2 Form Factors

2-12

Many vendors of PCI I/O boards offer a compatible board in the CompactPCI

form factor. Nevertheless, the range of available CompactPCI I/O boards is still

smaller than the range of available PCI boards for the desktop PC or

rack-mount PC.

We recommend that you use PMC I/O boards. You can use these boards in

CompactPCI, desktop PC, rack-mount PC, or PC/104 systems by plugging

them into a passive carrier board for the corresponding form factor. This

flexibility reduces your risk when investing in expensive I/O boards.

CompactPCI systems cannot be equipped with ISA I/O boards at all, and this

may be a problem if a special, usually legacy, I/O connectivity is required.

You can use the following standard I/O board form factors in CompactPCI

systems:

• CompactPCI

• PMC — Through a passive CompactPCI carrier board

• PC/104+ — Through a passive CompactPCI carrier board

• IP-modules — Through an active CompactPCI carrier board

Advantages

The advantages of selecting a CompactPCI computer for your target PC are

• A well designed, clean specification that standardizes all components,

including the chassis

• Smaller physical dimensions than desktop or rack-mount PCs

• Rugged design for use in harsh environments

• High I/O expandability

• Easily accessible I/O connectors

• Very high level of maintainability
