5.4.2 Answer On Request AOR Mode
The AOR feature is used to address an individual transponder, among others in a common field. For
AOR mode to function, transponders must be also be configured for password mode. Each transponder
has to be programmed with a unique password. If the reader sends an AOR wake-up sequence that
matches a password of one transponder present in the field, the transponder starts to transmit its ID
code continuously. The transponder remains active until a POR occurs or until a new command with a
different password is sent.
Note: For the AOR test procedure, it is recommended to designate all transponders with an individual password
number.
