  • Page 17: Chapter 1 System Overview

    (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.

  • Page 18: Ai1422E Models

    Reader and RF module, combined in one unit Reader Power Regulation and Filtering The AI1422E Reader System uses an input voltage ranging from 24 VDC to 110 VDC (12 VDC to 150 VDC Min/Max). The reader system incorporates a high-performance, DC-to-DC power supply that converts voltage in this range to 24 VDC.
  • Page 19 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.

Note: If the !41 command was issued prior to this test, the PC will be receiving a continuous stream of tag data. If the !41 command was not issued, the reader responds with only one response.

  • Page 35: Chapter 5 Communications Protocols

    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.
  • Page 36 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.

  • Page 37: Chapter 6 Commands

    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.
