Understanding SCSI

Connector Types

Several different types of SCSI connectors are used on SCSI devices,

and each type requires a different kind of cable. The following dia-

grams illustrate the different kinds of SCSI connectors:

If you have a SCSI device with a DB25 connector, you can order a

free DB25 cable from Adaptec to connect it to the SlimSCSI 1460. The

mail-in card for the cable is inserted in this User’s Guide.

The total length of cabling on the SCSI bus should not exceed the

maximum lengths listed in the following table:

Maximum Cable Lengths
