Step 11 Connect SCSI I/O
SCSI Connectors
J15 (SCSI channel 1) and J16 (SCSI channel 2) are 68-pin high density (Wide) SCSI
connectors.
High Density SCSI Connectors
The 68-pin high density connectors are 0.050” pitch unshielded
connectors. The high-density connector pinouts are shown below:
These connectors provide all signals needed to connect to wide SCSI devices. The
connector pinouts are for a single-ended primary bus (P-CABLE) as specified in SCSI-3
Parallel Interface X3T9.2, Project 885-D, revision 1.2b, date July 2, 1993.
The cable assemblies that interface with this 68-pin connector are:
•
flat ribbon or twisted pair cable for connecting internal wide SCSI devices,
•
flat ribbon or twisted pair cable for connecting internal and external wide SCSI
devices,
•
cable assembly for converting from internal wide SCSI connectors to internal non-
wide (Type 2) connectors,
•
cable assembly for converting from internal wide to internal non-wide SCSI
connectors (Type 30), and
•
cable assembly for converting from internal wide to internal non-wide SCSI
connectors.
