The TV/FM Tuner is Touch Settable ID (TSID) ready. The SETUP pushbutton and
its associated LED are located on the rear panel and 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 TV/FM Tuner has 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) these devices may not cause harmful interference,
and (2) these devices must accept any interference received, including interference
that may cause undesired operation.
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 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

Crestron C2N-TTVFM TV & FM Radio Tuner
Operations Guide - DOC. 6266A TV & FM Radio Tuner: C2N-TTVFM •9
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.
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 15 for details of
the SIMPL Windows procedure.
Refer to the note on page 32 for
a definition of Viewport.
The Net ID of the TV/FM Tuner has been factory set to 47. The Net IDs of multiple
TV/FM Tuners 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 32. If communication
cannot be established, refer to the “Troubleshooting Communications” section in the
respective Operations Guide for the control system.

TV & FM Radio Tuner Crestron C2N-TTVFM
10 •TV & FM Radio Tuner: C2N-TTVFM Operations Guide - DOC. 6266A
There are two different methods—Method A or Method B—for setting the
C2N-TTVFM Net IDs:
Method A (Cresnet address-settable ID), described below, applies to C2N-TTVFMs
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 this page, applies to
C2N-TTVFMs 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-TTVFM Net ID.
Method A (Cresnet address-settable ID)
1. Ensure that the C2N-TTVFM 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 TV/FM Tuner from the
Current Network Devices text window.
5. Select the new Net ID for the TV/FM Tuner 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 Diagnostic |
Report Network Devices in the Viewport (alternately, select F4).
10. Repeat this procedure for each TV/FM Tuner 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.

Crestron C2N-TTVFM TV & FM Radio Tuner
Operations Guide - DOC. 6266A TV & FM Radio Tuner: C2N-TTVFM •11
1. Ensure that all TV/FM Tuners are connected to the control system.
2. Open the Crestron Viewport version 3.35 or later.

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).
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.

TV & FM Radio Tuner Crestron C2N-TTVFM
12 •TV & FM Radio Tuner: C2N-TTVFM Operations Guide - DOC. 6266A

NOTE: SIMPL Windows automatically changes Net ID values of a device added to
a program if a duplicate device or one with the same default Net ID already exists in
the program. Always ensure that the hardware and software settings of the Net ID
match. For Net ID hardware setting details, refer to “Identity Code” on page 9.
C2N-TTVFM Symbol in Programming Manager
Programming Manager is where programmers “program” a Crestron control system
by assigning signals to symbols. Due to the extensive functionality of the unit, a
single C2N-TTVFM symbol in SIMPL Windows would be too complex. Instead, the
C2N-TTVFM functions are divided into three sub-slots: Slot 01 – FM Tuner
Controls; Slot 02 – TV Tuner Controls; and Slot 03 – AM Tuner Controls. In
Program Manager, expand the C2N-TTVFM to view the individual sub-slots; then
drag the desired symbols to Detail View. The C2N-TTVFM sub-slots and
corresponding symbols are described in the following paragraphs. Because the FM,
TV, and AM Tuner controls symbols are also complex, each is illustrated and

C2N-TTVFM FM Tuner Controls Digital Input and Output Signal Descriptions
SIGNAL TYPE
AND NAME DESCRIPTION
Input: <FM_MuteAll> Mute toggle.
Mutes all audio (AUDIO OUT and headphone), for as
long as the input is high. Un-mutes the audio when the
input goes low.
High/1 = Mute all audio; Low/0 = Un-mute audio
Output:
<FM_Mute-F>
Indicates the current mute state of the unit. The output
will be high for as long as audio remains muted.
FM audio will mute whenever:
1) the <FM_MuteAll> input is high; or
2) the radio or television signal strength is too weak
to produce a clear signal, and the <FM_Mono>
input is low.
High/1 = Audio muted; Low/0 = Audio not muted
