CNXHUB

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.[1]

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.[2]

1. Crestron advises a maximum total of 20 Cresnet devices and a maximum aggregate cable length of 3000 feet (914 meters) per hub segment. A Cresnet hub does not account for the distribution of Cresnet power. Additional equipment and wiring may be required for proper powering of each device on the network.
