Powering the Repeater
 FireRepeater 400™ is powered by the FireWire bus DC
voltage, coming from host adapters or other FireWire devices
connected with 6-pin cables.
FireRepeater 400™ is provided with a DC power input jack
connector, that can be used when the FireWire connection
does not provide DC power. This happens typically:
- when the FireWire bus is converted to a 4-pin connection
- when, in 6-pin, no powering device is present, even from the FireWire interface. This is the case when using CardBus FireWire adapters or on some laptops with built-in interface.
Even if the FireWire bus is already powered, the DC power
input jack of the FireRepeater 400™ can also be used to
reinforce it. The FireWire bus voltage will adapt
automatically when needed. A built-in diode avoid any risk
of voltages conflict or reverse current flow.
 Recommended DC adapter must provide stable regulated output
voltage of at least 12VDC, 1 A or best 15VDC, 1.5A. To match camera DC input connector, the jack plug of the DC
adapter needs following dimensions and polarity:
