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 100 feet of 4-pair cable from Digikey- 2467CSL005-ND
Initial tests, 3/18/2022
Wired up one of these units, using 90-degree 0.1 inch header. Used four-pair shielded twisted pair cable:
Red: +5V
Black: Ground (all pair ground tied together on sensor end, leave output low side cables floating at our end of cable)
red/white: RW out
yellow/white: Temp out
white: "output" but we will most likely use RW above.
full scale is ostensibly 60 mph which is ~28 m/sec
But response is highly nonlinear and also depends on temperature so we need a temp-and-windspeed calibration surface to be mapped out.
