The SBR-RIO is a companion board to the CompactPCI® Serial peripheral card
SBX-DUB,
a 16-port xHCI SuperSpeed host controller. All USB 3.0 channels are passed across
the the SBX-DUB backplane connectors P3/P4 to the corresponding SBR-RIO receptacles rJ3/rJ4.
The CompactPCI® Serial rear I/O module SBR-RIO is equipped with
16 USB 3.0 receptacles in total. 8 ports are available from the back panel,
for attachment of external devices. Another 8 connectors are provided on-board,
for system internal usage.

The P2/rJ2 backplane connectors commit +12V system power
to a DC-DC converter on the SBR-RIO, which delivers +5V VBUS
to the USB connectors. 1.5A power switches, individually assigned
to each USB receptacle, prevent from potential damage caused by
overcurrent or even a short circuit represented by the external load.
EKF offers design support for custom specific variants of the SBR-RIO,
e.g. 16 x on-board connectors, or 16 x USB 3.0 rear panel
receptacles (8 HP assembly).
