[olpc-help] External DC Power Jack Specs

[Steve Holton]

Jim-

The XO power jack defines an interface. There are physical
characteristics and electrical characteristics.
The Physical Characteristics are as Richard stated before:

 1.67mm Center pin     (or 1.65 on the Wiki)
 5.5mm Outer barrel    (or 6mm on the Wiki, 4.75 or so from Richard)
 11mm contact length  (or 9.5 as Richard states above)

A full technical description with tolerances in not available. The
best I can do is reference the de-facto standard Richard gave us:
Digikey part # CP-2195-ND

When I get hardware in hand, I'll seek out the original manufacturer
of the part. I'm sure they have a story to tell.

We should probably include in here something about the coaxial cable
they're using for power, if that was selected for physical
characteristics. Many questions here. Again, I'll know more when I see
one for myself.
