The SprintScan 45 scanner is unterminated. If it is the last
device in the chain, add a terminator. See the illustrations on
pages 2-9–2-10.
Powerbook note: According to Apple Computer, even
though this computer has an internal hard disk, you should
treat it as an unterminated device. This means that you must
have two terminators on the SCSI chain. Apple also advises
that if you have only one device connected to a Powerbook,
you must have two terminators on this one device. Refer to
the documentation included with your PowerBook.
Connection tips •WARNING: ALL CONNECTIONS MUST BE MADE WITH
THE POWER OFF ON THE SCANNER, THE COMPUTER,
AND ALL SCSI DEVICES.
•Always make SCSI connections firmly, connecting the clips or
tightening the screws that secure cables and terminators. Most
problems with SCSI devices are connection problems along
the SCSI chain.
•The SprintScan 45 scanner has two SCSI connectors; one has
50 pins and one has 25. A SCSI cable can be connected to
either port without affecting the performance of your equip-
ment.
•Each device on a SCSI chain must have a unique SCSI ID
number. These numbers are described in the following
section.
•If a 50-to-50 pin cable is required, be sure to use a cable
which meets the SCSI-2 specification, such as an Apple cable.
