2.3 Setting up the control network
The XCU is connected to the control network hub or router via an Ethernet cable (straight-
through, not cross-over) via the C2IP (RJ45) connector. An OCP 400 (Operational Control Panel)
and, if required an MCP 450 (Master Control PC), are also connected to the Ethernet network
via a hub or router. An OCP 400 can also be connected directly to the XCU using a (cross-over
or a straight-through) Ethernet cable.
The IP address and other options for the Ethernet connection can be set up in the XCU menu.
