3.2.1 Setting the BoardID Switch (SW1)BoardID settings are used to set a board’s unique identifier when multiple
identical cards are installed in the same system.
PCI-1718 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 3.1. If there are multiple identical cards in
the same chassis, the BoardID switch helps differentiate the boards by
identifying each card’s device number with the switch setting. The Boar-
dID switch’s unique identifier has been set to 0 at the factory.
If you need to adjust it to other numbers, set SW1 by referring to DIP
switch settings below.
