SCSI Devices that can be Used* HD Drives : SCSI HD drives for MS-DOS ver.3.3 or later, or SCSI HD drives that can format in
EZ-SCSI.
MO Drives : 128/230/640 MB drives. MO media uses Semi IBM format.
ZIP Drives
PD Drives
* SCSI devices which can send and receive data over SCSI and which can set the ID number to "5" can be used. There are exceptions as
in the case when the media used on the SCSI device is formatted with another equipment such as a PC, or the pin configuration of the
connector is different. The specifications of each SCSI device are shown above. For more detailed information, contact your nearest
YOKOGAWA representative listed on the back cover of this manual.
