Cresnet® Hub
6-segment Cresnet hub For Cresnet networks with more than 20 devices No programming required

The CNXHUB is a 6-segment Cresnet hub designed to facilitate the configuration of large Cresnet networks. Cresnet is the communications backbone for Crestron touchpanels, keypads, lighting dimmers, and many other devices. This flexible 4-wire bus normally supports approximately 20 Cresnet devices and 3000 feet of Cresnet wiring without requiring a hub.

Larger systems are easily enabled by adding the CNXHUB. The CNXHUB features 6 isolated Cresnet segments, each supporting another 20 devices, allowing for systems of approximately 120 devices total. More hubs may be added to allow up to a maximum potential of 252 devices.*

The CNXHUB may be rack-mounted using the optional ST-RMK rack mount kit (sold separately).

Key Features: 
  • 6-segment Cresnet hub
  • For Cresnet networks with more than 20 devices
  • No programming required
  • 1/2-space rack-mountable

Technical notes: 

The actual number of possible devices per segment and per network may vary depending upon the length and geometry of network wiring, and the power requirements of every device. A general rule of thumb suggests approximately 20 devices, an aggregate of 3000 feet of cable, and up to a 75 Watt load per segment (wiring and devices permitting). In any case, 252 is the maximum number of possible devices on a complete Cresnet network. Contact Crestron True Blue Support for further design assistance.
