The SCSI Interface
Chapter 3
In the simplest case, only two devices share the SCSI chain — the SCSI host and
the SCSI target device. In our case, the SCSI host is the Macintosh and the SCSI target
device is the scanner. This simple configuration is shown in Figure 3.10.

Connecting Two SCSI Devices
Figure 3.10
Two SCSI devices on the SCSI bus. (a) The Macintosh is the SCSI host, (b)
Coolscan is the SCSI target device. The rear view of your system may not be the same.
Procedure (Use the SCSI cable supplied with Coolscan):
1. Make sure that the Macintosh is powered off.
2. Connect the DB25-pin side of the cable to the Macintosh’s SCSI connector (on
the back of the Macintosh).
3. Connect the Centronics 50-pin side of the cable to the top SCSI connector on
the back of Coolscan. This cable will connect Coolscan to the Macintosh’s SCSI
bus.
4. Connect a SCSI terminator to the bottom SCSI connector on the back of
Coolscan, since this is the end of the SCSI chain. Termination on Macintosh Ilfic
systems requires the proper
black
terminator, supplied by Apple. Do
not
use the
gray terminator supplied with Coolscan.
In this case, both the SCSI host side of the bus and the SCSI target device side of
the bus must be terminated, as shown in Figure 3.10.
