Introduction
The CEN-RFGW-EX gateway is an RF wireless transceiver designed for
use with Crestron® infiNET EX™ devices as part of a Crestron control
system. “Wi-Fi friendly” RF technology permits selection from 16 ISM1
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 150 feet (46 meters)
indoors2.
Up to 100 infiNET EX devices3, may be associated with a single
CEN-RFGW-EX. Setup is simple, utilizing dynamic discovery to locate
and acquire each device automatically. Each wireless connection is
monitored continuously, diligently keeping track when devices go to
sleep or wander out of range and restoring communications seamlessly
when any device reappears on the network.
1. Industrial, Scientific and Medical; refers to frequency range used for unlicensed
communication applications, such as Wi-Fi.
2. Specified range is for direct device to gateway communication. Effective network
range is larger due to the mesh networking capabilities of infiNET EX. Refer to
individual infiNET EX device documentation for details on device to device
ranges.
3. The Crestron MLX-2 infiNET EX LDC Handheld Remote will only work with
this product if the gateway has no other devices acquired to it. The gateway must

After establishing communication with the CEN-RFGW-EX (refer to
“Establishing Communication” which starts on page 18), use Crestron
Toolbox to set the operating channel.
RF Channel Each gateway can communicate with up to 100 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.
Setting RF channel is done from a PC via Crestron Toolbox. To access
this in Toolbox, select Functions | infiNET EX Gateway…. Refer to the
Toolbox Help file and search for “infiNET EX Gateway” for more

Acquiring the
infNET EX
device
Crestron infiNET EX devices can communicate with a CEN-RFGW-EX
only if they have been acquired by that CEN-RFGW-EX. The Acquire
mode can be activated from Crestron Toolbox (recommended) or with
the ACQUIRE button on the CEN-RFGW-EX.
NOTE: To access this in Toolbox, select Functions | infiNET EX
Gateway…. Refer to the Toolbox Help file and search for “infiNET EX
Gateway” for more details.
NOTE: Use Toolbox to set the RF channel before starting the acquire
process. The default RF channel is 15. If you change the RF channel on a
device, it will need to be acquired again.
NOTE: The Acquire mode can be activated approximately 15 seconds
after applying power to the CEN-RFGW-EX.
NOTE: In an environment with multiple gateways, only one gateway
should be in the Acquire mode at a time.
NOTE: The CEN-RFGW-EX must be placed in Acquire mode before an
infiNET EX device is placed in the Acquire mode.
To acquire an infiNET EX device via the ACQUIRE button on the
CEN-RFGW-EX:
1. Press ACQUIRE on the CEN-RFGW-EX to enter the Acquire
mode. The accompanying LED will illuminate, indicating the unit
is ready to link to infiNET EX devices.
NOTE: The Acquire mode will automatically deactivate after one
hour. This default timeout period can be changed from Toolbox.
2. Bring the infiNET EX device within range of the gateway and
place it in the Acquire mode as described in its manual. The device
will be automatically acquired by the gateway within two minutes
after it enters Acquire mode.
3. Repeat step 2 for each infiNET EX device to be acquired.
4. Press ACQUIRE on the CEN-RFGW-EX to exit the Acquire
mode. The LED will turn off.

Crestron CEN-RFGW-EX infiNET EX™ Gateway
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
used in the following equation to calculate the cable length value on the
equation’s left side.
Cable Length Equation
L = Length of run (or chain) in feet
R = 6 Ohms (Crestron Certified Wire: 18 AWG (0.75 mm ))
or 1.6 Ohms (Cresnet HP: 12 AWG (4 mm ))
P = Cresnet power usage of entire run (or chain)
2
2
L < 40,000
R x P
Where:
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 (101 meters). If Cresnet HP is used for the
same run, its length could extend to 1250 feet (381 meters).
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.
Strip and Tin
Wire
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 Use of a Cresnet Hub/Repeater (CNXHUB) is advised whenever the
number of Cresnet devices on a network exceeds 20 or when the
combined total length of Cresnet cable exceeds 3000 feet (914 meters).

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.

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.
