If switch #4 is in the ON position, Coolscan is internally terminated. If switch #4
is in the OFF position (the factory default setting), Coolscan is «or internally terminat
ed. These two settings are shown in Figure 3.4 above.
SCSI Cables
There are three basic types of SCSI cables that can be used with Coolscan. These
are all 50 conductor cables, i.e. they have 50 contacts, or ‘pins.’ These three cables are
described below.
If you are installing an LS-10, please proceed to the section “SCSI Cables
Used With the LS-10.”
SCSI Cables Used With the LS-10E
Two different types of SCSI connectors exist on PC computers. The first is a 25-
pin DB25 type connector, and the second is a Centronics 50-pin type connector. The
SCSI cable provided with your Coolscan External model has one of each type connector
on opposite ends, as shown in Figure 3.5a. This cable is used for the default configura
tion of Coolscan, which is making the scanner the last device on the SCSI bus.

If you plan on placing Coolscan in the middle of the SCSI chain you will need a
Centronics 50-pin to Centronics 50-pin SCSI cable, as shown in Figure 3.5b. This
cable is not supplied with Coolscan.
SCSI cables should never be connected or disconnected while the SCSI device or
the computer is powered on. Such action can damage the SCSI controller card.
