?! — Address Query

This 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.

NOTE

If more than one WMT700 is connected to the bus, they all respond,

causing a bus contention.

where

? = Wildcard

! = Terminates the command.

The response is the following:

a<CR><LF>

where

a = The single-digit WMT700 address that corresponds to

the first character of the address value.

<CR><LF> = Terminates the response.
