Welcome! Thank you for purchasing the Alcorn McBride DMX OverRide™. The DMX OverRide allows you to take manual control of your DMX network. In normal operation it simply feeds through your DMX stream. But activate any of its remote inputs or pushbuttons, and it automatically overrides the streams with any of three pre-programmed looks. That makes the DMX OverRide ideal for fire alarm lights, work-light presets, manual Blackouts, and much more.
Rear Panel The rear panel of the DMX OverRide includes the DMX Input and Output connectors, the configuration DIP switches, and the Power connector. Power Connector DMX Input Configuration Configuration DMX In DMX Out Remote Input Connections Rear-Panel DIP Switch Settings If possible, it’s a good thing to make sure the rear-panel DIP switches are set the way you want before installing into the rack. The DMX OverRide rear panel contains two banks of DIP switches.

Front Panel The Front Panel of the DMX OverRide includes the Scene Select pushbuttons, the Resume pushbutton, and the Power LED. Each pushbutton also turns Green, Red, or Orange to indicate a particular operational mode or status. The color of the Power LED indicates power status. Scene Selection Buttons Power Status LED Resume/Pass-Through Power Status LED The Power Status LED indicates power status as follows: GREEN – The unit is connected to input power and the battery is fully charged.
Resume Button Pressing the Resume Button will always cause the DMX OverRide to pass DMX data from the input to the output. The button’s multi-color LED indicates the following: GREEN – Resume Mode is active and DMX is actively detected on the input and being passed to the output. ORANGE – DMX is not detected on the input. If the Dropout Enable mode is activated with the rear-panel DIP switch, Scene 1 will activate and the corresponding Scene 1 button will be Green.
Resume Code Feature For applications where you would like your lighting console (or lighting programmer) to resume the lighting without being in front of the DMX OverRide, you can use the Resume Code feature. To do so, the first step is to verify that DIP switch number 6 is OFF.
Applications Here are some ideas of how the DMX OverRide can be used in your installation. Worklights or Maintenance Lighting Many times the person who’s in charge of running the lighting console isn’t around when it comes time to clean the place, or do some work on the theatre. Set up a Work Light preset where the house lights and other general lighting are activated by recording this preset to Scene 2 or 3.
