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.
