The Ethernet to Cresnet Bridge (DIN-CENCN-2-POE) works with any Crestron 3-Series 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.

The Cresnet Bus
Cresnet is the communications backbone for many Crestron keypads, lighting controls, shade motors, thermostats, occupancy 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 one or more Ethernet to Cresnet bridges to a 3-Series 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. And, by leveraging existing LAN infrastructure in any facility, wiring distances can be extended easily while potentially reducing the overall wiring requirements. 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 master 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.[1]

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.Ten Watts total Cresnet power is available to both subnets using PoE, which can be increased to 20 Watts using PoE+.
