The switcher provides a standard 15-pole D-SUB female connector for connecting
VGA devices. Always use high-quality VGA cable for connecting sources and displays;
using a VGA cable where all the pins are wired (including the DDC channel's wires) is
highly recommended.

DVI-I Connector
UMX-HDMI-140 switcher provides a standard 29-pole DVI-I connector for input where digital and analog
pins are connected internally. Hence users can use the connector receiving DVI-A (analog video) and DVI-D
signals (digital video and digital audio) as well.
ATTENTION!
Only one (DVI-A or DVI-D) mode is available at a same time. You can use the Video Select
button to choose the input source.
Always use high quality DVI cable for connecting DVI devices.
