I have a piece of equipment that uses RS485 with RJ45 jacks and I was wondering if I needed special cabling with only 4 of the wires phyically connected in the jack or could I just use regular CAT5 Ethernet cabling with all eight wires present? The specs that I have for the cable only list
4 wires, but they are in the same order and place as a regular CAT5 Ethernet cable. The cable will go between two like devices over RS485 connected by RJ45 jacks.
