User manual PLEXTOR ULTRA-B

[. . . ] ---- 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. If you own a PC, there are four ways in which you can make the SCSI connection: 1) Use a separate SCSI interface board. We recommend using a 32-bit PCI bus mastering SCSI interface board to maximize the drive's potential. [. . . ] Check the positioning of the rails by sliding the drive into the bay before you connect any cables. Check Your Jumper Settings Once you have determined a) the correct set of holes to use to attach mounting rails, or b) that you don't have to use mounting rails, you are almost ready to finish your drive's installation. If you do not have any SCSI peripherals (e. g. , hard disk, scanner, printer, etc. ) in your system other than your CD-ROM drive, you should not change the jumpers from their factory setting. If you do have other SCSI peripherals as part of your computer system, you may need to change the settings of the SCSI ID and Terminator. See Chapters 6 and 7 for information on how to change these settings. ULTRAPLEX OPERATION MANUAL 27 CHAPTER 8 ---- Hardware Installation 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 Audio Connector SCSI Interface Connector Jumpers Personal Computer Power Connector Power Supply from Personal Computer SCSI Ribbon Cable SCSI Host Adapter 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 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 UltraPleX CD-ROM drive, and any other SCSI peripherals. Additionally, ensure there are no kinks or knicks in the cable and that the length does not exceed 1. 5 meters. 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. DC Power Supply Pin 1 28 ULTRAPLEX OPERATION MANUAL CHAPTER 8 ---- Hardware Installation #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. If it does not, check for obstructions in the bay and ensure the side rails (if needed) are attached properly. You now need to make the power connection. In most computers you will find additional power connectors that are ready for use. Check the cable running from your power supply to your hard disk and see if it has extra connectors on it. [. . . ] Your SCSI interface board manufacturer will provide you with specific instructions. Adding CD-ROM Support After OS/2 Has Already Been Installed 1) You first need to verify that your SCSI interface board is supported by OS/2. Check your OS/2 manual, and the README file on the floppy disk that comes with the OS/2 CD-ROM, for information on which SCSI interface boards OS/2 supports. 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.
