Analog outputs are then connected to the T7:
U - channel 1 - AIN0
V - channel 2 - AIN1
W - channel 3 - AIN2
sonic speed - channel 4 - AIN3

Relevant pin connections (all of which are copied from the manual)
Output pins from the anemometer (p. 15 of manual):
To change the analog output settings, connect a RS 432 serial port to a windows computer and to the anemometer outputs.
RS 432 serial port pin connections (p.32 of manual):
For the serial connector we were using, pin 2 was white, pin 3 was yellow, pin 5 was orange, but apparently this isn't necessarily generically true.
The windows computer should have WIND software downloaded on it. Follow p. 46 of the manual.

Ordered 10 of these. Be sure to use the RV output pin! Requires 5V supply, clean.
Downside is that the output voltage is a combination of temperature and wind speed. But a separate temperature output is provided, so we should be able to calibrate. dV/d(speed) is also depends on temperature.
