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.  It provides a well-designed graphical environment with a number 
of workspaces (i.e., windows) in which a programmer can select, configure, 
program, test, and monitor a Crestron control system.  

The next two subsections describe a sample SIMPL Windows program that utilizes 
the CNXVGA. The first subsection details how the sample program works with a 
textual description. The second subsection provides a broad description of how to 
actually create the SIMPL Windows program.  

NOTE:  The following description assumes that the reader has knowledge of 
SIMPL Windows. If not, please refer to the extensive help information provided 
with the software.  

NOTE:  There is no need to recreate the sample touchpanel or SIMPL Windows 
program. A copy of each is available from Crestron’s ControlCD (version 5.1 and 
later). Search for or CNXVGA2.VTP and CNXVGA2.SMW projects in the SIMPL 
Windows Example Base directory.  

NOTE:  SIMPL Windows v1.21.04 or later and CNXVGA firmware v1.26 or 
higher are required to program a control system containing the newly improved 
CNXVGA symbol. This new CNXVGA symbol must replace the CNXVGA symbol 
in programs created with earlier versions. The out-dated CNXVGA symbol appears 
in updated programs with a “CNXVGA OLD” heading. Keep in mind that inputs 
and outputs to the old and new CNXVGA symbol are not directly compatible and 
older programs may need to be reworked.  

The example program demonstrates how to use the CNXVGA and its associated 
functions within a system.  The core program is based around the network definition 
for the CNXVGA.  The following is a brief explanation of the CNXVGA network 
definition implementation. 

RGB, Video, Out_disable:  The RGB and Video are used to select which input 
source should be displayed on the output using a momentary activation on the input.  
Out_disable can be used to “mute” the output and is typically driven off a toggle. 

In_Adj, Out_Adj:  The input adjust allows the user to position and size each RGB 
image to best fit within the boundaries of the display. The Out_Adj is not typically 
needed when you use the CNXVGA to display on either the VT-3500 or VT-3500L 
touchpanels. If some other display device is used, it may be necessary to define the 
visible area of the screen. The Out_Adj allows adjustments to be made. All 
incoming signals and presets stored after making the adjustment will conform to the
