The CEN-RFGW-EX is a 2-way RF gateway/transceiver designed to enable communications and management for a complete infiNET EX® wireless network of dimmers, keypads, remotes, shades, thermostats, door locks, and other devices. The CEN-RFGW-EX links the infiNET EX network to a Crestron® control system via high-speed Ethernet. "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. Built-in Dynamic Frequency Allocation continuously monitors RF conditions, automatically selecting the clearest channel to prevent interference from neighboring networks, cordless phones, and microwaves.

infiNET EX®
Ultra-reliable infiNET EX wireless technology provides steadfast 2-way RF communications throughout a residential or commercial structure without the need for physical control wiring. Employing a 2.4 GHz mesh network topology, nearly every infiNET EX device on the network functions as an expander, passing command signals through to every other device within range (approximately 150 feet or 46 meters indoors), ensuring that every command reaches its intended destination without disruption. Each infiNET EX device that is added to the network effectively increases the range and stability of the entire network by providing multiple redundant signal paths.[1]

Easy Setup
Setting up a complete infiNET EX network is simple, utilizing dynamic discovery to locate and acquire each RF device automatically. At all times, the CEN-RFGW-EX monitors each device on the network, ignoring any other 2.4 GHz signals, and reconfiguring the entire network automatically in response to new sources of interference and other changes in RF conditions.

Up to 100 infiNET EX devices can be linked to a control system via a single CEN-RFGW-EX gateway.[2] Additional gateways may be installed to support more devices, with up to 16 gateways possible in a complete system (RF conditions allowing). Wireless expanders (model CLW-EXPEX or GLA-EXPEX[3]) may be added wherever needed to extend the network by filling in gaps between devices.[4]

Handheld Remote Gateway
The CEN-RFGW-EX also provides a wireless gateway for Crestron MLX-3 and MTX-3 Handheld Remotes[3]. Up to 6 remotes can be associated with a single gateway.[2] Each wireless connection is monitored continuously, diligently keeping track when any remote goes to sleep or wanders out of range, restoring communications seamlessly when it reappears on the network.

Single-Wire Hookup
The CEN-RFGW-EX gateway communicates with a control system over Ethernet and gets its operating power over the same Ethernet connection using PoE technology. PoE (Power over Ethernet) simply requires the presence of an 802.3af or 802.3at PoE power source. Crestron offers the PWE-4803RU PoE Injector, which connects inline with the Ethernet cable, allowing for installation at any 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-RFGW-EX-PWE.

Crestron also offers Ethernet switches with built-in PoE (models CEN-SW-POE-5, CEN-SWPOE-16, and CEN-SWPOE-24[3]), 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 individual PoE Injectors.
