The PRO4 is a secure, high‑performance control processor with a powerful 4-Series control engine and an enhanced feature set, including a front panel color LCD display, built-in control card expansion slots, and dedicated control subnet ports. The PRO4 is designed to integrate and automate technology within any modern networked home, commercial building, or government facility. The isolated control subnet port provides a Gigabit Ethernet LAN dedicated to Crestron 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 XiO Cloud® service.
Modular Programming Architecture
The PRO4 provides a modular programming architecture that allows it to run up to ten programs simultaneously. 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.
Dedicated Control Subnet
The Crestron Control Subnet is a Gigabit Ethernet network dedicated to Crestron devices. Via the Control Subnet ports, an installer can connect up to four touch screens or wireless gateways or can add Crestron PoE switches (CEN‑SW‑POE‑5 or CEN‑SWPOE‑16, both sold separately) to handle multiple touch screens, gateways, AV components, and other devices. Each port also supports PoE+ using the optional PW-5430DUS power supply (sold separately). Auto‑configuration of the entire subnet is performed by the PRO4, discovering each device and assigning IP addresses without any extra effort from the installer.1
A separate LAN port provides a single-point connection to the local network, requiring only one IP address for the entire control system. The LAN port allows for interconnectivity between devices on the local subnet and other devices, systems, servers, and WAN/internet connections outside the local subnet. For sensitive applications that require heightened security, the entire Control Subnet can be isolated completely from the local network.
Onboard Control Ports
Through a full complement of onboard control ports, the PRO4 can be integrated with a wide variety of audio, video, lighting, motorized shades, thermostats, door locks, sensors, security systems, and other equipment.1
- 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/serial, relay, and Versiport I/O control ports enable direct integration with all types of third‑party equipment.
