Communication Settings - Crestron C2N-RTHS Operations & Installation Manual

Remote Temperature/Humidity Sensor
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 upgrade the firmware of the
C2N-RTHS. 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:
NOTE: Results may vary depending on the computer being used. 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 Crestron website. Refer
to the figure on the next page for a typical connection diagram when
uploading files.
