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.
CRESTRON CNXVGA Physical Views 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.
CRESTRON These two BNC connectors connect to the two VIDEO port connectors of the VT3500L 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.

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.

Preparation for Use Connections to the CNXVGA vary slightly depending on whether the unit is being used with a VT-3500 or VT-3500L. Refer to the two hookup diagrams after this paragraph. Other than making the power connection last, complete the connections in any order.
CRESTRON NOTE: When connecting the CNXVGA to the VT-3500L, it may be useful to add a right angle adapter (part number 351A505, BoMar or equivalent, not supplied) to the BNC connectors of the VT-3500L, labeled VIDEO. Doing so, may make installation of the unit into tight locations easier.
CRESTRON Identity Code Every equipment and user interface within the control system network requires a unique identity code (NET ID). These codes are recognized by a two-digit hexadecimal number from 03 to FE. The NET ID of each CNXVGA has been factory set to 38. If the application requires it, there are several ways to change the NET ID of a CNXVGA in the control system using the PC via VisionTools™ Pro or SIMPL™ Windows. Complete the following steps to change the NET ID. 1.
CRESTRON Programming with SIMPL™ Windows SIMPL (Symbol Intensive Master Programming Language) is an easy-to-use programming language that is completely integrated and compatible with all Crestron system hardware. The objects that are used in SIMPL are called symbols. SIMPL Windows offers drag and drop functionality in a familiar Windows® environment. SIMPL Windows is Crestron Electronics' software for programming Crestron control systems.
CRESTRON new output settings. For the adjustments to take place the CNXVGA must be in the RGB mode and one of these two inputs must be held high. Up, Down, Left, Right Width+, Width-, Height+, Height-, Save_Settings: These parameters only affect the selected aforementioned functions (either In_Adj or Out_Adj). These parameters make a single step adjustment for every positive transition on the corresponding input.
CRESTRON System View of VT-3500 in SIMPL Windows’ Configuration Manager As mentioned earlier, all CNXVGAs are factory set with the NET ID set to 38. However, in SIMPL™ Windows, the default can be changed while adding a CNXVGA to the control system. In the System Views area of the Configuration Manager, the CNXVGA NET ID can be altered in the “Device Settings” dialog box, shown below. To obtain the dialog box, right mouse click on the CNXVGA icon in the System Views area and select configure.
