Command Protocol
`çãã~åÇ=mêçíçÅçä
The ACS-2048’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>
`çãã~åÇ=oÉëéçåëÉë
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 96 for details.
S
Command response example:
ITYPE -e 0<LF>
</x4>
nìÉêó=léíáçåë
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:

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