E5@K Digital Controller Write Protocol
The E5@K Digital Controller Write Protocol writes and controls various settings in remote mode for the Control-
ler connected to the Serial Communications Unit/Board via RS-232C or RS-485 cable.
Note Negative values cannot be written. All values must be set as unsigned BCD.
