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 a VT Pro-e project, or upgrade the firmware of the CNX-B12.
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 control system. If TCP/IP communication is
preferred, consult the latest version of the Crestron e-Control Reference
