The ?! command queries for the WMT700 address.
When you use a question mark (?) as the address character with the a! command, WMT700 responds as if it was being addressed on the SDI-12 bus. Regardless of its address, WMT700 responds to the command, which allows you to determine the address for the wind sensor.
| If more than one WMT700 is connected to the bus, they all respond, causing a bus contention. |
