P2 Adapter Board
The following paragraphs provide the interconnection signals for the
connectors on the P2 adapter board.
P2 connector
Connector P2 is a standard DIN 41612 triple-row, 96-pin connector. Each
pin connection, signal mnemonic, and signal characteristic for the
connector rows A and C are the same pin-for-pin as connector P2 on the
MVMExxxx processor module. Row B has only +5 Vdc and ground
connected on the P2 adapter.
J2 connector
Connector J2 on the P2 adapter board and connector J2 on the
MVME712M are 64-pin DIN connectors that are the same pin-for-pin.
Each pin connection, signal mnemonic, and signal characteristic for these
connectors is listed in the following table.
