3.3.3 1394 Header Design

The 1394 header consists of a keyed shrouded (blue for 1394A, red for 1394B) 2x10 stake pin

header (100-mil pitch) with key locations on pin 9. Note that pin 1 location relative to shroud key

is opposite that of the USB header shown in Figure 7 and is intended to prevent 1394 cables from

attaching to USB headers and visa versa.
