CRESTRON
These two BNC connectors connect to the two VIDEO port connectors of the VT-
3500L for composite or S-Video. These connectors should not be used if the
CNXVGA is connected to the VT-3500.
The load impedance on both BNC connectors is 75 ohms. The “COMP Y” output is
a luminance or composite signal, 1.0 Vp-p. The “C” output is the chrominance
signal, 0.28 Vp-p.
NOTE:
The video output is configured for S-Video from the factory to provide the
best result from the scan converter. Make sure the VT-3500 or VT-3500L that is
connected is configured to accept S-Video through the on-screen setup menus.
TIP:
If the application requires the video output to be composite rather than S-
Video, a single internal jumper can configure the CNXVGA to output the scan-
converted image as a composite signal. Refer to “Special Applications” on page 5
for details.
NET
There is an 8-position, 8-pin RJ45 connector on one side of the CNXVGA that
connects to the VT-3500 directly. This connector should not be used if the
CNXVGA is connected to the VT-3500L.
There are two 4-pin network connectors on the opposing side. The dual network
connectors are pass through. One connector connects to the CRESNET control
network. The other connects to the VT-3500L (if this VideoTouch configuration is
used) or to other Crestron equipment (if the VT-3500 is connected and daisy
chaining additional devices is necessary).
CNXVGA Indicators
A number of indicators are provided on the top panel of the CNXVGA. Refer to the
descriptions of each below.
PWR (Power)
This LED illuminates when power is applied to the CNXVGA.
NET
This LED illuminates when there is network activity involving the CNXVGA.
VIDEO
This LED illuminates when the internal multiplexer is set to display the composite or
S-Video source.
RGB
This LED illuminates when the internal multiplexer is set to display the RGB source.
LOCAL
This LED illuminates when the CNXVGA is under local control.
CNXVGA Local Button
A single recessed button is used to cycle between RGB and video.
