6.3.6 Command 43- Read Device ID
This command returns identification information relating to the device. The conformity
level of this command is level 01, basic identification (stream access only). As with most
of the other diagnostic commands, identical information is returned for any device ID that
the Base Radio is controlling (including Transmitters mapped to virtual device IDs when
operating in the device ID mapping mode).
For further details on this command, please consult the Modbus protocol specification.
6.4 Base Radio Holding Registers
The following are the Base Radio holding registers for all mapping modes (i.e. Device ID
and Register mapping modes). The values for each address are listed later in this
section.
Note Use this table for RF IDs 1 through 50 and for backwards compatibility.
