Subject: SCSI CD burner
I've been going crazy here trying to get a burner
working. One flat-out
won't
see a disc, even though I bought that one brand new
(though that was a
while
ago and I made the mistake of continually using it for
a CDROM drive as
well), another one has mechanical problems, and then there's this
external
unit...
It's a Yamaha CRW4260tx. I don't have a cable to connect from it to the
Adaptec 2940 card that's installed in the machine. I currently have a
50-pin
cable running from the inside connector on the Adaptec
card to the
internal
connector on the drive (with its cover off).
I'd like to put the drive in the box. Right now for both device number
and
termination these functions are handled by the
external drive's box, on
the
rear panel.
Can any of you guys help me with whether jumpers need to be _on_ or _off_
a
pair of pins to make termination happen and to assign
a device number?
I'd
measure it with a meter but don't have any handy
means to get into those
connectors at the moment...
If you are using a 50 pin cable from the internal scsi card to the drive
directly the terminators on the back of the external case are not connected
to anything.
There are 3 sets of jumpers on the back of the cdrw for SCSI ID, then
probably one for parity or something, then the next one should be labled
terminator (jumper that). If it is the only drive on the cable none of the
SCSI ID jumpers need to be connected and it will show up as SCSI ID 0.
