Function
• Reads the operation mode of PT.
• The responses above will be returned when PT is in RUN mode. With the
modes other than RUN mode (when RUN indicator is not lit in green), no re-
sponses will be returned even if this command is sent. Sending this command
enables to know whether or not PT is running by checking the presence/ab-
sence of responses.
