WARNING
Before starting to mount or remove a personal computer
interface board, switch off the personal computer and its
peripheral devices, and disconnect their power supply
cables. Otherwise, there is a serious danger of electric
shock.
(1)Set the I/O addresses before installing the board. Set I/O base
addresses which do not overlap the I/O address areas exclusively used
by the personal computer and ISA expansion board. (See the figure
below.)
When using multiple personal computer interface boards, set the I/O
base addresses so that those addresses do not overlap each other.
(2)Remove the blank panel from the expansion slot of the personal
computer.
(3)Insert the interface board. Ensure that it has been completely inserted
into the ISA connector.
(4)Fix the metal brackets with screws.
CAUTION
Do NOT touch the edge terminals (the contacts that engage
with a mating connector) of the interface board.
