P2 Adapter Preparation (Five-Row)

The MVME761 transition module uses a five-row P2 adapter to transfer the synchronous and asynchronous serial, parallel, and Ethernet signals to and from the MVME2600 series VME module. The P2 adapter has a

68-pin female connector (J1) that carries 16-bit SCSI signals from the MVME2600. (To run SCSI devices, you may install an optional front panel extension, MVME761EXT, next to the MVME761. The panel extension supplies both 8- and 16-bit SCSI.) The P2 adapter for the MVME761 also supports PMC I/O via connectors J3 and J4.

Preparation of the P2 adapter for the MVME761 consists of installing a jumper on header J5 to enable the SCSI terminating resistors if necessary. Figure 1-17illustrates the location of the jumper header and connectors.
