The 4-Series Control System for Crestron Home™ OS, International (MC4‑R‑I) provides a secure, high‑performance, cost-effective control system with the embedded Crestron Home operating system. Its small form factor and versatile mounting options makes it ideal for smaller Crestron Home systems such as single-room systems, small to medium-sized homes, and MDUs (multidwelling units). The MC4‑R‑I comes equipped with a 4‑Series multicore CPU processor that delivers remarkable speed and performance while handling the demands of an advanced automated system.

The MC4‑R‑I is a perfect replacement for a PYNG-HUB processor when upgrading a smaller system from Crestron Pyng® OS to Crestron Home.

NOTE: For larger homes and systems that require additional processing power, refer instead to the CP4‑R 4‑Series Control Processor for Crestron Home™ OS.

Built-In Crestron Home OS
Crestron Home unlocks the full potential of a smart home. It provides dealers with the ability to deliver a sleek user interface that includes fluid dynamic room controls and new features such as support for multiple homes, favorites, custom access, room image customizations, and more.

Refer to www.crestron.com/crestronhome for more information about Crestron Home and for a list of supported Crestron and third‑party equipment.

Wired and Wireless Device Support
Through a full complement of onboard control ports, the MC4‑R‑I allows Crestron Home to integrate with a wide variety of audio, video, lighting, motorized shades, thermostats, door locks, sensors, security systems, and other equipment. The MC4‑R‑I also provides a built-in infiNET EX® wireless gateway that allows wireless devices to be paired directly to the control system and then added to the Crestron Home system1.

System expansion is made easy using the CEN‑IO series of wired Ethernet and Wi-Fi® network I/O extenders (sold separately), which provide additional COM (CEN‑IO‑COM‑102 and CEN‑IO‑COM‑202), digital input (CEN‑IO‑DIGIN‑104 and CEN‑IO‑DIGIN‑204), IR (CEN‑IO‑IR‑104 and CEN‑IO‑IR‑204), or relay (CEN‑IO‑RY‑104 and CEN‑IO‑RY‑204) ports for integration with all kinds of third‑party equipment.

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.

PoE Network Powered
Using PoE technology, the MC4‑R‑I 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.

NOTE: Ethernet speed is limited to 100 Mbps when using the PWE-4803RU.

Versatile Mounting Options
The MC4‑R‑I mounts conveniently to a wall, ceiling, or other flat surface. Its compact, surface-mountable form factor fits easily behind a flat panel display, beneath a tabletop, or inside other furniture, making it ideal for single-room systems. It can even be installed into an equipment rack using the included rack
