The XDR query command outputs the data of all sensors except wind.
To request wind data with the XDR command, set the NMEA Wind formatter parameter in the wind sensor settings to T.

The checksum to be typed in the query depends on the device identifier characters and can be asked from the WXT530 series, see the following example.
Example:
Typing the command $--WIQ,XDRxxx<cr><lf> (xxx arbitrary characters) the transmitter responds
$WITXT,01,01,08,Use chksum 2D*72<cr><lf>indicating that 2D is the correct checksum for the $--WIQ,XDR command.
If there are several distinct measurements of the same parameter (according to the transducer table), they are assigned different transducer IDs.
For example, minimum, average, and maximum wind speed are measurements of the same parameter (wind speed) so if all 3 are configured to be shown in the XDR message, they get transducer IDs A, A+1, and A+2, respectively, where A is the transmitter address aXU,A. The same applies for the wind direction. Temperature, internal temperature, and heating temperature have the same unit, thus they are assigned with transducer IDs A, A+1, and A+2, respectively. Accumulation, duration, and intensity for rainfall and hails are measurements of the same parameters so they get transducer IDs A for rainfall and A+1 for hails. Rain and hail peak intensities are assigned with transducer IDs A+2 and A+3, respectively.
For example, for a transmitter with device address 0 the transducer IDs of all the measurement parameters are as follows.
| Measurement | Transducer ID | Type |
|---|---|---|
| Wind direction min | 0 | A |
| Wind direction average | 1 | A |
| Wind direction max | 2 | A |
| Wind speed min | 0 | S |
| Wind speed average | 1 | S |
| Wind speed max | 2 | S |
| Pressure | 0 | P |
| Air temperature | 0 | C |
| Internal temperature | 1 | C |
| Relative humidity | 0 | H |
| Rain accumulation | 0 | V |
| Rain duration | 0 | Z |
| Rain current intensity | 0 | R |
| Hail accumulation | 1 | V |
| Hail duration | 1 | Z |
| Hail current intensity | 1 | R |
| Rain peak intensity | 2 | R |
| Hail peak intensity | 3 | R |
| Heating temperature | 2 | C |
| Heating voltage | 0 | U |
| Supply voltage | 1 | U |
| 3.5 V reference voltage | 2 | U |
| Information field | 4 | G |
| Aux. rain (tipping bucket) | 1 | V |
| Solar radiation | 3 | U |
| Ultrasonic level sensor | 4 | U |
| Aux. temperature (Pt1000) | 3 | C |
| To ensure correct XDR response, activate either hail accumulation or Aux. rain (tipping bucket), not both at the same time. |
