NOTE: The HEGS5300 CCTV Keyboard is supplied with a standard 7-foot flat telephone cable. It is strongly recommended that twisted-pair data cable is used from the RJ11 Termination Box when long cable lengths are required to eliminate any data problems. Any cable length in excess of RS232 standards (50 feet) requires line driver units (model number PTE102).
