or full-frame read-only tags.
When selecting a tag for an application that requires the tag to be placed on the road bed,
several design elements need to be kept in mind.
Beam-powered tags have a shorter footprint than battery or switch-powered tags, and thus
the maximum top speed of the vehicle will be less, all other factors equal.
Battery tags have an inherently larger footprint, but the battery life limitation will require the
operating company to replace the tags every 8 to 10 years. The presence of the battery
and its reactive mass reduces the reliability of the tag, particularly when the tag is placed
near high shock or vibration locations such as switches.
Switch-powered tags have RF characteristics similar to battery tags, and the tags are
powered by inductive power derived from railway switch power.
TransCore Proprietary
User Guide
Tag Mounting
All tags used with the AI1422E must be mounted on a flat metal plate. The internal
antennas of these tags are tuned for the backplane of the tag to be in contact with a
flat metal surface. This metal surface does not need to be extended beyond the outer
dimensions of the tag, and having a larger metal surface will not affect the immediate
performance of the tag.
Metal located to the sides or above the tag can affect the tag’s performance. Metal
surfaces or objects should not be placed closer than 1 inch (2.5 cm) to the side edges
of the tag to ensure that the tag’s antenna tuning remains within design criteria. Metal
placed above the tag can cause shadowing of the RF beam, both in the incident and
return directions, and should be avoided. The only exception to this rule would be metal
placed for the purpose of affecting the read range of the tag or footprint of the system, and
the placement of such metal should be done with careful planning and testing to ensure
proper system performance. With battery-powered tags, the arrangement of intentional
metallic obstructions may be the best way to limit the broad footprint of these tags, as
well as improve the repeatability of the TLS signal with respect to its absolute position
relative to the tag. These tag mounting details would need to be made by the customer on
the basis of each customer’s overall system design and requirements. Keep in mind that
metal placed too close in proximity to the tag will affect the tag’s antenna tuning, and may
unintentionally affect principal design parameters such as VSWR or the impedance match
of single paths internal to the tag, to name a few examples.
Antenna-to-Tag Centerline Alignment
For best performance, mount tags so that the centerline of the tags and the centerline of
the reader antennas are within ±2.9 inches (±7.5 cm) of each other (Figure 2).
Antenna-to-tag Distance
Many installations have been installed with a nominal 11.8-inch (30-cm) distance from the
backplane of the reader antenna to the back edge of the tag (Figure 2).

Communications Protocols
User Guide
Communications Protocols
The AI1422E Reader supports the following communications protocols:
•
Basic
•
Error correcting protocol (ECP)
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 when
using ECP. This interchange is completed by the message recipient returning a message
acknowledgment 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 AI1422E 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 AI1422E Reader as the
XOFF character, which would suspend reader output without information reaching the host
computer. For more information refer to “525 Display Communications Protocol Status” on
page 40.
Note: TransCore recommends that XON/XOFF flow control be disabled while using ECP.
Basic Protocol
With basic protocol, messages sent to and from the AI1422E Reader and the host are
transmitted without error checking. For each host transmission, the AI1422E Reader returns
a Done or Error message to the host.
When the host computer is physically close to the AI1422E 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 AI1422E 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. Refer to “Command Codes” on page 25 for flow control
information.
22
TransCore Proprietary
AI1422E Reader
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 AI1422E 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
AI1422E 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 AI1422E Reader will issue an Error message, and the host computer will
issue a negative acknowledgment message.

Command Codes
AI1422E Reader
Command Codes
The AI1422E 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.
Note: If you are using Wiegand mode, you must connect the PC or laptop to the
AI1422E 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 AI1422E Reader has three modes of operation: Data Mode, Command Mode, and
Download Mode. The software for the AI1422E Reader contains two separate programs —
Boot and Application. The Boot program has control of the AI1422E Reader on startup and
when operating in download mode. The Application program has control of the AI1422E
Reader during a command mode operation and holds the application code. Together, they
control the AI1422E Reader in the three modes of operation.
Data Mode
The AI1422E Reader is in Data Mode on power-up. While in Data Mode, the AI1422E
Reader sends all communications to the host computer as data messages, such as tag IDs
and reports. Reports provide information on Input 0 and Input 1 status changes, a presence
without tag report, and buffer overflow information. The host computer can send only four
commands to the AI1422E Reader while in Data Mode (Table 1).

