SCSI Connectors

ADAC Ultra2 S466 provides several different types of

SCSI connectors. The connectors are:

∙one 68-pin high density internal connector, and

∙one 68-pin ultra high density external connector.

68-Pin High Density SCSI Internal Connector

The SCSI channel on the ADAC Ultra2 S466 Controller has a 68-pin high density 0.050 inch pitch unshielded connector.

This connector provides all signals needed to connect ADAC Ultra2 S466 to wide SCSI devices. The following connector pinouts are provided for both single-ended and differebtial primary bus (P-CABLE) as specified in SCSI-3 Parallel Interface X3T9.2, Project 885-D, revision 12b, date July 2, 1993.

The cable assemblies that interface with the 68-pin connector is:

∙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.
