The tripp lite netcommander usb server interface unit (siu) connects to the hd15 port and usb port on a computer/server, and converts them to a single rj45 connector. ordinary cat5e patch cables can then be used to connect the server to the switch ports on a tripp lite b070 / b072-series netcommander cat5 kvm switch. use of cat5e cables frees up space in the installation that would ordinarily be filled by traditional, thicker kvm cables.
