The DRC provided to you has the option of working wirelessly or using a coaxial cable to provide a wired connection. The wired connection acts as an antenna and is useful for environments where there is a lot of wireless noise, or if you have many systems in a close proximity. It does not provide power to or automatically sync the DRC.
A Nintendo racetrack logo will appear. Press the small red Sync button on the back of the DRC, just below the battery cover. You may want to use the Wii U Gamepad's Stylus to accurately press the sync button.
NOTE: Depending on the firmware installed on the GamePad, the DRC screen may have a 10-digit keypad rather than the four symbols. In this case, enter the PIN code displayed in the parenthesis to the right of the symbol PIN code displayed on-screen.
If the pairing fails, ensure that the Wired/Wireless settings are set correctly. Also, if you are using a wired connection, be sure that the coaxial cable is tightly attached.
If the DRC is paired, the 'Firmware Version' field will display the version information of both the DRH (the CAT-DEV-side of the connection) and the DRC itself. If no DRC is attached then only the DRH information will be displayed.
If your DRC displayed the number pad when pairing, this firmware update will take a bit longer than normal. The progress bar will reach 100%, but it will take a little while longer before control is regained. You will also need to re-pair the DRC after this update, as the update will break the pairing connection.
The amount of time necessary to perform the update may vary. A normal update will only take a couple of minutes and would not require pairing the DRC again. In this specific case, the update may take around 10 minutes to complete.
At this point, your DRC should now be paired and up-to-date!
