User Interface Commands
FOT Lab Kit User’s Manual 4-29
CTRL+Q Report the Most Recent Measurement
When in Remote Control mode periodic reporting of temperature
through the serial interface is disabled even though sampling and
creation of temperature reports can be invoked as background tasks
(CTRL+I command). The CTRL+Q command instructs the device
to report the most recent measurement created for each active
input. The format of the report is exactly the same as when in
automatic-reporting mode except that it is preceded by the echo of
the CTRL+Q character. Under normal circumstances the user
would alternate between CTRL+I (create report) and CTRL+Q
(transmit report). If you transmit CTRL+Q twice without an
intervening CTRL+I, you will receive a copy of the old report
created by the most recent CTRL+I command.
When used in Standard mode the CTRL+Q command simply
enables RS-232 serial data output previously inhibited by the
CTRL+S command.
CTRL+R Exit Standby Mode / Run
This command is valid ONLY when the device is in Standby mode
(CTRL+T command) or Remote Control mode (CTRL+E
command).
When in Standby mode CTRL+R instructs the device to return to
Standard-mode operation.
When in Remote Control mode CTRL+R enables, but does not
initiate data sampling.
If command is successfully executed the CTRL+R character will be
echoed back to the host, else a question mark ('?') will be returned.
CTRL+S Disable Serial Data Output
This command is valid ONLY when the device is in Standard mode.
Use CTRL+S to temporarily disable periodic reporting of
temperature data. A common reason for doing this is to prevent the
data you are looking at from scrolling off the screen. Use CTRL+Q
to restart periodic reporting.
