The Expansion Board is connected over two 2.0 mm, 44-pin flat band
cables. The pinout of the Carrier Board header connectors X30 and
X31 is given in the following table. Using a customer-specific
Expansion Board instead of the standard Expansion Board is also
possible given the removable connection via flat band cables. The
connector X30 contains the signals for the CompactFlash card. The
voltage pin CF_VCC can only be used for the CF card because it is
switched on or off depending on the operating status of the socket.
