APPENDIX
This appendix details the elements for communication between the Monitor and the System Controller. For the communication
parameter settings, refer to the SETUP PROCEDURES on page 9.
■ Communication Protocol
● Data Format
The controller sends messages to operate the monitor in the format shown below.
A transmission message consists of [STX], [Unit Address], [;], [Command], [:], [Parameter], and [ETX]. [Unit Address] is
expressed as [ADuuu] where uuu is in the range of 001 through 099 in decimal form to identify the unit number of the Monitor.
● Command Table
The transmission command consists of three letters followed by the unit address.
