Serial Port 1/Console Connector - J25
A DB25 socket connector located on the front panel of the MVME162P4
provides the interface to Serial Port 1. The pin assignments for the
connector are as follows.
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 MVME162P4 implementation. The pin assignments for P1and P2 are
listed in Table 5-6 and Table 5-7 respectively.
