Your V-FIRE is equipped with two R-BUS ports and two six pin FireWire ports. There is also
an input for an optional 12VDC or 16VAC power supply. Typically the V-Fire receives its
power from the computer via the FireWire BUS. If you are using your V-FIRE with a
computer that only has a four pin FireWire port, such as most PC laptops, then you will need
to use the optional external power supply.
