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:
