Model U97-ULTRA
general-purpose USB ports support any type of low-speed or high-speed USB
devices. AUX
support all other USB devices as well.
DR1 & DR2 – These are two "Direct" extension USB ports. The corresponding

USB port on the PC is directly extended to a remote receiver with no hubs or
other functions in the path. The PC's USB port that is extended via DR1 or DR2
behaves exactly as if it were connected directly to the target device at the
remote. These "Direct" USB port extensions are perfect for high data rate
devices, such as video cameras, storage media, printers and chart recorders.
They do not support low-speed "Human Interface" devices, such as keyboard
or mouse. Having a dedicated path from the target device to the PC ensures
full channel bandwidth availability in the interface (as opposed to several
devices sharing one port on the PC via a hub).
Serial RS-232 – Bi-directional extension of RS-232 data.

Both the sender and the receiver have built-in power supplies with standard IEC320 jacks
(no external power bricks). The sender includes 6 ft cables for connection to the PC (3x
USB, 2x VGA, 1x DB15 audio). The sender also includes rack-mount front panel. The
receiver includes a metal guard that covers all the connections, thereby eliminating the
need for a separate utility box.
Both the sender and the receiver have DB15 output connectors for the sound so that
standard 4 or 8-Ohm passive speakers can be directly connected at both ends.
