By default the MediaPort 300 enumerates as a generic webcam plus a non-echo cancelling speakerphone.
Via Extron PCS or SIS command the MediaPort can alternatively be configured to enumerate as a
speakerphone with echo cancellation (if using an external digital Signal Processor [DSP]), or can be
configured to enumerate as only a video or only an audio device.
Configure Windows for the MediaPort 300 as follows:
1.
Connect a USB-C cable from the MediaPort 300 rear panel USB-C port to a USB port on a Windows
PC. The required drivers install automatically. A message at the PC notifies you when driver
installation is complete.
2.

Open
Sound
Settings
(
