Note: Separate the communications cables from the main circuit cables and other wiring and power cables. Use shielded cables for the
communications cables, and properly shielded clamps to prevent problems with electrical noise. When using RS-485
communications, connect S+ to R+, and S- to R- as shown in the diagram below.
2.
Check or set the termination resistor selection at all slaves. Use the description in
for slaves that are converters.
3.
Switch the power on.
