<P>I don`t think that it is a problem of the scanner. It is a known problem caused by

termination, cable or scsi-driver problems.

|

|
|
<P>The scanner does not do any termination. You mean the termination that came with
|
|
<BR>
|
|
the scanner? That is a passive one. If you work with a fast scsi card that should be ok,
|
|
<BR>
|
|
for an ultra scsi card you should use an active one.

<BR>
|
|
<P><EM>> c) Do I need to terminate the "internal" 50-pin connector on the

</EM><BR>
|

<EM>> SCSI card if I don't have a hard disk or CD-ROM drive on it? How would I
|
|
</EM><BR>
|
|
<EM>> do that?
|
|
</EM><BR>
|
|
<P>YES, YOU NEED TO!
|
|
<BR>
|
|
<P>Normally there are jumpers or resistor arrays on the scsi card or the termination
|
|
<BR>
|
|
can be activated via the bios. Some cards automatically activate the termination
|
|
<BR>
|
|
but you really have to make sure it is terminated!!!
|
|
<BR>
|
|
<P><P><EM>> Any other ideas to get this working?
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> d) and on another note - there's no power button on this thing, and
|
|
</EM><BR>
|
|
<EM>> the scanning bulb stays lit _all_ the time. Is that normal?

</EM><BR>

|
|
<P>The driver is responsible to turn out the light for the astra 2200, but I don`t have
|
|
<BR>
|
|
the command sequence for that.
|
|
<BR>
|
|
<P>In the moment: pull the power connector to turn off the scanner.
|
|
<BR>
|
|
<P><P>It also may be a problem of the scsi driver of your scsi cards.
|
|
<BR>
|
|
Lots of 1.x.x kernels had buggy scsi drivers. The 2.2.x kernel should be ok
|
|
<BR>
|
|
for the most scsi cards, so the 2.3.x also should be ok. But when the scsi card is a
|
|
<BR>
|
|
new product the driver may also be new and buggy.
