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
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, 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.

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 24 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 24.

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 CEN-RFGW-EX;
refer to the Crestron Toolbox help file for details.
• Enter the IP address, IP mask, and default router of the
CEN-RFGW-EX via the Crestron Toolbox (Functions | Ethernet
Addressing); otherwise, leave DHCP enabled. (The unit ships with
DHCP enabled.)
• Confirm Ethernet connections between CEN-RFGW-EX and PC.
If connecting through a hub or router, use CAT5 straight through
cables with 8-pin RJ-45 connectors. Alternatively, use a CAT5
crossover cable to connect the two LAN ports directly without
using a hub or router.
• Use the Address Book in Crestron Toolbox to create an entry for
the CEN-RFGW-EX with the CEN-RFGW-EX’s TCP/IP
communication parameters.
• Display the “System Info” window (click the icon) and select
the CEN-RFGW-EX entry.

• Gateway channel 15 is adjacent to Wi-Fi channels 1 and 6.
• Gateway channels 16-19 are within Wi-Fi channel 6 band.
• Gateway channel 20 is adjacent to Wi-Fi channels 6 and 11.
• Gateway channels 21-24 are within Wi-Fi channel 11 band.
• Gateway channel 25 is adjacent to Wi-Fi channel 11.
• Gateway channel 26 is neither within or adjacent to any Wi-Fi
band.
For detailed information on RF channels, refer to “Appendix A: The RF
Spectrum” on page 24.
After establishing communication with the CEN-RFGW-EX (refer to
“Establishing Communication” which starts on page 15), use Crestron
Toolbox to set the operating channel.
RF Channel Each gateway can communicate with up to 16 infiNET EX devices on the
same channel. Each device must have an RF channel assignment that
matches the RF channel assignment of the gateway.
There are 16 possible channels ranging from 11 to 26.

Appendix A: The RF Spectrum
Crestron’s RF network provides 16 RF channels in the 2.4GHz ISM*
band, specifically IEEE 802.15.4 channels 11 through 26. The 16
channels define the frequencies at which the RF device will
communicate.
RF devices on different channels will not communicate or interfere with
each other. However, since some of the channels are in the 2.4GHz ISM
band (as shown in the following diagram), interference can occur with
other devices using this band, such as 802.11b/g Wi-Fi devices, Crestron
infiNET™ devices or Zigbee devices, although the differing protocols
will not allow a link to be established or data to be transferred. Wireless
2.4GHz telephones and microwave ovens may also cause interference
with the network.
* Industrial, Scientific and Medical; refers to frequency range used for unlicensed
communications applications, such as Wi-Fi.

Appendix B: Optimum RF Reception Guidelines
Many factors can affect the reliability of RF communication between an
RF gateway and an RF device. While an effort has been made to
determine operating specifications, some specifications are not constant.
RF Communication can be limited by several factors including but not
limited to EMI (electromagnetic interference), intervening objects,
antenna orientation and receiver placement. To obtain maximum
reliability and performance, some basic rules for installing RF
transceivers are listed below.
Minimize Interference
RF reception range can be hindered by spurious EMI noise that may
interfere with or mask the desired frequency, thereby reducing useable
range. EMI is generated by any electrical device at various RF noise
levels depending on the device. Sources of EMI include computers, video
equipment, digital processors, lighting dimmers, lighting ballasts, motors
or any large AC source. Every effort should be made to separate any RF
transceiver from these sources of RF noise including Audio Visual
equipment in racks. If a gateway must be installed in an equipment rack,
make sure you have ample separation between the equipment and the
gateway.
Gateway Placement
Optimum reception for any RF transceiver is obtained by installing the
gateway transceiver in an open area or shelf with a clear line of sight (no
obstructions between gateway and receiver). Crestron recommends that
the gateway is at least five to six feet high for best results. Avoid placing
transceivers or transmitters at a low height or on the ground. Placing RF
equipment near metal objects, walls, corners or metal enclosures will
compromise RF propagation and reception. Try to avoid installing
gateways in equipment racks, service rooms, electrical closets or in
rooms other than that which the panel is located.

Antenna Orientation
The antenna orientation on Crestron gateways has considerable effect on
range and reliability. The best orientation is unique to each installation.
There are three possible antenna orientations:
Point the antenna horizontally (parallel to the ground)
Point the antenna vertically.
Point the antenna at a right angle to the gateway.
Never point the antenna downward as this will decrease range and
reliability. Refer to illustration below and those on the following page for
examples of the different antenna orientations.
NOTE: RF propagation is best from the sides of the antenna.
