Crestron Green Light™ DIN Rail
Cresnet® Distribution Hub:
DIN-HUB
Introduction
The DIN-HUB is a DIN rail-mounted Cresnet® hub designed to facilitate the configuration of large Cresnet networks. DIN rail mounting enables modular installation alongside Crestron® DIN Rail lighting and automation control modules and other third party DIN rail mountable devices.
Features and Functions
•Three-segment Cresnet hub
•Recommended for large Cresnet networks*
•Configurable power distribution
•No programming required
•6M wide DIN rail mounting
*Use of a DIN-HUB is advised whenever the number of Cresnet devices on a network is greater than 20 or when the combined total length of Cresnet cable exceeds 914 meters (3000 feet).

Three-Segment Cresnet Hub
Cresnet is the communications backbone for Crestron lighting modules, wall box dimmers, shade controllers, thermostats, keypads, touchpanels, and many other devices. This flexible 4-wire bus normally supports approximately 20 Cresnet devices without requiring a hub. Larger systems are easily enabled by adding the DIN-HUB. The DIN-HUB features three isolated Cresnet segments, each supporting an additional 20 devices, allowing for systems of approximately 80 devices total (including the “host” segment). More hubs may be added to allow up to a maximum potential of 252 devices.*
*The actual number of possible devices per segment and per network may vary depending upon the amount of data traffic, 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 914 meters (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 (www.crestron.com/true_blue_support) for further design assistance.
Cresnet Power Distribution
In addition to data, Cresnet carries 24 Volts DC for powering the devices connected to it. The DIN-HUB provides an easy way to manage the distribution of power for a complete Cresnet network. Each segment can be configured to receive its power from the “host” power source or from another power supply. Separate power supplies may be dedicated to each segment, or a single supply can be shared amongst multiple segments as needed. Each segment supports up to 75 Watts.
DIN Rail Installation
The DIN-HUB is designed to snap onto a standard DIN rail for installation in a wall mount enclosure or mounted on a wall panel. Wiring connections are made using detachable screw terminals positioned along the top and bottom, clearly accessible from the front for easy installation and servicing. Diagnostic indicators are positioned on the center front panel. When installed in an enclosure utilizing 45 mm cutouts, the DIN-HUB’s front panel stays visible while the connections are concealed.
