WIRELESS VIDEO EXTENDER, 8 PORT
User Manual

Introduction
The two-part DIGITUS® docking station transmits Full HD video signals to distances of up to
10 m. These video signals can be displayed on the HDMI® and VGA connection in parallel.
Additionally, audio signals can be picked up via the existing 3.5 mm jack socket because a VGA
cable cannot transmit any audio signals.
The transmitter and receiver unit elegantly merge into one unit thanks to the integrated
magnetic mount. When the connection is terminated, the docking station can be used as a
video extender.
The transmitter unit can be used within a 10-m radius of a notebook, tablet or smartphone and
extends your device by two graphic interfaces, two USB A ports, one SD / MicroSD card reader,
as well as one audio output.
Periphery devices such as a mouse, keyboard, printer or USB sticks can be connected to the
two USB A ports. The two memory card readers can be equipped with up to 2 TB.
The 8-in-2 DIGITUS® docking station is the perfect solution for bridging small distances in
offices or conference rooms with the most important interfaces for SOHO applications.
