mately 330Ω on the receiver for data free traffic.
The protocol 3964(R) is not possible at two-wire operation.

mately 330Ω on the receiver for data free traffic.
For a connection with minimum reflections and the wire-break recognition at RS422/485
operation, the lines may be preset with defined static voltage levels.
At the CP interface the wiring of the receiver is realized as follows:
