QM-RMC
Introduction
Features and Functions
The QM-RMC is a low cost IP management tool to help facilities easily control
and monitor A/V devices. This powerful, compact control system enables serial,
IR, and Ethernet devices such as projectors, switchers, TVs, and other A/V
equipment to be controlled over IP networks. QM-RMC is an ideal solution for
colleges, universities, and other multi-room installations. It is a full-scale control
system with complete support of all Crestron e-Control® 2 and power
applications.
Functional Summary
• Powerful 2-Series processor, based on Motorola’s ColdFire®
technology, with non-volatile memory.
• Native e-mail client
• Supports DHCP, DNS and SSL (refer to the notes following this
summary).
®
• Supports XPanel IE/EXE/PDA control (Crestron e-Control
• Programmable logic via SIMPL Windows, including SIMPL+
• Flash memory and DRAM.
• Two bi-directional COM ports with built-in serial drivers for
controlling devices over RS-232.
• One IR port - compatible with Crestron ST-SPL IR-Splitter, for IRControl of up to five different devices, programmable via the hundreds
of IR device drivers available in the Crestron databases.
• Four digital input ports for direct connection of power sensors, pressure
sensors, door sensors, room occupancy sensor, etc.
• A 10/100 Ethernet LAN port with built-in Web server and support for
DHCP; and support for all Crestron e-Control power applications and
Crestron RoomView™ A/V facility monitoring and management
software.
• When used with Crestron RoomView™, provides remote power
control and management of A/V devices, including: monitoring lamp
life of projectors, device status to ensure proper equipment operations,
room occupancy, equipment use log, and device and room security.

NOTE: DHCP (Dynamic Host Configuration Protocol) is a network protocol
that enables a DHCP server to automatically assign an IP address to an
individual computer's TCP/IP stack software. DHCP assigns a number
dynamically from a defined range of numbers (i.e., a scope) configured for a
given network.
NOTE: DNS stands for Domain Name Service (or System). Its primary use is
to translate, or resolve, the IP number for a computer (e.g., 129.79.5.208) from
an alphanumeric name.
NOTE: SSL, or Secure Socket Layer, is the most commonly used protocol for
Web security. In addition to providing security for HTTP (Web hypertext)
transactions, SSL works with other TCP/IP standards such as IMAP mail and
LDAP directory access. For a security standard such as SSL to work, the
browser and the Web server must both be configured to use it.
The QM-RMC is a stand-alone processor with all of the capabilities of a 2Series processor, without the Cresnet
®
port. The QM-RMC is programmed with
SIMPL Windows and has a built-in web server, native email client, supports
DHCP and DNS, as well as SSL (Secure Socket Layer - Industry standard
network security native to all Crestron 2-Series control systems). Versatile
enough to operate as a standalone control system, the QM-RMC is also ideally
suited for integration with an MP2E, MC2E or the CP2E low-cost room control
solutions.
The QM-RMC provides a 10/100 Ethernet port with support for DHCP and a
built-in Web server, so users can control serial devices from any computer on
the LAN, WAN, or even the Internet. Create customized Web pages using
Crestron VisionTools
®
Pro-e software, eliminating the need for third-party Web
page design software.
®
In fact, the new Crestron e-Control
2 technology gives Web pages the same
look and feel as Crestron’s TPS ISYS® touchpanel pages, with almost zero
latency. This means you can add multi-mode buttons, gauges, sliders, subpages
and high-resolution graphics to your Web page projects, and the runtime
performance will be the same as with TPS touchpanels. Crestron e-Control 2
also generates standalone executables allowing users to launch from their
Windows® desktop, or Windows XP/Windows, CE StrongARM, XScale, Web
Tablet/Handheld PC, or Pocket PC 2002 PDA.
Some applications that QM-RMC can be used to monitor include: remote power
control/management of A/V devices, lamp life of projectors, device status to
ensure proper equipment operations, room occupancy, and room and/or device
security. It can also be used to remotely lock out projector/display controls from
unwanted users or to log equipment usage. Combined with the power of
Crestron RoomView
™
software, hundreds of rooms with QM-RMCs can be
centrally monitored as to the status of all the above-mentioned functions by
multiple AV-personnel using PC/laptops connected to their LAN/WAN/Internet.

Physical Description
The QM-RMC is housed in a black enclosure with labels on the front and rear
panels. On the front of the unit there are six LEDs for indicating the unit’s
current status, two LEDs on the LAN connector, and two reset buttons. All
connections, except for the Ethernet and power connections, are made on the
back of the unit. There are four rubber feet on the base of the unit for stability
and to prevent slippage. Refer to the physical views shown below.

SW-R
Pressing this button in combination with the HW-R button performs a system
restart without loading the program (refer to “Troubleshooting
Communications” on page 13). Press HW-R momentarily while pressing and
holding SW-R to reboot.
Pressing SW-R alone while the system is running restarts the program, and puts
the unit at a default IP address. COM B port becomes a remote console
connection.
PWR (Power)
This green LED illuminates when the unit is connected to and receives 12 VDC
power from an external power pack.
ACT (LAN)
This LED illuminates when the QM-RMC communicates with any device on the
network.

Memory
The QM-RMC has 36MB of built-in memory (non-volatile and volatile). The
total of 36MB is specified as follows: 4MB flash (non-volatile), 32MB SDRAM
(volatile), and 256KB NVRAM (battery backed up). Flash memory contains the
file system inside the 2-Series control engine. Non-volatile memory contains
information that is retained after the loss of electrical power. Volatile memory is
lost after a power failure. Refer to the following lists for a breakdown of
memory usage for program-related information stored in the unit.
