Making an RCP comm cable
Use the following guidelines to make an RCP cable:
• At one end, attach a female 4-pin XLR connector.
• At the other end, attach a male 4-pin XLR connector.
Connect pins straight through.
• Use at least 18 gauge wire paired with 20 gauge wire for power (pin 1), 18
gauge wire paired with 20 gauge wire for ground (pin 4), and 20 gauge
twisted-pair wire for communications (attach one pair to pin 3 and the
other pair to pin 4).
• The cable can be up to 1000 feet (304.8 meters) long.
• Power is supplied by the SGS 408.
