Serial Communication Adapters Instruction Manual

The cabling used for an RS-422 or RS-485 serial communications

network should always be a high quality cable such as Belden 8162 or

Alpha 6203C. A two-wire system requires two twisted pairs, and a four-

wire system requires three twisted pairs (the extra twisted pair is

needed for the signal ground).
