Atx Feature Connector (Cn13); Internal Keyboard Connector (Cn15) - Advantech PCA-6753F User Manual

2.16 ATX Feature Connector (CN13)

When the PCA-6753F is used as a standalone card, the main power
connector (CN9) is used. If the PCA-6753F is used with a passive
backplane, the main power connector (CN9) should not be connected.
This is because the card will be powered from the backplane.
(P8) 6-pin in backplane
(P9) 6-pin in backplane
The ATX adapter cable (provided) is used to connect the PCA-6753F
to the ATX power supply. The ATX adapter cable has different
connectors at both ends. On one end is the ATX 20-pin (female type)
which connects to the (male) ATX power supply source. The other
end has a 3-pin connector (female type) which connects to the ATX
feature connector (CN13) on the board itself. This end also has the
6-pin main power connector (P8) and a 6-pin connector (P9) which is
used when the board is mounted on a passive backplane.

2.17 Internal keyboard connector (CN15)

In addition to the PS/2 mouse/keyboard connector, an additional
external keyboard connector is provided.
For external keyboard pin assignments, see Appendix A.
