NX Lighting Controls LX network cable is used to interconnect LX panels, LX devices and LX accessories for a complete communications network. All devices that communicate on the LX network are connected with the same type of single twisted pair cable. Both power and data are carried over the same two wires. The LX system is wired as a topology-free, polarity-insensitive network. NX Lighting Controls supplied LX Network Cables assure proper network communications and should be specified and installed on all LX System projects.
