The SCSI Interface
Make sure not to confuse the printer port connectors on the computer with the
25-pin DB25 SCSI connector, should this type of connector be used.

Typical SCSI connectors on the rear of the computer, (a) DB25 connector.
(b) 50-pin Centronics connector.
The second type of SCSI connector found on PCs is the 50-pin Centronics con
nector, which is commonly used for external SCSI connections. This connector is
shown in Figure 3.7b. If your PC already has installed a SCSI controller card with a 50-
pin Centronics external connector, you will not be able to use the SCSI cable provided
with Coolscan. Instead, you will need a 50-pin Centronics to 50-pin Centronics SCSI
cable.
Please proceed to the section “The SCSI Chain.”
The PC's Internal SCSI Connector
The SCSI connector for internal SCSI devices on the PC is a 50-pin flat connec
tor residing on the SCSI controller card. Please note that Coolscan will not operate
properly unless it is connected to the SCSI controller card. Do not connect Coolscan to
any SCSI accelerator card that may be installed.
Connecting to the Internal SCSI Connector
Again, the SCSI connector on the PC’s SCSI controller card is a 50-pin flat con
nector as shown in Figure 3.8. Note the position of pin 1 and the safety key. The safety
key provides a level of protection against inserting the improperly.
