Communication commands
The laser is delivered set in Auto-start mode (see section 5.1 for Auto-start sequence description). As long as DC power
is supplied to the system the temperature control elements are always operating to reach set-point values and the
laser will be idle waiting for the next command. All arguments are in lower case and separated by a space (ASCII 32).
For more information during system integration contact your local sales representative.
