Chapter 3 The SCSI lnterfa<e
SCSI termination remains more of an art than a science. You may find that your
computer will not recognize all of the SCSI devices installed when you restart your sys­
tem after connecting Coolscan. You may need to deal with a number of special case sit­
uations. For example, the Macintosh Quadra requires specific installation procedures
not applicable to other Macintosh systems. The Macintosh Ilfx is another special case.
The Ilfx should only be terminated using the
black
terminator that is supplied with the
system. Using the
gray
terminator, which is supplied with Coolscan, may cause damage
to the computer. If you don’t have the special black terminator, contact your autho­
rized Apple dealer to obtain one.

If you are installing an LS-10, please proceed to the section “Terminating the

Terminating the LS-10E
The LS-lOE is configured with two 50-pin SCSI connectors on the rear of the
unit, as shown in Figure 3.3. Install the standard 50-pin SCSI terminator (remember,
you need the special black terminator for a Ilfx) onto the bottom connector if termina­
tion is desired. If you would like Coolscan to reside in the center of the SCSI chain,
then by necessity, the bottom connector will be used for a SCSI to SCSI jumper cable.

Termination Power
Unlike other Macintosh computers, the PowerBook does «or supply SCSI termi­
nation power. To use the LS-lOE with a PowerBook, the SCSI Termination Power
Switch, labeled “TERM PWR” on the rear of the unit (see Figure 2.2) must set to the
ON position. This configuration will require termination at both ends of the SCSI
chain. For further information, refer to the Macintosh User’s Guide for Macintosh
PowerBook Computers.
