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 Place gateways at least 12 feet (3.7 meters) from the nearest Wi-Fi access point. Place gateways at least 6 feet (1.8 meters) from the nearest Bluetooth device. 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 For Included Antenna USB to PC Power Supply Input LAN PoE Input If using a CEN-RFGW-EX-PWE, perform the following. 1. Attach the supplied ac power cord to the IEC 320 connector on the PoE (Power over Ethernet) injector. 2. Use a CAT5 cable to connect the LAN port of the PoE injector to the LAN. 3. Use a CAT5 cable to connect the LAN POE port of the PoE injector to the LAN PoE port of the CEN-GWEXER. 4. Insert the other end of the power cord into an active ac outlet. NOTE: In the listing of LAN PoE and LAN pins in the following image, arrows denote internal pin connections. LAN PoE and LAN Pin Assignments LAN PoE Pins 1. Data Pair 1 2. Data Pair 1 3.

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.

This product must be installed and used in accordance with appropriate electrical codes and regulations. This product must be installed by a qualied electrician. NOTE: Before using the CEN-GWEXER, ensure the device is using the latest rmware. Check for the latest CEN-GWEXER rmware at www.crestron.com/rmware. Firmware is loaded 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 (3 meters) of other inNET 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. DIN Rail Mounting Vertical Flat Surface Mounting NOTE: Do not use the supplied screws to mount the bracket to the bottom of the CEN-GWEXER if the device will be mounted on a DIN rail. Removing the CEN-GWEXER from the DIN rail will not be possible. 2. Bring the inNET 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 inNET 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. 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: Crestrons RF devices can be divided into two categories: inNET EX devices and Crestron Extended Range (ER) devices. inNET EX devices automatically set their RF channel assignment to match the gateways channel, whereas ER devices must have their RF channel manually assigned to match the gateways channel. Use Crestron Toolbox to set the CEN-GWEXERs RF channel. From the System Info window, select Functions > inNET EX Gateway from the menu bar. Refer to the Crestron Toolbox Help le for details. Acquire Devices to the Gateway Crestron inNET 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 congured 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 inNET EX device is placed in Acquire mode. To acquire an inNET 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 inNET EX and ER devices. NOTE: Acquire mode automatically deactivates after 1 hour. The timeout period can be changed from Crestron Toolbox.
