Appendix D. EDS400 Command Set
Features/Definitions
• Command syntax:
An RS-232 command can have one of two formats:
1. [SOM] [command number] <command parameters> [CR]
2. [SOM] [command number] <command parameters> [CR]
<caption/text data> [EOM] [CR]
Spaces (20 hex), tabs (09 hex), or commas (2C hex) can be used to separate
command parameters. The encoder will acknowledge a valid command with [CR][LF]. If
a command error occurs, it will respond with [CR][LF][error code]. If an invalid command
number is received, it will respond with [CR][LF]1. The encoder uses XOFF/XON flow
control to prevent buffer overflow.
