The MVME167P has a 20-pin connector (J3) mounted behind the front
panel. When the MVME167P board is enclosed in a chassis and the front
panel is not visible, this connector enables you to extend the Reset, Abort
and LED functions to the control panel of the system, where they remain
accessible. The pin assignments for J3 are listed in
Table 6-1. Remote Reset Connector J3

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 eight VMEbus address lines,
and with an additional 16 VMEbus data lines. P2 rows A and C are not
used in the MVME167P implementation.
