ABOUT YOUR INTERFACE 2
There are a great variety of computers and computer video cards on the market today. There are also numerous data monitors and large scr een data projectors. When displaying a computer image on a large screen data projector or on a large screen monitor, it often becomes clear that some computers are not always compatible with these display devices. The
VA6805SX/DA 1926AV
that you have just purchased from ALTINEX is designed to resolve this incompatibility.

fully buffered outputs: a main output on 5 BNC connectors provides RGBHV, RGBS, or RGsB, and a pass-through 15-pin HD monitor output. The monitor output is typically used to transmit signals to a local monitor. 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

4.1. INPUT
The 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. T his allows greater flexibility and versatility of the
VA6804SX/VA 6805SX/DA1926AV.
output cables for various computers are available.
Table 4.
DA1926AV
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 pass­through only). With these connectors, the
VA6803SX/ VA6804SX/ VA6805SX

4.3. LOCAL MONITOR OUTPUT
A buffered output is very helpf ul in connecting your local monitor to the interface. This output is fully buffered; therefore, any reflections are totally eliminated. The output is provided th rough 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 pr ojector set up.

4.9 EQUALIZATION
Equalization is a means of boosting Red, Green, and Blue signals at high frequencies with digital adjustment knobs when using cable runs over 100 feet. This works f or up to 300 feet or m ore of cable depending on the type of cable. The att enuation of red, green, and blue signals due to long cables may be effectively removed.

The
VA6803SX/VA 6804SX/VA6805SX/DA1926AV
will operate successfully as long as cables are attached properly and other technical specifications are followed. There are no other adjustments necessary to operate the unit.
7.1 HORIZONTAL POSITION CONTROL
When in the OFF position, the switch will disable the adjustment of the horizontal position of the image through the dial located on the input side plate. If the Horizontal Position knob is in the ON position, the horizontal position control of image is possible through the knob on the side of the
VA6804SX/VA 6805SX/DA1926AV
With the Position knob in the OFF position (Horizontal position control disabled), it is recomm ended to first adjust the horizontal position of the image using the monitor or projector’s Horizontal Position control. If the horizontal position of the image needs further adjustments, adjust it with the dial located on the
