QuickMedia™ Matrix Switcher/Mixer Crestron QM-MD5x1
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
upgrade the firmware of the MD5x1. 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 (Discontinued)
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 Crestron
2-Series Control System Reference Guide (Doc. 6256). These documents are
available from the Crestron website. Refer to the following diagram for a typical
connection diagram when uploading files.
NOTE: When connecting a PC to the QM-RMCRX, use a standard DB9 female-to-
female “null modem” cable. To connect to other control systems refer to the
Operations Guide included with the control system.
