QuickMedia™ Receiver/Processor Crestron
QM-RMCRX
Serial Connection
Connect the COM B port on the QM-RMCRX
control system to one of the COM ports (usually
COM 1) on the PC. The QM-RMCRX requires the
use of a null-modem RS-232 cable with DB9
female connectors on both ends. Most c
available cables are acceptable; they should have at
least five pins for transmit, receive, ground, and
hardware handshaking (pins 2, 3, 5, 7 and 8).

processor is configured as a master, but has no program loaded. In this w

any special steps to initially configure the processor.
NOTE:
The Viewport utility performs multiple system tasks, primarily via an
d
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 accesse
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.
