Scsi Connectors J5 And J7; Scsi Connectors J5 And J7 Interconnect Signals - Motorola MVME712-10 User Manual

SCSI Connectors J5 and J7

Connectors J5 and J7 are identical; two connectors are provided for
convenience of access. They convert low-density 8-bit-wide SCSI connectors to
the high-density 16-bit-wide connector J6 (theP cable connector). Each pin
connection, signal mnemonic, and signal characteristic for the connectors is
listed in Table 3-2. Refer also to the schematic diagram for SCSI interconnect
lines.
