When wiring the network, consider the following:
• Use Crestron Certified Wire.
• Use Crestron power supplies for Crestron equipment.
• Provide sufficient power to the system.
CAUTION: 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
).
• For larger networks, use a Cresnet Hub/Repeater (CNXHUB) to
maintain signal quality.
For more details, refer to “Check Network Wiring” on page 21.
Identity Code
The Net ID of the C2N-IRGW-F has been factory set to 2D. The Net IDs
of multiple C2N-IRGW-F devices in the same system must be unique.
Net IDs are changed from a personal computer (PC) via the Crestron
Toolbox™ (refer to “Establishing Communication” on page 18).
When setting the Net ID, consider the following:
• The Net ID of each unit must match an ID code specified in the
SIMPL Windows program.
• Each network device must have a unique Net ID.
For more details, refer to the Crestron Toolbox help file.

Universal Remotes
Any universal remote transmitting RC5 code (and some Sharp codes) can
communicate with the Crestron control system and allow the user to
select and activate any function in the control system. An RC5 code is 14
bits long. Each code includes a 5-bit address (or system) and a 6-bit
command. Sharp uses a different IR protocol, but some of their codes are
acceptable.
NOTE: The Philips Pronto contains built-in RC5 commands for out-ofthe-box use.

p
Setting up a
Philips Pronto
is easy!
Universal
remotes require
two multi-step
rocedures for
setup.
If using the Philips Pronto, select RC5 code communication. For the
Philips Pronto, the RC5 system number is equivalent to Crestron's
Transmitter ID code, which is a unique identifier assigned to each
transmitter. Likewise, RC5 command number is equivalent to Crestron's
Button ID, which is synonymous with the join number used in SIMPL
Windows. There is no need to perform the two multi-step procedures in
the subsequent sections.
NOTE: Typically, codes used by Magnavox, Marantz and Philips
audio/video equipment utilize RC5 codes for transmission. Some codes
used by Sharp Electronics Corporation are also usable.
Some devices from Magnavox, Marantz and Philips are designed to
understand certain kinds of infrared signals sent by remote controls,
specifically, signals belonging to the RC5 code set. Two procedures are
required to setup a universal remote. The first procedure verifies that the
universal remote chosen does transmit an identifiable code and therefore
can communicate with the Crestron control system. The second
procedure maps the buttons on the universal remote so that they can be
used in the SIMPL Windows program.
Code Verification
Each universal remote comes with its own manual, which lists codes by
device and manufacturer. The purpose of this procedure is to select and
program a code into the universal remote so that it can communicate with
the Crestron control system. All that is required to complete this
procedure is the C2N-IRGW-F, a PC running the Crestron Toolbox, a
Crestron control system connected to the PC and any universal remote
(complete with batteries and manufacturer's manual). The control system
should be running a valid SIMPL Windows program that includes the
C2N-IRGW-F at the proper Net ID so that it can be polled.
1. Using Cresnet cable, connect the pigtail wires from the
C2N-IRGW-F to the Crestron control system (NET port). Refer to
“Network Wiring” on page 6 for details.
2. Open the Crestron Toolbox.
3. Display the “System Info” window (click the

Transmitter” window, as shown after this step.
icon).

