Operation of the CA1 module is also dependent on parameters received on RS485 communication
channel.
Reader RFID field is active always when module is powered up. If tag is put inside RFID field, reader
tries to resolve RFID tag code. If code is read successfully, module activates status iIDNew,
generates a short beep, OK LED1 blinks and code is transmitted in iIDW1 - iIDW3 status fields. In
MCU application this code can be read out and authenticated. If code has appropriate rights, MCU
should activate oOK command. If code is not authorized, MCU application should activate oFault
command. Regarding command received, following action are triggered on module:
