• "ERR" is returned when there is no relevant command or
when the command cannot be used in the current state of
the monitor.
• If communication has not been established for reasons
such as a bad connection between the PC and monitor,
nothing is returned (not even ERR).
• "ERR" may be returned when a command can't be
received correctly due to interference from the surrounding
environment.
Please ensure that the system or software retries the
command if this occurs.
• If no monitor has been assigned the designated ID number
(e.g. if the command IDSL0002
with ID number: 2 is found), no response is returned.
If execution of the command is taking some time
