Powering the repeater
The Unibrain Firewire Repeater (FireRepeater™) is powered by the FireWire bus DC voltage, coming from host adapters or other FireWire devices connected with 6-pin cables.

The Unibrain Firewire Repeater (FireRepeater™) 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™ 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 need following dimensions and polarity:
