Dual/Input Switchable Analog Interface

Two switchable computer video inputs 15-pin HD inputs with VGA compatible pin-outs VGA through UXGA, MAC-, SUN-, and SGI-compatible Buffered output offers RGBHV, RGBS, or RGsB Switching by front panel, auto-switching, or contact closure Rack-mountable with optional hardware Internal power supply (90 to 140/200 to 240V) Includes one (1) power cord

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 15-pin HD connectors compatible with standard VGA cables and a buffered local monitor on a 15-pin 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 VA 6831FC is 1 U high and rack wide. Input and local monitor cables must be ordered separately. See Interface Cables and Interface Accessories for more information.
