  11. Dissolved Oxygen Node Assembly, Assembling the Node Interior: passo 11, imagem 1 %32 Dissolved Oxygen Node Assembly, Assembling the Node Interior: passo 11, imagem 2 %32 Dissolved Oxygen Node Assembly, Assembling the Node Interior: passo 11, imagem 3 %32
    • Put the battery into the node enclosure between the area of the standoffs

    • Place the board with the modem and the GPS antenna onto the standoffs and GENTLY screw the board in place. Then stick the modem and GPS in the locations highlighted.

    • Stick the carrier boards onto the sides of the interior. Make sure to place the carrier in their respective location highlighted.

    • Follow the wiring diagram when wiring the carrier boards to the circuit board.

  12. Dissolved Oxygen Node Assembly, Adjusting Solar Charger Potentiometer: passo 12, imagem 1 %32 Dissolved Oxygen Node Assembly, Adjusting Solar Charger Potentiometer: passo 12, imagem 2 %32 Dissolved Oxygen Node Assembly, Adjusting Solar Charger Potentiometer: passo 12, imagem 3 %32
    • Obtain USB power supply, plug into a laptop, and set output to 5.9V

    • Check the voltage with a voltmeter (you may have to set the power supply to ~5.8V for the voltmeter to read 5.9V)

    • Plug in the green terminal block from the power supply into the Open-Storm board solar port.

    • Confirm the solar charge LED is off.

    • Plug in a dead battery to the battery port. This step will not work with a charged battery

    • CAREFULLY turn the silver potentiometer next to the charge controller IC with a small flathead screw driver until the charge light turns on.

    • Although the screw has a phillip screw head, using a phillip screwdriver may damage the potentiometer. The hole in the center is too shallow for most screwdrivers. It is easier to use a flathead screwdriver!

    • The sensor lights in the node should be turned on

    • Attach the lock to the side of the node

    • Make sure to twist the cable gland so that the wires are snug together

    • If the DO readings emit a reading of 0 mg/L then:

    • Make sure the DO circuit board is facing the correct orientation (refer to step 2)

    • Make sure that the jumper wires are connected correctly and securely. Likewise, check if the RX and TX wires are swapped.

    • Check the connection between the adapter cable and the housing of the DO sensor to see if it is tight and sealed.

    • Make sure there is adequate electrolyte solution in the cap of the DO sensor.

    • If the steps above fail, replace the DO sensor circuit board.
