A-16 Scorpion 240 Autoloader Installation Manual
Connecting the SCSI interface cable
Turn off all power to your computer and drive. Then connect a
68-pin wide internal SCSI cable from your SCSI controller to
the SCSI connector on the back of the autoloader. Make sure
that pin 1 on the SCSI controller and cable is connected to pin
1 on the drive. Figure 4 shows the location of SCSI pin 1 on
the drive’s SCSI connector. Pin 1 on the SCSI cable should
be indicated by a colored stripe.
Scorpion 240 drives can be used with two different types of
SCSI interfaces: Ultra2 SCSI (LVD) or “Wide” (16-bit) single-
ended SCSI. The drive can automatically detect whether it is
connected to an LVD or single-ended wide SCSI bus.
Note: The Scorpion 240 will not operate properly in a SCSI-1
environment.

SCSI Termination
The internal Scorpion 240 does
not
provide SCSI termination.
For this reason, it should not be the last device on a SCSI
chain. Two termination examples are shown in Figure 5 on
the following page. If the drive is the only SCSI device, attach
the drive to the connector which is next to last on the SCSI
