Refer to the following illustrations for examples of wiring connections.
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).
