CRESTRON
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.
