RS-422 Serial Cable
On the Matrix3 LX-COS module, Port A and Port B use the same connector pin-outs as the CueMixer, so the cable connections are swapped from end to end. The cable needed to connect the LX-COS module to the CueMixer should be wired as shown.
Use a two-shielded-pair stranded cable with low capacitance. Pins 4&5 are one pair, and 8&9 are the second pair. (See the appendix for an application note on how to use two channels in an audio snake to run the CueMixer signal.)
