ASCII Protocol - Reference Guide May ’00 Product Description This is a simple protocol that you can use to send ASCII character commands to the reader. It is possible to use a standard terminal emulator program to send ASCII commands. The ASCII protocol can only be used with RS232 or RS422. 1.1.1 Microcomputer Reset TIRIS readers and control modules are equipped with a reset circuit which resets... -

May ’00 Chapter 1. Introduction Data Handling 1.3.1 Data Check A data check is always performed on the data signal received from the transponder. Three different reading status are possible when attempting to read a transponder: - Identification correctly received - Invalid Identification - No Identification detected (no read) After addressing MPTs, however, the TIRIS reader sends out different protocols as... -
