B. IEEE 1394
1. Outline of IEEE 1394 Standard
IEEE is a standard for high-speed serial interface called "Firewire" or "i.LINK"
Features of IEEE 1394 includes:
1. No host computer is necessary as communication between peripherals is possible.
2. IEEE uses daisy chain as a connection method, and maximum 63 connections are
possible.
3. IEEE transfers data with high-speed serial transfer with three kinds of transfer speed
including 100Mbit/s (noted as S100), 200Mbit/s (S200), and 400Mbit/s (S400).
CanoScan 9900F supports S100.
4. Hot plug is available.
5. Two kinds of connectors are available: 6-pin-connector with power supply and 4-pin-
connector without power supply
2. Signal Definition
CanoScan 9900F uses 6-pin-connector as an interface.
