8-Bit I/O Addressing
To configure the board for an 8-bit I/O address refer to the figure below. Use the table to select the
jumpering for the appropriate upper and lower halves of the desired starting address (i.e., “3” and “0” =
hex address 30).
This jumper configuration ignores the state of the IOEXP signal in addressing the board. To use the
IOEXP signal refer to page 2-10.
