RS-422 & 485 transmit signals with the voltage difference, which are more stable for
electric noises than other communication methods.
In addition, the AC Power Cable or other electric wires should be placed separately, and
the shield cable (0.5Φ or more) dedicated to communications should be applied.
The recommended use distance is within 1.2km.
