Items Necessary for Connection
Cable
Use a commercially sold cable that is 3 m or less in length that has a characteristic
impedance between 90 and 132 Ω.
Connection Procedure
1. Connect the SCSI cable to the SCSI connector on the left side panel of the
DL750/DL750P.
2. Turn ON the SCSI device and the DL750/DL750P (in that order).
To format the disk, follow the procedure described in the section 13.5,
“Formatting the Storage Medium.”
Connectable SCSI Devices
SCSI devices that can be connected to the DL750/DL750P are MO disk drives and Zip
drives.
For details on which devices can be connected, contact your nearest YOKOGAWA
dealer.
For general handling precautions for the connected SCSI device, see the instruction
manual that is provided with the device.
Note
• If the external SCSI device that is connected cannot be detected on the DL750/DL750P,
execute the initialization of the SCSI ID using SCSI ID > Initialize SCSI on the MISC
menu.
• The DL750/DL750P has a built-in SCSI terminator. When using multiple SCSI devices,
connect the DL750/DL750P to the end of the chain. The terminator is always ON when
the power is ON.
• Do not connect an external SCSI device with the same ID as that specified using SCSI ID
> Internal ID on the MISC menu.
