Crestron CEN-RFGW-EX infiNET EX™ Gateway
infiNET EX™ Gateway:
CEN-RFGW-EX
Introduction
The CEN-RFGW-EX gateway is an RF wireless transceiver designed for
use with the MLX-2 infiNET EX™ LCD Handheld Remote and other
Crestron®infiNET EX devices as part of a Crestron control system.
“Wi-Fi friendly” RF technology permits selection from 16 ISM*channels
within the 2.4 GHz spectrum to minimize the possibility of interference
with other RF equipment including 802.11 devices. The CEN-RFGW-EX
affords a range of approximately 100 feet (30 meters) indoors.
Up to 16 MLX-2 remotes or other infiNET EX devices, may be
associated with a single CEN-RFGW-EX. Setup is simple, utilizing
dynamic discovery to locate and acquire each remote automatically. Each
wireless connection is monitored continuously, diligently keeping track
when remotes go to sleep or wander out of range and restoring
communications seamlessly when any remote reappears on the network.
More than just a wireless bridge, the CEN-RFGW-EX actually functions
as a proxy for each MLX-2, processing every button press and display
change right onboard. So when a remote goes to sleep or out of range, the
gateway continues communicating with the control system, keeping sync
with every command and updating the remote’s display the instant it
awakens or reconnects.
* Industrial, Scientific and Medical; refers to frequency range used for unlicensed
communications applications, such as Wi-Fi.

InfiNET EX™ Gateway Crestron CEN-RFGW-EX
A choice of Cresnet®or PoE (Power-over-Ethernet) powers the
CEN-RFGW-EX right through the network wiring, eliminating the need
for a separate wall-wart power supply. The CEN-RFGW-EX is available
with a PoE Injector, PWE-4803RU included (as model
CEN-RFGW-EX-PWE), which simply connects inline with the Ethernet
cable connected to the gateway, allowing for installation at any
convenient location. Or, using Crestron’s 5-port PoE switch
(CEN-SW-POE-5, sold separately), up to four gateways and other PoE
devices can be powered from a single location, simplifying design and
wiring.

Setup
Network Wiring
When wiring the Cresnet and Ethernet 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 (www.crestron.com/calculators).
Cresnet For networks with 20 or more devices, use a Cresnet Hub/Repeater
(CNXHUB) to maintain signal quality.
For more details, refer to “Check Network Wiring” which starts on page
27.
Ethernet The CEN-RFGW-EX can also use high-speed Ethernet for
communications between the device and a control system, computer,
digital media server and other IP-based devices.
For information on connecting Ethernet devices in a Crestron system,
refer to the latest version of the Crestron e-ControlReference Guide
(Doc. 6052), which is available for download from the Crestron website
(www.crestron.com/manuals).

Identity Code
Net ID The Net ID of the CEN-RFGW-EX has been factory set to 2F. The Net
IDs of multiple CEN-RFGW-EX devices in the same system must be
unique. Net IDs are changed from a personal computer (PC) via Crestron
Toolbox™ (refer to “Establishing Communication” which starts on page
20).
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.
IP ID The IP ID is set within the CEN-RFGW-EX’s table using Crestron
Toolbox. For information on setting an IP table, refer to the Crestron
Toolbox help file. The IP IDs of multiple CEN-RFGW-EX devices in the
same system must be unique.
When setting the IP ID, consider the following:
• The IP ID of each unit must match an IP ID specified in the
SIMPL™ Windows®program.
• Each device using IP to communicate with a control system must
have a unique IP ID.

Installation
Ventilation To prevent overheating, do not operate this product in an area that
exceeds the environmental temperature range listed in the table of
specifications. Consider using forced air ventilation and/or incrementing
the spacing between units to reduce overheating. Consideration must be
given if installed in a closed or multi-unit rack assembly since the
operating ambient temperature of the environment may be greater than
the room ambient temperature. Contact with thermal insulating materials
should be avoided on all sides of the unit.
Placement
Tips When installing a CEN-RFGW-EX near another CEN-RFGW-EX, for
optimum performance, keep the following in mind:
• Do not place multiple gateways on the same channel. Refer to
“Appendix A: The RF Spectrum” on page 30 for details.
• Gateways on adjacent channels should be at least 12 feet
(3.7 meters) apart.
• Gateways on non-adjacent channels should be at least three feet
(0.9 meters) apart.
When installing a CEN-RFGW-EX near a Wi-Fi access point, for
optimum performance, keep the following in mind:
• Gateways on RF channels adjacent to operating Wi-Fi channels
should be placed at least 12 feet (3.7 meters) from the nearest
Wi-Fi access point.
• Gateways on RF channels that are non-adjacent to Wi-Fi channels
should be located at least six feet (1.8 meters) from the nearest Wi-
Fi access point.
For more information on RF channels and their interaction with the
Wi-Fi spectrum, refer to “Appendix A: The RF Spectrum” on page 30.
For additional information on optimal gateway placement, refer to
“Appendix B: Optimum RF Reception Guidelines” which starts on page
31.

Hardware Hookup
Make the necessary connections as called out in the illustrations that
follow this paragraph. Refer to “Network Wiring” on page 11 before
attaching the 4-position terminal block connector. Apply power after all
connections have been made.
NOTE: Power should be supplied through either the LAN PoE port or
the NET port but not both.
When making connections to the CEN-RFGW-EX, use Crestron power
supplies for Crestron equipment.

Earliest Version Software Requirements for the
PC
NOTE: Crestron recommends that you use the latest software to take
advantage of the most recently released features. The latest software is
available from the Crestron website.
Crestron has developed an assortment of Windows-based software tools
to develop an infiNET system. For the minimum recommended software
versions, visit the Version Tracker page of the Crestron website
(www.crestron.com/versiontracker).
Programming with Crestron SystemBuilder
Crestron SystemBuilder is the easiest method of programming but does
not offer as much flexibility as SIMPL Windows. For additional details,
download SystemBuilder from the Crestron website and examine the
extensive help file.
Programming with SIMPL Windows
NOTE: While SIMPL Windows can be used to program the
CEN-RFGW-EX, it is recommended to use SystemBuilder for
configuring a system.
SIMPL Windows is Crestron’s premier software for programming
Crestron control systems. It is organized into two separate but equally
important “Managers”.
