Terminating the SCSI Bus 157

D24—Owner’s Manual
Terminating the SCSI Bus

Both ends of the SCSI bus must be terminated for correct operation. The D24 takes care

of termination at its end, so all you have to do is make sure that termination is applied

on the last device on the bus. Some SCSI disk drives feature automatic termination,

which automatically terminates the bus as necessary, while others feature termination

switches, which you must set manually. Some drives require you to plug a SCSI termi-

nator into the unused SCSI port. For information on setting SCSI termination on your

external disk drives, refer to the relevant owner’s manuals.

In the following example, two external SCSI disk drives are connected to the D24’s SCSI

port. Disk drive A is set to SCSI ID 0, disk drive B, to SCSI ID 1. Since it’s located at the

end of the SCSI bus, termination is applied on disk drive B.
