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.
Structure of the Protocol
The structure of the ES100j Digital Controller Protocol is shown below.
