I have an Adaptec 2940 card with the following internal drives -
Philips CDD2000 CD-R, CD-ROM drive, DAT drive and a Zip drive.
The card has an external 68-pin high density (SCSI-3) connector.

scanner has a 50-pin Centronics and a 25-pin female D-connector on the
I have purchased a 68-pin SCSI-3 to 50-pin Centronics cable. When I

this and have never used external SCSI devices before.
Is the cable the correct one ?

Do I need to terminate the internal drives as well as the external ?
Are there any settings or changes that I should look at in the card
setup (CTRL+A) ?
Thanks very much for any replies. I'm a complete newbie and
desperately want to get this scanner working !
Please also mail replies to me as well as the group.
