Backplane Connectors

CPCI-6U Expansion Board

Location	Function	Pinouts
J5	Axes 8-11	pinouts
J4	Axes 12-15	pinouts
J3	User I/O	pinouts
J1	Bus	pinouts

On CPCI-6U controllers using backplane I/O, drive signals are conveyed through connectors J3, J4 and J5.

For main boards, axes 0-3 are controlled through connector J5. Axes 4-7 are controlled through connector J4. User I/O is provided through connector J3.

On expansion boards, axes 8-11 are controlled through connector J5. Axes 12-15 are controlled through connector J4. User I/O is provided through connector J3.

On both main and expansion boards, connector J1 is reserved for computer data bussing. For more information on the CPCI-6U data bussing, click here.
