Product Manual — Doc. 9227A RMC4 • 3
Modular Programming Architecture
The RMC4 is designed to run a single program out of the box. The optional modular
programming architecture (MPA)add-on allows the RMC4 to run up to ten programs
simultaneously.1Programmers can develop and run independent, device-specific programs,
enabling each program to be optimized for a specific function and allowing for changes to be
made to one program without affecting the whole system.
Onboard Control Ports
Through a full complement of onboard control ports, the RMC4 can be integrated with a wide
variety of audio, video, lighting, motorized shades, thermostats, door locks, sensors, security
systems, and other equipment.
lEthernet provides an interface for connecting to the building network and controlling
Crestron AV switchers, audio processors, power controllers, and other IP controllable
equipment.
lCresnet® network connectivity provides support for Crestron lighting dimmers, motorized
shades, sensors, thermostats, keypads, and more.2
lOnboard RS-232, IR, relay, and digital input control ports enable direct integration with all
types of third-party equipment.
Expanded connectivity can be provided to the RMC4 via Crestron control port expansion
modules,Ethernet to Cresnet bridges,wired Ethernet I/O extenders, or Wi-Fi® network I/O
extenders (all sold separately).
Crestron Fusion Room Monitoring and Scheduling
Crestron Fusion provides an integrated platform for creating smart buildings that save energy
and enhance worker productivity. As part of a complete managed network in a corporate
enterprise, college campus, convention center, or any other facility, the RMC4 works with
Crestron Fusion to enable remote scheduling, monitoring, and control of rooms and technology
from a central help desk or mobile app. It also enables organizations to reduce energy
consumption by tracking real-time usage and automating control of AV, lighting, shades, and
HVAC. For more information about Crestron Fusion, visit www.crestron.com/fusion.
XiOCloud Provisioning and Management
4-Series control systems leverage the power and flexibility of XiO Cloud services, enabling users
to remotely provision, monitor, and manage Crestron devices across an enterprise network. XiO
Cloud can be used to configure and load programs to the control system before it is received,
making the control system fully functional as soon as it is connected to the network. XiO Cloud is
built on the Microsoft® Azure® software platform and utilizes Microsoft's industry leading Azure
IoT Hub technology. XiO Cloud enables installers and IT managers to deploy and manage
thousands of devices in the time it previously took to manage just one. Unlike other virtual
machine based cloud solutions, Azure services provide unlimited scalability to suit the ever
growing needs of an enterprise. For more information, visit www.crestron.com/xiocloud.

.AVFramework Software
The RMC4 provides native support for the .AVFramework™ software program. .AV Framework
software is a web-based management solution that is used to deploy scalable Crestron®
enterprise room solutions without requiring any programming. For more information on the
capabilities supported by .AV Framework, visit www.crestron.com/avframework.
Enhanced Enterprise-Grade Security
The RMC4 is an enterprise-class control processor that can be deployed across hundreds of
spaces and set up using a web browser, Crestron Toolbox™ software, or XiO Cloud. It employs
standard network security protocols, including 802.1X network access control, Active Directory®
service authentication, SSH, TLS, and HTTPS to ensure reliability and compliance with your
organization’s IT policies.
The RMC4 is configured to meet Crestron's enhanced security standards right out of the box.
The RMC4 ships with authentication enabled and requires that an administrator account be
created before access is granted to device configuration and control interfaces.
SNMPV3 Support
Built-in SNMP V3 support enables integration with third-party IT management software,
allowing network administrators to manage and control Crestron systems on the network in an
IT-friendly format.
BACnet Support
Native support for the BACnet communication protocol provides a direct interface to third-party
building management systems over Ethernet, simplifying integration with HVAC, security, and
other systems. Using BACnet, each system runs independently but communicates together on
one platform.1
Apple HomeKit Integration
The RMC4 supports integration with an Apple® HomeKit® technology system. Once the RMC4 is
paired with a HomeKit system via SIMPLprogramming, a Crestron TSR-310 can be used to
control supported Apple devices. Apairing QRcode is affixed to the RMC4 that makes it easy to
pair the control system directly to the Apple Home app.2
PoENetwork Powered
Using PoE technology, the RMC4 gets its operating power directly through the LAN wiring,
eliminating the need for a local power supply or dedicated power wiring. A PoE injector
(PWE-4803RU) simply connects in line with the LAN cable at a convenient location. Crestron PoE
switches (CEN-SW-POE-5 or CEN-SWPOE-16) may also be used to provide a total networking
solution with built-in PoE. All PoE injectors and switches are sold separately.

Product Manual — Doc. 9227A RMC4 • 5
Integrator Friendly Enclosure
The RMC4 features the Crestron IFE form factor, a compact Integrator Friendly Enclosure
design that fits almost anywhere and enables a variety of installation options. Its shape allows
the RMC4 and other IFE compliant devices to be stacked together. Using the included mounting
bracket, it can be fastened to a flat surface or snapped onto a standard DIN rail. Rack mount
and pole mount kits are also available (sold separately).
