SFC SKI Posted October 1, 2017 Share Posted October 1, 2017 Does LOR use all four pairs of wires on a cat5? I have 2 100ft buried runs under a railroad. (Yes got permission for that) each cable has one broken or touching pair somewhere in the run. Link to comment Share on other sites More sharing options...
k6ccc Posted October 1, 2017 Share Posted October 1, 2017 No. Only pins 4 & 5 ( normally the white/blue pair) are used for data. Pins 3 & 6 (in most cases the white/green pair) MAY be used to supply power from a controller to a nearby InputPup or Easy Light Linker. The others are not used.
