SCSI Termination

2-12
Serial Port 4 can be configured to use clock signals by the TRXC4
and RTXC4 signal lines. Header J15 configurations of the clock lines
are shown in Figure 2-10. The module is shipped without clock lines
connected (no jumpers).
Part of the configuration must be done with headers or switches on
the processor VMEmodule, as listed in Table 2-1.

You must ensure that the SCSI bus is terminated properly. The P2
adapter and the MVME712M module have sockets for terminating
the SCSI lines. Both the P2 adapter and the MVME712M use three
8-pin Single In-line Package (SIP) resistors. Refer to the installation
instructions in Installing the MVME712M, in this cahpter, for details
on use of the terminators.
