        The PAC2M is a compact, low-cost alternative to the PAC2 designed for small lighting and automation applications. At half the size of a PAC2, the PAC2M is perfect for apartments and smaller homes as well as individual meeting rooms and lecture halls.

        2-Series Control System

        Built upon Crestron's reliable 2-Series control engine, the PAC2M is extensively programmable using Crestron's suite of powerful development software and vast database of drivers and software modules. The PAC2M works seamlessly with Crestron's entire line of lighting dimmers and shade controls, keypads and touchpanels, thermostats, wireless gateways, and expansion modules.

        System Integration

        The PAC2M provides for the integration of non-Crestron devices and subsystems through a host of control interfaces. Four isolated relays and four digital input ports are built in to accommodate motion sensors, contactors, door strikes, and other low-voltage controls. Additional relays, I/O ports, serial COM ports, DTMF interfaces, and shade controllers can be added using Crestron expansion modules at any location throughout a commercial or residential facility.

        Modular Enclosure Installation

        The PAC2M is designed to install in a CAEN or CAENIB automation enclosure and provide a direct bus to a cabinet full of CLX-Series lighting control modules. It is also suitable of surface mount installation without an enclosure where allowed. Every Crestron lighting system is completely modular and scalable, allowing virtually unlimited configuration and expansion flexibility.

        Cresnet® Distribution

        Cresnet is the communications backbone for Crestron lighting modules, wall box dimmers, thermostats, keypads, and many other devices. This flexible 4-wire bus streamlines the wiring of a complete Crestron lighting system. The PAC2M provides connectivity for numerous Cresnet devices on multiple homeruns via 8 separate Cresnet ports. Its built-in Cresnet hub provides 2 isolated segments, each supporting 3000 feet of cabling and approximately 20 Cresnet devices. The Cresnet ports are arranged into 2 separate power groups providing a clean, flexible 24 Volt DC power distribution solution. An external power supply is required (sold separately).

        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 PAC2M'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.


        An override input is provided to allow an external contact closure to bypass the PAC2M and activate a preset override state in each connected lighting module.

        Memory Expansion

        A memory card slot allows for easy expansion of the PAC2M's internal memory using any MMC-compatible memory card up to 1 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.
