Uploading and Upgrading
Assuming a PC is properly connected to the entire system, Crestron programming
software allows the programmer to upload programs and projects to the system and
touchpanel 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 Viewport.
NOTE: The Crestron 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-DAP8RC. However, before attempting to upload
or upgrade, it is necessary to establish communications.
Communication Settings
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
Keyspan USA-19QW
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 2-Series 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 Downloads | Product Manuals section of the Crestron website
(www.crestron.com). Refer to the figure on the next page for a typical connection
diagram when uploading files.
NOTE: Use a standard DB9 male to female “straight-through” cable.
