TIPS
•“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 
is used, but no monitor with ID number: 2 is found), no response is returned.
If execution of the command is taking some time

To set a timeout for the command response, specify 10 seconds or longer.

Example) 3rd monitor from computer: 30 seconds or longer.
•Provide an interval of 100 ms or more between the command response and the transmission of the next command.
