The Crestron CEN-GWEXER is a 2-way RF wireless transceiver module designed to add robust, license-free wireless communication capabilities to Crestron control systems. It functions as a gateway, enabling bidirectional data exchange between a wired Crestron processor and wireless devices such as Crestron handheld remotes, occupancy sensors, thermostats, and other RF-enabled peripherals. Operating in the 900 MHz or 2.4 GHz ISM band (specific to the model), it provides a reliable wireless link that penetrates walls and obstacles effectively, making it suitable for whole-home or building automation where running control wires is impractical or too costly. The module typically connects to a compatible Crestron processor via a serial or Cresnet interface, seamlessly integrating wireless devices into the overall control program.

The transceiver is engineered for reliability in residential and commercial environments. It employs frequency-hopping spread spectrum (FHSS) or other advanced modulation techniques to avoid interference from other wireless devices and ensure secure, stable communication. The module can often support multiple wireless devices simultaneously, creating a mesh network for extended range and redundancy. Installation involves connecting the module to the control system and placing it in a central location for optimal coverage. Configuration is handled through Crestron's programming software, where wireless devices are paired and their commands are integrated into the system's logic.

By providing a dependable wireless bridge, the CEN-GWEXER significantly expands the flexibility and scope of a Crestron automation system. It allows for the deployment of wireless keypads in retrofit projects, the addition of wireless sensors for environmental monitoring, and the use of familiar handheld remotes for system control, all without the need for extensive new wiring. This makes it an essential component for modern, scalable smart home and building solutions.
