The DCS-200's command protocol is compatible with GNU getopt parsing. Every
parameter of the command has an option character associated with it. A <CR> carriage
return (ASCII 13) terminates the command.
A command response is sent after each command is processed. This response consists of
the command, followed by the error code, a line feed <LF> and a special termination
Query type options are available for the commands. The order of precedence for
processing query option arguments is help (--help), query (-?), and list (--list). If more than
one query option is sent in a command, the option with the highest precedence is
processed, and any others are ignored.
Help Query — Commands have a "help" query option associated with them, (--help). This
query lists all option flags and parameters for the command in the following format:
The order of the option characters in the command does not
ITYPE -i 2 -t 1<CR>
ITYPE -t 1 -i 2<CR>
When a command is successful, the error code is a 0 (eERR_OK), or some
When a command is not successful, the error code is a negative value. A
preliminary list of the error codes is included. Refer to the
on page 130 for details.
