4.5.2 GPIO
These are standard 12-pin “mil-spec” sockets,
conforming to MIL-DTL-26482 (formerly
MIL-C-26482). A typical part-number is
02E-14-12S although the initial “02E” varies with
manufacturer.
Suitable mating connectors have part-numbers like
***-14-12P and are available from Amphenol, ITT
Cannon and other manufacturers.
The USB lines provide external host access to the internal USB memory
device. When power is sensed on pin J, an internal switch disconnects the
memory device from the internal circuitry and connects it to this socket.
