ILT Shade Controller:
C2N-SSC-2
Introduction
Features and Functions
The Crestron®ILT Shade Controller, C2N-SSC-2, communicates with up
to two Somfy ILT Intelligent Shade Motors via a serial interface. In a
Crestron control system network (Cresnet®), the C2N-SSC-2 (herein
called Shade Controller) sets the position and the direction of motion of
each shade individually, with programmable settings for the upper and
lower limits of travel for each shade. Commands to move to a specific
location will position the shades relative to the full range of travel
between these upper and lower limits. Subsequent commands to move a
shade in the open or close direction activate shade movement until a limit
of travel is reached, until the command is de-activated, or until a stop
command is sent.
The Shade Controller can store and recall up to 20 shade presets.
Functional Summary
• Control up to two shades per Shade Controller
• Control position and direction of each shade individually
• Store and recall up to 20 presets per shade
• Connect via one 4-pin RJ-11 interface connector per shade
• Control shades in multi-unit installations individually, in
groups, all together, or any desired combination.

ILT Shade Controller Crestron C2N-SSC-2
2 •ILT Shade Controller: C2N-SSC-2 Operations & Installation Guide - DOC. 6318
The upper and lower limits of travel for each shade are set up at the time
of installation via the six pushbuttons on the face of the Shade Controller,
or via a touchpanel, and are stored internally to each ILT motor. Shade
presets, stored as values relative to the limits of travel, can be stored and
recalled locally in the Shade Controller.

Operations & Installation Guide - DOC. 6318 ILT Shade Controller: C2N-SSC-2 •5
Controls
The Shade Controller has six pushbuttons that are used to set the upper
and lower limits of travel for each shade. These limits are set at time of
installation and the values are stored in the ILT motor.
Shade Limit Control Pushbuttons
Pressing any one of the four outer pushbuttons puts the Shade Controller
into the limit-setting mode for the selected shade and upper or lower
limit. (Refer to “Setting Shade Limits and Direction of Travel” on page
13.)
Indicators
The only indicators on the Shade Controller are the three LEDs on the
face of the unit.
• The PWR LED (green) indicates the presence of +24V Cresnet
power.
• The NET LED (yellow) indicates an active Cresnet network
connection.
• The SETUP LED (red) indicates firmware upgrade, limit
setting, shade reversal, or the unit’s network ID setup activity.
− Flashes during firmware downloads
− On solid if in firmware loader mode (still needs application
firmware). Turns off after application firmware is loaded.
− On solid for twenty seconds if a shade 1/2 adjust
upper/lower limit button is pushed, putting the unit into
limit-setting mode.

6 •ILT Shade Controller: C2N-SSC-2 Operations & Installation Guide - DOC. 6318
− On for one second, then off when shade reversal is executed
from buttons on the unit.
SETUP LED and Pushbutton
The SETUP pushbutton and its associated LED are used for setup of the
unit’s network ID during the initial configuration of a Cresnet system or
when the device is being added/replaced. Refer to “Method B (Touch
Settable IDs)” on page 10 for detailed information.
Industry Compliance
As of the date of manufacture, the Shade Controllers have been tested
and found to comply with specifications for CE marking and standards
per EMC and Radiocommunications Compliance Labelling.
NOTE: This device complies with part 15 of the FCC rules. Operation is
subject to the following two conditions: (1) this device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
Setup
Network Wiring
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.
<http://www.crestron.com/dealer-tech_resources/power_calculator.asp>
NOTE: When installing network wiring, refer to the latest revision of the
wiring diagram(s) appropriate for your specific system configuration,

Crestron C2N-SSC-2 ILT Shade Controller
Operations & Installation Guide - DOC. 6318 ILT Shade Controller: C2N-SSC-2 •7
available from the Downloads | Product Manuals | Wiring Diagrams
section of the Crestron website (www.crestron.com).
NOTE: For larger networks (i.e., greater than 28 network devices), it
may be necessary to add a Cresnet Hub/Repeater (CNXHUB) to maintain
signal quality throughout the network. Also, for networks with lengthy
cable runs or varying types of network devices, it may be desirable to add
a hub/repeater after only 20 network devices.
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 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
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.
Wire Gauge Values
RESISTANCE (R) WIRE GAUGE

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.
Identity Code
Every equipment and user interface within the network requires a unique
identity code (Cresnet ID or Net ID). These codes are two-digit
hexadecimal numbers from 03 to FE. The Net ID of each unit must match
an ID code specified in the SIMPL Windows program. Refer to “Setting
the Net ID in Device Settings” on page 20 for details of the SIMPL
Windows procedure.
Refer to note
on page 27
f
or a
definition of
Viewport.
The Net ID of the C2N-SSC-2 has been factory set to 0C. The Net IDs of
multiple Shade Controllers in the same system must be unique. Net IDs are
changed from a personal computer (PC) via the Crestron Viewport.
NOTE: For detailed information on establishing communication between
the PC and control system, refer to “Communication Settings” on page
27. If communication cannot be established, refer to the
“Troubleshooting Communications” section in the latest version of the
2-Series Control System Reference Guide (Doc. 6256), which is
available from the Downloads | Product Manuals section of the Crestron
website (www.crestron.com). For other control systems, refer to the
respective Operations Guide.
There are two different methods—Method A or Method B—for setting
the Shade Controller Net IDs:
Method A (Cresnet address-settable ID), described on the next page,
applies to all Shade Controllers in a Cresnet system. This method

