Connectors
The MVME2300SC interfaces to the VMEbus via P1 and P2, which are
implemented with the three-row 96-pin connectors specified in the IEEE
P1014-1987 VMEbus specification. The board also draws +5V, +12V, and
12V power from the VMEbus backplane through these two connectors.
−
(The 3.3V supply is regulated on-board from the +5V power.)
Front panel connectors on the MVME2300SC include an RJ45 connector
for the Ethernet 10BaseT/100BaseTX interface, and a 9-pin DB9
connector for the asynchronous serial debug port.
The MVME2300SC is equipped with two IEEE 1386.1 PCI Mezzanine
Card (PMC) slots. The PMC slots are 64-bit capable and support both
front and rear I/O. Pins 1-32 of PMC slot 1 connector J14 are routed to
rows C and A of the 3-row P2 connector. Pins 1-32 of PMC slot 2
connector J24 are likewise routed to rows C and A of connector P2.
Additional PCI expansion is supported with a 114-pin Mictor connector
(J6). This connection permits the stacking of one or two PMCspan dual-
PMC carrier boards on the MVME2300SC for increased I/O capability.
Each PMCspan board that you add requires an additional VME slot.
Pin assignments for the connectors on the MVME2300SC are listed in
Chapter 5.