AI1422E Reader
Command Mode
While the AI1422E Reader is in Command Mode, the host computer sends commands to
the AI1422E Reader that can be used to control the operation and configuration of the
reader. After the AI1422E 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.
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 AI1422E Reader properly receives the
request and transmits the Done message, one of the two following conditions may occur:
1.
If the host computer receives the Done message, then both the host and the AI1422E
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. The AI1422E Reader changes the baud rate immediately after
issuing the Done message.
2. if the host does not receive the Done message transmitted by the AI1422E 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 AI1422E 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 AI1422E Reader turns RF off, does not process 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
TransCore Proprietary
31
User Guide
“Command Quick Reference” on page 80 for listings of commands in both numerical
and alphabetical order.
In the Command Quick Reference list, 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
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.
00/662 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.
The command !662 is present for backward compatibility with
previous generation AI1422 readers, and is not recommended for use.
Caution
To save user parameter changes to NVRAM, you must send command
!00/!662 before powering down the reader.

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 12.
Each time the reader receives a tag ID, it compares the ID with the
contents of a comparison register. This register contains the following
four 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 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.

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 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

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

Command !442
Command !443

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).

612NN Select Error Correcting Protocol Timeout
Command !612
NN selects the timeout interval for ECP. This timeout applies to the
transmission of tag, report, and error messages and to the receipt of
host commands. The transmit timeout is initiated immediately after the
end-of-message sequence CR/ LF is transmitted. If the host does not
acknowledge the message within the specified interval, the reader
times out and retransmits the message.
The receive timeout is initiated upon receipt of the start-of-message
character (!). If the end-of-message character (CR) is not received
within the specified interval, the reader discards the partially received
message and resets its receiver.
Uppercase or lowercase characters are allowed for NN; for example,
hex digits A through F or a through f.
The value for NN specifies the timeout interval as follows:

647XXX Select RF Operating Frequency (Used only for FCC Part 90 Units)
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.
Note: Frequency doesn’t have a factory default and must be
programmed by the end user.

Command !697
assigns the user-programmable GSE filter.
The command string is assigned according to the following format:
697 MM AA DDDDDDDDDDDDDDDD
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

Troubleshooting and
Maintenance
AI1422E Reader
This section lists routine diagnostic procedures for troubleshooting an improperly working
reader system and maintenance procedures to keep the AI1422E Reader System operating
correctly.
Required Tools and Equipment
The following tools and equipment are required:
•
50-ohm, 5-watt (W) load (N-type connector)
•
Personal computer (PC) with terminal emulator software
•
Appropriate power source for your reader
•
Digital multimeter
•
Loopback DE09 Connector
•
Antenna and cable
•
Slot head screwdriver
Troubleshooting
Loopback Mode
It is possible to reset the AI1422E Reader to default by looping back the TX from the RS232
into the RX via a short wire. Installing a loopback will cause the reader to reset its settings
to factory default, which is extremely useful during troubleshooting. The procedure for
resetting the reader is below.
1.
Power down the AI1422E reader by toggling the main power switch to the OFF position.
2. Slide the Interface Selection switch on the front panel of the reader to RS232.
3. Install a loopback connector to the MAIN RS232 port.
4. Apply power to the AI1422E reader by toggling the main power switch to the ON
position.
5. Wait 30 seconds for the reader to complete the factory reset.
6. Power down the AI1422E reader by toggling the main power switch to the OFF position.
7.
The reader should now be configured for factory default settings.

Failure Modes
No Communication
To determine if there is a problem in the communications hardware, the following two
commands should be repeated together for testing purposes:
!01
!22
escape to diagnostic mode
display time and date
If functioning properly, the time and date will be displayed after the second command,
which means that the reader is communicating. If the reader is not functioning properly,
then perform the following checks.
•
Verify that the AI1422E Reader System has adequate power. It should have
24V DC ±0.5V DC.
•
Verify that the main power switch is on.
•
Verify that the main power light-emitting diode (LED) is illuminated.
•
Verify that you are using a null modem cable connection.
•
Verify that the Interface Selection switch on the front panel of the reader is set to the
correct interface.
•
Verify that the baud rate is set correctly. If an incorrect baud rate is suspected, select
and send each baud rate in turn, using the !100x Baud Rate Select command, and wait
for a response.
Unit Will Not Read Tags
The suggestions listed here assume that the user has already verified proper serial
communications. If RF POWER LED is illuminated, the indication is that the AI1422E is
querying for tags. If the LOCK LED is illuminated, the indication is that the reader system
is retrieving tag data. If neither of the LED indicators are illuminated, check the following
items:
•
Verify that the antenna connection is good.
•
Verify that the antenna cable is in good condition.
•
Verify that a single, known valid tag, properly polarized, is in the antenna field.
•
Verify that the trigger remains activated and the unit power is on.
•
Verify that a tag is being alternated with another tag containing different data to avoid
uniqueness filtering.
Unit Will Not Retain Settings
If the unit will not retain information, such as time and date stamp or baud rate between
power cycles, the internal battery backup has failed and the unit must be returned for
repair. Contact TransCore technical support.
