3.3 Setting the BoardID Switch (SW1)
BoardID settings are used to get the board’s unique identifier. The PCI-
1720 cards have a built-in DIP switch (SW1), which is used to define
each card's unique identifier. You can determine the unique identifier in
the register as shown in Table 3.2. When there are multiple identical
cards in the same chassis, the BoardID switch helps differentiating the
boards by identifying each card's device number with the switch setting.
This unique identifier has been set to 0 with the BoardID switch at the
factory. If you need to adjust it to other numbers, set SW1 by referring to
DIP switch setting.
