Connector Pin Assignments
4.1 Overview
This chapter provides the pin assignments for the P2 connector and front panel port connectors
on the MVME761 transition module, as well as for the SCSI and PMC I/O connectors on the P2
adapters.
4.2 P2 Connector
Signaling and power from the host VMEmodules are received through connector P2, a 64-pin
DIN connector. Because the P2 adapter reroutes some of the signals, connector P2 on the
MVME761 transition module is not pin-for-pin compatible with connector P2 on the host
VMEmodules.
The pin assignments and signal mnemonics for the MVME761 transition module P2 connector
are listed in the following table.
