The UC40 is a 40-button single system USB controller. The easy to read color coded buttons provide essential show control functions for PlaybackPro Plus.

Each version of macOS has specific settings which have a great impact on playback performance. Before you begin, please visit www.dtvideolabs.com/preflight.This page also includes a link to a printable PDF if needed.

Your controller is ready to use. If a dialog box appears or the green LED light does not illuminate on your controller proceed to the steps in the next section.

DT Videolabs USB controllers are custom key- boards and will communicate with the Mac via keystrokes. When the controller is con- nected to a computer for the first time a dia- log box may appear stating that the keyboard cannot be identified. Click “Continue” to go through the steps for keyboard connection.

If you plug in the controller and you are not presented a dialog box as shown, go to System Preference > Keyboard and select “Change Keyboard Type”.

The next dialog will ask you to press a key which is not available on DT Videolabs con- trollers. Press the “esc” key on the Mac key- board and then click on the “Skip” button to proceed to the final step.

Select the “ANSI” (United States and others)”. Selecting any other keyboard option will not allow the controller to function properly.
