Overview
The IEEE1394 multimedia connection (also known as Fire Wire by Apple Computer, and iLink by
Sony) features hot swapping, high-speed performance, peer to peer communication and daisy
chained which can accept up to 63 devices connected simultaneously.
The idea of IEEE1394 standard is all other devices and peripherals that connected outside of PC
can simply plug into 1394 port instead of opening case and adding a circuit board. IEEE1394
standard is an important enabling technology for the emerging multimedia market.

Troubleshooting
If your system doesn’t work properly after connecting to a 1394 device, please turn off your
computer. Connect the auxiliary power connector (J5) to power supply and then restart again. If it
still doesn’t solve the problem, please refer to the specifications of your 1394 device. Check the
power consumption and make sure it doesn’t exceed 15W.
