SCSI
The SCSI port on the computer is a connector found
either inside the computer or on the rear panel of the
computer. There are three basic types of SCSI
connectors dealt with in this manuai.
The three types of SCSi connectors discussed in this
manual are the 50-pin internai connector, external 25-pin
DB25-type connector or 50-pin external Centronics
connector.

The External SCSI Connector
There are two typical SCSI connectors on computers.
The first is the 25-pin DB25 connector. This is the
standard connector used on the Macintosh computers. It
is a female connector, as shown in Figure 2.5 [a], and is
similar to the printer port connector. Do not confuse one
of the printer port connectors on the computer with the
SCSI connector should this type of connector be used.
The 50-pin Centronics connector is the most common
connector used for external SCSI connections on the
IBM-type PC computers. This connector is shown in
Figure 2.5 [b].
