Video Connectors
The system uses a 15-pin high-density D-subminiature connector on the front and back panels for attaching a VGA-
compatible monitor to your system. The video circuitry on the system board synchronizes the signals that drive the red,
green, and blue electron guns in the monitor.
Guidelines
NOTE:
When a monitor is connected to the front panel, the back-panel keyboard, mouse, and video are all disabled.
This system provides two video connectors, one on the back panel, and one on the front panel. If the monitor is
connected to the front-panel video connector, the back-panel video connector is disabled.
The keyboard and mouse must be connected to the same panel as the monitor. For example, if the monitor is
connected to the front-panel video connector, the keyboard and mouse must also be connected to the keyboard/mouse
front-panel connector. This connector is a PS/2 connector and the keyboard connection is the default. To use both the
keyboard and mouse from the front-panel connector, you must use a Y-cable.
If you reconfigure your hardware, you may need pin number and signal information for the video connector.
