DIN Rail 2-Series Automation Processor

  • 2-Series control engine
  • MMC memory expansion card slot
  • Cresnet port - master/slave selectable
  • EMerge Alliance® Compatible

The DIN-AP2 is a 2-Series control processor designed for small to medium-sized lighting and automation applications. DIN rail mounting enables modular installation alongside Crestron DIN Rail lighting and automation control modules and other third-party DIN rail mountable devices.

2-Series Processor
Built upon Crestron's reliable 2-Series control engine, the DIN-AP2 is extensively programmable using Crestron's suite of powerful development software and vast database of drivers and software modules. The DIN-AP2 works seamlessly with Crestron's entire line of lighting dimmers and shade controls, keypads and touchpanels, thermostats, wireless gateways, and expansion modules.

DIN Rail Installation
The DIN-AP2 is designed to snap onto a standard DIN rail for installation in a wall mount enclosure or mounted on a wall panel. Wiring connections are made using detachable screw terminals positioned along the top and bottom, clearly accessible from the front for easy installation and servicing. All setup controls and connections are positioned on the center front panel. When installed in an enclosure utilizing 45 mm cutouts, the DIN-AP2's front panel stays accessible while all other connections are concealed.

System Integration
The DIN-AP2 provides for the integration of non-Crestron devices and subsystems through a host of control interfaces. Four isolated relays and eight Versiport I/O ports are built in to accommodate all kinds of sensors, contactors, door strikes, and other low-voltage controls. Two bidirectional RS-232 COM ports and four IR/serial ports allow for the integration of everything from simple shade controllers to advanced security systems. Additional interfaces and controllers can be added easily using Crestron's DIN Rail series lighting and automation modules.

Cresnet is the communications backbone for Crestron lighting modules, wall box dimmers, shade controllers, thermostats, keypads, touchpanels, and many other devices. This flexible 4-wire bus streamlines the wiring of a complete Crestron system. The DIN-AP2 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. 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-AP2 and any connected Cresnet devices.

Ethernet and e-Control®2
Built-in 10/100 Ethernet facilitates secure high-speed network connectivity, enabling extensive capabilities for remote system maintenance and control, and providing an interface to other Crestron control systems. Native features include a built-in email client to report system troubles and other functions to the owner or service company via instant email notification. An onboard Web server provides the foundation for Crestron's exclusive e-Control 2 Xpanel technology, providing secure IP-based remote control.

RoomView® and SNMP—For large facilities utilizing multiple DIN-AP2's and other control systems, Crestron's exclusive RoomView Help Desk software delivers a comprehensive solution for remote monitoring and asset management. Also, built-in SNMP support enables similar capability using third-party network management software, allowing full control and monitoring from the IT Help Desk or NOC in a format that's familiar to IT personnel.

Memory Expansion
A memory card slot allows for easy expansion of the DIN-AP2's internal memory using an MMC-compatible memory card up to 2 GB.

D3 Pro™ Software
Crestron D3 Pro software eliminates the need for custom programming, providing a complete design, development, and documentation solution for the lighting professional.
