Expanded Video Adapter: CNXVGA
Description
Functional Description
The CNXVGA is an expanded video graphic adapter (or scan converter) made for
use with Crestron’s VT-3500 and VT-3500L video touchpanels. With the addition of
a CNXVGA any VT-3500/L becomes a cost effective computer graphic or
multimedia touchpanel.
The CNXVGA accepts RGB video in standard DOS, VGA, SVGA, XGA, and MAC
formats (from 640 x 480 to 1024 x 768 resolution) and outputs either composite or
S-Video. Maximum rate with defined resolution is XGA at 72 Hz. Higher rates are
available at lower resolution. The unit works with RGBHV and RGBS.
The CNXVGA has network adjustable parameters for each video format identified.
Flash memory in the unit stores the parameters for up to 25 formats. A single
external recessed button is used to cycle between the RGB port and video port.
Physical Description
The CNXVGA, shown on the next page, is housed in a black enclosure with a silk-
screened top panel. The high density 15-pin female RGB IN, four coaxial cable ports
for VIDEO IN and VIDEO OUT, and an 8-position RJ45 (for VT-3500 only)
modular jack is located on one side of the unit. Two 4-pin network connectors are
located on the opposite side. Five LEDs are located on the top panel to provide the
unit’s status. Below the LEDs, there is a single button used for local control. At the
shorter sides of the CNXVGA, the enclosure extends to form feet at a right angle to
the side. There are three holes per foot for inserting screws when mounting to a VT-
3500L or stabilizing the device on a flat surface when connected to a VT-3500.

CNXVGA Ports
A number of ports are provided on the side panels of the CNXVGA. Refer to the
descriptions of each below.
RGB IN
This DB15 female connector accepts RGB video in standard (DOS, VGA, SVGA,
XGA) and MAC formats with resolution from 640 x 480 to 1024 x 768. Refer to the
pinout table below.

NC = Not Connected
These two BNC connectors connect to a video source for composite or S-Video.
Connect the “COMP Y” input to a luminance signal and the “C” input to a
chrominance signal of an external S-Video source. For composite video use the
“COMP Y”input only.
The input impedance on both BNC connectors is 75 ohms. The “COMP Y” input is
rated for a signal 1.0 Vp-p. The “C” input is rated for a signal 0.28 Vp-p.
VIDEO OUT

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.
