<CR><LF>
Terminates the response.
The above are measurement data fields.
Missing Readings
If data is missing due to a measurement problem (for example, blocked paths between
transducers), the measurement data is replaced with 999.9.
Example
Example of the command and response when data is missing:
7D0! 7+999.9+999.9+999.9+999.9+999.9 <CR><LF>

WS425 A/B SDI-12 Message for V Command
When you have given the commands aV! and aD0!, the response is the following:
a<watchdog><WS_unit><SDI-mode><spare><CR><LF>
a
Single-digit WMT700 address that corresponds to the first character of the address
value
<watchdog> Number of times the watchdog has triggered. Ideally should be zero. Format: +(c)c
<WS_unit> Wind speed unit. The options are:
• +0 = mph
• +1 = kt
• +2 = km/h
• +3 = m/s
<SDI-mode> Current sub mode setting. The options are:
• +0 = SDI-12 sub mode A
• +1 = SDI-12 sub mode B
<spare> 1 digit for factory use, format: +c
<CR><LF> Terminates the response
The above are verification data fields.

Requesting Cyclic Redundancy Check
Error detection capability can be enhanced by using the aCC! or aMC! command to start
the measurement. These commands have the same function and send the same response as
commands aC! and aM! respectively. The
dierence is that Cyclic Redundancy Check is
appended to the data returned by the aD0! command.
