CEN-GWEXER
Wireless Gateway
Installation Guide
For optimum performance when installing multiple CEN-GWEXERs near each other:
• Do not place multiple gateways on the same channel.
•
Place gateways at least 15 feet (4.6 meters) apart.
For optimum performance when installing a CEN-GWEXER:
• Place gateways at least 15 feet (4.6 meters) from the nearest Wi-Fi®access point.
• Place gateways at least 6 feet (1.8 meters) from the nearest Bluetooth®device.
For more information, refer to the Best Practices for Installation and Setup of Crestron RF
Products Reference Guide (Doc. 6689) at www.crestron.com/manuals.
Make Connections
Make the necessary connections as called out in the illustrations that follow. Apply power
after all connections have been made.
NOTE: When making connections to the CEN-GWEXER, use Crestron power supplies
for Crestron equipment.
NOTE: The antenna must be attached directly to the antenna connector. It can be
extended with an optional ANT-EXT-10 Antenna Extender (sold separately).
Hardware Connections for the CEN-GWEXER
Description
The Crestron®CEN-GWEXER is a 2-way RF wireless transceiver designed for use with
products that use the inNET EX®wireless communications protocol. It is also compatible
with Extended Range (ER) wireless devices. A single CEN-GWEXER gateway enables an
entire wireless network of Crestron remotes, keypads, lighting dimmers, motorized
shades, thermostats, door locks, and other devices to communicate with a Crestron
control system.
Installation
NOTES: Observe the following points:
• This product must be installed and used in accordance with appropriate electrical
codes and regulations.
• This product must be installed by a qualied electrician.

Check for the latest CEN-GWEXER rmware at www.crestron.com/rmware. Load the
rmware onto the device using Crestron Toolbox™ software.
The CEN-GWEXER can be mounted to a DIN rail or any vertical, at surface. It can also be
placed on any at, level surface. Refer to the illustrations below for DIN rail or any vertical,
at surface mounting examples.
NOTE: Do not install this gateway within 15 feet (4.6 meters) of other inNET EX
gateways, Crestron ER gateways, or Wi-Fi access points.
NOTE: The CEN-GWEXER can also be rack mounted. For rack mount installation, refer
to the RMK-IFE-1U Installation Guide (Doc. 7627) at www.crestron.com/manuals.

Federal Communications Commission (FCC) Compliance Statement
This device complies with part 15 of the FCC Rules. Operation is subject to the following conditions:
(1) This device may not cause harmful interference and (2) this device must accept any interference
received, including interference that may cause undesired operation.
CAUTION: Changes or modications not expressly approved by the manufacturer responsible for
compliance could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no guarantee
that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.
Industry Canada (IC) Compliance Statement
This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to
the following two conditions: (1) this device may not cause interference and (2) this device must
accept any interference, including interference that may cause undesired operation of the device radio
interference to other users, the antenna type and its gain should be so chosen that the equivalent
isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.

Industrie Canada (IC) Déclaration de conformité
Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux appareils radio
exempts de licence. L’exploitation est autorisée aux deux conditions suivantes : (1) l’appareil ne doit
pasproduire de brouillage, et (2) l’utilisateur de l’appareil doit accepter tout brouillage radioélectrique
subi, même si le brouillage est susceptible d’en compromettre le fonctionnement.
Conformément à la réglementation d’Industrie Canada, le présent émetteur radio peut fonctionner
avec une antenne d’un type et d’un gain maximal (ou inférieur) approuvé pour l’émetteur par Industrie
Canada. Dans le but de réduire les risques de brouillage radioélectrique à l’intention des autres
utilisateurs, il faut choisir le type d’antenne et son gain de sorte que la puissance isotrope rayonnée
équivalente (p.i.r.e.) ne dépasse pas l’intensité nécessaire à l’établissement d’une communication
satisfaisante.
To satisfy RF exposure requirements, this device and its antenna must operate with a separation
distance of at least 20 centimeters from all persona and must not be colocated in conjunction with any
other antenna or transmitter.

Assign the RF Channel
The RF channel of the CEN-GWEXER must be set prior to operation. The CEN-GWEXER
can operate on channels 11 through 26. Crestron recommends using RF channel 15 or 20.
The default RF channel is 15.
For optimum performance when installing a CEN-GWEXER in a Wi-Fi environment, do not
set the RF channel within a Wi-Fi channel band. Refer to the information below when
choosing the RF channel in a Wi-Fi environment.
• Gateway channels 11 through 14 are within the Wi-Fi channel 1 band.
• Gateway channel 15 is adjacent to Wi-Fi channels 1 and 6.
• Gateway channels 16 through 19 are within the Wi-Fi channel 6 band.
• Gateway channel 20 is adjacent to Wi-Fi channels 6 and 11.
• Gateway channels 21 through 24 are within the Wi-Fi channel 11 band.
• Gateway channel 25 is adjacent to Wi-Fi channel 11.
• Gateway channel 26 is neither within nor adjacent to any Wi-Fi band.
NOTE: Crestron’s RF devices can be divided into two categories: inNET EX devices
and Crestron Extended Range (ER) devices. inNET EX devices automatically set their
RF channel assignment to match the gateway’s channel, whereas ER devices must have
their RF channel manually assigned to match the gateway’s channel.
Use Crestron Toolbox to set the CEN-GWEXER’s RF channel. From the “System Info”
window, select Functions > inNET EX Gateway from the menu bar. Refer to the
Crestron Toolbox Help le for details.
Acquire Devices to the Gateway
Crestron inNET EX and ER devices can communicate with a CEN-GWEXER after it has
been acquired by a CEN-GWEXER. A device can be acquired to only one gateway.
Acquire mode can be activated using Crestron Toolbox or the ACQUIRE button on the
front panel.
NOTE: Use Crestron Toolbox to set the RF channel before starting the acquire
process. The default RF channel is 15. (ER devices must be congured to match the
channel setting on the gateway.)
NOTE: Acquire mode can be activated approximately 15 seconds after power is
applied to the CEN-GWEXER.
NOTE: In an environment with multiple gateways, only one gateway should be in
Acquire mode at a time.
NOTE: The CEN-GWEXER must be placed in Acquire mode before an inNET EX
device is placed in Acquire mode.
To acquire an inNET EX or ER device via the
ACQUIRE button on the CEN-GWEXER,
perform the following procedure:
1. Press ACQUIRE on the CEN-GWEXER to enter Acquire mode. The acquire LED
lights to indicate that the unit is ready to acquire inNET EX and ER devices.
NOTE: Acquire mode automatically deactivates after 1 hour. The timeout period
can be changed from Crestron Toolbox.
2. Bring the inNET EX or ER device within range of the gateway, and place it in
Acquire mode as described in its manual. Once it enters Acquire mode, the device
will be acquired within 2 minutes.
3. Repeat step 2 for each inNET EX or ER device that needs to be acquired.
4. Press ACQUIRE on the CEN-GWEXER to exit Acquire mode. The acquire LED
turns off.
