PC Installation Guide
The instructions in this section show how to install the SCSI model of
the Zip
®
250 drive on PCs that are using Windows NT, 95/98 or 3.1.
Check your SCSI connection.
Your Zip drive meets SCSI-1 specifications and is designed to connect
to a standard 25 pin SCSI connection (illustrated below).
Standard SCSI-I Connector
(25 Pin D-Sub)
CAUTION Iomega internal testing indicates that the Zip drive works
when connected to the end of a Fast SCSI-2 or Ultra SCSI chain using a
high quality cable. However, the drive does not meet SCSI-2 or Ultra
SCSI specifications and may not work correctly in these configurations.
Data integrity could possibly be affected. M
If you choose to connect to a Fast SCSI-2 or Ultra SCSI chain, make
sure the Zip drive is always connected at the end of the chain. The Zip
drive does not operate at Fast SCSI or Ultra SCSI speeds but should
not slow the performance of other devices if it is connected at the end
of the chain.
M 50 Pin SCSI Connection: See Cables and Converters ... on page
15 for information on the cable or converter you will need to use. M
For best results with your Zip drive, connect to an Iomega Zip
®
Zoom
™
SCSI card. Make sure the adapter card is installed in the
computer before attempting to connect your Zip drive.

If you plan to use a non-Iomega SCSI adapter, refer to the Iomega
web site (www.iomega.com) for information on compatible adapters.
Install the driver software (Windows 95/98 mini-port driver or ASPI
manager) for the adapter before installing your Zip drive.
