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.
