4.1. INPUT

The VA6803SX/VA6804SX/VA6805SX/DA1926AV uses a 15-pin HD connector for input, which is compatible with standard VGA pin-outs. This allows the connection of a computer using coaxial cables to a 15-pin HD connector cable. This allows greater flexibility and versatility of the VA6803SX/ VA6804SX/VA6805SX/DA1926AV. The input and output cables for various computers are available.

4.2. MAIN RGBHV OUTPUT

BNC connectors are considered standard connectors for audio-visual systems. They offer a better quality connection for high-resolution video signals. They also allow easy cable maintenance in the field. This output offers RGBHV, RGBS, and RGsB output signals (RGsB type input is pass- through only). With these connectors, the VA6803SX/ VA6804SX/ VA6805SX can be connected to compatible projectors using 4 coax or 5 coax cables.

4.3. LOCAL MONITOR OUTPUT

A buffered output is very helpful in connecting your local monitor to the interface. This output is fully buffered; therefore, any reflections are totally eliminated. The output is provided through a 15-pin HD connector.

4.4.HORIZONTAL POSITION ADJUSTMENT KNOB

Although most monitors and projectors are fully capable of adjusting the horizontal position of the image, in some instances it is helpful to adjust the horizontal position at the interface. This control is also helpful when using multiple computers.

In some cases, adjusting the horizontal position at the interface may simplify the projector set up.

4.5. EXTERNAL POWER ADAPTER

The VA6803SX/VA6804SX/VA6805SX/DA1926AV

is powered using a 9VDC 500mA adapter. The power regulation is provided inside the unit. The adapter uses a 2.5mm connector with a center conductor (+) and a shell (-). A selection of several power adapters is available for different countries from 110 VAC to 240 VAC.

4.6. MOUNTING CAPABILITY

The VA6803SX/VA6804SX/VA6805SX/DA1926AV is designed for easy mounting to a table, wall, or inside a rack using the MB1001 mounting brackets. Two mounting holes are provided on each side of the unit for the mounting brackets.
