SCSI Connector - J23
Connector J23 is a standard 68-pin SCSI connector mounted on the front
panel of the MVME172LX Embedded Controller. Table 5-7 lists the pin
assignments for J23.
VMEbus Connectors (P1, P2)
Two three-row 96-pin DIN type connectors, P1 and P2, supply the
interface between the base board and the VMEbus. P1 provides power and
VME signals for 24-bit addressing and 16-bit data. Its pin assignments are
set by the IEEE P1014-1987 VMEbus Specification. P2 Row B supplies
the base board with power, with the upper 8 VMEbus address lines, and
with an additional 16 VMEbus data lines. P2 rows A and C are not used in
the MVME172LX implementation. The pin assignments for P1and P2 are
listed in Table 5-8 and Table 5-9 respectively.
