3.3 Instructions for reading settings
3.3.1 CID – suppression of ID Codes
In the MD0 mode 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. The get tag command is not
influenced by this command. NoReads do not influence the data filtering. The leds are not influenced
by this command.
Input format: CID <SP> parameter <CR>
Output (example): 0 <CR>
Parameter:
PARAMETER FUNCTION
0 No suppression
1 Suppression of equal transponder numbers
Example: A, B, C are different transponder codes, N is NoRead error code:
