RS485 interface

The RS485 interface is designed with the UMG 96RM
as a 2-pole plug contact and communicates via the
Modbus RTU protocol (also see programming para-
meters).

Terminating resistors

The cable is terminated with resistors (120 ohm 1/4 W)
at the beginning and end of a segment.

The UMG 96RM has no terminating resistors.

Terminal block in the switch cabinet.
