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
SL1400.
2.
Turn ON the SCSI device and the SL1400 (in that order).
To format the disk, follow the procedure described in the section 13.6.
Connectable SCSI Devices
SCSI devices that can be connected to the SL1400 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 SL1400 fails to detect the external SCSI device that is connected, initialize the SCSI
ID by press the MENU key > Next 1/2 > Self Test > Test Item to SCSI > Initialize SCSI.
•
The SL1400 has a built-in SCSI terminator. When using multiple SCSI devices, connect
the SL1400 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 by pressing the
MENU key > Next 1/2 > Self Test > Test Item (SCSI) > Internal ID.
