Multisensor Provisioning

Note: Before beginning the Smart Node provisioning process, you will need the following components:

• Flash Station PC
• Atmel-ICE tool
• Smart Node
• M2 Screwdriver

Step 1: Powering and connecting the Multisensor

Remove the Multisensor from its box.

Using fine-tipped screwdriver, press down on the tab within the hole on the top of the Multisensor, then pry apart the front face to access the PCB.

Connect the Multisensor to a Smart Node using a 3-pin cable, and connect the Smart Node to a 24V power supply:

Step 2: Flash the Multisensor

Turn on the power supply, and connect the programming cable to the bottom-most pin header on the Multisensor as shown below:

Note: ensure that the programming cable is connected to the AVR port on the Atmel-ICE tool.

The connection is polar; if the following step fails you may need to reorient the connector.

To flash the Multisensor, the PowerShell terminal is used. If it is not already open, double-click the PowerShell icon on your desktop to open it.

In the PowerShell terminal, type the following command, then press enter:

.\multisensor

Once you press enter, the terminal should begin to run the command, with the output reflecting this. It takes approximately four minutes for this flash to complete. Once you see the cursor reappear, the flash has completed.

Step 3: Testing the Multisensor

Once flashing is complete, disconnect the programming cable from the Multisensor. Then, on the Smart Node, navigate to the Inputs screen.

You should see temperature and humidity values fluctuating from the Multisensor input.

Next, scroll down to the bottom of the inputs screen to locate the CO2 value:

Ensure that the CO2 value is reading, and that the value is within expected range for your environment (usually ~400-600ppm). This value may take several minutes to appear, but do not proceed without confirming that it does.

Once these inputs have been confirmed, disconnect the Multisensor from the Smart Node, reattach the front face, and return it to the box.
