General Information
...
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.
Mounting plate
through bolts are McMaster Carr
Super-cheap hot-wire anemometer for airflow in the dome:
...
But response is highly nonlinear and also depends on temperature so we need a temp-and-windspeed calibration surface to be mapped out.
Better version, same width of board and same pinout- 3/19/22
Their version P device is now in stock. Ordered ten of them.

Has hardware compensation for temperature, at least to first order.
But note needs 12V suuply, not 5V like the rev C
Cabling
We can use DB9 hardware off the shelf. To connect unit to DB9 connector:
Scintillation coherence scale for acoustics
