If enabled (checked), at startup, the scanner sends a message to recognize the presence of, and communicate with,
the Backup Module. If using the Backup Module, this parameter must be enabled (checked).

startup.
Data TX
If enabled (checked), data from the scanner will be transmitted on the Auxiliary Serial Port.

the Heartbeat message is not transmitted
Enable Unconditioned
the Heartbeat message is always transmitted, even if
