    Hi all.

    I'm planning on installing some structured cabling from my C-Bus cabinet to my comms cabinet.

    I want to terminate using an RJ45 connector to plug into on the 5500PC and run that to a 9-pin Sub-D faceplate. I'll then use a standard serial cable to connect my server to the faceplate.

    Which pins on the RJ45 go to which pins on the Sub-D?

    I believe it's just a 3 wire serial link, no hardware handshaking.

    Thanks very much guys.
