The table below lists the signal assignments for the P1 connector on the
VXI bus. Pinouts are provided for both the slot 0 card and slots 1 to 12
[which are identical].
The VXI interface uses DIN 41612 connectors.
A listing of manufacturers which produce DIN 41612 connectors may be
found on the VME page; a link is provided below the pin out table.

Both the VMEbus and VXI bus use the same P1 connector, the pin-outs and
signal names are the same. The connector is a 96 pin DIN (41612) 3 rows x
32 pins @ IEEE 1014-1987. The pin-out for either bus is listed in the
table above. The latest VMEbus spec added two additional rows, but I'm
not sure that the up-grade has hit the VXI spec yet. Because both bus
types can use the same P1 connector, VME cards may be used in a VXI bus.
How ever I do not believe VXI cards work in a VMEbus chassis, because of
the P2 differences.
The VMEbus signal types for P1 and P2 connectors are listed below:
Open collector signals which require Open Collector drivers and
receivers:
ACFail, BBSY, BERR, DTACK, IACK, SERDAT, SYSFAIL, SYSRESET, [IRQ1 -
IRQ7], and [BR0 - BR3].
Three-State signals which require 3-State drivers and
receivers:
AS, DS0, DS1, DTACK, RETRY, IACK, LWORD, WRITE, [AM0 - AM5], [A01 - A31],
and [D00 - D31].
Totem-Pole signals which require Totem-Pole drivers and
receivers:
BCLR, SYSCLK, SERCLK, IACKIN, IACKOUT, [BG0IN - BG3IN], [BG0OUT -
BG3OUT].
