4.1CONNECTING NETWORKED SYSTEMS
The optional Network hardware comprises two components:
•
•
The RCU provides the interface to other networked Commander systems. Note that:
•Interconnection can be made by coax (BNC) or CAT5 (RJ45). It is not possible to “mix” the interconnection methods. Having chosen the means of connection, do not fit any other connectors.
•The coax cable connection requires two separate cables (RX and TX) for each link. The CAT5 connection method requires only a single cable per link.
•Network connections are made on a point to point basis. Therefore, a complete system, comprising a number of matrices, will always contain an even number of network cards. See the diagram below which shows a three matrix LAN.
