---- CHAPTER 1 ---- Introduction Thank you for purchasing a Plextor 12/20PleX, a 12/20 speed CAV CD-ROM drive meant for the professional and power user. The 12/20PleX is the most reliable and highest performance CAV CD-ROM drive available in its class. The 12/20PleX is also the first CAV CD-ROM drive manufactured by Plextor.

CHAPTER 1 ---- Introduction the innards of their computers. Plus, our Technical Support Department is just a phone call or e-mail message away. In this manual you should find all the information you need to successfully install and operate your drive. If you run into a problem, however, please contact us (see Chapter 13 for the different ways you can contact us).
Compare what you find in the box with the tables on the following pages. What you should find in your Plextor box depends on two factors: 1) what configu- ration you purchased; and 2) what the company that sold you the box put in----or took out----while it was in their possession.
Use the following tables to check the contents of your box: 12/20PleX Internal Drives CD-ROM drive Side rails with 4 chrome and 4 black screws Plextor Manager floppy disk SCSI interface board & installation guide Audio cable SCSI cable Plextor operation manual...
Therefore, please ship your drive in the safest manner possible. We believe your drive will be most secure if it is shipped in a Plextor box. We hope you will never have to ship your drive back to us. If you do, however, please send it packaged in a Plextor box.
Inventory your current computer system; check list below. If you are a PC owner and you purchased a Plextor box labeled ‘‘Drive with SCSI Interface Kit,’’ your needs are simple: none. The same holds true if you are a Mac owner and purchased a Plextor box labeled ‘‘Drive with Mac Kit.’’...

CHAPTER 3 ---- What Else Do I Need? If you purchased your SCSI interface board several months or years before you purchased your 12/20PleX drive, you may need to update your device drivers. See the discussion about device drivers in Chapter 9 of this manual. 3) You own a soundboard that has a SCSI interface built into it (e.g., Sound Blaster SCSI II).
Please read this manual carefully and keep it handy for easy reference. Use this manual for installation, operation, and troubleshooting. See your dealer, or call Plextor’s Technical Support Department, should your drive require repair or service. Do not put your computer monitor (or any other device weighing more than 30 lbs.) on top of the 12/20PleX external drive.
---- CHAPTER 5 ---- Drive Features YOUR TASK: Get to know your drive. YOUR OBJECTIVE: Learn how to operate different features of the drive. Learn what goes where. Learn some terms that will be used elsewhere in the manual. YOUR METHOD: Match the parts of your drive to the diagrams below.
Audio CD Play Button: Push to put drive in Audio CD play mode. Push button once during CD play mode to skip. Push and hold down play button more than one second to fast forward. ON/BUSY Indicator: Yellow when power is turned on. Flashing when disc is inserted and being accessed.

You should leave the jumpers found on the rear panel of the PX-20TSi and the switches and rotary dial found on the rear panel of the PX-20TSe at their factory settings unless: 1) you plan to use another SCSI peripheral (e.g., hard disk, scanner) attached to the same SCSI adapter, in addition to your CD-ROM drive;...
If the CD-ROM drive is the only SCSI peripheral you will use with your computer, you do not need to boot from the CD-ROM drive in a UNIX environment, and if you do not plan to use the Eject Lock feature, skip now to Chapter 8, Hardware Installation. (Take our word for it, most of you can now skip to Chapter 8.) PX-20TSi Internal Drive Factory Setting of Jumper Block...
SCSI peripherals, however, it is necessary to set each peripheral to a unique SCSI ID number. Your Plextor CD-ROM drive can be set to use one of eight SCSI ID numbers. The drive should arrive with its SCSI ID set to 3. Accordingly, if you already use another SCSI peripheral, and its SCSI ID also is set to 3, you must change the SCSI ID number of either this peripheral or that of the CD-ROM drive.
Turn the drive’s power OFF before changing the setting of the dial or DIP switches. The SCSI ID number of the PX-20TSe is determined by the position of the pointer on the SCSI ID rotary dial. The drive should arrive with its SCSI ID set to 3.
CHAPTER 6 ---- Drive Switch/Jumper/Dial Settings Other Switch/Jumper Settings----12/20PleX The remaining switches (external drives) and jumpers (internal drives) are: Parity Leave this ON. The parity check provided by the ON setting enhances the reliability of the SCSI bus. Set to OFF only if your computer system or SCSI controller specifically requests that parity be disabled.
. This should not be confused with termination itself. power can and should be provided by at least one device Termination attached to your SCSI host adapter. Your Plextor CD-ROM drive auto- matically supplies termination power. Any additional devices supplying termination power will NOT cause any problems.
ON. PX-20TSe External Termination The PX-20TSe is shipped from the factory with its termination turned ON. To turn the termination OFF, first turn off the drive’s power, then change the second DIP switch on the rear panel of the drive to the OFF position. Refer to the pictures on pages 13 and 17 for the location of the termination switch (labeled ‘‘Term’’).
