FM Radio Tuner: C2N-TFM
Introduction
Features and Functions
The Crestron®C2N-TFM is a Crestron-controlled FM Radio tuner (FM Tuner)
designed to work stand-alone or with the companion AM/Weather band tuner, the
C2N-TAMWX (AM/WX Tuner). The FM Tuner adds high-quality FM radio
programming to your whole-house audio distribution system.
The FM Tuner is designed to work in a Crestron control system (Cresnet®system).
You can use any Crestron multi-mode touchpanel to search through the stations and
control tuner functions. The built-in RDS/RBDS feature permits display of digital
data, such as program type, clock time, traffic announcements, etc., that may be
transmitted along with regular FM programming. (Refer to “RDS/RBDS Feature” on
page 2.) User-programmable presets let you quickly select your favorite station.
Audio output from the FM Tuner can be routed to a local amplifier or to a surround
sound decoder such as the C2N-DAP8 or C2N-DAP8RC. Output can also be routed
to a CNX-BIPAD8 for distribution to other rooms via CAT5 cabling. (Refer also to
the configuration diagram on page 12.)
Functional Summary
• Headphone connector for local monitoring of audio output
• Up to twenty presets for fast program selection
• RDS/RBDS feature for display of program types, traffic
announcements, GMT-based clock time and more
• Two RCA connectors for line-level FM stereo output
• RJ-45 connector provides link (up to 500 feet) to
C2N-TAMWX AM/Weather band tuner
• Integrated configuration lets local FM Tuner buttons
control AM/WX Tuner

RDS/RBDS Feature
The Radio Data System (RDS), a European standard, and Radio Broadcast Data
System (RBDS), a North American standard, permit broadcasters to use a sub-carrier
frequency to transmit inaudible digital data along with their regular FM
programming to receivers equipped to process the data.
The FM Tuner circuitry is compatible with the RDS/RBDS standards; the example
program discussed later in this guide provides some typical applications of this
feature, such as the display of program type name, UTC (universal time clock) data,
program name and category, and traffic information. A typical benefit of this feature
is the ability to search for stations based on program type.
Refer to “Appendix: RDS/RBDS Function Support” on page 41 for more
information.
Mute and Mono Functions
The FM Tuner incorporates automatic as well as manual selection of mute and mono
mode functions.
• The tuner can be put into mono/stereo mode or mute mode via the
touchpanel.
• The tuner cannot be put into mono/stereo mode or mute mode via the tuner
controls.
• After tuning to a station, the tuner will automatically switch to mono mode
if the signal level is low and mono mode is off.
• The tuner automatically mutes the output during rapid scan functions.
• After tuning to a station, the radio will automatically mute if the signal level
is too low and the radio-forced mono mode is off.
• The auto mute/mute feature can be disabled via the touchpanel.

PWR (Power)
This green LED illuminates when power is supplied to the C2N-TFM.
NET
This yellow LED illuminates when communication between the control system and
the C2N-TFM is established (the unit is polled on the network). Illumination
indicates that the program currently loaded has a network device defined at the same
ID as the C2N-TFM. The LED flashes or remains on when communication with the
processor occurs.
BAND Switch
Use the BAND switch to select between the AM, FM and WX (weather) bands. The
corresponding red LEDs (AM, FM, WX) illuminate as each band is selected, and the
five-digit display shows the appropriate values. If the AM/WX Tuner is not included in
your configuration, the AM and WX modes cannot be selected.
MODE Switch, KJ (Up/Down) Buttons, and Display
Use the MODE switch to select between the signal, volume, preset, tune, and scan
modes. The corresponding red LEDs (SIG, VOL, PRE, TUNE, and SCAN)
illuminate as each mode is selected. In each mode, the five-digit display shows the
appropriate values.
In the signal mode, the display shows a letter (d = distance mode; L = local mode) and
the corresponding relative signal strength (01 through 99). The FM Tuner defaults to
distance mode; when the FM signal level is too high, the program automatically
switches to local mode and the signal is attenuated by 10 dB.
In the volume mode, the up/down buttons select ten volume levels (0 through 9) for the
signal (mono) supplied to the headphone jack.

Crestron C2N-TFM FM Radio Tuner

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, available from the
Downloads | Product Manuals | Wiring Diagrams section of the Crestron website
(www.crestron.com).
When calculating the wire gauge for a particular Cresnet run, the length of the run
and the power 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 power factor of
each unit to be daisy-chained must be added together to determine the power factor
of the entire chain. If the unit is a home-run from a Crestron system power supply
network port, the power factor of that unit is the power factor of the entire run. The
length of the run in feet and the power factor of the run should be used in the
resistance equation below to calculate the value on the right side of the equation.
Resistance Equation
R = Resistance (refer to table below).
L = Length of run (or chain) in feet.
PF = Power factor of entire run (or chain).
R < L x PF
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 following table.
Wire Gauge Values
RESISTANCE WIRE GAUGE
4 16
6 18
10 20
15 22
13 Doubled CAT5
8.7 Tripled CAT5
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.

