Video output connectors — Connect up to four RGBHV, RGBS,
4
RGsB, RsGsBs, component video, S-video, high resolution
monochrome video, or composite video output devices, such as
data projectors or data monitors, to these female BNC
connectors.
DIP switches — This 2-bank DIP switch allows selection of high
5
and low video gain and sync level.
Video Gain: Set this switch to high or low while viewing the
displayed image to set the level that provides the best
picture quality.
X1.3 — Applies gain for long cable runs (up to 200 feet
HI using Extron Mini HR cable).
X1.3
LOW X1 — Eliminates gain for short cable runs.
X1
Sync Level: Set this switch to adjust the sync portion of the
video with the sync signal.
HI — Applies 5 volts peak-to-peak.
LOW — Applies 3 volts peak-to-peak.
Adjustments apply to all four outputs.

Input and Output connections

RGB and component video inputs — Connect an RGBHV,
RGBS, RGsB, RsGsBs component video, S-video, composite
video source to these BNC connectors.

When making connections, ensure that inputs and
outputs are using the same signal (e.g., S-video BNCs
are connected on both input and output connectors).

Operation and Troubleshooting

Connect the power cords and turn on the displays (projectors or
monitors), the DA, and the input device (computer). The image
should appear on the screens.
If the image does not appear or is not displayed correctly
1. Ensure that all devices are plugged in.
2. Make sure that each device is receiving power. The DA's
front and rear panel power LEDs indicate if the DA is
receiving power
3. Check the cabling and make adjustments as needed.
