Chapter 2 Connecting Peripherals 25
2.18 AT power connector (CN20)
If you prefer not to acquire power through PCA-6751 Series' back-
plane via the gold H-connectors, CN20 also provides power input
connectors for +5 V, -12 V and +12 V. Pin 8 of the PS/2 power
supply can be used, too.
2.19 Keyboard and PS/2 mouse connector
(CN21)
The PCA-6751 Series' board provides a keyboard connector. A 6-pin
mini-DIN connector (CN21) on the card mounting bracket supports
single-board computer applications. The card comes with an adapter
to convert from the 6-pin mini-DIN connector to a standard DIN
connector and to a PS/2 mouse connector.
2.20 ISA gold fingers (CN22, CN23)
The 16-bit ISA gold fingers are used for connecting the PCA-6751
Series to an ISA passive backplane.
2.21 CompactFlash™ disk (CN24)
The PCA-6751 Series is equipped with a CompactFlash™ disk socket
on the solder side that supports the IDE interface for CompactFlash
cards. The onboard CompactFlash™ socket is designed to prevent
incorrect installation. Make sure that the system power is off when
installing and removing CompactFlash™ cards.
The CompactFlash™ card is defaulted as the E drive on your
PC.system.
