Extended Range Wireless Gateway Crestron CEN-ERFGW-POE
Extended Range 2.4 GHz RF Technology
Crestron Extended Range (ER) wireless technology (formerly called
“High Powered RF”) affords robust bidirectional wireless
communications over an impressive distance of approximately 100 to
200 feet (~30 to 61 meters) indoors and up to 1000 feet (~305 meters)
outdoors. Roaming capability allows for even greater coverage using up
to eight CEN-ERFGW-POE gateways. “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-ERFGW-POE continuously monitors each device on the
network, diligently keeping track when any device goes to sleep, shuts
down or wanders out of range, restoring communications seamlessly
when the device reappears on the network. The control data to and from
each associated device is passed cleanly and quickly through the gateway
without any cumbersome processing to affect performance. Excessive
network traffic and noise are combated using intelligent data routing to
ensure every control signal is delivered intact to its intended destination
without interruption.
Easy Setup
Setting up a network of ER wireless devices is simple, utilizing dynamic
discovery to locate and acquire each RF device automatically. Up to 16
ER wireless touch screens and remotes can be linked to a control system
via a single CEN-ERFGW-POE gateway. Additional gateways must be
installed to support more devices, with up to 16 gateways possible in a
complete system (RF conditions allowing).
Single Wire Hookup
Wired communications between the CEN-ERFGW-POE gateway and the
control system can be via Cresnet or Ethernet, with power for the
gateway delivered over the same Cresnet or Ethernet connection. Power
over Ethernet (PoE) simply requires the presence of an 802.3af PoE
power source. Crestron offers the PWE-4803RU PoE Injector, which
connects in-line with the Ethernet cable, allowing for installation at any
* Industrial, Scientific and Medical, refers to frequency range used for unlicensed
communication applications, such as Wi-Fi.

convenient location between the gateway and the network switch. The
PWE-4803RU is capable of powering a single gateway and is available
separately or packaged with the gateway as model
CEN-ERFGW-POE-PWE.
Crestron also offers Ethernet switches with built-in PoE (models
CEN-SW-POE-5 and CEN-SWPOE-24, both sold separately), affording
a complete high performance networking solution capable of providing
PoE for multiple gateways and other PoE devices. Using an Ethernet
switch with built-in PoE eliminates the need for separate PoE injectors.

Check Network Wiring
Use the
Right Wire
Calculate
Power
In order to ensure optimum performance over the full range of the
installation topology, use Crestron Certified Wire only. Failure to do so
may incur additional charges if support is required to identify
performance deficiencies because of using improper wire.
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 (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 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 <
Where:
40,000
R x P
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).
28 • Wireless Gateway: CEN-ERFGW-POE Operations & Installation Guide – DOC. 7158A
Crestron CEN-ERFGW-POE Extended Range Wireless Gateway
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
Add Hubs
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.
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 2.4 GHz ISM*
band, specifically IEEE 802.15.4 channels 11 through 26. The 16
channels define the frequencies at which the RF device communicates.
RF devices on different channels do not communicate or interfere with
each other. However, since some of the channels are in the 2.4 GHz 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 do
not allow a link to be established or data to be transferred. Wireless 2.4
GHz 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 there is 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
compromises RF propagation and reception. Try to avoid installing
gateways in equipment racks, service rooms, electrical closets or in
rooms other than that which the touch screen is located.

Crestron CEN-ERFGW-POE Extended Range Wireless Gateway
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 decreases 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.
