Powering the Repeater
FireRepeater 800™ is powered by the FireWire bus DC voltage, coming from host adapters or other FireWire devices.
FireRepeater 800™ is provided with a DC power input jack connector, which 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 via a bilingual to 4-pin cable
- when, 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 800™ can also be used to reinforce it. The FireWire bus voltage will adapt automatically when needed. A built-in diode avoids 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 15V DC, 1.5A. To match DC input connector, the jack plug of the DC adapter needs following dimensions and polarity:
