VL-1225/6 Analog Input/Output Board
10-Bit I/O Addressing
To configure the board for a 10-bit I/O address refer to the figure below. Use the table to select the
jumpering for the appropriate upper, middle, and lower hex digits of the desired starting address (i.e., “1”
and “3” and “0” = hex address 130).
This jumper configuration ignores the state of the IOEXP signal in addressing the board. To use the
IOEXP signal refer to page 2-10.
