4.4 HORIZONTAL POSITION ADJUSTMENT

Most monitors and projectors have the ability to adjust the horizontal position of the image, but sometimes 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, as the positions for each computer might be slightly different.

By keeping the VA6835FC’s Horizontal Position control dial in the center position, the image on the display should first be adjusted using the monitor or projector control. If necessary, turn the image using the VA6835FC’s Horizontal Position Control Dial.

To turn off the Horizontal Position Control, turn the adjustment dial fully to the right until a clicking sound is heard.

4.5 HORIZONTAL DELAY REMOVAL

The VA6835FC offers the ability to by-pass horizontal delay. This may be necessary when interfacing with projectors or monitors with sensitive sync inputs, particularly with LCD type projectors. By turning the Horizontal Position adjustment dial fully to the right, the control will “click” into a locked position. In this position, the VA6835FC outputs the same sync types, which are fed into it from the source. In this setting, the VA6835FC will not provide horizontal positioning. The horizontal position adjustment of the image must be made at the display.

4.6 POWER REQUIREMENTS

The VA6835FC may be used with either 90-140V or 200-240V for ease of use throughout the world. Always make sure that the fuse box window above

the power input connector displays the proper voltage. To change the setting, unplug the VA6835FC, and squeeze the clips on either side of the fuse box. Pull out the fuse holder and turn it 180 degrees, resetting it with the proper voltage shown through the window. Re-insert the fuse box making sure that the side clips of the fuse box lock securely into place.

4.7 MOUNTING CAPABILITY

The VA6835FC can be easily mounted into an equipment rack. Four mounting holes are provided on each side of the unit. To mount a single unit, use Altinex 19”-1U Rack Mount Ears (part # DA1294FC). To mount two units in tandem, use an Altinex 19”-1U Rack Mount Shelf (part # DA1293FC). For mounting under the table, optional brackets, such as the TM1271, TM1272, TM1273, or TM1274 can be used.

4.8 BANDWIDTH

The typical bandwidth of the VA6835FC is 420 MHz. The minimum bandwidth is 350 MHz. This exceptionally high bandwidth allows the passing of the third harmonics of the video signal, thus maintaining the highest quality of the input signal.
