Sale price$1,650.00


The DIN-AP4 is a secure, high‑performance control processor with a powerful 4-Series™ control engine designed specifically for DIN rail mounting applications. The DIN-AP4 is designed to integrate and automate technology within any modern networked home, commercial building, or government facility. DIN rail mounting provides a space‑efficient, cost‑effective, and modular solution for configuring complete automation systems using the DIN-AP4 along with additional Crestron and third‑party DIN rail mountable 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 Crestron 3‑Series® control processors. The improved performance allows 4-Series control systems to handle the increasing demands of an advanced automated system.

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 DIN-AP4 provides a modular programming architecture for running 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.

Through a full complement of onboard control ports, the DIN-AP4 can be integrated with a wide variety of audio, video, lighting, motorized shades, thermostats, door locks, sensors, security systems, and other equipment.

  • 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.

Cresnet Network
Cresnet provides a dependable network wiring solution with simple configuration, carrying bidirectional communication and 24 VDC power to each connected device over a 4‑conductor cable. The DIN-AP4 includes a pair of Cresnet master ports (paralleled) capable of supporting approximately 20 typical devices. Larger systems with more than 20 devices can be handled by adding a DIN‑HUB Cresnet distribution hub or a DIN‑CENCN‑2 Ethernet to Cresnet bridge. Connectivity for multiple wiring runs can be facilitated using one or more DIN‑BLOCK Cresnet distribution blocks (all sold separately).

Crestron Fusion Room Monitoring and Scheduling
As part of a complete managed network, the DIN-AP4 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.

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

Enhanced Enterprise-Grade Security
The DIN-AP4 is an enterprise‑class control processor that can be deployed across hundreds of spaces and set up easily using a web browser, Crestron Toolbox™ software, or Crestron 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 DIN-AP4 is configured to meet Crestron's enhanced security standards right out of the box. The DIN-AP4 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 DIN-AP4 supports integration with an Apple® HomeKit® technology system. Once the DIN-AP4 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 DIN-AP4 that makes it easy to pair the control system directly to the Apple Home app.2

Versatile Power Options
The DIN-AP4 can be powered using a 24 VDC power pack (PW‑2407WUL or equivalent, sold separately) or via PoE (Power over Ethernet). Using PoE technology, the DIN-AP4 gets its operating power directly through the LAN 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.

DIN Rail Mounting
The DIN-AP4 is designed to attach to a standard DIN rail for installation in a wall mount enclosure (Crestron DIN‑EN series or similar) or on a wall panel as part of a complete DIN rail automation system.
