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 VMEmodule.
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 1-16.1 illustrates the location of the
jumper header and connectors.
For further information on the preparation of the transition module
and the P2 adapter, refer to the userÕs manual for the MVME761
(listed in the Related Documentation appendix) as necessary.
