Interspace Industries CueEther-Receiver has been designed to work with their GlobalCue.Live free online software, using the PC app (iOS app coming soon) of i2Bridge that works with the Browser Cue-Light application.
Your presenters can control directly their own slides from their remote locations. Each unit has a pair of Dip switches that can be configured ( up to 4) for specific users.
The Technician's control PC will run the online GlobalCue.Live and the i2Bridge. i2Bridge will communicate with the online server and then send the data over your local network via a broadcast as UDP to the CueEther units plugged in to your computers.
Each CueEther will appear as a regular keyboard to your computer so it does not need an app running to receive the broadcasts from the i2Bridge and actions the commands to your computers.
