The tables below list the signal assignments for the P2 connector on the
VXI bus. Pinouts are provided for both the slot 0 card [first table] and slots 1 to
12 [second table].
The VXI interface uses DIN 41612 connectors. Female connectors on the back plane, male style on the board side.
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.
The two tables above list the VXI P2 connector pin-outs and signal names.
The connector is a 96 pin DIN (41612) 3 rows x 32 pins @ IEEE 1014-1987.
The first table defines the pin-outs for Slot 0, the second table
describes the VXI P2 pin-outs for all other slots. The differences
between VXI and VME {VXI P2 additions} are listed below:
CLK10: 10MHz differential ECL Clock; Sourced from Slot 0 bused to
slots 1 to 12 on P2. Buffering occurs on the back plane, with each slot
appearing as a single destination (individually buffered).
TTLTRG0-7*: TTL Trigger Lines; Open Collector TTL lines used for
intermodule communication. Any module may drive or receive these
lines.
ECLTRG0-1: ECL single ended 50 ohm Trigger Lines; Any module may
drive or receive these lines. Used for intermodule timing.
LBUS00-11: Local Bus, Daisy chained keyed bus; may be either ECL
or TTL. Bused between adjacent slot only, I believe the keyed position
determines if two adjacent cards will talk to one another.
The VMEbus Address and Data signals require 3-State drivers and
receivers:
[A01 - A31], and [D00 - D31].

description is listed on the VMEbus page.
