Anemometer

General Information

Instrument: 3 Axis Ultrasonic Anemometer 1590-PK-020/w with 4 14-bit analog outputs

Current Device Status (12/2/2021)

Analog output settings are configured to read out U, V, W, and sonic temperature at 32 Hz with an output range of 0-5 V. For U, V, W, this range has been set to correspond to -5 to +5 m/s and for temperature this range corresponds to -40 to 70 degrees C.

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.
