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.

So sensor end is DB9 pins. If we use straight-through M to F DB9 cable (no swap of pins 2 and 3) then readout end is also DB9 pins. So we need DB9 female to breakout on far end.
Easiest to just solder 4 wires into a panel mount DB9 connector.

We need two channels of A/D conversion for each unit. Conservatively, each sensor consumes 60mA at 12V. Assume we deploying ten of them. That means we need a 1A, 12V power supply. There is on-board voltage regulation on the sensor so this doesn't need to be super-well regulated.
Box needs a a power supply for the sensors as well as A/D converter function and a data collection computer. Labjack U3-LV has 16 single-ended inputs, enough for 8 devices with both wind and temperature. We should run it off a dedicated computer, NUC or R-Pi.
