Crestron C2N-TXM XM Satellite Radio Tuner
Operations Guide - DOC. 6234A XM Satellite Radio Tuner: C2N-TXM •7
Industry Compliance
As of the date of manufacture, the C2N-TXM 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/calculators).
NOTE: When installing network wiring, refer to the latest revision of the wiring
diagram(s) appropriate for your specific system configuration, available from the
Crestron website.
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
R = Resistance (refer to the following table).
L = Length of run (or chain) in feet.
P = Cresnet power usage of entire run (or chain).
R < L x P
40,000 Where:

XM Satellite Radio Tuner Crestron C2N-TXM
8 •XM Satellite Radio Tuner: C2N-TXM Operations Guide - DOC. 6234A
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 22 for details of
the SIMPL Windows procedure.
Refer to the note on page 28 for
a definition of Viewport.
The Net ID of the C2N-TXM has been factory set to 55. The Net IDs of multiple
C2N-TXMs 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 29. 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-TXM Net IDs:
Method A (Cresnet address-settable ID), described on the next page, applies to
C2N-TXMs 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-TXMs 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

Crestron C2N-TXM XM Satellite Radio Tuner
Operations Guide - DOC. 6234A XM Satellite Radio Tuner: C2N-TXM •9
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-TXM Net ID.
Method A (Cresnet address-settable ID)
1. Ensure that the C2N-TXM 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-TXM from the
Current Network Devices text window.
5. Select the new Net ID for the C2N-TXM 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 C2N-TXM 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-TXMs 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
figure on the next page.)

10 •XM Satellite Radio Tuner: C2N-TXM Operations Guide - DOC. 6234A
“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:
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 figure on the next page.)

Antenna Installation
It is important to position the supplied high-gain antenna to receive the strongest
possible signal either from the satellite (preferred) or from a terrestrial repeater
station. This can be done before installing the XM Tuner in your Cresnet system.
Crestron recommends placing the antenna either outside or near a window with a
southern exposure. The antenna should face south if you are in the eastern half of the
continental US, or south/southeast if you are in the western half of the country.
The antenna can be mounted on a horizontal or vertical surface, using screws or
double-faced tape. The following figure shows the antenna mounting plate with
dimensions for mounting screw locations.
Connect the cable of the supplied Remote Sensitivity Indicator to the SIG A and B
connectors on the back of the XM Tuner. Place the indicator near the antenna and
rotate and/or tilt the antenna to obtain the strongest possible signal, as described in
the following table, and secure the antenna in position.
