Chapter 2: Overview
2. Overview
2.1 Introduction
The Presentation Switcher - HDBaseT, 8 x 2 is a powereful 8-input, 2-output, multiformat converter, switcher, scaler, and extender with built-in 4K scaling, in a compact
1U rack enclosure. It offers three HDMI inputs, two VGA inputs with stereo audio, one
DisplayPort input, (2) HDBaseT inputs, one HDMI output and one HDBaseT output. The
HDBaseT inputs and outputs use bidirectional IR passthrough, RS-232 passthrough, and
Power over HDBaseT (PoH).
Any of eight inputs can be routed into any of two outputs seamlessly. The switcher
supports up to 4K @30 Hz video resolution and can scale output from 480p to 3840 x
2160 @ 30 Hz regardless of the input video resolution. Plus, you can mix two micropone inputs into any of the eight inputs for output. One balanced stereo audio breaks
out from HDBaseT output.
You can control the switcher via front-panel buttons, RS-232 RS-485, LAN, Web UI,
and IR remote. Control the switcher directly or via a third party control system.
It provides the complete API commands for integration. It also supports bi-directional
USB passthrough for use in KVM at either end of the link.
This 8 x 2 seamless 4K scaling presentation matrix switcher is your perfect choice
for collaboration presentation in conference and education field.
