Lutron®Keypad: CNWM-LU12
Description
Functional Description
The Lutron®Keypad, CNWM-LU12, is a 12 button keypad that is part of the
Crestron Home™ total control system. It features a faceplate and buttons that match
the style and colors of Lutron’s GRAFIK EYE ™ or Homeworks™ systems. The
CNWM-LU12 is a standard Cresnet device, may be programmed as desired using
SIMPL™ Windows, and does not require a ST-LT interface module.
The CNWM-LU12 is used instead of large banks of switches and/or dimmers and is
designed for wall-mounting into a 1-gang electrical box (recommended 2.5” depth).
The removable faceplate of the keypad can be customized to match a home’s paint
colors, wall coverings, or décor. All faceplates include custom engraving to label
button functions. Refer to the latest version of the Cresnet Engraving Worksheet for
the CNWM-LU12 (Doc. 5842) for engraving directions. Contact Crestron customer
support for further instructions.
The keypad has 12 functionally identical buttons and 10 of the buttons have
associated light emitting diodes (LEDs) for user feedback indicators. All buttons are
momentary switches and provide digital inputs to the Cresnet system. The
illumination of the LEDs, which are independently addressable, is programmed by
SIMPL Windows.
Physical Description
The CNWM-LU12 keypad is shown on the next page. Each keypad has 12 buttons
with the top 10 buttons are associated with LEDs for feedback indicators. The
buttons and LEDs, are arranged numerically from left to right, top to bottom.
The keypad consists of three major assemblies. The faceplate assembly contains a
removable, paintable faceplate and a faceplate frame that is attached to the button
assembly. The button assembly consists of a switch assembly with momentary
contact closure switches and a circuit board with an external ground wire. The third
assembly is the Crestron system adapter. This supplies Cresnet communications with
the keypad buttons and LEDs.
At the rear of the keypad is the Cresnet 4-wire, male connector (standard Cresnet
network port labeled 24 Y Z G). The connector provides the Cresnet 24VDC
operating power and communications to the keypad.

Setup
Network Wiring
NOTE: If making category 5 wire connections, refer to the latest revision of the
Cresnet Mini Network Cat 5 Interconnect Drawing (Doc. 5819). The document can
be obtained from the Downloads page (CABLES and MANUALS Libraries) of
Crestron’s website (www.crestron.com). Search for the CAT5.PDF file.
When calculating the wire gauge for a particular Cresnet run, the length of the run
and the load factor of each network unit to be connected must be taken into
consideration. If Cresnet units are to be daisy-chained on the run, the load factor of
each unit to be daisy-chained must be added together to determine the load factor of
the entire chain. If the unit is a home-run from a Crestron system power supply
network port, the load factor of that unit is the load factor of the entire run. The
length of the run in feet and the load factor 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 = Resistance (refer to next table).
L = Length of run (or chain) in feet.
LF = Load factor of entire run (or chain).
R < L x LF
40,000 Where:
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 table below:

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, always twist the ends of the incoming
wire and outgoing wire which share a pin on the network connector. After twisting
the ends, tin the twisted connection with solder. Apply solder only to the ends of the
twisted wires. Avoid tinning too far up the wires or the end becomes brittle. After
tinning the twisted ends, insert the tinned connection into the Cresnet connector and
tighten the retaining screw. Repeat the procedure for the other three conductors.

