Step 1: Configure the Port

• Connect the WIAnode to your computer.

• Open the USB drive that appears and modify the config.txt file by setting the P2 port to input. Ensure that the Wi-Fi SSID and password are filled in.

• Save the file. (Do not save the file multiple times.) Power cycle the WIAnode to restart it.

Step 2: Connect the Sensor

• Use a 3-pin silicone cable to connect the knob to the P2 port on the WIAnode.

Step 3: Connect TouchDesigner to WIAnode

• Open the TouchDesigner example file, click on the WIAnode plugin, and enter the IP address shown on the WIAnode screen into the configuration panel. Enter wianode as the client name and dfrobot as the password.

• Once the plugin displays Connected, the connection to the WIAnode is successful.
