FireWire Connection
The Onyx 400F is equipped with two 6-pin FireWire
connectors and comes with a 6-pin to 6-pin FireWire
cable. This works with Macintosh laptops and desktops,
and most PC desktops with a built-in FireWire connec-
tor or with a PCI or PCMCIA FireWire card added.
Many laptop PCs have a 4-pin FireWire connector. If
this is the case, you will need to purchase a 6-pin to 4-
pin FireWire adapter cable. These are readily available
at computer stores or online.
