MECHANICAL DRAWING A mechanical drawing of the Athena III panel I/O board connector layout is provided below. The drawing shows the top side of the panel I/O board with the relative connector locations. All I/O connectors are located on the board so that there is sufficient room to install all connectors without interference with any other connector or mounting hole. -

These connectors are on the bottom side of the panel I/O board, outside the PC/104 outline. They do not connect to the Athena III SBC. They are used for other internal connections and functions. These connectors are 0.1” pitch male pin headers. -
Page 14: Power Section
The +12V input option jumper is also a 0-ohm ¼ watt T/H resistor used to route +12V from the Vin pin to the +12V pin on the Athena III power connector. If the Vin voltage is not +12V then the resistor is cut away to isolate the +12V pin on the Athena III primary power connector.
