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).

* 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.
