Adapter-to-First Device Cables
Table 24 provides a list of adapter to first device cables.
Table 24. Differential-Ended Ultra SCSI Adapter-to-First Device Cables
Note: When cables are ordered by feature code, the appropriate terminator in
included with the order. When cables are ordered by part number, only the
cable is included. For terminator part numbers, refer to the Table 26 on page
116.
For this adapter, the same cable can be used for either single-ended or
differential attachments. The difference in feature code orders is the
terminator type.
The external connector on this adapter is the SCSI-III standard, 68-pin "P"
cable connector. Many of the 16-bit SCSI devices also use this connector
type, and, as a result, some cables can be used as either adapter-to-first
devices or device-to-device cables, depending upon what type of SCSI
connectors are present on the devices.
Device-to-Device Cables
Table 25 provides a list of device-to-device cables.
