Polaroid SprintScan 45 manual Power OFF on the SCANNER, the Computer

	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.
