Selecting I/O Boards

After selecting the form factor for a system, you need to choose the I/O boards

that will connect the target PC to the hardware being tested.

You already know the type of signal connections you require for an application.

For example, you might need 6 A/D channels, 2 D/A channels, 1 PWM, and 1

counter. Also, you need to know which I/O board or boards will give these

connections and whether they are compatible with the base form factor, and

supported by xPC Target.

Table 1-2, Compatibility of Base System and I/O Form Factors shows the

compatibility of base system form factors with I/O board form factors. This

table helps you to quickly determine what I/O types are available for your

chosen system. For example, if you have a PCI system, I/O boards using the

PCI, PC/104+, PMC, and IP-Module form factors would all be compatible.
