The 4‑Series Control System, International (MC4‑I) provides a secure, high‑performance, cost-effective control processor and interface. Its small form factor and versatile mounting options makes it ideal for smaller systems such as single‑room media systems, small to medium‑sized homes and offices, and MDUs (multidwelling units). The MC4‑I includes a built‑in infiNET EX® and ER wireless gateway for acquiring wireless devices as well as numerous control ports for controlling wired devices.

4-Series Control Engine
4-Series control systems come equipped with an upgraded multicore CPU, delivering a sizable speed and performance increase compared to all Crestron 3‑Series® control processors. The improved performance allows 4-Series control systems to handle the increasing demands of an advanced automated system. Crestron 4-Series delivers a dynamic and secure control system platform capable of managing a room full of disparate technologies.

Reliable networking and IP control afford seamless integration with other systems and devices, with add-on control capability using Crestron touch screens, wireless remotes, and mobile device apps, as well as remote management through Crestron Fusion® software and the Crestron XiO Cloud™ service.

Modular Programming Architecture
The MC4‑I is designed to run a single program out of the box. The optional modular programming architecture add-on allows the MC4‑I to run up to ten programs simultaneously.1 Programmers 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 MC4‑I can be integrated with a wide variety of audio, video, lighting, motorized shades, thermostats, door locks, sensors, security systems, and other equipment.

• Gigabit Ethernet provides an interface for connecting to the building network and controlling Crestron AV switchers, audio processors, power controllers, and other IP controllable equipment.
• Cresnet® network connectivity provides support for Crestron lighting dimmers, motorized shades, sensors, thermostats, keypads, and more.
• Onboard RS‑232, IR, relay, and Versiport I/O control ports enable direct integration with all types of third‑party equipment.

Expanded connectivity can be provided to the MC4‑I 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).

Built-In Wireless Gateway
The MC4‑I also provides a built-in infiNET EX wireless gateway that allows wireless infiNET EX and ER (extended range) devices to be paired directly to the control system.

infiNET EX Technology
Integrated infiNET EX technology provides an easy and cost-effective way to control various functions using infiNET EX based wireless products. infiNET EX wireless technology provides 2‑way RF communications throughout a structure without the need for physical control wiring. Employing a 2.4 GHz mesh network topology, nearly every infiNET EX device on the network acts as an expander, relaying wireless commands between the gateway and all the other EX devices on the network to ensure that every command reaches its intended destination without disruption.2

Extended Range (ER) Technology
Crestron Extended Range (ER) wireless technology enables compatibility with certain Crestron wireless touch screens and handheld remotes. Crestron ER operates in the same 2.4 GHz spectrum as infiNET EX and is optimized specifically for use with wireless touch screen devices to ensure dependable bidirectional RF communications.

IR Wireless Option
When equipped with the optional CNXRMIRD IR Receiver, the MC4‑I affords a low-cost IR wireless control solution using a universal IR remote.

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 MC4‑I works with Crestron Fusion to
