CRESTRON
Special Applications
The CNXVGA ships preconfigured to convert all RGB input signals to an S-Video
output. Some applications require the RGB input signals to be converted to a
composite video output.
For example, consider an application where a computer image is provided to the
CNXVGA. A composite video output signal is required so that it can be sent to the
video switcher where the signal can be made available to multiple places as a video
source. The block diagram below represents the aforementioned application.

Changing the output format is easy; simply move the position of a single internal
jumper. Complete the following steps to remove the CNXVGA cover and
reconfigure the video output signal to provide composite video. The only tools
required are a Phillips tip screw driver and grounding strap.
CAUTION:
The CNXVGA contains electrostatic sensitive devices (ESD); observe
precautions for handling ESDs to avoid damaging the unit.
1. Place CNXVGA on a flat surface.
2. Remove four screws and four washers that secure cover to the unit.
