XMP-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. For more information,
click here. 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:
