FAQ (FREQUENTLY ASKED QUESTIONS) 9
No: Question Answer
1 When and
why do I
need to
use the
Horizontal
Position
Control
Knob? The Horizontal Position
Control Knob enables or
disables the control of the
horizontal position of the
image using the control knob
of the
VA6803SX/
VA6804SX/ VA6805SX .
First, adjust the horizontal
position using the monitor or
projector control, and then
use the horizontal position
control of the
VA6803SX/
VA6804SX/ VA6805SX
, if
needed.
2 What
jumper do I
set to
receive the
composite
SYNC
output? If the desired output signal is
composite sync, then set the
HV PRES Jumper (J5) to
OFF and connect only 4 wires
(RGBS) to RED, GREEN,
BLUE, and H/C SYNC
connectors. The default
position for J5 is ON.
3 When and
why would
I use the
Sync on
Green
Jumper,
although
the unit
does not
separate
Sync from
Green?
The VA6803SX/VA6804SX/
VA6805SX does not separate
the Sync signal from the
Green signal, but if the
desired output is in RGsB
format regardless of the input
signal, set the SYNC ON
GREEN jumper (J2) to the
ON position. The default
position for J2 is OFF.
4 When do I
use the HV
PRES
Jumper? If the desired output is in
RGBHV format, set the HV
PRES jumper (J5) to the ON
position. If the HV PRES
jumper is OFF then the
output signal may have
Composite Sync present on
the Horizontal Sync
connector.
