Cable Connections
You must make a minimum of two cable connections to your internal CD-R 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 a standard 50-pin flat-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 easy 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 (as shown on the next page) and Pin 1 on the drive. Each connector
on the 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
PlexWriter, and any other internal SCSI peripherals.
Double-check your work; you must ensure the side of the SCSI cable with
the red stripe is matched to Pin 1 on the interface board and on the drive.
