The VA6831FC is a dual input/switchable interface designed to allow the connection of two computer video sources to a single scan-rate compatible monitor or projector. The VA6831FC is compatible with VGA thru UXGA, MAC, SUN, and SGI.

The VA6831FC provides two inputs on 15-pin HD connectors that are compatible with standard VGA cables. For each input, the VA6831FC offers a buffered local monitor output on a 15-pin HD connector. The local monitor outputs also pass through ID Bits, which may be necessary for proper boot-up resolution.

The main output provides RGBHV, RGBS, or RGsB type signals, 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 RGsB. The VA6831FC also allows the ability to connect and switch audio sources for each computer.

The VA6831FC offers three switching methods: 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, as well as an ID Bit DIP switch for laptop use. Individual Horizontal Positioning Disable switches are also available.

The VA6831FC is 1U high, 1/2 rack wide. Input and Local Monitor Cables must be ordered separately. See Interface Cables and Interface Accessories.
