■ RS-422/485 Serial Communication (Separate Option)
RS-422/485 method is more stable for electric noises than any other communication
methods as it communicate signals in the voltage difference. In addition, the wiring should
be done away from AC power cable or other electric wires. The shield coax cable should be
used in any case. The recommended distance in use is the dedicated line within 1.2km.
