2P3 PMC Module Slot User I/O
64 bits of configurable user I/O are provided from the VME P2 connector directly to
the PMC 1 and PMC 2 Module slot positions. All 64 bits may be routed to PMC 1,
leaving 0 bits of user I/O for PMC 2. Alternatively, 32 bits may be routed to PMC 1
and 32 bits to PMC 2. In the latter case, PMC 1 will utilize the upper VME P2 sig-
nals—VME P2 A[32..17] and VME P2 C[32..17]—while PMC 2 will utilize the
lower VME P2 signals—VME P2 A[16..1] and VME P2 C[16..1]. The signals are
available on the J1004 connector of PMC slot 1 and the J1104 connector of PMC
slot 2. If all 64 bits of user I/O are routed to PMC slot 1, it utilizes all 64 signals of
the VME P2 connector. In this case, all 64 signals are available on the J1004 connec-
tor of PMC slot 1.
3.2.3.1 2P3 PMC Module Slot Pinouts
This section provides the pinouts of the 64 PMC User I/O signals that can be brought from
PMC Module
Slot 1
and
Slot 2
to the VME P2 connector of the 2P3 PMC Carrier Board.
Figure 3-5
shows the pin orientation of the PMC Module Slot connector used to
install PMC Modules onto the top side of the circuit board (USPIIe, USPIIe-USB,
USPIIe-Gb, USPIIIi, or USPIIIi-OPT).

2P3 PMC Module Slot Connector Pin Orientation
Note:
User I/O is directed to PMC 1 and PMC 2 Modules through solder-bead
configurations (see
Table 3-7
on page 3-15).
Note:
PMC Module
Slot 3
transmits no I/O through the VME P2 connector of
the 2P3 PMC Carrier Board. (See
Figure 3-2
on page 3-2).
