UMG 512

RS485 interface

In the UMG 512, the RS485 interface is designed as a
3-pin plug contact, which communicates via the Modbus
RTU protocol.

Termination resistors

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

Termination within the device is possible via the S1 DIP
switch of the UMG 512.

Terminal strip in the cabinet.
