For connection between units, connect the [PROCESSOR] side with a higher-level unit.
The interface is RS-422 based on asynchronous communication method (19,200 bps).
Alarm sounds and panel brilliance data are outputted from RPU-013 to the control unit,
and key and control knob information and track ball data re outputted from the control
unit to RPU-013. The cable length from RPU-013 to the last control unit is 31 m at
longest taking supply voltage drop into consideration.
