Table 2: Polling Loop Wiring Using Shielded (or metal conduit) one side of the shield to ground.
Wiring Notes and Recomendations
Twisted, stranded, non-shielded cable is recommended. Avoid sharp bends in the wire.
Shielded cable, running Aux power in the same jacket, and/or running wire in metallic conduit increase the
capacitance of the wire run, which limits distances.
Observe device and control requirements on serial number vs. dip-switch mode.
Avoid running the cable near keypad wiring, intercom, or AC power lines, anything emitting RF noise.
If the V/Plex device will go serial the device has to be programmed as serial.
Shielded wire should have one end of the shield to good Earth Ground.
