1System Overview
User GuideTransCore Proprietary 2System OverviewThe 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.Power SourceAI1422EHost Processor SystemRS232RS422EthernetAntennaTAGFigure 1 Typical Reader System Configuration
AI1422E ReaderTransCore Proprietary 3Transponder InterrogatorThe 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 unitReader Power Regulation and FilteringThe 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-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.AntennaTransCore 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 GuideTransCore Proprietary 4Tag MountingAll 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 AlignmentFor 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 DistanceMany 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).Figure 2 Antenna-to-Tag Centerline Tolerance

Each time, the lock LED should be illuminated and the PC should be reporting the tag data.
5Communications Protocols
User GuideTransCore Proprietary 22Communications ProtocolsThe 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 ProtocolWith 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.
AI1422E ReaderTransCore Proprietary 23Error Correcting ProtocolWhen 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.
6Command Codes
AI1422E ReaderTransCore Proprietary 25Command CodesThe 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 ModesThe 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 ModeThe 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 buer overflow information. The host computer can send only four commands to the AI1422E Reader while in Data Mode (Table 1).

AI1422E ReaderTransCore Proprietary 31Command ModeWhile 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.CautionThe host computer should not attempt to change communications parameters or protocols during marginal communications conditions; otherwise, a loss of communications can result.Download ModeIn 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.Command ListReader commands are divided into groups based on primary function. The following sections provide information about each command in command number order. Refer to
User GuideTransCore Proprietary 32“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 ControlGroup 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.CautionTo save user parameter changes to NVRAM, you must send command !00/!662 before powering down the reader.Switch to Command ModeWhile operating in Data Mode, the reader accepts the following commands:Command !01 Switch to Command ModeReader response: No ResponseCommand ~~CC switches the reader to Command Mode, which allows the reader to accept commands from a host or terminal.

User GuideTransCore Proprietary 3841 Transmit All ID CodesCommand !41 instructs the reader to transmit all IDs without regard for uniqueness. This command can be useful when mapping the footprint or per forming diagnostics.After diagnostics are complete, you may want to reinstate the uniqueness check using command !410N Select Unique ID Code Criteria, or by using !40 to set reader back to its original setting.Reader response: Done410N Select Unique ID Code Criteria (Anti-passback Feature) Command !410N instructs the reader to buer 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 IDItem 2 Second-most recently acquired ID Item 3 Third-most recently acquired ID Item 4 Fourth-most recently acquired IDWhen 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.Reader response: Done
AI1422E ReaderTransCore Proprietary 39Table 12 Unique ID Code Criteria420N Select Valid ID Code CriteriaCommand !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.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.Table 13 Select Valid Code Commands and FramesCommand Uniqueness Criteria4100 Separation of 1 ID (factory default)4101 Separation of 2 IDs4102 Separation of 3 IDs4103 Separation of 4 IDsCommand Valid Code Frames4200 1 (Factory default)4201 24202 34203 4

It is used in conjunction with the Variable Timeout (!44N) commands. This command provides a method to end all uniqueness timers.44N Set Uniqueness TimeoutPlaces 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 ClockCommand !441 2 minutes (factory setting)Command !442 15 secondsCommand !443 30 secondsEntering 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).450 Disable Wiegand Mode (Factory Default)Command !450 is a default set in the factory to disable Wiegand mode.

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.
User GuideTransCore Proprietary 72Failure ModesNo CommunicationTo 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 dateIf 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 TagsThe 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.Unit Will Not Retain SettingsIf 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.
