iLink is FireWire without power pair lines.  It has the same 4 signal 
lines (2 pairs) but missing power.

See: http://www.vxm.com/21R.49.html 
Picture on http://www.vxm.com/Ss21st_1.gif shows crossection of FW 
cable. Remove two red power lines and you'll have iLink.


IEEE-1394 and FireWire are the same. FW was introduced by Apple and then
adopted as IEEE standard few years later.

Cheers,
