All SCSI devices attached to your computer are assigned a SCSI-ID number from 0 to 7. Your CD-ROM’s SCSI ID must be set so that its ID number does not conflict with any other device’s SCSI-ID in your system. In most cases your CD-ROM will come set to SCSI ID 0. If your CD-ROM is the only SCSI device connected to your computer, you should leave the jumpers as they are. If you have additional SCSI devices (another CD-ROM, hard drive, etc.) you will be “daisy-chain- ing” these devices. Each SCSI device must have a different SCSI ID. Note that your SCSI interface card in most cases has a SCSI ID of 7. The chart below shows the jumper settings for the eight possible ID numbers:
ID1 ID2 ID4 ID1 ID2 ID4 ID1 ID2 ID4 ID1 ID2 ID4

Parity Jumper
The Parity Jumper should be set to OFF (no jumper present). This jumper activates/de-activates the parity bit check function on the SCSI data bus. This enhances data bus reliability. (Cannot be used if no parity generation function is provided on the I/F card.)
