The PCI-1756 have a built-in DIP switch (SW1), which is used to define each card’s
board ID. When there are multiple cards on the same chassis, this board ID switch is
useful for identifying each card’s device number. After setting for each PCI-1756, you
can identify each card in system with different device numbers. The default value of
board ID is 0 and if you need to adjust it to other value, please set the SW1 by refer-
ring to Table 3.1.
Default Setting is 0.
