Note. The USB interface board is set to USB1.0 mode in order to permit maximum flexibility in the
choice of components used for the cable and connectors that are used between the monitor and the
USB host or KVM switch. USB specifies maximum cable length for USB 1.0 and 2.1 devices as 16 feet,
5 inches. This maximum length can be used if 100 Ohm low capacitance shielded twisted pair cable is
used. Reduce length if the cable does not fully meet the USB specifications for best results.
