Chapter 4 Operation

This chapter describes the operation of the PCI-1752U/PCI-1752USO.

The software driver provided allows users to access all of the card's func-

tions without register level programming. For users who prefer to imple-

ment their own bit-level programming, please refer to the information in

this chapter.

The PCI-1752/PCI-1752USO have a built-in DIP switch (SW1), which is

used to define each card's board ID. You can determine the board ID on

the register as shown on Table 4-1. When there are multiple cards on the

same chassis, this board ID setting function is useful for identifying each

card's device number through board ID. We set the PCI-1752/PCI-

1752USO board ID as 0 at the factory. If you need to adjust it to other

board ID, set the SW1 by referring to the Table 4-2.
