8 Termination for Chains of SCSI Devices

Termination for Chains of SCSI Devices

What does termination mean?

Think of a pipe full of water. The pipe needs to have caps at both ends to prevent the water from spilling out. The termination on a SCSI device is analogous to the cap on the pipe. For a chain of SCSI devices to work properly the devices at the ends of a SCSI chain need to be terminated.

Devices that are not at the ends of the chain must not be terminated.

How do I terminate the CD-Writer Plus?

The CD-Writer Plus adjusts its termination automatically.

NOTE: If the CD-Writer Plus is the last of several devices in a chain, disable the termination on the device that was previously at the end of the chain. See the documentation provided with that device to see how to disable the termination.

The CD-Writer Plus installed at the end of a SCSI chain.

If you previously had only internal SCSI devices:

If you previously had only internal SCSI devices and the CD-Writer Plus is the first external device in the chain, you may have to remove or disable the termination on the SCSI card. While most newer SCSI cards adjust automatically, consult the documentation that came with your card to find out if you must disable the termination manually.
