Surge protection device recommended
This product contains sensitive electrical components that may be
damaged by electrical spikes , surges , electric shock , lighting strikes,
etc. Use of surge protection systems is highly recommended in order
to protect and extend the life of your equipment
1. 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. for
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 a
DIP 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.