“Identify Transmitter” Window
5. Point the universal remote at the C2N-IRGW-F and program the
remote with an RC5 code (some Sharp codes are acceptable as
well) as outlined in the manufacturer's manual.
NOTE: Crestron recommends that codes from manufacturers other than
the manufacturer of the device being controlled be used to avoid IR
transmission conflict. For example, if the controlled device is a Sony
DVD player, an acceptable code from any manufacturer (except Sony)
should be used to communicate with the Sony DVD player via the
Crestron control system.
6. Press one or more function buttons on the remote and observe the
“Identify Transmitter” window on the PC.
a) If there is no activity while pressing buttons on the remote, the
code chosen was not an acceptable code or the code could not
be decoded. Repeat steps 5 and 6 with another code.
b) If activity is observed with each button press, the code used was
an acceptable code and the Crestron control system can accept
commands from the universal remote.
Map the Universal Remote
Once communication between the Crestron control system and the
universal remote is achieved, it is necessary to understand what
Operations & Installation Guide – DOC. 6574A IR Gateway: C2N-IRGW-F • 11
IR Gateway Crestron C2N-IRGW-F
commands are transmitted and to which devices. Transmitter ID codes
are revealed in the “Identify Transmitter” window.
Each universal remote has a number of source selection buttons on it
(i.e., TV, VCR, DVD, AUX). Typically, those buttons are used when
setting up the remote with an acceptable code (refer to “Code
Verification” on page 10). If an acceptable code is transmitted during that
procedure, Crestron assigns the code with an identifier in the “Identify
Transmitter” window. For example, in the window shown below, the
Transmitter ID (Hex): field shows the number 13. Since the identifier
falls in the range of 00 to 1F, the device communicates using an
acceptable RC5 code.
Positive Transmitter Identification
The next logical question is, “What is the Button ID?” The purpose of
this next procedure is to map the buttons on the universal remote so that a
list can be generated and used for reference when creating the SIMPL
Windows program. A decimal identification number (or Button ID
(Decimal) as shown in the “Identify Transmitter” window) corresponds
to each physical press on the universal remote. This procedure picks up
where the code verification procedure left off.
1. Complete steps 1 through 6 in “Code Verification” on page 10.
2. Wherever convenient (i.e., Notepad on the PC or a piece of scrap
paper) create a table for recording the Button ID (Decimal) number
associated with each button press on the universal remote.
12 • IR Gateway: C2N-IRGW-F Operations & Installation Guide – DOC. 6574A
Crestron C2N-IRGW-F IR Gateway
“Appendix: Mapping Table” on page 24 contains a table to record
this information. Create as many copies of the table as necessary.
3. Click the Clear button in the “Identify Transmitter” window to
reset the setup.
4. Press a single button on the universal remote and observe the
“Identify Transmitter” window.
5. Record the button title and ID for the action in step 4.
6. Repeat steps 4 and 5 for each button that is to be mapped. Refer to
the sample after this step.
Sample of Completed Mapping Table
7. Repeat this entire procedure (steps 2 through 6) for each source
selection button on the universal remote that requires
programming.

Uploading and Upgrading
Crestron recommends using the latest programming software and that
each device contains the latest firmware to take advantage of the most
recently released features. However, before attempting to upload or
upgrade it is necessary to establish communication. Once communication
has been established, files (for example, programs or firmware) can be
transferred to the control system (and/or device). Finally, program checks
can be performed (such as changing the device ID or creating an IP table)
to ensure proper functioning.
Establishing Communication
Use Crestron Toolbox for communicating with the C2N-IRGW-F; refer
to the Crestron Toolbox help file for details. There is a single method of

Check Network Wiring
In order to ensure optimum performance over the full range of your
installation topology, Crestron Certified Wire and only Crestron Certified
Wire may be used. Failure to do so may incur additional charges if
support is required to identify performance deficiencies because of using
improper wire.
Calculate
Power
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).
When calculating the length of wire for a particular Cresnet run, the wire
gauge and the Cresnet power usage of each network unit to be connected
must be taken into consideration. Use Crestron Certified Wire only. If
Cresnet units are to be daisy-chained on the run, the Cresnet power usage
of each network unit to be daisy-chained must be added together to
determine the Cresnet power usage of the entire chain. If the unit is
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 wire gauge and the Cresnet power usage of the run should be

Make sure the cable length value is less than the value calculated on the
right side of the equation. For example, a Cresnet run using 18 AWG
Crestron Certified Wire and drawing 20 watts should not have a length of
run more than 333 feet. If Cresnet HP is used for the same run, its length
could extend to 1250 feet.
NOTE: All Crestron certified 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.
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.
Add Hubs
For larger networks (i.e., greater than 28 network devices), it may
become necessary to add a Cresnet Hub/Repeater (CNXHUB) to
maintain signal quality throughout the network. Also, for networks with
lengthy cable runs it may be necessary to add a Hub/Repeater after only
20 devices.
