2.4 Machine Sp ecic Instructions 29
The above assumes that the DAT-Link resides at SCSI ID 5, on SCSI bus 0. If
another ID was used, replaced the '5' in 'tps0d5nr' above with the appropriate
numb er. If a dierent bus is used, replace the '0' ab ove by the appropriate bus
numb er.

Op erating System: DOS 5.0

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 typeconnector on b oth ends. This may also b e 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 to ols, you must have a SCSI adapter installed which supports Adaptec's
Advanced SCSI Programming Interface ( ASPI ). The software has b een tested using
an Adaptec AHA-1540B SCSI Adapter. With this particular adapter, a device
driver must be loaded to provide the ASPI interface. This is done by adding the
following line to the CONFIG.SYS le, assuming that Adaptec's software was
installed in C: n ADAPTEC .
DEVICE=C:\ADAPTEC\ASPI4DOS.SYS /D
After adding the ab ove command you will need to reboot your computer for the
driver to b e loaded.
Cho osing a SCSI ID
Before connecting the DAT-Link ,you need to check which SCSI ID's are already in
use on your system. With the ASPI4DOS device driver loaded as describ ed ab ove,
a list of connected devices will be printed on the console during bo ot time. Note
which SCSI ID's are in use and then cho ose an unused for the DAT-Link . Any ID's
between 0 and 6 which do not show a connected device can b e used for the DAT-
Link . Note that although the DAT-Link 's ID switch go es up to 9, settings 8 and 9
are reserved for factory testing. ID 7 is usually reserved by the host computer. For
