User manual PLEXTOR 12-20B

[. . . ] ---- CHAPTER 8 ---- Hardware Installation By itself, your CD-ROM drive is incapable of communicating with your computer. You must use a hardware link that enables your drive to ``talk'' with the rest of your computer. Plextor's 12/20PleX drives use a SCSI interface as their link. If you own a PC, there are four ways in which you can make the SCSI connection: 1) Use a separate SCSI interface board. [. . . ] If you are connecting the host adapter to your Plextor drive only, use the two end connectors and ignore the one in the middle. 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 the cable provided by Plextor. 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. If you have more than one other internal SCSI peripheral (besides your Plextor drive), you will need to acquire a SCSI ribbon cable with more connectors (one connector for each internal SCSI device, plus an additional connector for the host adapter----refer to Chapter 3). 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 and pin 1 on the drive (as shown on the next page). 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 12/20PleX CD-ROM drive, and any other SCSI peripherals. DC Power Supply Pin 1 28 12/20PLEX OPERATION MANUAL CHAPTER 8 ---- Hardware Installation 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. #1 To Pin #1 Either end of the cable may be connected to either the CD-ROM drive or to the SCSI interface board Pin #1 The easiest way to install your SCSI cable is to plug it into the SCSI connector on the rear panel of the drive before you insert the drive into your computer. Then you can thread the cable through the front of the open bay you plan to use and back toward the SCSI interface board. Connect the cable to your SCSI interface board and finish mounting your drive in the proper position. The drive should slide smoothly into the bay. Follow directions below for making cable connections. Review your current computer setup to see if the potential for conflicts exists. If so, make necessary switch, dial, and/or terminator changes. YOUR OBJECTIVE: YOUR METHOD: If you are installing a single 12/20PleX external drive, and you have no other SCSI peripherals attached to your system, you should leave the switches, dial, and terminator found on the rear panel of your drive at their factory settings. If you do have additional SCSI peripherals (e. g. , scanner, printer) attached to your computer, you may need to change your switch, dial, and terminator settings. See Chapters 6 and 7 for information on how to change these settings. If you are installing a single 12/20PleX external drive, connect it as shown on the next page: 30 12/20PLEX OPERATION MANUAL CHAPTER 8 ---- Hardware Installation PC Connection SCSI Interface Board SCSI Cable Secure to controller by pushing gently until cable ``snaps'' into place.

[. . . ] If your SCSI interface board is included on the list of supported hardware, you can skip to step #3. 2) If your SCSI interface board is not on OS/2's list of supported hardware, you must contact the manufacturer of your board and request an OS/2 software device driver. (See listing of contact phone/fax/BBS numbers on page 61. ) 3) Once you have confirmed that your SCSI interface board is supported by OS/2, or you have obtained the necessary device driver files, run OS/2's Selective Install program to set up your SCSI interface board and CD-ROM drive. In the ``SCSI Host'' field, select your board. [. . . ]
