Communications Installation

Wiring Guidelines

•the RJ-11 cable maximum length is 3 meters

•RS-485 maximum length is 1,200 meters (4,000 feet)

•use 24 AWG (minimum)

•use good quality communication grade (shielded twisted pairs) cable that is recommended for RS-485 for port 2 (Belden 9842)

•run the communication cable separately from power and control cables (do not tie wrap your RS-232 or RS-485 cable to the power cable or have them in the same conduit)

•use shielded cable and connect to ground at one end only

•follow proper grounding guidelines for all devices on the bus

Note: Improper wiring and incorrect choice of cables are two of the most common causes of communication problems.

Ports 1 and 2

Port Wall Mount

1RS-232 port (RJ-11 modular telephone jack) is on the motherboard and is generally used with a laptop computer or modem.

2Connections for the RS-485 port are on the terminal block.

Ports 1 and 2: RS-232 RJ-11 Jack and RS-485 Locations

The RJ-11 jack and the RS-485 port are inside the enclosure of the unit.