Crestron C2N-SSC-2 ILT Shade Controller
Operations & Installation Guide - DOC. 6318 ILT Shade Controller: C2N-SSC-2 •9
requires that a single Shade Controller be the only network device
connected to the control system.
Method B (Touch Settable IDs), which begins on page 10, applies to
Shade Controllers in a Cresnet system with 2-Series control system
upgrade file (CUZ) version 3.008 or later. These upgrades enable Touch
Settable ID (TSID) functionality, which makes it possible for the control
system to recognize a network device via its serial number, which is
stored in the device’s memory. This method does not require that any
devices be disconnected from the network; Net IDs may be set with the
entire Cresnet system intact.
Use the appropriate method to set the Shade Controller Net ID.
Method A (Cresnet address-settable ID)
1. Ensure that the Shade Controller is the only device connected
to the control system.
2. Open the Crestron Viewport.
3. From the Viewport menu, select Functions | Set Network ID.
The software checks the baud rate and then opens the "Set
Network ID" window.
4. In the "Set Network ID" window, select the C2N-SSC-2 from
the Current Network Devices text window.
5. Select the new Net ID for the Shade Controller from the
Choose the new network ID for the selected device (Hex): text
box.
6. Click Set ID to initiate the change. This will display the "ID
command has been sent" window.
7. In the "Command Complete" window, click OK.
8. In the Current Network Devices text window, verify the new
Net ID code.
9. In the "Set Network ID" window, click Close.
NOTE: The new Net ID code may also be verified by selecting
Diagnostics | Report Network Devices in the Viewport (alternately,
select F4).
10. Repeat this procedure for each Shade Controller to be added
to the system.

Method B (Touch Settable IDs)
Before using this method, you should have a list of all current network
devices and their Net IDs, to avoid assigning duplicate IDs.
Set Net ID via D3 Pro or SystemBuilder
Version 1.0 of this program includes procedures that enable setting the
Net ID. Refer to the extensive help information provided with the
software file for instructions. (For a brief description of the D3 Pro
program, refer to “Programming with Crestron SystemBuilder or D3 Pro”
on page 18.)
Set Net ID by TSID
These procedures are for TSID-enabled network devices during the initial
configuration of a Cresnet system or when such devices are being
added/replaced.
1. Ensure that all Shade Controllers are connected to the control
system.
2. Open the Crestron Viewport version 3.35 or later.
3. From the Viewport menu, select Functions | Assign Cresnet
ID by Serial Number. The “Set Net ID by TSID” window
appears. The window is first displayed with the data fields
empty.
• When you click on the Search for Touch Settable
Devices button, the system searches the network and lists
all TSID-enabled devices found, as shown in the figure on
the next page.
• This information is similar to the report produced by
pressing F4 (Report Network Devices); the first eight
digits of each line constitute the TSID number
(hexadecimal form of the serial number).

4. As you enter either the serial number or TSID number of the
device that requires a change, the corresponding TSID or
serial number automatically appears in its appropriate field.
The listing should show the device’s current Cresnet ID.
CAUTION: This function does not prevent you from setting duplicate
IDs. Be sure to check current assignments before entering the desired
Cresnet ID number.
5. Enter the Cresnet ID that the device should be set to and click
OK.
Serial Number to TSID Conversion
This utility is useful in a case where there are multiple devices of the
same type on a network, you need to locate a particular one, you know

Crestron C2N-SSC-2 ILT Shade Controller
Operations & Installation Guide - DOC. 6318 ILT Shade Controller: C2N-SSC-2 •13
Overview
Installation consists of mounting the Shade Controller (using either the
Dual Lock fastener or screws, as desired) in a location that is out of
casual reach, but within fifty feet of the shade(s) it controls; connecting a
Cresnet cable to the NET port; connecting the interface cable(s) from the
shade(s) to the RJ-11 port(s), and setting the upper and lower limits of
travel for the shade(s).
1. Turn Cresnet system power OFF.
2. Connect the Cresnet cable with supplied mate to the Shade
Controller’s Cresnet port and the other end to the control
system.
3. Connect the modular cable from the shade(s) to the Shade
Controller RJ-11 port(s). If a longer modular cable is required,
fabricate using standard 4-wire modular cable with 4-pin
(4 body size) modular plugs.
− Invert the plugs on the same cable. When the plugs are
held side by side, the wires are in the same order (refer to
following graphic).
− Check that the connector is correctly crimped.
Setting Shade Limits and Direction of Travel
When an ILT shade is first installed, the limits of travel will normally
come “pinched” together so that the shade will not move up or down.
Limits and travel direction for an ILT shade are not set mechanically, but
are stored electronically in the shade motor itself. Limits of travel must
be set for each shade in order for the shade to operate properly. The six

