When the previous command WS aV! is given, the response is the

following:

a<watchdog><WS_unit><SDI-mode><spare><CR><LF>

where

a = The sensor address.

<watchdog> = The 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 submode setting. The options are:

+0 = SDI-12 submode A

+1 = SDI-12 submode B

<spare> = 1 digit for factory use, format: +c

<CR><LF> = Terminates the response.

The above are verification data fields.

Continuous Measurements (aR0!)

A sensor that is able to continuously monitor the phenomena to be

measured, does not require a start measurement command (M!). The data

can be read directly with the R0! command.

WS425 uses this command when the sensor is set to work in SDI-12

submode B. The command retrieves averaged wind data and gust wind

data. The averaging time window is selectable between 3 and 3600

seconds.

The command is the following:

aR0!

where

a = The sensor address.

R0 = The send continuous measurements command.

! = Terminates the command.
