Other necessary equipment
SCSI Device
SCSI devices which can send and receive data over SCSI and can set the ID number to "5"
can be connected the instrument. 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. Refer to section 16.7, for the SCSI specification.
Also, for information on general precautions in using the SCSI device, refer to the
instruction manual for that device.
SCSI cable
SCSI cables should have the connector shape and pin configuration which match the
"OPTION" connector on the rear panel of the DL1520L (refer to the figure above). They
should be less than 3 m long with a characteristic impedance between 90 and 132
Ω
. Also,
attach a ferrite core (TDK:ZCAT2035-0930A) on each end of the cable.
Terminator
Some SCSI devices require terminators. Follow the instruction manual for the SCSI device.
Note
DL1540/DL1540L with software (ROM) version 1.20 or later can save/load data from the SCSI device
through the SCSI interface unit 700930 (sold separately). For details, refer to the instruction manual for
the SCSI interface unit 700930, IM700930-01E.
