4 - CONNECTIONS - DD1500X
DIP SWITCHES - SETTING SCSI ID AND TERMINATION
If you have just one DD1500x, you need not concern yourself with this too much as the
correct SCSI ID will have been set at the factory. The default settings for a single drive is
SCSI ID#0, termination ON and the rear panel DIP switches should look like this:
However, if you install another drive into the DD1500x, the DIP switches should be set
thus:
SCSI ID#0 is still selected for the first drive but its termination is now OFF. SCSI ID#1 has
been set for the second and it is terminated (you may, of course, set any SCSI ID you like
as long as it does not contend with any others on the buss).
The following table shows how to set the DIP switches on the DD1500x for SCSI IDs 0-7:
If you are using other drives in the system, then termination for the second disk in the
DD1500x should be switched off and the other drives terminated or otherwise as
appropriate.
If you are in any doubt about SCSI IDs and termination, please consult your dealer.
Similarly, if you are in any doubt about setting up a system with more than one drive,
please consult your dealer who will be able to advise you.
