Additional PXI notes:
PXI stands for Compact PCI for Instrumentation Bus |
The connector types 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 connector; 95, 110, or 125 pins
There are other stlyes:
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
