Interconnect Signals
Introduction
This chapter provides the interconnection signals for the MVME712M and
P2 adapter board. The connectors described are listed in the following
table.
All front panel connectors have metal shells and jack posts that are
electrically connected to the front panel. If the front panel is electrically
connected to the chassis ground, then the shells and jack posts are
connected to chassis ground. This allows shielded cable to be used for
effective reduction of EMI and EMC problems.
