Crestron® DIN Rail 3-Series® Automation Processor with infiNET EX® and ER wireless gateway

Get to know this product.

The DIN-AP3MEX is a Crestron® 3-Series Control System® designed for DIN rail mounting applications. It includes a built-in infiNET EX® & ER wireless gateway, high-speed Ethernet, Cresnet®, and BACnet™/IP support. DIN rail mounting affords a very space-efficient, cost-effective, and modular solution for configuring complete automation systems using the DIN-AP3MEX along with additional Crestron and third-party DIN rail mountable devices.

The Crestron® DIN-AP3MEX is a 3-Series Control System® designed for DIN rail mounting applications. Built-in infiNET EX® and ER wireless technology makes the DIN-AP3MEX ideal for all types of lighting, shading, AV, and climate control applications wherever a reliable wireless control solution is preferred. Wired Cresnet® and Ethernet communication is also supported. Featuring the 3-Series® control engine, the DIN-AP3MEX forms the core of any modern networked home or commercial building, managing and integrating all the disparate technologies throughout your facility to make life easier, greener, more productive, and more enjoyable.

DIN Rail Mounting

    The DIN-AP3MEX is designed to snap onto a standard DIN rail for installation in a wall mount enclosure (Crestron DIN-EN series or similar) or on a wall panel. DIN rail mounting affords a very space-efficient, cost-effective, and modular solution for configuring complete automation systems using the DIN-AP3MEX along with additional Crestron and third-party DIN rail mountable devices.

3-Series® Control Systems

    Today's commercial buildings and custom homes comprise more technology than ever before, and all these systems need to be networked, managed, and controlled in fundamentally new ways. The IP based 3-Series platform is engineered from the ground up to deliver a network-grade server appliance capable of faithfully handling everything from lighting and AV system control to total building management.

    3-Series embodies a distinctively robust, dynamic, and secure platform to elevate your system designs to higher levels of performance and reliability. Compared to other control systems, Crestron 3-Series provides a pronounced increase in processing power and speed with more memory, rock solid networking and IP control, and a unique modular programming architecture.

Modular Programming Architecture

    Designed for enhanced scalability, the DIN-AP3MEX affords high-speed, real-time multi-tasking to seamlessly run multiple programs simultaneously. This exclusive modular programming architecture lets programmers independently develop and run device-specific programs for lighting, shades, HVAC, security, AV, etc., allowing for the optimization of each program, and allowing changes to be made to one program without affecting the whole. Even as your system grows, processing resources can easily be shifted from one 3-Series processor to another without rewriting any code. The end benefit is dramatically simplified upgradability with minimal downtime, whether implementing changes on site or remotely via the network.

Robust Ethernet & IP Control

    IP technology is the heart of 3-Series, so it should be no surprise that its networking abilities are second to none. High-speed Ethernet connectivity enables integration with IP-controllable devices and allows the DIN-AP3MEX to be part of a larger managed control network. Whether residing on a sensitive corporate LAN, a home network, or accessing the Internet through a cable modem, the DIN-AP3MEX provides secure, reliable interconnectivity with IP-enabled touch screens, computers, mobile devices, video displays, media servers, security systems, lighting, HVAC, and other equipment — whether on premises or across the globe.

Control Apps & XPanel

    Years ago, Crestron pioneered the world's first IP-based control system unleashing vast new possibilities for controlling, monitoring, and managing integrated systems over a LAN, WAN, and the Internet. Today, Crestron offers more ways than ever to control your world the way you want. Using a computer, smartphone, or tablet device, Crestron lets you control anything in your home or workplace from anywhere in the world.

    Native to every 3-Series control system, Crestron XPanel technology transforms any laptop or desktop computer into a virtual Crestron touch screen. Crestron control apps deliver the Crestron touch screen experience to iPhone®, iPad®, and Android™ devices, letting you safely monitor and control your entire residence or commercial facility using the one device that goes with you everywhere.

Crestron Fusion® Cloud

    Crestron Fusion Cloud provides an integrated platform for creating truly smart buildings that save energy, enhance worker productivity, and prolong the life-span of valuable equipment. As part of a complete managed network in a corporate enterprise, college campus, convention center, or any other facility, the DIN-AP3MEX works integrally with Crestron Fusion Cloud to enable remote scheduling, monitoring, and control of rooms and technology from a central help desk. It also enables organizations to reduce energy consumption by tracking real-time usage and automating control of lighting, shades, and HVAC.

Astronomical Time Clock Feature

    Scheduled events may be programmed on the DIN-AP3MEX according to an astronomical time clock. As a result, events can be set to occur at specific times or at an offset from sunrise or sunset.

SNMP Support

    Built-in SNMP 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.

infiNET EX® Wireless Control

    Integrated infiNET EX technology provides an extremely easy and cost-effective way to add control of lighting, shades, room temperature, door locks, and other functions using our complete line of infiNET EX based wireless products. Adding infiNET EX wireless keypads and remotes enables complete, customizable control over everything from any room. Perfect for existing structures and rentals, infiNET EX affords ultra-reliable 2-way wireless communications throughout a home or business without the need for physical control wiring.

“ER” Extended Range RF 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 specifically optimized for use with wireless touch screen devices to ensure robust and dependable bidirectional RF communications.


    Cresnet provides a dependable network wiring solution for Crestron keypads, lighting controls, shade motors, thermostats, occupancy sensors, and other devices that don't require the higher speed of Ethernet or the wireless communication of infiNET EX. The Cresnet bus offers easy wiring and configuration, carrying bidirectional communication and 24VDC power to each device over a simple 4-conductor cable. To assist with troubleshooting, the DIN-AP3MEX includes our patent-pending Network Analyzer which continuously monitors the integrity of the Cresnet network for wiring faults, marginal performance, and other errors.

    The DIN-AP3MEX 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 the DIN-HUB Cresnet Distribution Hub or DIN-CENCN-2 Ethernet to Cresnet Bridge. Connectivity for multiple homeruns can be facilitated using one or more DIN-BLOCK Cresnet Distribution Blocks. Additionally, at least one DIN-PWS50 Cresnet Power Supply is required to power the DIN-AP3MEX and any connected Cresnet devices.


    Native support for the BACnet/IP communication protocol provides a direct interface to third-party building management systems over Ethernet, simplifying integration with HVAC, security, fire & life safety, voice & data, lighting, shades, and other systems. Using BACnet/IP, each system runs independently with the ability to communicate together on one platform for a truly smart building.
