CPCI-3U Bus

The four-axis CPCI-3U is a smaller version of the -6U board. It connects to the backplane via two connectors: J1 and J2 (see figure above). Motion drive I/O is conveyed via J2, which is described in Chapter 4. Connector J1 is reserved as a computer bus, and is described in this section.

Backplane connector pins are referred to by numbered rows and lettered columns as shown below:
