The Cresnet bus is the communications backbone for many Crestron touchpanels, keypads, expansion modules, tuners, and more. Cresnet is a simple, yet flexible 4-wire network that provides bidirectional communication and 24V power for Cresnet devices. With cable lengths up to 5000 feet, the Cresnet wiring topology allows almost limitless wiring configurations.
Overview
The Cresnet® bus is the communications backbone for many Crestron® keypads, lighting controllers, shade motors, sensors, and other devices. Cresnet is a simple, yet flexible 4-wire network that provides bidirectional communication and 24VDC power for Cresnet devices. Cresnet allows for both homerun and daisy-chain wiring topologies, with cable lengths up to approximately 3000 feet (915 meters) per run.
Cresnet "High-Power" control cable features extra-large conductors for power and ground to support devices that draw a large amount of power over the Cresnet bus. Within a single non-plenum PVC jacket, CRESNET-HP-NP contains (1) 12 AWG pair for 24VDC and Ground, and (1) 22 AWG shielded twisted pair for control data.
