RADIO FREQUENCY HEALTH LIMITS FOR AI1422 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 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)

TransCore Proprietary
AI1422E Reader
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
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.

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 2 – 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 imbedded 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 12VDC to 150V DC. The AI1422E
Reader System incorporates a high-performance, DC-to-DC 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.

Transponders (Tags)
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. The beam powered tags will have a
shorter footprint than a battery or switch powered tag, and thus the maximum top speed
of the vehicle will be less, all other factors equal. However, although the battery tag has
an inherently longer footprint, the battery life limitation will require the operating company
to replace the tags every 8 to 10 years. Additionally, 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.
For practical purposes, the switch powered tags have RF characteristics similar to battery
tags, and the tags are powered by inductive power derived from railway switch power.
Tag Mounting
All of the 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 in the immediate vicinity of the tag, that is, to the sides of the tag 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 effecting 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 – 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 – 2).

Communications Protocols
User Guide
Communications Protocols
The AI1422E 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 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 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 7-17.
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 7-2 for flow control
information.
6-2
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.
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 AI1422E Reader acquires tags, it buffers them but does not transmit them. Instead,
the host must poll the AI1422E Reader for each tag by sending a CTRL-E character (hex 5
digit). The AI1422E 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. AI1422E 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

Command Codes
This chapter discusses the host-transmitted commands that are used to control the AI1422E Reader
configuration and operation.
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 data mode and 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 the data mode upon power-up. While in the data mode, the
AI1422E 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 AI1422E Reader while in data mode:
•
Command !01 Switch To Command Mode changes the AI1422E Reader from the
data mode to the command mode. Refer to “01/~~CC Switch to Command Mode” on
page 7-4
Note: The AI1422E Reader transmits ID codes to the host computer when the
AI1422E Reader is in data mode. If the AI1422E Reader remains in the command
mode with tags passing through the read zone, all tag IDs are not reported.
Command Mode
While the AI1422E Reader is in the 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.

TransCore Proprietary
AI1422E Reader
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:
•
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.
Note: The AI1422E Reader changes the baud rate immediately after issuing the
Done message.
•
However, 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
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.
00/662 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.
While operating in data mode, the reader accepts the following commands:

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 first three
and the first four items, respectively.
Note: A new ID can fail the filter test and not be transmitted; however, it remains
7-10
TransCore Proprietary
AI1422E Reader
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

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 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).
Command Timeout Clock
!441 2 minutes (factory setting)
!442 15 seconds
!443 30 seconds
TransCore Proprietary

User Guide
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).

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. 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.

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).

to factory default, which is extremely useful during troubleshooting. The procedure for
resetting the reader is below.
13. Power down the AI1422E reader by switching the main power switch to the ‘OFF’
position.
14. Slide the Interface Selection switch on the front panel of the reader to RS232.
15. Install a loopback connector to the MAIN RS232 port.
16. Apply power to the AI1422E reader by switching the main power switch to the ‘ON’
position.
17. Wait 30 seconds for the reader to complete the factory reset.
18. Power down the AI1422E reader by switching the main power switch to the ‘OFF’
position.
The reader should now be configured for factory default settings.

Failure Modes
No Communication – To determine if there is a problem in the communications hard- ware,
the following two commands should be repeated together for testing purposes:
!01
escape to diagnostic mode
!22
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 prop- erly,
then perform the following checks.
•
Does the AI1422E Reader System have adequate power? If not, ensure reader has
24V DC ±0.5V DC.
•
Is the main power switch on? If not, switch it on.
•
Is the main power switch light-emitting diode (LED) lit? If not, turn on power switch.
•
Are you using a null modem cable connection? If not, switch to a null modem
connection.
•
Is the Interface Selection switch on the front panel of the reader set to the correct
interface? If not, slide the switch to the correct interface.
•
Have you set the correct baud rate? 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 lit, the indication is that the AI1422E is querying for
tags. If the LOCK LED, , is lit, the indication is that the reader system is retrieving tag data. If
either LED is not lit, then 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 being alternated with a 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 at the telephone number listed at the front of this user guide

state prior to losing lock (enabled/
disabled). Error08 will only be
issued after Error07 has been
issued.
No action necessary; the previous error has
been corrected.
Error11
The operator is attempting to use
an Intellitag-based tag in Wiegand
mode while the AI1422E Reader
is in ID-only mode, thus Wiegand
compatibility issues.
Enable eATA mode using command #489 if
Wiegand operation is needed and the tags
are programmed with Wiegand data.
