The VMEbus has evolved over a period of more than
25 years to become the leading bus architecture in
open industrial applications. The specification is
an ANSI norm, the original specification has been
extended to become a draft standard VME64x
ANSI/VITA 1.1-1997. This draft standard includes the
specification for the 5-row DIN compatible connector
(IEC 61076-4-113) and for a centre connector
J0/P0 on 6U VME cards, which is identical to J3/P3
in CompactPCI
The 2.0 mm J0/P0 connector in VME64x systems
is used for additional I/O, for new high speed sub
busses or I/O for mezzanine modules, e.g. IP modules
on VMEbus boards. The connector is placed on the
Eurocard to work in combination with the non-metric
original VMEbus connectors DIN 41 612 type C
or the newer 5-row connector har-bus
mounting location and dimensions for the J0/P0
VMEbus connector (IEC 61076-4-101) is specified
in IEEE 1101.11. The VMEbus 2.0 mm connector
uses 5 columns of signal contacts and optional two
additional outer columns on either side for shielding.
All 95 signal contacts are user defined.

64. The
In VMEbus systems it is possible to use custom
connectors in the J0/P0 area (e.g. coax connectors).
To prevent problems with non-mating backplanes
it is strongly recommended to use front panel
keying. The IEEE 1101 documents J0/P0 can also
be used with rear transition modules for pluggable
I/O cabling. As mentioned above, the contacts on
this connector may be bussed. One example is the
ATM CellBus, which is in the process of being
standardised. The bus on J0/P0 connectors
might actually be a plug-on mezzanine backplane
rather than conducting traces integrated into the
backplane itself.
