2 System Overview
User Guide 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.
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.
User Guide 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.

6 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.
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.
7 Command Codes
User Guide 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.
AI1422E Reader Communications can be lost if the host computer attempts to send certain commands under marginal communications conditions.
User Guide 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.

AI1422E Reader 21 Set Date Command !21 sets the date. Enter the date in the proper format: two-digit decimal entries with no spaces between characters and using forward slashes “/” as delimiters. The entry format is as follows: 21MM/DD/YY where MM represents the month (01 to 12). DD represents the day (01 to 31). YY represents the last two digits of the year (00 to 99). - is the date delimiter.
User Guide error messages, presence without tag reports, and input status change reports. The factory default setting is time and date appended (command !302). The reader returns an Error message if its tag buffer contains data. The reset reader command !63 may be transmitted to clear the buffer; however, tag ID data will not be reported. If this is unacceptable, allow the buffer to empty before re-issuing append time and date command !30N. Append Time and Date commands are shown in Table 7 – 4.

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.
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.
