What is VXI test Chassis / rack VXIbus connectors & connections Modules & cards MXI

The pin connections for the P2 connector contain a variety of signals.

The P2 connector extends the capabilities of the backplane and provides additoonal connectivity to the modules or cards that may use them.

The pin connections differ between Slot 0, used for controllers, and the remaining slots 1 - 12 used for other cards and modules.

These pin connections are detailed in the tables below for slot 0 and then for slots 1 - 12.
