Maschinenfabrik Reinhausen GmbH 2022
Data cable
The device is connected via the RS485 interface (COM2) via the CPU as-
sembly module (X4) or PCB connector (see Technical data).
1. Connect the RS485 interface COM-X1 on the interface module and the in-
terface CPU-X4 together using the patch cable.
2. Connect the wires of the shielded cable in accordance with the connection
diagram.
3. Position the cable shielding, screw it into the shield clamp provided, and
provide strain relief (using a cable tie).
Data cable
The device is connected via the RS232 interface (COM2) via the CPU as-
sembly module (X5) or PCB connector (see Technical data [►Section 11,
Page 86]).
1. Connect the RS232 interface COM-X1 on the interface module and the in-
terface CPU-X5 together using the patch cable.
2. Connect the wires of the shielded cable in accordance with the connection
diagram.
3. Position the cable shielding, screw it into the shield clamp provided, and
provide strain relief (using a cable tie).
► Connect Ethernet cable (RJ45 plug) to the interface CI-X1.
