3.5 RS232 Wiring

The recommended cable type for RS232 communication is Belden part number 9941. Specifications for Belden cables can be found at WWW.BELDEN.COM.

3.6 RS422 Wiring and Termination

In installations where long cable runs must be used, or in noisy environments, RS422 is the communications standard of choice for point-to-point serial communications. The recommended cable types are Belden p/n 3084A, or Belden p/n 3082A. For long cable lengths, make sure you consider voltage drop over the length of the cable, and use cable of an adequate gauge.

NOTE: The RS422 receiver within the LRP2000 controller has fail-safe protection circuitry, which eliminates the need for any pull-up or pull-down resistors on the RS422 lines.
