Chapter 5: USB Extension
5. USB Extension
Modern computers and laptops no longer ship by default with an RS-232 serial port.
What used to be a DB9 male port has now become a USB port. Any needed RS-232
serial communications now require the use of a USB to serial adapter (DB9 or DB25).
Most computer devices, however, have one if not several USB ports. The
MediaCento can use a USB connection and extend it over the network using the
same network connection as the HDMI video.
Included on the MediaCento transmitter is a USB Type B female connector, which
will install in Windows as a USB 2.0 Hub when connected to a USB port on a
computer. The receiver has four USB Type A female connectors used for remote USB
extension over IP.
Although the MediaCento is not a KVM switch, you can use it to extend a remote
USB keyboard and mouse to control the local CPU. The receiver USB ports also
support USB extension for Jump drives or for a USB to RS-232 converter cables. For
example, the Black Box IC199A-R3, USB to DB-9 Male serial adapter cable, works
flawlessly to give a remote USB extension over the network to an RS-232 port.
To install the MediaCento in a point-to-point (Unicast) configuration, you must make
all the physical connections first, including the USB devices. Set the ID selector to
the proper setting, then power-on the unit and associated devices. A “Starting USB”
message will display in green letters on the remote screen shortly after power-on.
To install the MediaCento in a point-to-multipoint (multicast) setup, the USB devices
are not available for simultaneous access. You must configure one receiver at a time.
For each receiver that you want to access USB devices from, simply hold down the
F1 button for three seconds, and the MediaCento will transfer control to that unit.
