DL-SCU21C Quick Guide

The DL-SCU21C is a 2x1 HDMI 2.0b auto switcher featuring one HDMI input, one USB-C input and
one HDMI output. The USB-C input supports video, data (USB host) and power charging up to 40w.
There is a built in 2 port USB 3.0 hub that is backwards compable with USB 2.0 and USB 1.1 formats.
This switcher supports video resoluons up to 4Kx2K@60Hz 4:4:4, HDR, and mulchannel audio. In
addion to passing nave EDID informaon from the display to an input on the switcher, there are
mulple built-in EDID sengs to choose from to simplify an installaon. The switcher will de-embed
2 channel analog audio for audio reinforcement which is de-embedded the HDMI output. The devices
switching funcons can be controlled via RS232 and front panel control buons can be congured
to control 3rd party devices such as TV display via CEC or RS232. For a list of available RS232 control
commands, please see the owners manual for this product located online at www.libav.com.
When in auto-switch mode, the switcher will switch to an input as soon as a new source is connected.
When the acve source is removed, the switcher will select the rst source on the lowest numbered
input. When switching between HDMI and USB-C video inputs, the USB B Host port will follow HDMI
and USB-C will act as a USB host disengaging USB B Host control.
