        DIN-CENCN-2-POE

        Ethernet to Cresnet® Network Bridge with PoE

        Works with a Crestron® Control System® to maximize Cresnet® network reliability and performance. Enables Cresnet data over high-speed Ethernet and features two isolated Cresnet subnets, built-in network diagnostics, and versatile power management.

        The DIN-CENCN-2-POE is an Ethernet to Cresnet® Network Bridge that works with a Crestron® Control System® to maximize the reliability and robustness of the Cresnet network. It offers a more sophisticated solution than a Cresnet block or hub, providing two isolated subnets and built-in diagnostics, plus versatile power distribution options and a convenient DIN rail form factor.

        NOTE: The DIN-CENCN-2-POE is not compatible with Crestron 2-Series control systems or earlier.

        The Cresnet Bus
        Cresnet is the communications backbone for many Crestron keypads, lighting controls, shade motors, thermostats, sensors, and other devices that don’t require the higher speed of Ethernet. It provides a dependable and flexible wiring solution, allowing multiple devices to be wired together in parallel using both home-run and daisy-chain topologies. The Cresnet bus distributes bidirectional data communication and 24VDC power to each device over a single 4-conductor cable.

        Ethernet to Cresnet Bridge
        Adding Ethernet to Cresnet bridges to a Crestron Control System enables the distribution of Cresnet over high-speed Ethernet. The increased bandwidth afforded by Ethernet reduces latency for overall improved speed and performance. Wiring distances can be extended easily while potentially reducing the overall wiring requirements by leveraging existing LAN infrastructure in any facility. One or more bridges can be deployed on a single control system, and they can even be addressed by more than one control system, affording incredible flexibility in system design and functionality.

        Dual Cresnet Subnets
        The DIN-CENCN-2-POE provides two isolated subnets. Each subnet behaves as a Cresnet Server with its own unique address space. A maximum of 20 Cresnet devices is supported per subnet, and each subnet furnishes six Cresnet connectors for easy termination of multiple lines. Crestron recommends a maximum aggregate cable length of 1500 feet (457 meters) per subnet.

        Cresnet Power Distribution
        Proper power distribution is key to a reliable Cresnet network. To facilitate proper powering, the DIN-CENCN-2-POE offers versatile, scalable power management using PoE or 24VDC. 10 W total Cresnet power is available to both subnets using PoE, which can be increased to 20 W using PoE+. Adding one or two external 24VDC Cresnet power supplies enables up to 75 W Cresnet power to either or each subnet depending on the configuration. For more details, refer to the “Power” section of the specifications.
        The DIN-CENCN-2-POE configures itself automatically based on the power source(s) connected. Built-in protection intelligently monitors the load and wiring conditions on each subnet, and shuts down power to either subnet in case of an overload, wiring fault, or power supply failure. If such an error occurs, only the subnet with the error is shut down, leaving the other subnet fully operable.

        Diagnostics Tools
        Many common control system problems are caused by wiring faults, insufficient power, or too many devices. The latter is resolved by increasing bandwidth using Ethernet and limiting the number of devices that can be connected to each subnet.
        For the other issues, the DIN-CENCN-2-POE provides a full set of diagnostic tools to help identify and resolve them easily.
        From the unit’s front panel, an installer can press the TEST button and observe the LED indicators to see if there are any error codes. This allows wiring problems to be identified before ever powering up the control system. More complete details can be viewed and analyzed using a web browser or Crestron Toolbox™ software.
        In a functioning system, sporadically occurring errors caused by cut or faulty wires, disconnected devices, or failed power supplies can be reported to the control system in real-time to provide error notifications via a touch screen, mobile device, email, or text message. For commercial enterprise applications, SNMP, and Crestron Fusion® Cloud applications are also supported. Insertion of an SD memory card (not included) enables logging of Cresnet activity and errors, making it easier to diagnose intermittent issues that cannot be duplicated on demand.

        Power over Ethernet
        Using PoE+ technology, the DIN-CENCN-2-POE gets its operating power through the LAN wiring from a PoE or PoE+ power source (PWE-4803RU, CEN-SW-POE-5, or CEN-SWPOE-16, sold separately). Alternately, the unit can be powered by 24VDC Cresnet power. Refer to the “Power” section of the specifications for more details.

        DIN Rail Mounting
        The DIN-CENCN-2-POE is designed to snap onto a standard 35 mm DIN rail for installation in a wall mount DIN-EN series enclosure or on any flat surface. DIN rail mounting affords a very space-efficient, cost-effective, and modular solution for configuring complete control systems using a Crestron control system along with additional Crestron and third-party DIN rail mountable devices.
