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 cannot be received correctly due to interference from the surrounding environment.
Please ensure that the system or software retries the command if this occurs.
