Note line termination:
The RS 485 bus must be terminated with a characteristic impedance. To do this, the switch in
the bus connector must be switched ”ON” in the ”first” and ”last” bus users. The switch may not
be ”ON” in any of the other bus users. A detailed description and notes on cable laying and bus
cable laying can be found in the Manual Decentral Peripheral System ET200.
