Operation Theorem

The operation theorem of the functions on PCI-9111 card is described in this chapter. The functions include the A/D conversion, D/A conversion, Digital I/O and counter / timer. The operation theorem can help you to understand how to manipulate or to program the PCI-9111.

4.1A/D Conversion

Before programming the PCI-9111 to perform the A/D conversion, you should understand the following issues:

∙A/D conversion procedure

∙A/D signal source control

∙A/D trigger source control

∙A/D data transfer mode

∙A/D Pre-trigger function

∙Interrupt System (refer to section 4.2)

∙A/D data format

Note: Because some of the A/D data transfer modes will use the system interrupt resource. The users have to understand the

interrupt system (section 4.2) at the same time.
