The VA6831FC is a dual input/switchable interface designed to connect two computer video sources to a single scan-rate compatible monitor or projector; compatibility is VGA through UXGA, MAC, SUN, and SGI. This unit provides two inputs on 15pin HD connectors compatible with standard VGA cables and a buffered local monitor on a 15pin HD connector. The local monitor outputs also pass through ID bits, possibly necessary for proper boot-up resolution.

The main output provides RGBHV, RGBS, or RGsB signal selectable by a DIP switch setting. If the input signal format is RGBS, or RGBHV, the main output may be RGBHV, RGBS, or RGsB; if the input signal is RGsB, the output must be the same. The VA6831FC allows for the ability to connect and switch audio sources for each computer.

There are three switching options: manual switching using a three-position switch on the front panel, auto-switching on the active signal, or via contact closure with connection being made on a terminal block. A horizontal positioning control is available on the front panel for each source, and an ID bit DIP switch for laptop use. Individual horizontal positioning disable switches are also available.

The VA6831FC is 1 U high and ½ rack wide. Input and local monitor cables must be ordered separately. See Interface Cables and Interface Accessories for more information.
