Connecting SCSI devices

A SCSI device is any product—including hard disk drives, CD-ROM drives, scanners, and printers—that connects with your computer by means of a standard electronic interface called Small Computer System Interface (SCSI).

You can attach up to 6 SCSI devices to your computer by linking them together in a chain that starts at your dock’s SCSI port. There is a SCSI port on the PowerBook Duo Dock and the PowerBook Duo MiniDock. (There is no SCSI port on PowerBook 200 Series computers.)

To connect a SCSI device to your PowerBook, you need an Apple HDI-30 SCSI System Cable or equivalent. This cable is light gray (the same color as desktop Macintosh computers), is about 19 inches long, and has 29 pins (one “missing pin”).

Refer to the manuals that came with your SCSI devices for instructions on installing any necessary software, setting SCSI ID numbers, and connecting SCSI cables and SCSI terminators. Refer to the illustrations below for the proper positioning of SCSI terminators.

WARNING When connecting SCSI equipment, always turn off power to all devices in the chain, including your computer. If you don’t, you could lose information and damage your equipment.

Where to add cable terminators when connecting a single SCSI device:
