Cable Requirements

RS-232 Serial Cable

three conductor, shielded, stranded, AWG 24 wire (Belden 9533 or a larger gauge)

50 foot maximum length (per RS-232 industry specification - greater lengths are not recommended)

RS-485 Network Cable

one twisted, shielded pair of conductors, stranded, AWG 24 wire (Belden 9501 or a larger gauge)

4,000 foot total network length (per RS-485 industry specification)

extended network configurations are possible – refer to the Network Wiring Application Note (P/N 01824-002) for
extended network configurations of up to 5,000 feet per star line and 16,000 feet total network length

Telephone

1 pair copper phone line

NOTE: EntraGuard Silver is not to be used with a Centrex, PBX, or digital phone line. Only use a Plain Old Telephone
Service (POTS) analog phone line.

Input Power

two conductor, stranded, AWG 18 wire (Belden 8461 or a larger gauge)

NOTE: On long power cable runs, the cable resistance causes a drop in voltage at the end of the cable run. Be sure your
power supply does provide 12 VDC at the end of the cable run.
