Command Protocol

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.  

S

Command example:

ITYPE -i 2 -t 1<CR>

Or

ITYPE -t 1 -i 2<CR>

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 
character (\x4).  

When a command is successful, the error code is a 0 (eERR_OK), or some 
positive value. 

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. 

S

Command response example:

ITYPE -e 0<LF>

</x4>

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:

S

Help option example:

IBRT --help<CR>

Response:

Description:  Input Brightness Adjust

Command Format:  IBRT -i(input) -b(bright)

The order of the option characters in the command does not 
matter.
