SCSI Device Configuration Menu

4 Technical Information

Configuring a SCSI Accessory

This menu lets you configure parameters for each SCSI device on the SCSI bus. To configure a specific SCSI device, you need to know which SCSI ID it uses. To know the SCSI ID of a specific SCSI device, you can run the SCSI Disk Utilities (refer to page 112).

•Initiate Sync Negotiation

Some older SCSI-1 devices do not support synchronous negotiation. Set Initiate Sync Negotiation to No for these devices.

•Maximum Sync Transfer Rate

If the SCSI device is an UltraWide SCSI device, you can use the maximum value of 40.0 MB per second. For Ultra narrow SCSI or Wide SCSI devices you can select a maximum transfer rate of 20.0 MB per second.

Certain older SCSI-1 devices do not support UltraWide SCSI (up to 40 MB per second) or Ultra narrow SCSI or Wide SCSI data transfer rates (up to 20 MB per second). Select a Maximum Sync Transfer Rate of 10.0 MB per second for these devices.

•Enable Disconnection

To optimize SCSI bus performance, Enable Disconnection should be set to Yes.
