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.
Code | [STX] | [ADuuu] <Unit Address> [;] <Command> [:] <Parameter> [EXT] | |||
|
|
|
|
|
|
ASCII | (02H) | ( | ) ( ) ( | ) ( ) ( | ) (03H) |
|
|
|
|
|
|
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.
