DIGITUS DS-55523 HDMI HDBaseT 3.0 Extender Set Instruction Manual

Introduction

The DIGITUS® HDMI HDBaseT™ 3.0 Extender Set enables uncompressed AV signal transmission in 4K/60Hz, 4:4:4 at 18 GB/s over a distance of 100 m via CAT 6A (or higher) cables. Both on the transmitter and on the receiver, there are two USB-A “Device” ports as well as a USB-B “Host” connection. This allows USB signals, e.g. fo KVM, USB data carriers etc., to be integrated on both ends and connected to the processing PC on the respective opposite end. Both devices can be switched between “Host” and “Device” mode using aDIP switch. The system enables bidirectional transmission of PoC (Power over Cable) and IR. Via RS232, both devices can be controlled separately. Analog stereo audio decoupling is also available. Another impressive feature is versatile eARC/ARC compatibility, which enables the connection to new and older audio devices such as AVRs (Audio Video Receiver). Two modes (ARC, S/PDIF) are available here, which can also be toggled very easily using a changeover switch.

Input & Output Switching

The Extender can switch to ARC/SPDIF mode by pressing the SELECT
button on the front panel of both transmitter and receiver. The HDMI OUT port of the transmitter can turn to LOOP OUT or AUDIO ONLY through the LOOP OUT/AUDIO ONLY Switch. The input and output routing are different for different sceneries. As shown in the diagrams below:

Scene 1: Set the Extender to SPDIF Mode. Then switch the LOOP OUT/AUDIO ONLY switch to right, the HDMI OUT port of the transmitter is set to AUDIO ONLY.
