Changing the SCSI ID
If you already have another SCSI peripheral whose SCSI ID is set to 4, you must
change the SCSI ID number of either that peripheral or that of the PlexWriter drive.
(But see “Do I Have to Change My PlexWriter's SCSI ID number?” on page 12
before proceeding.)
To change the SCSI ID number of the external PlexWriter drive, rotate the dial’s
arrow to a different SCSI ID number.
Changing the SCSI Termination Setting
The PlexWriter external drive is shipped from the factory with its SCSI termination
enabled (ON). If you have to disable SCSI termination on your PlexWriter drive, set
DIP switch 2 to OFF.
If you are using external SCSI peripherals only, then you should be using an external
SCSI cable (or cables). In this case, all devices between the SCSI host adapter and
the last peripheral on the end of your SCSI chain, should have their termination
removed, disabled, or turned off.
If you have both internal and external SCSI peripherals (both the internal and
external connectors of your host adapter are used), then the termination of your SCSI
host adapter should be removed, disabled or turned OFF. The
last
peripheral on your
internal cable and the
last
peripheral on your external SCSI chain should retain their
termination (have it set ON). All other SCSI peripherals connected to the host
adapter should have their termination removed, disabled, or turned off.
NOTE: The SCSI interface board that is bundled in the Plextor kits has Auto
Termination, so turning off its termination is unnecessary. However, you still must
sometimes specify termination ON or OFF on the PlexWriter drive.
Install a SCSI Interface Board
By itself, your PlexWriter is incapable of communicating with your computer. You
must use a hardware link that enables your drive to “talk” with the rest of your
computer. The PlexWriter uses a SCSI interface as its link.
SCSI board already installed?
Even if you already have a SCSI board in your
computer, it may not be adequate for use with your high-performance PlexWriter
drive. See “How to Choose a SCSI Board” for more details. Then, if your SCSI
board is suitable, you can go directly to “Install an Internal PlexWriter Drive” on
page 22; or to “Install an External PlexWriter Drive” on page 28.
