1. INTRODUCTION
This UHD+Multi Format to HDMI Table Box is an HDMI, Mini-DP, and
USB-C switch with audio embedding and HDMI output. The table box is
designed to be placed on a table, or mounted to any typical table edge
using a clamp. The HDMI, Mini-DP, and USB-C inputs and HDMI output
all support resolutions up to 4K@60Hz (4:4:4, 8-bit). With the use of the
3.5mm audio input, stereo audio may be embedded into the HDMI
output as well.
Signal management features, such as automatic source switching based
on input signal detection, enable convenient hands-free operation.
Additional functionality such as advanced EDID management,

Start your preferred Telnet/Console client, or use the built in client
provided by most modern computer operating systems. After starting
the client, connect by using the current IP address of the unit and port
23 (if the communication port number used by the unit has not been
changed previously). This will connect us to the unit we wish to control
and commands may now be entered directly.
Note 1: If the IP address of the unit is changed then the IP address required for
Telnet access will also change accordingly.
Note 2: This unit’s network defaults to DHCP mode. The current IP address can
be verified using RS-232 if the Device Discovery software is not available. The
default communication port is 23.