ILT Shade Controller Crestron C2N-SSC-2
14 •ILT Shade Controller: C2N-SSC-2 Operations & Installation Guide - DOC. 6318
buttons on the Shade Controller are used to set these limits, as defined in
the following table. Shade limits can also be set using the C2N-SSC-2
symbol.
Shade Limit Control Pushbutton Functions

When not in limit-setting mode, hold button down for 10
seconds to reverse Shade 1 orientation. SETUP LED
gives confirming flash when reversal is executed.
Down Button (J) In limit-setting mode, moves shade down; sets limit on
release.
When not in limit-setting mode, hold button down for 10
seconds to reverse Shade 2 orientation. SETUP LED
gives confirming flash when reversal is executed.
To prevent inadvertent setting of very wide limits, continuous adjustment
is allowed for periods of twenty seconds. At the end of any 20 second
period, the limit-setting mode will automatically terminate, and an adjust
limit select button must be pushed to initiate additional limit settings. For
example, if an adjust limit select button is pressed and no other buttons
are pushed, the Shade Controller will remain in limit-setting mode for
twenty seconds. At the end of this period, the SETUP LED will go off to
indicate that limits are no longer ready to be adjusted. Similarly, if limits
are being adjusted and the up (K) or down (j) button is pushed and
held, the shade will stop moving after 20 seconds and the limit-setting
mode will be terminated. Pushing any of the six buttons during the
20-second limit period will start a new 20-second period.
NOTE: Set the upper limit before setting the lower limit.

Crestron C2N-SSC-2 ILT Shade Controller
Operations & Installation Guide - DOC. 6318 ILT Shade Controller: C2N-SSC-2 •15
NOTE: During the limit-setting procedures, if the shade moves opposite
to the selected direction, refer to the direction reversing procedures given
on the next page.
NOTE: Perform limit or travel direction settings for each shade
individually.
NOTE: Do not press other buttons or touchpanel controls while setting
shade limits. Doing so will terminate the limit-setting procedure.
The following procedures apply to either shade. It is not necessary to set
the limits for shade 1 before shade 2.
Setting Shade 1 Upper Limit:
Press the shade 1 adjust upper limit button. The SETUP LED should
illuminate. The Shade Controller is now ready to set the upper limit of
travel for shade 1. Use the up (K) and down (j) buttons to adjust the
upper limit position. The shade will roll in the direction selected until the
button is released or the 20-second, limit-setting period ends. Upon
release of the button, the upper limit of travel will be stored in the ILT
shade. If necessary, repeat the procedure until the shade is correctly
positioned.
Setting Shade 1 Lower Limit:
Press the shade 1 adjust lower limit button for shade 1. The SETUP LED
should illuminate. The Shade Controller is now ready to set the lower
limit of travel for shade 1. Use the up (K) and down (j) buttons to
adjust the lower limit position. The shade will roll in the direction
selected until the button is released. Upon release of the button, the lower
limit of travel will be stored in the ILT shade. If necessary, repeat the
procedure until the shade is correctly positioned.
Limit-setting Verification:
It is recommended that both the upper and lower limits be verified after
the initial setup. First, verify that the shade is not in limit-setting mode by
confirming that the SETUP LED is not on. Push and hold the shade 1
adjust upper limit button for at least five seconds. Shade 1 will roll and
stop at the upper limit of travel. Push and hold the shade 1 adjust lower
limit button for at least five seconds. Shade 1 will roll and stop at the
lower limit of travel.

Reversing the Direction of Travel for a Shade
Whether a shade rolls up or down when a particular button is pushed
depends on the orientation of the shade during installation as well as how
the shade material is mounted to the cylinder. If the installer finds that the
shade moves opposite to the direction required, the direction of travel can
be reversed as follows:
For shade 1, verify that the unit is not in limit-setting mode (SETUP LED
is not illuminated), and then press and hold the up (K) button for at least
10 seconds. The SETUP LED will give a confirming flash. The direction
of travel for shade 1 has now been reversed.
For shade 2, verify that the unit is not in limit-setting mode (SETUP LED
is not illuminated), and then press and hold the down (j) button for at
least 10 seconds. The SETUP LED will give a confirming flash. The
direction of travel for shade 2 has now been reversed.
NOTE: Perform shade reversals on one shade at a time.
NOTE: After a reversal, it is necessary to re-adjust the limits since the
reversal process again pinches the upper and lower limits together so that
the shade cannot move.
