For communication via the back panel RS232 interface and the
setup interface, the device address must be observed, even
though it is not a bus interface!
The configuration of the setup interface cannot be edited,
but is fixed to
- Modbus slave,
- 9600 bps,
- 8-1-none,
- device address 1
The three serial interfaces can be operated simultaneously. There
are merely some interlocks built in at the protocol level (e.g. only
one setup can be written at a time).
