Uploading and Upgrading
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
