Rear Transition Module

P3 Interconnect connector
The P3 connector on the XVME 990-VR7 is used to pass the P2 signals through to an adjacent XVME-
977 or XVME-979 drive card. It has the same pin out as rows A, B, and C of P2. The required
interconnect 64-pin cable is included with the XVME-977 or XVME-979 modules. Note since the cable is
only 64-pins, the row-b of this connector is not carried across but is bused on the VMEbus back plane.
Table 5-4 shows pin out of the interconnect of VMEbus P2 to P3.
