MVME712B Module Preparation, Scsi Termination | Motorola MVME712-13

Hardware Preparation and Installation

SCSI Termination

2

Because the MVME712x has no provision for SCSI connection, you must ensure that the SCSI bus is terminated properly. The LCP2 adapter has sockets (R1, R2, R3) for terminating the SCSI lines using three 8-pin SIP resistors. Refer to the Installation Instructions for use of the terminators.

MVME712B Module Preparation

No preparation of the MVME712B is necessary. The location of the connectors is illustrated in Figure 2-5.
