Smart Node Firmware Flashing

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

• PC with the 75F flashtool installed
• Atmel-ICE tool
• M3 Hex Screwdriver

Step 1: Powering and connecting the Smart Node

Remove the Smart Node from the box.

Using an M3 hex screwdriver, unscrew the four fasteners on the back of the Smart Node, then remove the screws, the metal backplate, and the front plastic face.

Connect the Smart Node to a 24VAC or 24VDC power supply.

Step 2: Set the firmware version

Verify that you have the updated firmware file from 75F in the flashtool directory. If using a new firmware version, locate the smartnode config file and edit it. Under the "[FirmwareInfo]" section, edit the firmware version and firmware filename to reflect the new version, as shown below.

Note: the firmware version should only consist of the numbers to the left of the second decimal, as shown above.

Step 3: Flash the Smart Node

Turn on the power supply, then connect the cable from the Atmel-ICE tool to the small 10-pin connector on the right side of the PCB, next to the rightmost mounting hole.

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

To flash the Smart Node, the command prompt is used. If it is not already open, navigate to the flashtool folder in file explorer, then click the address bar and type "cmd", then press enter.

In the command prompt, type the following command, then press enter:

.\flashtool -f smartnode.ini -c flashapp

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.

Disconnect the Atmel-ICE cable from the Smart Node.
