Operating System:
5.0, 6.0
DOS
SCSI Adapter:
Adaptec AHA-1540B
Cables Required
The cable required will depend on the type of SCSI adapter installed on your com-
puter. For use with the Adaptec AHA-1540B, you will require a cable with a 50 pin
Centronics type connector on both ends. This may also be called a SCSI-1 cable.
It should be available from your hardware supplier or can be ordered from your
DAT-Link
supplier.
Installing an ASPI Driver
To use these tools, you must have a SCSI adapter installed which supports Adaptec's
ASPI
Advanced SCSI Programming Interface ( ). The software has been tested using
an Adaptec AHA-1540B SCSI Adapter. With this particular adapter, a device
ASPI
driver must be loaded to provide the interface. This is done by adding the
CONFIG.SYS
following line to the le, assuming that Adaptec's software was
C: ADAPTEC
installed in .
n
DEVICE=C:\ADAPTEC\ASPI4DOS.SYS /D
After adding the above command you will need to reboot your computer for the
driver to be loaded.
Choosing a SCSI ID
DAT-Link
Before connecting the , you need to check which SCSI ID's are already in
ASPI4DOS
use on your system. With the device driver loaded as described above,
a list of connected devices will be printed on the console during boot time. Note
DAT-Link
which SCSI ID's are in use and then choose an unused for the . Any ID's
DAT-
between 0 and 6 which do not show a connected device can be used for the
Link DAT-Link
. Note that although the 's ID switch goes up to 9, settings 8 and 9
are reserved for factory testing. ID 7 is usually reserved by the host computer. For
