Description
6 DB15
connector
Audio input: Audio: DB15 connector (with 2 rows of
pins) for audio input and a loop output at the sender.
The audio is extended to a remote receiver that has
both line as well as powered outputs (for driving
passive speakers). The DB15 audio I/O not only allows
Interface with line-level 3.5-mm mini stereo audio
sources (using adapter cable available from Black Box),
it also provides a more reliable and secure means for
the audio connection with its gold-plated D-Sub
connector with jack screws. The audio input level
supports a wide range of standards; it can be amplified
(for driving passive speakers), +4dBu (Pro-Audio), or -
10dBv (consumer line-level).

USB Type B connector
DR 1 input: Along with 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 keyboards or mice. 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).
9
USB Type B connector
USB STD input: This is a general-purpose USB port,
which goes through a hub in the sender and provides
two USB local output ports. It is also extended to the
remote receiver, where another hub provides the user
with four USB ports. These general-purpose USB ports
are labeled as KBRD 1, MOUSE 2, AUX 3, and AUX 4.
They support any type of low-speed or high-speed USB
devices. AUX 3 and AUX 4 are typically used for touch
screen displays, but support all other USB devices as
well.
