INSTALLING YOUR INTERFACE 6
Step 1. Please attach the VA6822 Interface on
the rack using the provided rack mount
hardware or on/under furniture using the
optional TM Series ALTINEX brackets.
Step 2. Connect one end of the input cable to the
video output connector of the source
computer and the other end to the
computer input port of the VA6822.
Step 3. Connect an audio input cable’s 3.5mm
plug to the audio output of a source
computer and the other end to the audio
input connector of the VA6822. If needed,
use a similar cable to connect the audio
output of the VA6822 to a speaker or
audio equipment.
Step 4. Connect the local monitor output
connector of the VA6822 to a local
monitor or display using the appropriate
ALTINEX Local Monitor cables. It is not
necessary to terminate this output with a
termination plug if a local monitor is not
being used.
Step 5. Connect one end of a coaxial cable to the
main output of the VA6822 and the other
end to the RGBHV/RGBS input on the
projector or monitor. Usually either a 4
BNC or 5 BNC coaxial cable
is used, depending on whether the display
devices require composite sync (RGBS)
or separate horizontal and vertical sync
(RGBHV) signals.
Step 6. Connect the main audio output from the
VA6822 through the provided 5-position
terminal block to the input of a sound
system amplifier.
Step 7. Make sure that the dip- switches are set
as described in section 7.
Step 8. Using the provided power cable for your
country of usage, connect the power input
IEC connector to the AC wall outlet. The
power supply used in the VA6822 is
universal so it can accept from 100 VAC
to 240 VAC 50/60Hz. It is not necessary
to change any voltage selection settings
on the VA6822. The LED on the front and
back panel of the VA6822 will light
GREEN if the appropriate input signal is
present and will remain RED if a valid
input is not detected.
Step 9. It is recommended that you move the
VA6822’s horizontal position dial to the far
right facing the front until it clicks. This will
disable the movement of the horizontal
position of the image. The horizontal
position of the image should first be
adjusted using the control provided by the
monitor or projector. If further adjustments
are still required, then image can be
adjusted using the horizontal position
control dial located on the front of the
VA6822.
Step 10. Adjust the equalization channels for the
Red, Green, and Blue channels to get the
best possible image on the display. It is
recommended to increase equalization on
all three channels simultaneously until the
picture is perfect.
