1. You will need to install cutecom

• Go to the raspberry pi logo in the top left of the screen and click
• Go top preferences and add software and search for cutecom and install from here. You will need the common password set earlier.

2. You will need to wire up the Sonic Anenometer as seen in the pictures below and in the manual linked below.

• User Manual

• While testing you will need to use the green serail board provided below. Follow the instructions in the manual to wire the ports to the number on the board.
• You will need to use a male to male connecter as the usb is serial type male and the green board is also type male. Their is a null modem in between during testing to ensure the correct rs232 read pin on the usb lines up with the write pin of the Anemometer. This will not be needed in the final configuration as you will be wiring up a female connector later but for testing it is needed.

3. Once its wired up you should be able to go to cutecom and follow the below link to an unlisted youtube video showing how to setup the custom format to include all of the 2d and 3d data.

• Instrument

• Wiring Box

• Wires - While the color will ultimately depend on the cord you use to wire the instrument, the colors shown here are just for easy reference to the different power signals.

• Red - Power (positive)
• Blue - Power (Ground, negative)
• Grey - V1, 3D Wind Speed
• Yellow - V2, Wind Direction
• Green - V3, Wind Elevation
• White - V4, Sonic Temperature
• Brown - Signal Reference
• Pink - Unused

By now, you should have your Raspberry Pi computer completely set up, with a DAQ HAT. To continue, you will need:

• some sort of DC Power Jack connector,

• a small screwdriver for undoing and tightening the screws on the DAQ HAT channels,

Optionally:

• a multimeter/power sensor,

• a fan

1. Wire the Anemometer's Electrical Box
   1. Red to +PWR
   2. Blue to EARTH GND
   3. Grey to V1
   4. Yellow to V2
   5. Green to V3
   6. White to V4
   7. Brown to VREF
2. Connect the DC Power Jack to power
   1. Connect the red wire to the positive connection
   2. connect the blue wire to the negative connection
3. Optional: If you would like to test the probe prior to connecting it, follow this step. You will need the optional materials. If you do not want to test the probe, skip to step 3.
   1. For each wire labeled V1, V2, etc., place the red probe onto the labeled pin V1,2, etc., and the black probe to VREF (Brown wire)
   2. You should see some voltage coming through on the voltmeter.
4. Wire the probe into the DAQ HAT
   1. Grey to CH0
   2. Yellow to CH1
   3. Green to CH2
   4. White to CH3
   5. Brown to GND
5. If you have properly set up the ADPAA and DAQ HAT, you can now run the python program that coincides with your instrument and observe the data.
