Use this command when there are several devices on the same bus and simultaneous measurements are needed from the devices, or if more than 9 measurement parameters are requested from a single device.
The measured data is not sent automatically. You must request it with the Send data command aD.
Command format:
aCx!| a | Device address |
| C | Start concurrent measurement command |
| x | The desired measurement |
| 1 = Wind | |
| 2 = Temperature, humidity, and pressure | |
| 3 = Precipitation | |
| 4 = Analog input | |

| If x is left out, the query refers to combined data message in which the user can request data from several sensors with just one command. See the following example. | |
| ! | Command terminator |
Response:
atttnn<cr><lf>| a | Device address |
| ttt | The measurement completing time in seconds |
| nn | The number of the measured parameters available (maximum number is 20) |
