Backplane
Connections
The breadboard module allows you to interface your custom circuits to any
standard C-size VXIbus backplane (connectors P1 and P2). This enables you
to access the backplane control signals, data lines, address lines, trigger buses,
and power supplies.
Backplane Connector
Pins
Table 2-1 lists backplane connectors P1 and P2 pins which connect to the VXIbus
backplane. Address memory or anything requiring A24 - A31 cannot be accessed
because there are no pins for the center row on the P2 connector. Data wider than
16-bits cannot be sent because the D16 - D31 lines are also on the center row.
