Manufacturer: Hydreon Model Number: 15 User Manual: Here Serial Data Configuration: Baud rate 9600, Data Bits 8, Parity None, Stop Bits 1.

The Hydreon RG-15 has a few key components when it comes to setting up the instrument.

• Sensor - Collects data

• Power Adapter - Connects to a 12V 2A DC Power supply

• Serial Adapter - Allows the Raspberry Pi to read sensor data

• Wires - At the end of the cord, there will be six (6) exposed wires of the following colors:

• Orange - TXD
• Green - Ground
• Yellow - RXD
• White - 3.3V Power
• Red - Power (positive)
• Black - Grounding power (negative)

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

• A Serial to USB adapter (DB9-USB)

1. Connect the power adapter to a DC power supply as given above.
2. Connect the power adapter to the red and black wires
3. Connect the remaining wires to the serial adapter as given above.
4. 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.
