Example Program
An example program for the QM-TX is available from the “Example Program”
section of the Crestron website (http://www.crestron.com/exampleprograms).
Uploading and Upgrading
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
(http://www.crestron.com/updates) for the latest 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, projects and
firmware to the system and touchpanels after their development. 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 Installer’s Toolbox.
