SCSI cable
• The connector of SCSI cables or SCSI interface cards varies. A SCSI cable with proper
connectors for both the CRW-F1SX drive and the SCSI interface card is required.
SCSI connector of the CRW-F1SX drive is D-sub half-pitch 50-pin pin-type.

• For stable operation of SCSI devices, use short SCSI cables to connect them.
Connecting the devices with isometric cables is recommended.
• The maximum total length of the SCSI cables depends on the number of external
SCSI devices connected to the computer.
When one to three devices are connected, the total length of the SCSI cable must be
within three meters, and when four to seven devices are connected, it must be within
1.5 meters.
(An example of connection: connecting three external SCSI devices)
