Omron CQM1H-SCB41 operation manual Appendix H, ES100j Digital Controller Protocol

	Appendix H
	ES100j Digital Controller Protocol
The	ES100j Digital Controller Protocol controls in remote mode and reads various settings from the Controller
connected to the Serial Communications Board via RS-232C or RS-422A/485 cable.
Note	Negative values cannot be written. All values must be set as unsigned BCD.
