SBC I/O SECTION – BOTTOM SIDE
5.
All these connectors are on the bottom side of the panel I/O board. Their locations and pinouts match exactly the
corresponding connectors on the Athena III SBC. The pin numbering of these connectors, when facing the
connector, is reversed from the pin numbering on the male pin headers.

5.1 Ethernet

5.2 Input Power

The power signals on these connectors come from either the front panel input power connector via jumpers, or an
external switch, and connect to the power signals on the PC/104 connector of the Athena III SBC.

5.3 VGA

This connector provides a connection for VGA monitors. Note that while the DDC serial detection pins are
present, there is no 5V supply provided, nor are the old "Monitor ID" pins used.
