Chapter 3 The SCSI Interface
Centronics 50-pin female connector, similar to what is found on the rear of Coolscan.
The SCSI cable provided with your LS-lOE has a DB-25 connector on one end, and a
Centronics 50-pin connector on the opposite end, as shown in Figure 3.5a.
This cable is
used for the default configuration of Coolscan, which is making the scanner the first device on
the SCSI bus.
Figure 3.5 SCSI external cables, a) The 25-pin DB-25 to Centronics 50-pin cable.
(b) The Centronics 50-pin to Centronics 50-pin cable.
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 «or supplied with Coolscan.
SCSI cables should never be connected or disconnected while the computer’s or
SCSI device’s power is on. Such action can damage the SCSI controller chip on
your Macintosh, requiring a motherboard replacement.
Please proceed to the section “The Macintosh’s External SCSI Connector.”
SCSI Cables Used With the IS-10
The SCSI cable provided with the LS-10 enables you to connect the scanner to
the Macintosh’s SCSI chain as either the only device on the SCSI bus, or as an addition­
al device. This is a
chainable SCSI flat cable Wit\\
two identical crimped connectors on
each end and one connector crimped in the center, as seen in Figure 3.6a.
If Coolscan is to be the only internal SCSI device: Connect one end of this
cable to the existing SCSI bus in the Macintosh (connecting the SCSI cable to the
Macintosh’s SCSI bus will be explained in the next section), then connect the opposite
end to the SCSI connector on the rear of Coolscan (refer to Figure 2.3 to locate the
SCSI connector). The center connector is «oiused. Make sure that DIP switch # 4 is
in the termination ON position, as indicated in Figure 3.4.
