E5jK Digital Controller Write Protocol

The E5jK Digital Controller Write Protocol writes and controls various settings in remote mode for the Controller connected to the Serial Communications Board via RS-232C or RS-485 cable.

Note Negative values cannot be written. All values must be set as unsigned BCD.

YES:	User settings are required for the 2nd or 3rd operands of PMCR.
NO:	Send word allocation:	Set the constant 0000 for the 2nd operand (S).
	Receive word allocation: Set a dummy word (e.g., DM 0000) address for the 3rd operand (D).
