Interface
RS485
NOTE!
A twisted connecting cable with shielding must be used to connect the RS485 interface. To avoid trans-
mission errors, only the signals listed above and, if necessary, GND may be routed in the connecting
cable.
To ensure fault-free operation, terminating resistors are required at the beginning and end of an RS485
transmission path.
