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-of-the-box use.
Setting up a Philips Pronto is easy! 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.

Crestron C2N-IRGW-1G IR Gateway/Receiver
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.
Universal remotes require two
multi-step procedures for setup. 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-1G, 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-1G at the proper Net ID so that it can be polled.
1. Using Cresnet cable, attach the C2N-IRGW-1G to the Crestron control
system (NET port). Refer to “Network Wiring” on page 5 for details.
2. Open the Crestron Toolbox.
3. Display the “System Info” window (click the icon).
4. From the Toolbox menu, select Functions | Identify Transmitter. The
software checks the baud rate and then opens the “Identify Transmitter”
window, as shown after this step.
“Identify Transmitter” Window
5. Point the universal remote at the C2N-IRGW-1G and program the
remote with an RC5 code (some Sharp codes are acceptable as well) as
outlined in the manufacturer's manual.
Operations & Installation Guide – DOC. 6468 IR Gateway/Receiver: C2N-IRGW-1G •9

IR Gateway/Receiver Crestron C2N-IRGW-1G
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 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 9). 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 on the next page,
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
10 •IR Gateway/Receiver: C2N-IRGW-1G Operations & Installation Guide – DOC. 6468

Crestron C2N-IRGW-1G IR Gateway/Receiver
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 9.
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. “Appendix:
Mapping Table” on page 19 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.