Keypad Installation
After the Cresnet network wiring has been installed, the CNWM-LU12 is installed
into a standard, 1-gang electrical box. The only tools required are a small flat-tip and
a Phillips tip screwdriver. To install the keypad, perform the following procedure:
NOTE: The CNWM-LU12 may be installed in any orientation. This procedure
assumes that the keypad will be installed vertically with the two square buttons
toward the bottom.
CAUTION: The connectors of the Crestron system adapter are offset (not centered)
in the mounting bracket. If the system adapter becomes separated from the button
assembly, first check the button assembly pins for straightness. Position the adapter
so that the mounting bracket holes align with the assembly mounting holes, and
CAREFULLY push the button assembly and adapter together.
1. Make sure that the Cresnet system power is turned OFF.
CAUTION: The CNWM-LU12 faceplate is a two-piece assembly and is shipped
with the faceplate installed onto the faceplate frame. To install the keypad, the
faceplate must first be separated from the frame. To avoid damage during the next
step, do not use excessive force when prying the faceplate away from the frame.
2. Using a small flat-tip screwdriver or your fingers, pry the top or bottom
of the faceplate away from the frame until the retaining tabs disengage.
Tilt the faceplate outward and the tabs on the opposite edge will
release. Separate the faceplate from the frame.
3. At the electrical box, connect the GREEN ground wire of the keypad
to the ground wire of the electrical box. (If the electrical box is metal
and does not have a ground wire, attach the keypad ground wire to the
electrical box.)
4. Connect the Cresnet connector to the rear of the keypad system adapter.
5. Make sure the two square buttons of the keypad are oriented as desired
and position the keypad into the electrical box.
CAUTION: Excess wire that is pinched between the keypad and electrical box
could short-out. Make sure that all excess wire is completely inside the electrical box
and not between the box and the keypad.
6. Using the Phillips tip screwdriver and the supplied Phillips screws,
mount the keypad to the electrical box.
7. Make sure that the two square holes of the faceplate are aligned with
the square buttons. Holding the faceplate at a slight angle, position the
top or bottom of the faceplate onto the faceplate frame. Apply pressure
to the opposite edge of the faceplate until the retaining tabs engage onto
the frame.
8. Turn Cresnet system power ON.

Identity Code
Every equipment and user interface within the Cresnet network requires a unique
identity code (NET ID). These codes are recognized by a two-digit hexadecimal
number from 03 to FE. The NET ID of the keypad must match an ID code specified
in the SIMPL Windows program. The NET ID of the CNWM-LU12 is factory set to
4E. The NET IDs of multiple keypads must all be unique and changed from a PC via
VisionTools™ Pro (VT Pro) or SIMPL Windows.
NOTE: VT Pro is a Windows compatible software package for creating Crestron
touchpanel screen designs.
The method for changing the unit’s NET ID is identical regardless of the software
chosen. Attach one of the keypads to the control system (verify that the software is
running) and complete the following steps to change the NET ID:
1. Disconnect all Cresnet devices from the control system, except for the
keypad that needs to have its NET ID changed.
2. Select Tools | Viewport to open the “Crestron Viewport” dialog box.
3. Select Functions | Set Network ID. The software checks the baud rate
and then opens the “Set Network ID” dialog box.
4. In the dialog box, highlight the keypad.
5. The NET ID of the keypad appears in the box below the list. Use the
scroll arrow to assign another NET ID.
6. When the assigned NET ID appears, select the Set ID button to initiate
the change.
7. The software responds with a successful message to confirm the
changed NET ID.
8. To verify this procedure, select Diagnostics | Report Network
Devices. Confirm that the keypad has a new NET ID code.
9. Reconnect other Cresnet devices that were disconnected in step 1.
Programming with SIMPL™ Windows
SIMPL (Symbol Intensive Master Programming Language) is an easy-to-use
programming language that is completely integrated and compatible with all
Crestron system hardware. The objects that are used in SIMPL Windows are called
symbols. SIMPL Windows offers drag and drop functionality in a familiar Windows
environment.
SIMPL Windows is Crestron Electronics' software for programming Crestron control
systems. It provides a well-designed graphical environment with a number of
workspaces (i.e., windows) in which a programmer can select, configure, program,
test, and monitor a Crestron control system.
The next two sections describe a CNWM-LU12 within a SIMPL Windows program.
The first section details the SIMPL symbol and the second section describes how an
example program works by using a textual description and a block diagram.
NOTE: The following descriptions assume that the reader has knowledge of SIMPL
Windows. If not, refer to the extensive help information provided with the software.

How the Example Program Works
NOTE: For purposes of the following block diagram, the Grey-Btn and White-Btn
outputs of the CNWM-LU12 symbol have been rearranged for clarity. Refer to
“CNWM-LU12 Symbol” above for the correct location of the outputs.
NOTE: There is no need to recreate the example SIMPL Windows program. The
program is available from the Software Downloads page (EXAMPLES Library) of
Crestron’s website (www.crestron.com). Search for CNWMLU12.SMW. New users
are required to register in order to obtain access to the FTP site.
The example SIMPL program for the CNWM-LU12 is shown on the next page as a
block diagram. Signal lamp 1 is input to a CNECI-4A for lighting on/off control and
feedback is provided to the CNWM-LU12. The remaining press2 through press10
outputs are used for additional lighting and/or drape control. In this example, signals
volume up and volume dn are used to adjust the volume of an audio device through
a CNXVTC-3. No feedback is provided to the CNWM-LU12 for audio adjustments.
