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 we need to make a mechanical part to mount this on tail end of carbon stalk.
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 male to breakout on far end.

Clamps for mounting 20mm OD tubing
Assembly:
- cut carbon tube to 10 inch length
- attach DB-9 connector to flange with two 4-40 screws
- feed ribbon cable through tube, and plug other end into sensor
- test electrical connections and functionality
- glue in both the connector flange and the sensor using 5 minute epoxy
- add mount clamp at midpoint
