•  Cresnet 4-Channel Digital Volume Control: C2N-VEQ4 

NOTE:  Crestron recommends that you use the latest software and that each device 
contains the latest firmware to take advantage of the most recently released features. 
Please check the Crestron website (

versions of software and firmware. New users are required to register to obtain access 
to this site. 

Assuming a PC is properly connected to the entire system, Crestron programming 
software allows the programmer to upload programs and projects after their 
development to the system and network devices. However, there are times when the 
files for the program and projects are compiled and not uploaded. Instead, compiled 
files may be distributed from programmers to installers, from Crestron to dealers, etc. 
Even firmware upgrades are available from the Crestron website as new features are 
developed after product releases. In those instances, one has the option to upload via 
the programming software or to upload and upgrade via the Crestron Viewport.  

NOTE: The Crestron Viewport is available as a pull-down command from SIMPL 
Windows and VT Pro-e (Tools | Viewport) or as a standalone utility. The Viewport 
utility accomplishes multiple system tasks, primarily via an RS-232 or TCP/IP 
connection between the control system and a PC. It is used to observe system 
processes, upload new operating systems and firmware, change system and network 
parameters, and communicate with network device consoles and touchpanels, among 
many other tasks. Viewport can also function as a terminal emulator for generic file 
transfer. All of these functions are accessed through the commands and options in the 
Viewport menus. Therefore, for its effectiveness as a support and diagnostic tool, the 
Crestron Viewport may be preferred over development tools when uploading 
programs and projects.  

The following sections define how one would upload a SIMPL Windows program or 
upgrade the firmware of the C2N-VEQ4. However, before attempting to upload or 
upgrade, it is necessary to establish communications.  

NOTE:  For laptops and other PCs without a built-in RS-232 port, Crestron 
recommends the use of PCMCIA cards, rather than USB-to-serial adapters. If a USB-
to-serial adapter must be used, Crestron has tested the following devices with good 
results: 
 
 

Belkin (large model) F5U103 

 

I/O Gear GUC232A (discontinued) 

 

Keyspan USA-19QW (discontinued) 

 
Other models, even from the same manufacturer, may not yield the same results. 

The procedure in this section provides details for RS-232 communication between the 
PC and the control system. If TCP/IP communication is preferred, consult the latest 
version of the Crestron e-Control Reference Guide (Doc. 6052) or the respective 
Operations Guide for the control system. These documents are available from the 
Crestron website. Refer to the following figure for a typical connection diagram when 
uploading files.
