case, all ports (both A and B) share the same
internal FireWire bus. So plan accordingly for your
FireWire resources. In addition, keep in mind that
if you connect a FireWire A device, it can slow the
entire bus to whenever the device is active on the
bus, so any connected FireWire B devices may not
be able to operate at their full performance levels at
all times. (If the FireWire A device is not active,
however, it won't affect the bus.)
FireWire is for computer connection only
The V4HD does not serve as a FireWire host: it
only operates as a FireWire client to a host
computer. This means that you cannot connect
cameras, hard drives or other client FireWire
devices to the V4HD when it is operating as a
stand-alone converter (with no computer
connected). When the V4HD is operating in stand-
alone mode, the only way to connect a camera to
the V4HD is through the standard video
connectors (analog, SDI, etc.) For more
information about stand-alone operation, see
chapter 11, "Standalone Operation" (page 93).
