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.
NOTE: Firmware for the CNRFGWA is not upgradable in the field.
Before attempting to upload, 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 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 below for a typical connection diagram
when uploading files.
Note: Use a standard DB9 male to female “straight-through” cable.
