Appendix I - Polled Mode Commands
ASCII Polled (UV and Polar)
When in the Polled mode, an output is only generated when the host system sends a Poll signal to the WindObserver
consisting of the WindObserver Unit Identifier – that is, the relevant letter A – Z.
The output formats are otherwise as described above.
The commands available in this mode are:
Description Command WindObserver response
WindObserver Unit Identifier A ….. Z Wind speed output generated
Enable Polled mode ? (None)
Disable Polled mode ! (None)
Request WindObserver Unit Identifier & A ….. Z (as configured)
Enter Configuration mode *<N> CONFIGURATION MODE
Where <N> is the unit identifier, if used in a multi-drop system then it is recommended that ID’s A to F and KMNP are not
used as these characters can be present in the data string.
It is suggested that in polled mode the following sequence is used for every poll for information.
? Ensures that the Sensor is enabled to cover the event that a power down has occurred.
A-Z Appropriate unit designator sent to retrieve a line of data.
! Sent to disable poll mode and reduce possibility of erroneous poll generation.
When in polled mode the system will respond to the data command within 30mS with the last valid data sample as
calculated by the Output rate (P Mode Setting).
If the unit is powered down after use or upon switch on then allow 3 seconds from switch on before sending poll
commands.
