Set the I/O port addresses with the DIP switch as shown in the following table. Be
sure to set a range of addresses that isn't being used by another device in order
to avoid a conflict. (A pin setting of 0 is OFF and 1 is ON.)

Note There are some boards marketed that cannot distinguish between I/O port
addresses 200 through 2FF and addresses 600 through 6FF. If one of these
boards is allocated address 2jj, it will occupy address 6jj as well.
To avoid any possible conflicts when assigning an address between 600 and
6FF, be sure to assign an address that corresponds to an unused address
between 200 and 2FF. (For example if 6A0 to 6A7 are selected, make sure that
2A0 to 2A7 are unused.)
The ISA Board must be installed into one of the personal computer's expansion
slots (ISA slots). When installing the board, turn off the computer's power and
take precautions against static electricity. Refer to the computer's user's manual
for detailed installation procedures.
