LF80C ZeniD RFID Reader 7 Operation
Product Manual 7.2 Operation of the ASC-I1 Protocol
H - Heartbeat The command H sends a heartbeat request to the reader. The reader
responds with his serial number and a response code.
The response code is part of the protocol but is not used for this device. The
response code is always '0000'.
Because of compatibility with other systems, the heartbeat is also allowed
with the address 'F'.
