WIRING GUIDELINES AND BEST PRACTICE INFORMATION
(continued)
10.
If the total accumulated cable length of the RS-485 network exceeds 1200 ft; then the longest cable run, presumably at port 1 of
the PCP, should be terminated with a 120 ohm resistor between its data terminal nodes (pins 2 and 1 of PCP´s RJ45), at the end of
the cable run. Whenever total combined length of cable is for less than 1200 ft, the termination resistor is not needed. It is important
to note that, when combined cable runs exceed 1200ft on the entire network there should be 2 termination resistors. One is already
included inside the IC, so the only additional need is 1- 120 termination resistor at the far end side of the cable run.
11.
If the installer decides to use shielded CAT5e or CAT 6 cable on the installation, then cable’s shield should be connected to the
panel’s side earth GND terminal only.
