[. . . ] A standard caddy is made of plastic and has a metal shutter on its bottom which slides open and shut. Plextor is also constantly evaluating other caddy designs for possible use in the future. Unless provided or recommended by Plextor, use of a non-standard caddy (e. g. , one that lacks a metal shutter on its bottom) is not recommended. For their protection, CD-ROM discs should be stored in their original packaging or in a caddy. Inserting the Disc into a Caddy 1) To open the lid of the caddy, press the tabs at the side as shown. 40 ULTRAPLEX OPERATION MANUAL CHAPTER 10 ---- Using CD-ROM Discs, Caddies, and Trays 2) Place the disc into the caddy with the label facing UP.

ULTRAPLEX OPERATION MANUAL 47 CHAPTER 12 ---- Troubleshooting 12. 1 PC Compatibles: Initial Installation Symptoms · No sound when running a CD-ROM program Additional Symptom No sound when playing an audio CD Possible Causes and Solutions Application Does Not Use CD-Audio There are two types of audio you may encounter when using CD-ROMs: 1) Sound Card Audio: This comes from data (e. g. , . WAV or . MID files) that is transferred from your CD-ROM disc via the SCSI host adapter into your computer and is translated by your soundboard into sound. If you do not have a soundboard, you will not be able to hear this form of audio. 2) CD Audio: This comes from audio discs (like the ones used by your home stereo) that are translated directly by your CD-ROM drive into sound. You can hear this audio by plugging a set of headphones or powered speakers into the headphone jack on the front of your drive. One reason, then, that you might not hear sound when playing a CD-ROM disc is that a soundboard is required. To help you determine if you are having a soundboard problem, or a CD Audio problem, try playing an audio CD in your CD-ROM drive. If you can hear music (through headphones or speakers connected to the headphone jack on the front of your drive), the CD-ROM disc you are playing may require the use of a soundboard in order to hear sound. If possible, check the manual that came with the CD-ROM disc and see if the use of a soundboard is recommended or required. If you have a soundboard and can hear an audio CD when it is played but cannot hear sound when you play a CD-ROM disc, you may have configured your soundboard incorrectly. Conflict Between MS-DOS 6. 0 and Microsoft's CD-ROM Extensions (file name: MSCDEX. EXE) Version 2. 21 (or Lower) MSCDEX. EXE ver. Use of an earlier version will result in an INCORRECT DOS VERSION message. 2. 21 (or lower), your computer might still be recognizing this lower version rather than 2. 22 (or higher). To correct this problem, you must edit your AUTOEXEC. BAT file using a text editor or word processor. Your AUTOEXEC. BAT file will probably contain a line that looks something like this: C:\TSCSI\MSCDEX. EXE /D:TSLCD /M:10 In this example, ``C:\TSCI'' is the path to MSCDEX. EXE. The path name will vary depending on the type of SCSI device driver software you use. Change only the path of this line in your AUTOEXEC. BAT file so that it finds the updated MSCDEX. EXE file in your DOS directory. This line should be edited to read: C:\DOS\MSCDEX. EXE /D:TSLCD /M:10 Save the AUTOEXEC. BAT file and reboot your computer. 52 ULTRAPLEX OPERATION MANUAL CHAPTER 12 ---- Troubleshooting Symptoms · No Device Found · No SCSI Interface Board Found or No Response from SCSI Interface Board Additional Symptom Driver Fails to Recognize the SCSI Interface Board Possible Cause and Solution Drive Not Resetting In some cases, even if you restart the computer by pressing its reset button or the Control, Alt, and Delete keys simultaneously, the drive does not appear to respond. Try turning the power switches on the drive and computer OFF, then ON. This complete shutdown should fully reset the drive and computer.

ULTRAPLEX OPERATION MANUAL 55 CHAPTER 12 ---- Troubleshooting Drive Not Terminated If your CD-ROM drive is the only SCSI peripheral attached to your computer or is the last SCSI peripheral in a daisy chain (i. e. , a cable connecting multiple SCSI peripherals to a single SCSI interface board), check that its termination switch is ON. Always turn the drive OFF before changing the setting of the rear-panel switches. See Chapter 7. Symptom · CDR101----Not Ready Reading Drive [X] Additional Symptom All Commands Sent to the Drive Result in CDR101 Error Possible Causes and Solutions Audio CD Disc in the Drive Plextor CD-ROM drives are capable of playing high-quality audio when used with appropriate audio playback software or when the drive is set to Audio CD play mode (see Chapter 11). Since audio compact discs do not have computer data, typing standard data commands when an audio CD is in the drive will result in an error message. [. . . ]
