PXI Connector P2 Pin Out and Signal Names

The PXI connector P2 [J2] pinout is provided below for the Peripheral slot. The PXI P2 connector pinout for the System slot is provided on its own page.
The pinout is also the same as the CompactPCI pinout. cPCI is electrically identical to the PCI specification, it uses the same signals. However some signals have been added in addition to the PCI specification.
Refer to the PXI P1 pinout page for P1/J1 Pin outs.

The PXI Peripheral Slot pin out for P2/J2 is provided above. cPCI is electrically identical to the PCI specification, it uses the same signals. However some have been added in addition to the PCI specification. Additional notes:
The number sign in the pinout table above refers to: "A # symbol at the end of a signal name indicates that the signals asserted state occurs when it is at a low voltage. The absence of a # symbol indicates that the signal is asserted at a high voltage.
The V(I/O) pins are un-named in this table. In a +5 volt system the V(I/O) pins are +5volts, in a +3.3volt system the V(I/O) pins are +3.3 volts.

cPCI uses 2mm 'Hard Metric'; IEC 1076-4-101, a number of different pin arrangements. Normally the outside Ground rows (which are compression pins) 'Z' and 'F' are not counted as pins. OEM pin numbering may be by cPCI or in accordance with IEC 61076-4-101 (which is reversed). The term "Hard Metric" only means that metric dimensions are preferred ~ with-out regard to inches.

cPCI 2mm connectors mating distances [12.50mm] matches the 96 pin DIN 41612 connectors used with other EuroCard packaging [IEC 273 or IEEE 1101, 1101.10], like VMEbus. FutureBus connectors, which also use 2mm style has a mating distance of 10mm, and is not compatible with cPCI connectors.

The connector styles below are counting signal pins (not the ground rows), as indicated on many data sheets:

Type A connector; 110 pins, Keyed (J1/J4),([25 rows x 5 columns] - [3 rows x 5 columns of Key])
Type B connector; 110 pins (J2/J5), [22 x 5]
Type B connector; 95 pins (J3), [19 x 5]. This is also used as P0 with VME64
Type C connector; 55 pins [11 x 5]
Type AB; 95, 110, or 125 pins

There are other types:
Type L connector; # contact cavities to accept power insert contacts
Type M connector; # contact cavities to accept power insert contacts/with half the connector having normal pins
