1. Product Introduction
The SCU41T-TB 4x1 conference tabletop box is a multi-format switcher with three
HDMI inputs, one USB Type-C input, one HDMI output and one HDBT output. The USB
Type-C port provides charging for source device up to 60w. The box supports HDMI
and USB-C video resolutions up to 4K@60Hz 4:4:4 and multichannel audio. In addition
to passing EDID information from the display, there are multiple built-in EDID settings to
simplify an installation. The kit supports auto switching, auto display device control,
USB 2.0+3.0 signal extension and Ethernet signal extension. All signals of video, audio,
control and USB can be transmitted over a single CATx cable up to 70m. The HDBT
output supports bi-directional 24V PoC, allowing the compatible receiver (e.g. SCU42T-
CODEC-R, sold separately) to draw power from the tabletop box over the CATx cable.
The SCU41T-TB also supports front panel button control, Web GUI, CEC and RS232
control.
