2.4 Setting the BoardID Switch (SW1)

You can use the BoardID command (0x20) to get the board’s unique

identifier. PCI-1751U has a built-in BoardID DIP switch (SW1), which

is used to define each card's unique identifier. You can determine the

identifier in the register as shown in Table 2.2. When there are multiple

cards on the same chassis, this BoardID setting is useful for identifying

each card's device number. We set the PCI-1751U’s BoardID switch to 0

at the factory. If you need to adjust this setting, please see below..
