User Controls
The OG-UDC can be inserted right out of the box into an openGear frame and
immediately be used for many applications, since it is designed to recognize
inputs and perform standard actions automatically. However, you can also
manually configure the OG-UDC using either of two methods:
• Local configuration through DIP switches on the card, or
• Remote configuration through the DashBoard Control System for an
openGear Frame.
