2.19 CPU Fan Power Supply Connector (CN19)

The PCA-6751/6751V is equipped with the low power dissipation

Intel MMX CPU. With only a heatsink, it will work normally at

temperatures up to 60° C. At temperatures greater than 60° C, a fan is

needed. A CPU fan power supply connector is provided

(+5 V / +12 V input) in addition to the CPU power supply.

This provides power supply to the optional CPU cooling fan. This

connector is only available when +5 V, -12 V and +12 V power is

supplied to the board.

Warning! Before making the connection, make sure the

2.20 AT Power Connector (CN20)

If you prefer not to acquire power through PCA-6751/6751V's

backplane 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.

2.21 Keyboard & PS/2 Mouse Connector (CN21)

The PCA-6751/6751V 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.

The 16-bit ISA goldfingers are used for connecting the

PCA-6751/6751V to a ISA passive backplane.

voltage is absolutely correct and matched with the
