4.2LOCAL MONITOR OUTPUT (15-PIN HD CONNECTOR)

The 15-Pin HD connector output is used to connect the local monitor to the interface.

This is a fully buffered output, eliminating reflections often caused by “Y” type monitor breakout cables. This output does not have to be terminated if unused. The Local Monitor output is buffered so that it can drive a distance up to 25ft with high-resolution coaxial cable. The output is VESA compatible for VGA through UXGA signals, but can also be used to transmit signals to other types of local monitors using designated ALTINEX adapter cables such as MAC, SUN, SGI, or RGB.

offers the main output with 5-BNC connectors. By connecting to the appropriate connectors of the VA6822, it can provide RGSB, RGBHV, or RGBS output signals.

With these connectors the VA6822 can be

connected to	compatible data projectors using
3 coax, 4 coax, or 5 coax cables.

4.4 HORIZONTAL POSITION ADJUSTMENT

Most monitors and projectors have the ability to adjust the horizontal position of the image, but in some instances it is helpful to be able to control this feature at the interface. This control is especially useful when multiple computers are switched to a single display and the horizontal positions from each computer are slightly different.

With the VA6822’s horizontal position control dial in the OFF (locked) position, first the image should be adjusted using the control on the monitor or projector. Then adjust the image with the VA6822’s horizontal position control dial located on the front panel.

To disable the adjustment of the horizontal position of the image, turn the horizontal position dial fully to the right until a “clicking” sound is heard.

The VA6822’s horizontal position of the image can also be adjusted remotely using an available optional accessory that is inserted into a 3.5mm jack labeled as “Remote H-position”. To enable adjustment of the image’s position, first the H- position dial located on the front panel must be in a locked position. Now using the knob on the optional accessory, the image can be shifted.
