Cresnet® Bus

Cresnet is the communications backbone for many Crestron keypads, lighting controls, shade motors, thermostats, occupancy 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.

Six-Segment Cresnet Hub

Without a Cresnet hub, the Cresnet bus supports a maximum of 20 devices and a maximum aggregate cable length of 3000 ft (914 m). Adding a Cresnet hub improves reliability for larger networks. The CNXHUB divides the network into multiple isolated segments, each capable of supporting another 20 devices with 3000 ft (914 m) of additional cabling.

Under-Table or Rack-Mountable

The CNXHUB is housed in a compact metal enclosure that can be placed on a shelf, attached under a table, or mounted in a 19-inch equipment rack. Its 1RU half-width form factor allows it to fit in a single rack-space alongside a second CNXHUB or other 1RU half-width Crestron device.
