To poll for an MWV message, type the following query:
$WIPKQ,*78<cr>| $WIP | Fixed text at the start of the query |
| K | Default transmitter device ID |
| Q | Marks the message as a query |
| * | Asterisk, indicating that the next field is the checksum |
| 78 | Two-character checksum for the device ID |
The data in the response follows the MWV message format, but the header is different:
$P<ID>MWV,<a.a>,<R>,<s.s>,<U>,<S>*<CS><cr><lf>| $P | Fixed text at the start of the response |
| <ID> | Transmitter device ID |
| MWV | Marks the message as a wind speed and angle message |
After receiving a query that uses its device ID, the transmitter replies with an MWV message containing the wind data. An example of a query with device ID "A":
$WIPAQ,*72Example of response:
$PAMWV,50,R,0.0,M,A*04The following table lists checksums and polling strings for queries with some typical device IDs.
| By default, the transmitter does not respond to an MWV query. You can enable the response with the SETMES command by naming any of the messages (0 ... 3) MWVQUERY. See SETMES. |
