2. Use HDMI cables to connect the HDMI output ports from each computer to the correspond-
ing HDMI ports of the unit.
3. Use a USB cable (Type-A to Type-B) to connect a USB port on each computer to the respec-
tive USB ports of the unit.
4. Optionally connect a stereo audio cable (3.5mm to 3.5mm) to connect the audio output of
the computers to the AUDIO IN ports of the unit.
5. Connect monitors to the HDMI console ports of the unit using HDMI cables.
6. Connect a USB keyboard and mouse in the two USB console ports.