Crestron C2N-TFM FM Radio Tuner
Operations Guide - DOC. 6233A FM Radio Tuner: C2N-TFM •9
Identity Code
Every equipment and user interface within the network requires a unique identity
code (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 18 for details of
the SIMPL Windows procedure.
Refer to the note on page 33 for
a definition of Viewport.
The Net ID of the C2N-TFM has been factory set to 56. The Net IDs of multiple
C2N-TFMs 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 34. If communication
cannot be established, refer to the “Troubleshooting Communications” section in the
respective Operations Guide for the control system.
There are two different methods—Method A or Method B—for setting the C2N-
TFM Net IDs:
Method A (Cresnet address-settable ID), described below, applies to C2N-TFMs in
a Cresnet system with a CNX control system or with a 2-Series control system
upgrade file (CUZ) version prior to 3.008, but can be used with later versions of
firmware and requires that a single unit be the only network device connected to the
control system.
Method B (Touch Settable IDs), which begins on the next page, applies to C2N-
TFMs in a Cresnet system with 2-Series control system upgrade file (CUZ) version
3.029 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. This method requires the use of the Crestron Viewport version
3.35 or later.
Use the appropriate method to set the C2N-TFM Net ID.
Method A (Cresnet address-settable ID)
1. Ensure that the C2N-TFM 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-TFM from the
Current Network Devices text window.
5. Select the new Net ID for the C2N-TFM 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.

FM Radio Tuner Crestron C2N-TFM
10 •FM Radio Tuner: C2N-TFM Operations Guide - DOC. 6233A
9. In the "Set Network ID" window, click Close.
NOTE: The new Net ID code may also be verified by selecting Diagnostic |
Report Network Devices in the Viewport (alternately, select F4).
10. Repeat this procedure for each C2N-TFM 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 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 C2N-TFMs 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. (Refer to the
following figure.)
“Set Net ID by TSID” Window
4. Click on the Search for Touch Settable Devices button. The system
searches the network and lists all TSID-enabled devices found. The list
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).

Crestron C2N-TFM FM Radio Tuner
Operations Guide - DOC. 6233A FM Radio Tuner: C2N-TFM •11
5. 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, and the list scrolls to and
highlights the device listing. The listing should show the device’s
current Cresnet ID.
6. Enter the Cresnet ID that the device should be set to and click OK. The
number you enter should appear on the list.
CAUTION: This function does not prevent you from setting duplicate IDs. Be sure
to check current assignments before entering the desired Cresnet ID number.
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 the TSID but not the serial
number, and your site installation list is based on device serial numbers. In this (or
the reverse) situation, do the following:
1. Open the Crestron Viewport.
2. From the Viewport menu, select Functions | Serial Number ÅÆ
TSID Conversion Tool. The “Serial Number ÅÆTSID Conversion
Tool” window is displayed. (Refer to the following figure.)
“Serial Number to TSID Conversion Tool” Window
3. Enter the serial number or TSID number as instructed; press the
appropriate button to obtain the corresponding number.
NOTE: Enter serial numbers, including spaces, exactly as they appear on the unit
label. Alpha characters in serial numbers or TSID numbers may be entered in upper
or lower case.

Setup is easy thanks to Crestron’s Windows-based programming software. The
Crestron SystemBuilder™creates a complete project, with no special programming
required. Crestron SystemBuilder completes all necessary programming for a base
system including all touchpanel screens and the control system program. Once
Crestron SystemBuilder creates the project, the system interfaces and program logic
can be customized. It can easily be modified with Crestron development tools (i.e.,
SIMPL Windows and Crestron VisionTools®Pro-e (VT Pro-e) software packages).
The program output of Crestron SystemBuilder is a SIMPL Windows program with
much of the functionality encapsulated in macros. Therefore, extending the
capabilities of the system is very easy. Crestron SystemBuilder and SIMPL
Windows are intended for users with different levels of programming knowledge.
Crestron SystemBuilder is easier to use for the beginning programmer, and much
faster for all programmers. However, it does not allow the degree of control and
flexibility that SIMPL Windows does. Of course, one can initiate programming
using the easiest method (Crestron SystemBuilder) and use advanced techniques that
are available from SIMPL Windows to customize the job.
Crestron SystemBuilder comes with templates for all supported interfaces. If a user
wishes to create a touchpanel project using templates with a different look-and-feel,
this can be accomplished by making a custom template. This custom template can
then be used by Crestron SystemBuilder to create the final project files to be loaded
into the panels. Alternatively, VT Pro-e can be used to tweak projects created with
the Crestron SystemBuilder or develop original touchpanel screen designs.

Programming with Crestron SystemBuilder
The easiest method of
p
rogramming, but does not
offer as much flexibility as
SIMPL Windows.
Crestron SystemBuilder offers automatic programming for such residential and
commercial applications as audio distribution, home theater, and video
conferencing. The interface of this tool guides you through a few basic steps for
designating rooms and specifying the control system, touchpanels, devices, and
functionality. Crestron SystemBuilder then programs the system, including all
touchpanel projects and control system logic.
Crestron SystemBuilder is fully integrated with Crestron's suite of software
development tools, including SIMPL Windows, VT Pro-e, and the Crestron
Database. Crestron SystemBuilder accesses these tools behind the scenes, enabling
you to easily create robust systems.
Programming with SIMPL Windows
NOTE: The following are acceptable file extensions for programs that include a
C2N-TFM, developed for specific control system types:
.smw projectname.smw (source file)
.spz projectname.spz (compiled file for 2-series)
.bin projectname.bin (compiled file for CNX generation)
.csz projectname.csz (compiled file for CNX generation with SIMPL+)
.ush projectname.ush (compiled file for CNX generation with SIMPL+
header file)
.usp projectname.usp (source code module for SIMPL+)
SIMPL Windows is Crestron's 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. SIMPL Windows offers drag and drop
functionality in a familiar Windows®environment.
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: In the following description, the PRO2 control system is used.
