ARE I2 / RS 232 – Installation Guide

After entering a valid command together with a parameter value, the system answers by sending the parameter value and <CR>. Example:

Command:

MD <SP> 2 <CR>

Output:

2 <CR>

After entering an invalid parameter value, the system answers with the corresponding error code

Parameter settings can be queried by sending the command without adding an parameter value. Example:

Command:

MD <CR>

Output:

1 <CR>

If a single <CR> is input, the reader answers with a single <CR>. Example:

Command: <CR>

Output: <CR>

Please note: If echo mode is active, a single <CR> forces the reader to output <CR> <CR> (echo plus output).

6.2Error Codes

If a command is not entered correctly, the reader sends one of the following error codes:

Wrong command: <NAK> #00 <CR>

Wrong parameter: <NAK> #02 <CR>

6.3CID – Suppression of ID Codes

With CID=1 only the first of in succession identical transponder numbers is output on the serial interface. The possibly following identical transponder numbers are suppressed, as long as no new valid transponder number is received, processed and output. NoReads do not influence the data filtering.
