MediaPort®300 • Setup Guide
The MediaPort 300 is an HDMI and audio to USB scaling bridge that interfaces between pro AV
equipment and computer-based video conferencing and recording software. Incoming HDMI video is scaled and output via USB to a
host computer. Bi-directional audio is supported over the USB bus, including one stereo pair from the PC for application playback and
far-end communication audio, and one stereo pair to the PC for near-end local audio to be sent to the far end. Setup and control are
available via a front panel USB-C Conguration port and a rear panel Ethernet port. Simple Instruction Set (SIS™) commands and the
Windows®-based Extron Product Conguration Software (PCS) simplify initial conguration and real-time control. The 1-inch (2.54 cm)
high, half rack wide, 6 inches (15.24 cm) deep enclosure can be optionally mounted to a rack shelf, or under or through furniture.

• Loop Out — Video is passing to a sink connected to the HDMI loop out connector.
• Loop HDCP — The signal out of the HDMI loop out is HDCP encrypted.
DUSB Status LEDs — Indicates the status of the USB stream, as follows:
• Host —
• Lit steadily — The MediaPort 300 is connected to an active USB host.
• Blinking — The USB host connection is suspended.
• Unlit — No USB host connection detected.
• Audio Return — Lit steadily indicates that audio is being returned from the USB host.
• Video Send — Lit indicates that video is being output to the USB host.
• Audio Send — Lit indicates that audio is being output to the USB host.
Operation
Power
The MediaPort 300 can be powered in either of two ways:
• Locally, from the included external 12 VDC power supply and via the power connector (see figure 1, Ion page 1).
• Remotely, receiving PoE+ via the LAN/PoE+ port (see G), either from the network switch or from an optional PI 140 Power
Injector.
When power is applied, the MediaPort 300 runs a series of self-tests that cycle through all front panel LED indicators. The
MediaPort 300 then starts up. It can take approximately 30 seconds for self-test and system startup to complete.
Configuring the MediaPort 300
The MediaPort 300 can be congured through a host connected to the LAN or the front panel USB-C Cong port using Extron PCS,
the embedded HTML pages, or using SIS commands (see the MediaPort 300 User Guide at www.extron.com for more information).
ATTENTION:
• Do not power on the MediaPort 300 until you have read the ATTENTION in the “Power Supply” section of the
MediaPort 300 User Guide.
• Ne branchez pas le MediaPort 300 avant d’avoir lu la mise en garde dans la section « sources d’alimentation » du
MediaPort 300 User Guide..

MediaPort 300 USB Enumeration
The host PC or Mac detects the MediaPort 300 and installs generic USB UVC (universal video codec) and
UAC (universal audio codec) drivers, a process known as “enumerating”
.

Speaker Pop-up Menu
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.

2. Loosen the connection mounting screw from the panel enough to allow the LockIt lacing
bracket to be placed over it (2). The screw does not have to be removed.
3. Place the LockIt lacing bracket on the screw and against the connector (3), then tighten the screw
to secure the bracket.
ATTENTION:
• Do not overtighten the connector mounting screw. The shield it fastens to is very
thin and can easily be stripped.
• Ne serrez pas trop la vis de montage du connecteur. Le blindage auquel elle est
attachée est très n et peut facilement être dénudé.
4. Loosely place the included tie wrap around the connector and the LockIt lacing bracket as shown (4).
5. While holding the connector securely against the lacing bracket, use pliers to tighten the tie wrap, then remove any excess length (5).
