Cresnet Bus
Cresnet is the communications backbone for many Crestron keypads, lighting controls, shade motors, thermostats, sensors, and other devices that do not 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. 10W total Cresnet power is available to both subnets using PoE, which can be increased to 20W using PoE+. Adding one or two external 24VDC Cresnet power supplies enables up to 75W Cresnet power to either or each subnet depending on the configuration. 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.
Diagnostics Tools
The DIN-CENCN-2-POE provides a full set of diagnostic tools to help identify and resolve common control system problems caused by wiring faults, insufficient power, or too many devices. 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 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.
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. The unit may be powered by either PoE/PoE+ or 24VDC Cresnet power, or both simultaneously.
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.
