Crestron® Cresnet® Hub

At a Glance

Crestron® Cresnet® Hub with six isolated Cresnet segments and 20 Cresnet devices per segment support

Proposition 65 Warning for California Residents

Provides six isolated hub segments to facilitate the configuration of large Cresnet® networks.

The CNXHUB is a six-segment Cresnet® hub designed to facilitate the configuration of large Cresnet networks. A Cresnet hub is ordinarily required for any Cresnet network that has more than 20 devices or 3000 feet (914 meters) of cable.NOTE: For maximum Cresnet performance and reliability, use an Ethernet to Cresnet Bridge (DIN-CENCN-2 or DIN-CENCN-2-POE).

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.

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. A Cresnet hub 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” 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.
