2.1.5 RGB/YPrPb Output
Connect this to the Display System. This could be a Projector, High Definition TV, or
Monitor. The VLS-2000 may be configured to connect to RGB or YPrPb Display
Systems, with any sync requirement (HV, Sync-On-Y, Sync-On-Green, Tri-Level, or
Composite). For connection to equipment with Phono or BNC connectors, breakout
cables are available. Consult your dealer.
2.1.6 Power Input
The VLS-2000 is provided with a universal AC power supply. This will automatically
sense line voltage from 90 Volts AC to 264 Volts AC, at line frequency from 47 Hz to
63 Hz. This allows connections anywhere in the world. Plug the small power plug
from the power supply into the Power input jack, and connect the black line cord from
the power supply to the wall outlet.
2.2 Output Setup
It is important to set up the VLS-2000 output prior to turning on your display system. Some
projectors and monitors can be damaged if run for any length of time with the wrong scan rates
or improper sync signals. Section 3 of this manual shows how to set up operating parameters.
There are four output settings which need to be set up for your display device
2.2.1 Output:
This must be set up to match your display device. If it has input connections labeled
“R”, “G”, and “B”, or a 15 pin plug labeled “RGB”, set this setting to RGB. If your
connections are labeled “Y”, “Pr”, and “Pb”, set this to YPrPb.
2.2.2 Scaling
This must be set to match the resolution of your projector. Typically, it would be set to
the maximum resolution of your projector. 640x480, 800x600, and 1024x768 are
common settings for projectors and monitors designed for computer use. 480p, 720p,
and 960p are common resolutions for High definition TVs and projectors, and
1365x1k is a common size for new D-ILA projectors.
2.2.3 Screen
This should match the shape of your screen and/or projector, measured as a ratio of
width to height. Set it to 4:3 for computer or TV shaped screens, and to 16:9 for wide
screens intended for movie viewing. This setting allows the VLS-2000 to perform any
necessary scaling to make any size image fit your display.
2.2.4 Sync
The sync type must be determined by looking at your display device manual.
Generally, devices which connect with a 15 pin VGA style cable, or 5 separate cables
labeled R, G, B, H, and V will use the H-V Pos or H-V Neg setting. Three wire
connections to RGB monitors will need the RGsB setting. Three wire connections to
Component input monitors will need the YsPrPb setting. Some newer High
Definition monitors require Tr-Level sync require the TriLevel setting, and if you
