Crestron C2N-SDC-DC Shade & Drape DC Motor Controller
Shade & Drape DC Motor Controller:
C2N-SDC-DC
Introduction
Features & Functions
The Crestron C2N-SDC-DC is a shade and drape DC motor control
Cresnet
motors that drive shades and drapes. The C2N-SDC-DC is specifically
designed for the Cresnet control network and functions as part of a
complete Crestron control/automation system. Power for the shade
motors is derived from the Cresnet +24 VDC supply. Two 2-pin terminal
connectors are provided for + drive and – drive for each motor.
Functional Summary
The C2N-SDC-DC is designed to fit inside and mount to a 2-gang wall
box or 4 x 4 x 1.5 inch electrical box, where input power for the two
shade or drape motors is derived from Cresnet.
®
slave module designed to control two 2-wire bi-directional DC
• Controls two 24 VDC shade or drape motors individually or
simultaneously (30 W maximum)
• The C2N-SDC-DC mounts on a standard 2-gang or
4-inch square electrical box
• Four manual pushbutton controls are provided on the faceplate
Two 2-pin terminal blocks for motor connections can accommodate
30 AWG to 12 AWG wires.
A hardware interlock prevents the motors from being driven in both
directions simultaneously. In addition, the firmware implements a

lockout timer that shuts the motor off for a brief time before allowing the
motor to reverse direction. Additional control is available via Cresnet.
Four pushbuttons on the face of the unit allow the motors to be activated
without Cresnet control, which is particularly useful when operating the
unit locally during installation.

1. Does not include power for the motors. For example, add 10 Watts for
each Somfy LT28B shade motor. Three Watts are consumed by the
C2N-SDC-DC when the motors are not operating. Motor loads may be
connected to the C2N-SDC-DC up to the available power remaining on
the Crestron power supply. Crestron recommends that the available power
be de-rated by a factor of two to allow for the inrush motor current that

for the C2N-SDC-DC and associated motors is recommended.

Physical Description
The C2N-SDC-DC is a mountable plate with electronic components
attached to the rear side. The front side of the plate is labeled and
includes; three LEDs that indicate the unit’s status, one Cresnet
connector, two connectors for motor control, and all local motor controls.

Setup
Network Wiring
CAUTION: In order to ensure optimum performance over the full range
of your installation topology, Crestron Certified Wire, and only Crestron
Certified Wire, should be used. Failure to do so may incur additional
charges if support is required to identify performance deficiencies as a
result of using improper wire.
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 (http://www.crestron.com/calculators)
help calculate how much power is needed for the system.
to
NOTE: When installing network wiring, refer to the latest revision of
the wiring diagram(s) appropriate for your specific system configuration,
available from the Crestron website.
When calculating the wire gauge for a particular Cresnet run, the length
of the run and the Cresnet power usage of each network unit to be
connected must be taken into consideration. If 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 a 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 length of the run in feet
and the Cresnet power usage of the run should be used in the following
resistance equation to calculate the value on the right side of the
equation.
Resistance Equation
R <
40,000
L x P
Where:
R = Resistance (refer to the following table).
L = Length of run (or chain) in feet.
P = Cresnet power usage of entire run (or chain).

The required wire gauge should be chosen such that the resistance value
is less than the value calculated in the resistance equation. Refer to the
following table.

NOTE: All 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.
NOTE: 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.
NOTE: For larger networks (i.e., greater than 28 network devices), it
may become necessary to add a Cresnet Hub/Repeater (CNXHUB) to
maintain signal quality throughout the network. Also, for networks with
lengthy cable runs, it may be necessary to add a Hub/Repeater after only
20 devices.
