Restart Box 
Depressing “6” from the MAIN MENU allows the user to restart the device. The 
program responds with the ‘DO YOU REALLY WANT TO RESTART THE 
DEVICE?’ message. Depress ’Y’ to restart or ‘N’ to abort the restart. Depress any 
key to return to the MAIN MENU.  
Upload Firmware 
Depressing “7” from the MAIN MENU allows the user to upload the latest firmware 
via the Serial connection. The program responds with the ‘READY FOR XMODEM 
TRANSFER’ message and then proceeds to upload the firmware. When the upload 
is complete, the program returns to the MAIN MENU.  
SIMPL™ Windows
 Programming 
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 a 
CEN-IO module. The first subsection details how the sample program works with a 
textual description and block diagram. 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 SIMPL Windows program. A 
similar copy of this program is available from Crestron’s ControlCD (version 5.2 
and later). Search for the CEN-IO.SMW project in the SIMPL Windows Example 
Base.  
How the Program Works 
A basic CEN-IO SIMPL program is shown below in block diagram form. This 
example demonstrates a two zone lighting system (ZONE 1 and ZONE 2) that 
utilizes a CT-3500 touchpanel as the user interface and a CEN-IO to control the 
lights.
