The following must be observed: DIN 19245 Part 1
The potential difference between the data reference potentials M of all interfaces must not
exceed -7V / +12V. If this cannot be guaranteed, then equipotential bonding must be
provided.
Activate interface 3:
– Set the baud rate in parameter P803.
– Set the protocol in parameter P800.
