ULTRAPLEX 40X OPERATION MANUAL
connectors as you have internal SCSI peripherals (including one for
your Plextor CD-ROM drive), plus one additional connector to attach
to the interface board.
NOTE:
The UltraPleX Wide external drive uses high-density 68-pin
connectors — so called “wide” connectors.
If you have an external Plextor CD-ROM drive, you will be able to
include it in your daisy chain of other external SCSI peripherals with a
SCSI cable. Again, be sure you choose a cable with at least one 50-pin
high-density connector for an external drive or one 50-pin header type
connector for an internal drive. You’ll need a 68-pin high-density
connector for the UltraPleX Wide. Be sure to read the section on
“Termination” in Chapter 7.
If you purchased your SCSI interface board several months or years
before you purchased your UltraPleX drive, you may need to update
your device drivers. See the discussion about device drivers in
Chapter 9 of this manual.
NOTE:
When purchasing a SCSI cable, be certain that you are selecting a
quality cable and that it does not exceed the specified length for SCSI
cables. Poor quality external cables or overly lengthy cables may
result in poorer performance of your UltraPleX. The maximum cable
length should not exceed 1.5 meters.
3) You own a soundboard that has a SCSI interface built into it (e.g.,
Sound Blaster SCSI II).
We recommend against connecting your new UltraPleX 40max drive
to the SCSI interface of your sound card. These types of SCSI
implementations will limit the performance of this high-performance
drive. We do recommend using a separate SCSI interface.
Once you have assembled everything you need, you’re ready to install your
drive. But first, a few words of caution are in order.
If you are an Apple fan and purchased our Mac Kit, you will be lacking only
two items: an external SCSI cable and audio cables. Since we cannot predict
which Apple product you will use with your Plextor drive, we cannot predict
your cabling requirements — sorry. After you have identified the type of SCSI
connectors available on your Apple, contact one of the vendors listed in
Chapter 13 of this manual. Be certain to request shielded SCSI cabling. Our
UltraPleX 40max uses standard high-density 50-pin connectors, so-called
“narrow” connectors. The UltraPleX Wide external drive uses high-density 68-
pin connectors — so called “wide” connectors.
NOTE:
The iMac does not offer any SCSI connection at this time.
