The PAC2 is a professional dual bus control system designed to serve as the central processor for Crestron Green Light™ systems. Fast performance, rigorous construction, and extreme flexibility provide a truly powerful automation solution for today's most demanding residential and commercial environments.

2-Series Control System
Built upon Crestron's reliable 2-Series control engine, the PAC2 is extensively programmable using Crestron's suite of powerful development software and vast database of drivers and software modules. The PAC2 works seamlessly with Crestron's entire line of lighting dimmers and shade controls, keypads and touchpanels, thermostats, wireless gateways, control cards, and expansion modules.

Whole House Integration
The PAC2 provides for the integration of non-Crestron devices and subsystems through a host of control interfaces. Eight isolated relays and eight I/O Versiports are built in to accommodate motion sensors, contactors, door strikes, and other low-voltage controls. Additional relays, I/O ports, RS-232, RS-422, RS-485, IR, and MIDI interfaces can be added by installing up to two Y-Bus control cards. Crestron also offers a full line of expansion modules to facilitate the placement of serial COM ports, relays, DTMF interfaces, and shade controllers at any location throughout a residence or commercial facility.

Modular Enclosure Installation
The PAC2 mounts in any CAEN or CAENIB automation enclosure and connects directly to the CLX-Series lighting modules. 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. With 32 separate Cresnet ports, the PAC2 provides extensive connectivity for numerous Cresnet devices on multiple homeruns. Its built-in Cresnet hub provides 8 isolated segments, each supporting 3000 feet of cabling and approximately 20 Cresnet devices. The Cresnet ports are arranged into 4 separate power groups providing a clean, flexible 24 Volt DC power distribution solution utilizing internal or external power supplies as needed.

Ethernet and e-Control®
A choice of single or dual-port Ethernet cards 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 PAC2'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.

The PAC2's onboard NAT (Network Address Translator) acts as a firewall and router to facilitate the configuration of a private control LAN for Crestron touchpanels and other Ethernet devices, with a single-point connection to the client's LAN (Dual-port Ethernet card required).

Backup Processor
For applications demanding ultimate reliability, a second backup PAC2 may be employed. An internal watchdog circuit constantly monitors the PAC2's processor, transferring control of the complete system in the event of a failure. An override input is also provided to allow an external contact closure to bypass the PAC2 and activate a preset override state in each connected lighting module.

Memory Expansion
A memory card slot allows for easy expansion of the PAC2's internal memory using any Type II Compact Flash memory card up to 4 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.
