Download the Extron 200 Matrix Windows software and see what it reports the configuration to be. Then see if that matches the boards installed. Someone could have removed/swapped a board and not set the dips correctly.
Ok will do. The dips appear to be set for binary 0 1 2 3 4 in order from right to left (if you are looking at the front of the unit). There are also two longer dip switches which are all in a single position.
I will try the program and see what that yields. Will I need to connect via RS232? If so I'll need to pick a cable up.
