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

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)

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 is operating.

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.

Figure 1 Typical Reader System Conﬁguration

TransCore Proprietary 2

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

AI1422E Reader

• 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.

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 aect the immediate performance of the tag.

Metal located to the sides or above the tag can aect 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 aecting 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 aect the tag’s antenna tuning, and may unintentionally aect 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 eect 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.

TransCore Proprietary 22

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.

TransCore Proprietary

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.

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.

AI1422E Reader

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 o, does not process tags, and does not echo host commands.

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 dierent from the ﬁrst item. Separation of two IDs allows transmission if the new ID is dierent from Items 1 and 2 in the comparison register.

Separation of three and four IDs transmit the new ID only if it is dierent 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 buered, 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.

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 13). The factory setting is one acquisition (N = 0).

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.

AI1422E Reader

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.

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 eectively expires the timeout clock, which erases all current IDs in the comparison register. In eect, 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).

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

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:

ms 50 * NN for NN = 01 to FE (1–254)

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.

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 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 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 dierent data to avoid

uniqueness ﬁltering.

Table 27 Error Messages

Error Message Description Corrective Action

AI1422E Reader

Error06 NVRAM parameters have been lost.

The AI1422E Reader will not function properly because the RF section is shut o until the frequency is reset.

Error07 The RF phase locked loop (PLL) has

lost lock and is unable to operate at its intended frequency. RF output is disabled while the AI1422E Reader attempts to reset the PLL.

Error08 The RF PLL has successfully

regained lock and has been reset to its proper operating frequency. The RF section is returned to its state prior to losing lock (enabled/ disabled). Error08 will only be issued after Error07 has been issued.

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.

ErrorRF1 Warning message that the RF

board did not return an update acknowledge signal

Reset the frequency using command

#647XXX

Reset the RF frequency. Refer to “Radio Frequency” on page 8-15 for instructions.

No action necessary; the previous error has been corrected.

Enable eATA mode using command #489 if Wiegand operation is needed and the tags are programmed with Wiegand data.

If the reader indicates a single ErrorRF1 event and recovers from the error, no corrective action is required. You may want to track this error message if it should occur again. If the reader indicates repeated ErrorRF1 warning messages then return the reader to the factory.
