Previous last SCSI device may need to be “un-terminated”. Find this flat cable! SCSI Cable 68 Pin*/ 50 Pin Width *Adapter required (not included) c IDE Cable 40 Pin Width 34 Pin Width Floppy Disk Drive Cable l If CD-RW drive is not on end of SCSI cable or last physical device, remove the “ Active Term” jumper and assure the last physical SCSI device is properly terminated or activated. Note: Note: Only the last physical SCSI device needs to be terminated. There may already be internal or external SCSI devices (HDD, Scanner, CD-ROM) connected to the SCSI cable. If so, determine the SCSI ID# of each SCSI device. This information is required for Step 5 “Setting the Jumpers. ” Refer to SCSI device(s) for ID data. In some cases, a SCSI chip set may be implemented on the motherboard. 8 Hardware Installation Hardware Installation 9 Step 5: Setting Set jumpers on rear of drive unit according to your computer Jumpers are factory preset as shown below. ID 1 TEST ACTIVE TERM ID 2 ID 4 The following table shows the function of each jumper. Jumper ACTIVE TERM ID SELECT ID number 0 1 2 3 4 5 6 Jumper settings OFF ON OFF ON OFF ON OFF OFF OFF ON ON OFF OFF ON OFF OFF OFF OFF ON ON ON TEST ON: Enables test mode OFF: Enables normal operation Function ON: Enables active termination OFF: Disables active termination Assign the drive unit’s ID number by setting these jumpers to ON or OFF. Do not assign the same number as one used for other SCSI device. Factory settings ID 1 TEST ACTIVE TERM ID 2 ID 4 Notes: . The upper row of pins is (without position KEY) is ground. . Remove jumper to set OFF, install jumper to set ON. . ID SELECT, ACTIVE TERM, and TEST MODE are recognized when the power supply is turned on or the SCSI bus is reset. . TEST mode is used exclusively for factory testing. Do not set TEST mode to ON. Doing so may cause unexpected (disastrous) results. 10 Hardware Installation Hardware Installation 11 Step 7: Mounting the Drive Insert the CD-RW drive into computer front as shown, routing cables accordingly. Secure drive to frame with appropriate screws. Note: Slide rails (not included) may be necessary if you cannot secure CD-RW drive. Refer to your computer’s User’s Guide for more information. Step 8: Connecting the Power Cable Locate an available power supply cable, within computer, and connect it to the rear of CD-RW drive as shown. Note: The power supply cable connector is designed to fit one way, do not force it upside down, this could damage drive and void the warranty. DC INPUT GND 12V 10% 5V 5%+- +- Step 6: Connecting the Drive Attach flat SCSI cable to connector at rear of CD-RW drive. Notes: The 50 pin flat SCSI cable must be firmly attached with its red edge (Pin 1) positioned next to the power supply connector. If computer has a Sound Card, an Audio Cable may be connected to the rear of the CD-RW drive. Contact a local dealer if cable is required. Interface Connector Pin 1 Power Supply Connector Red Edge Audio Cable Audio Out Connector SCSI Flat Cable CD-R/W Drive Unit Mounting Screws Audio Cable Flat Cable 12 Hardware Installation Hardware Installation 13 Power Supply Connector Power Supply Cable Software Please refer to CD-RW formatting software/CD manual for instruction Step 9: Installation software installation. CD-RW formatting software must first be properly Now let us review the hardware installation process, assuring that: installed in order to write CD’s with this device. l All connectors are properly connected. l Each SCSI device has its own unique SCSI ID number. l The last physical SCSI device on the bus is properly terminated. 1 49 50 Red Edge Notes l Red edge of 50 pin flat SCSI cable must be on pin 1 of host adapter. l The following is a sample configuration of CD-RW installation. 0 1 2 AUDIO OUT R GND L DC INPUT 5V ± 5% GND 12V ± 10% ACTIVE TERM TEST ID SELECT 1 2 49 50 CD-R/W Drive Power Supply Cable Red Edge SCSI Card (Not included) Speakers (Not included) Sound Card (Not included) Audio Cable (included) SCSI Cable (Not included) Step 10: Closing the Computer Carefully replace computer cover, per Owner’s Manual. Hardware installation is now complete! 14 Hardware Installation Using Discs Storing Discs . Do not store the disc in a location subject to: – high humidity – high temperature – excessive dust – direct sunlight Care of Discs . Only hold disc by its edge. Do not touch the record surface. . Do not wipe CD-R/RW discs before recording data. To avoid scratching the recording surface, blow away dust using an air blower. Software Installation/Using Discs 15 Operating Assure application software using the CD-RW drive. As the drive begins reading the Table of Contents (TOC) data, the busy indicator lights and remains illuminated until read is completed. When the busy indicator switches off, the drive is ready to receive Starting Up commands, data may be retrieved from the disc. After loading a disc, it takes a moment for the drive to become ready while Program Memory 1 Turn on the compute...
