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.

Network Wiring
When wiring the Cresnet®network, consider the following:
• Use Crestron Certified Wire.
NOTE: Cresnet-HP wire cannot be used.
• Use Crestron power supplies for Crestron equipment.
• Provide sufficient power to the system.
CAUTION: Insufficient power can lead to unpredictable results
or damage to the equipment. Please use the Crestron Power
Calculator to help calculate how much power is needed for the
system (www.crestron.com/calculators).
For more details, refer to “Check Network Wiring” on page 14.
Installation
The DIN-HUB must be installed by a licensed electrician, in accordance
with all national and local codes.
CAUTION: This equipment is for indoor use only. Mount in a well
ventilated area. The ambient temperature must be 0º to 40º C
(32º to 104º F). The relative humidity must be 10% – 90%

DIN RAIL RELEASE
1. Place the top of the DIN-HUB’s rail mount over the top of the DIN
rail.
2. Tilt the bottom of the DIN-HUB toward the DIN rail until it snaps
into place.
NOTE: When mounting DIN rail products, it may be necessary to
use a flat-head screw driver to pull the DIN rail release tab while
snapping the device onto the DIN rail.
To remove the DIN-HUB from the DIN rail, use a small, flat object (i.e. a
flat-head screwdriver) to pull the DIN rail release tab and tilt the bottom
of the DIN-HUB away from the DIN rail.
NOTE: Certain third party DIN cabinets provide space for an
informational label between each DIN rail row. Crestron’s Engraver
software (version 4.0 or later) can generate appropriate labels for all
Crestron DIN rail products.

Check Network Wiring
Use the Right
Wire In order to ensure optimum performance over the full range of your
installation topology, Crestron Certified Wire and only Crestron Certified
Wire may be used. Failure to do so may incur additional charges if
support is required to identify performance deficiencies because of using
improper wire.
Calculate
Power CAUTION: Use only Crestron power supplies for Crestron equipment.
Failure to do so could cause equipment damage or void the Crestron
warranty.
CAUTION: Provide sufficient power to the system. Insufficient power
can lead to unpredictable results or damage to the equipment. Please use
the Crestron Power Calculator to help calculate how much power is
needed for the system (www.crestron.com/calculators).
When calculating the length of wire for a particular Cresnet run, the wire
gauge and the Cresnet power usage of each network unit to be connected
must be taken into consideration. Use Crestron Certified Wire only. If
14 •DIN Rail Cresnet Hub: DIN-HUB Operations & Installation Guide – DOC. 6671A

Crestron DIN-HUB DIN Rail Cresnet®Distribution Hub
Cresnet units are to be daisy-chained on the run, the Cresnet power usage
of each network unit to be daisy-chained must be added together to
determine the Cresnet power usage of the entire chain. If the unit is
home-run from a Crestron system power supply network port, the
Cresnet power usage of that unit is the Cresnet power usage of the entire
run. The wire gauge and the Cresnet power usage of the run should be
used in the following equation to calculate the cable length value on the
equation’s left side.
Cable Length Equation
L = Length of run (or chain) in feet
R = 6 Ohms (CrestronCertifiedWire:0.75 MM (18 AWG))
P = Cresnet power usage of entire run (or chain )
2
L < 40,000
R x P
Where:
Make sure the cable length value is less than the value calculated on the
right side of the equation. For example, a Cresnet run using 0.75mm2
(18 AWG) Crestron Certified Wire and drawing 20 watts should not have
a length of run more than 101 meters (333 feet). Cresnet-HP cannot be
used.
NOTE: All Crestron certified Cresnet wiring must consist of two
twisted pairs. One twisted pair is the +24V conductor and the GND
conductor and the other twisted pair is the Y conductor and the Z
conductor.
Strip and Tin
Wire When daisy-chaining Cresnet units, strip the ends of the wires carefully
to avoid nicking the conductors. Twist together the ends of the wires that
share a pin on the network connector and tin the twisted connection.
Apply solder only to the ends of the twisted wires. Avoid tinning too far
up the wires or the end becomes brittle. Insert the tinned connection into
the Cresnet connector and tighten the retaining screw. Repeat the
procedure for the other three conductors.
