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 AV4 provides a modular programming architecture that allows the AV4 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) to handle multiple
touch screens, gateways, AV components, and other devices. Each port also supports PoE+ using
the optional PW-5430DUS power supply. Automatic configuration of the entire subnet is
performed by the AV4, 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 AV4 can be integrated with audio,
video, lighting, motorized shades, thermostats, door locks, sensors, security systems, and other
equipment.1
lGigabit Ethernet 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.

Product Manual — Doc. 8559B 4-Series™ Control Systems • 5

AppleHomeKit Integration
The CP4N supports integration with an Apple® HomeKit® technology system. Once the CP4N 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 CP4N that makes it easy to
pair the control system directly to the Apple Home app.2
Notes:
1. A BACnet and IP license is required. A free license is available to support up to 50 BACnet objects on a single
4-Series control system. Support for more than 50 BACnet objects requires the purchase of one
SW-3SERIES-BACNET-50+ license. The CP4N supports a maximum of 1000 BACnet objects when dedicated for
BACnet use only. Actual capabilities are contingent upon the overall program size and complexity. To obtain the
license, visit www.crestron.com/bacnetlicense.
2. This feature is only available when using the TSR-310. Other Crestron touch screens, handheld remotes, and
keypads are not supported. For these interfaces, traditional IR or CEC control must be used to control supported
Apple devices.
