Source and Numeric Keypads:
CN-WP12F and CN-WP12N

Description

Functional Description

The Source and Numeric Keypads, CN-WP12F and CN-WP12N, are wall-mounted
user-interface devices designed to work with the CNX-PAD8 Professional Audio
Distribution Processor. The keypads are installed into the physical rooms of a building
to control the CNX-PAD8 and its audio source devices.

The CN-WP12F serves as the source keypad. It consists of six source selector buttons,
an ON/OFF button, a MUTE button, device transport control and volume control
buttons. The CN-WP12N is an optional numeric keypad that is used to expand the
capabilities of the source keypad. It contains a CLEAR button, an ENTER button, and
numeric digit buttons 0 through 9. The keypad is ideal for audio device functions such
as selecting a particular track number of a CD or a certain disc of a CD changer.

Both keypads are standard Cresnet devices and may be programmed as desired using
SIMPL Windows. In addition, a set of pre-programmed modules is available from
Crestron to facilitate easier programming of the keypads and the CNX-PAD8. These
modules are referred to as the CrestronHome Programming Kit and can be obtained
from the Downloads page (MACROS Library) of Crestron’s website
(www.crestron.com).

Physical Description

The CN-WP12F and CN-WP12N keypads are shown on the next page. Each keypad
has 12 buttons and on the CN-WP12F, the top eight buttons contain LEDs for user
feedback indicators. The SIMPL™ Windows program determines the state of the
indicators, either off, on, or flashing. The CN-WP12N has an LED for the ENTER
button only.

Network Wiring

NOTE: When making category 5 wire connections, refer to the latest revision of the
Cresnet Mini Network Cat 5 Interconnect Data Sheet (Doc. 5819).

When calculating the wire gauge for a particular network run, the length of the run
and the load factor of each network unit to be connected must be taken into
consideration. If network units are to be daisy-chained on the run, the load factor of
each network unit to be daisy-chained must be added together to determine the load
factor of the entire chain. If the network unit is a home-run from a Crestron system
power supply network port, the load factor of that network 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

Where:

R <

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 on the next page:

40,000

L x LF

R = Resistance (refer to next table).
L = Length of run (or chain) in feet.
LF = Load factor of entire run (or chain).

NOTE: All network 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 network 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 network connector and
tighten the retaining screw. Repeat the procedure for the other three network
conductors.

Keypad Installation

After the network wiring has been installed, the CN-WP12F and CN-WP12N are
installed into standard electrical switch boxes. Designer or decorator wall-plates (not
supplied) should be used to complete the mechanical installation.

Identity Code

Every equipment and user interface within the 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 IDs of the CN-WP12F and CN-WP12N
keypads are factory set to 4C and 48, respectively. 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 network devices from the control system, except for the

one keypad that needs to have its NET ID set.

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.

Operations Guide - DOC. 5788A Source and Numeric Keypads: CN-WP12F and CN-WP12N •• 7

Source and Numeric Keypads Crestron CN-WP12F and CN-WP12N

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 network 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 subsections describe a
sample SIMPL Windows program that utilizes the CN-WP12F and the CN-WP12N.

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.

NOTE: There is no need to recreate the sample SIMPL Windows program. The
latest CrestronHome Programming Kit CNHOME.ZIP can be obtained from the
Downloads page (MACROS Library) of Crestron’s website (www.crestron.com).
New users are required to register in order to obtain access to the FTP site.

How the Program Works

The Source and Numeric Keypads are fully customizable and can be programmed as
desired. However, the CrestronHome Programming Kit contains the necessary pre­programmed software to operate the CNX-PAD8 with the keypads. The kit contains
the SIMPL Windows program, the operational instruction PDF file, and VT Pro files
to customize touchpanel displays.

Refer to the block diagrams on the next page. The CN-WP12F provides button press
signals (source selector, ON/OFF, MUTE, transport and volume control) to the
CrestronHome Control module of the CrestronHome Programming Kit. This module
processes the signals according to the program and provides feedback signals that are
used to illuminate the LED indicators of the CN-WP12F. The button press signals of
the CN-WP12N (CLEAR, ENTER, and numeric digits 0 through 9) are input to the
CrestronHome Room Keypad module. This module processes the button press
signals and provides feedback for the LED of the ENTER button.

NOTE: In the following example, the input signals of the CrestronHome Room
Keypad module have been rearranged for clarity. When programming, refer to the
signal names and proper inputs of the SIMPL Windows symbol.

How to Create the Program

Configuration Manager

Use the Configuration Manager workspace (Project | Configure System) in SIMPL
Windows to select and configure all the devices that need to be included into the
system. For this example, from the Control Systems folder in the Device Library
select CNMSX-PRO. Drag and drop the CN-WP12F (Wired Panels folder in the
Device Library) into System View. For this example, the NET ID of the CN-WP12F
is being set to 4C as shown on the next page. Drag and drop the CN-WP12N (Wired
Panels folder in the Device Library) also into System View and set the NET ID to 48.

NOTE: SIMPL Windows v1.30.01 or later is required to program the control
system containing the CN-WP12F and CN-WP12N. If using an earlier version of
SIMPL Windows, Crestron recommends a SIMPL Windows and operating system
upgrade. The latest version can be obtained from the Downloads page of Crestron’s
website (www.crestron.com). New users are required to register in order to obtain
access to the FTP site.
