Compact PCI (CPCI) utilizes a card-type computer chassis, having a multi-pin backplane. The main advantage is smaller sizing and simplified access to electronics. There are two sizes of CPCI: -6U and -3U. The CPCI-6U is the larger of the two form factors and connects to the backplane bus via jumper connector J1. The CPCI-6U is described in this section.

CPCI-6U Main Board, Rear Panel Connector J1
NOTE: the CPCI XMP does not use the 64-bit extension.
CPCI-6U Expansion Board
Special Note: On CPCI-6U motion control systems having an expansion board, all computer bus data is conveyed via the main board's J1 connector, then relayed via the ribbon cable connector. Expansion boards also utilize a J1 backplane connector; however, it provides only power and ground to the expansion board.
