Cable Connections
You must make a minimum of two cable connections to your CD-ROM drive.
A third cable connection need be made only if you are using a soundboard in
your computer.
The two cable connections that you must make are:
1) SCSI cable
2) power cable
The SCSI cable you will need is determined by both the SCSI host adapter and
which device you have, the UltraPleX 40max or the UltraPleX Wide. The
UltraPleX 40max uses a standard 50-pin flat ribbon cable. The UltraPleX Wide
uses a 68-pin “wide” connector and ribbon cable. If you already have one
other SCSI peripheral (such as a hard disk) and your existing cable has only
two connectors, remove the cable and replace it with a cable with additional
connectors. Connect the SCSI host adapter to a connection on either end of
the cable. Connect the two peripherals to the other two connectors (one at the
middle connector and one at the end of the cable). Refer to Chapter 7 of this
manual for setting the termination of the devices.
CAUTION:
It is possible to accidentally plug your SCSI ribbon cable upside
down into both your drive and SCSI interface board. Accordingly,
be sure you match the red stripe along one side of the SCSI cable
to pin 1 on the interface board (if shown) and pin 1 on the drive
(as shown on the next page). Each connector on the 50-pin ribbon
cable has a “key” in the middle. This key should fit into a slot in
the middle of each connector of the interface board, your
UltraPleX CD-ROM drive, and any other SCSI peripherals. Each
connector on the 68-pin cable is shaped in such a way that it will
not allow an incorrect connection. Additionally, ensure there are
no kinks or nicks in the cable and that the length does not exceed
1.5 meters.
