Connector P2 and J11 Interconnect Signals (MVME712 x )
Connector P2 on the MVME712-12 or MVME712-13, or connector J11 on the
MVME712A or MVME712AM, receives the signals from the LCP2 adapter.
Each pin connection, signal mnemonic, and signal characteristic for the
connectors is listed in
Table 3-12 .
9 R+ RECEIVE + (Input) - a data input sourced by the
MAU.
10 +12VF +12 Vdc Power - fused on MPU board.
11-20 Not used.
