Subject: SCSI CD burner
There aren't terminators on the back of the external case, just a switch,
which connects to a pair of pins on the back of the drive -- those pins
either need a jumper or they don't, I'm just not sure which.
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).
I don't recall if there's a parity jumper there or not but the drive itself is
marked, they just don't express the sense of the pins.
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.
That's the part I was wondering about...
Thanks.
