#How to terminate drive
9 messages in this thread
I just got a Sony CDU-7211W drive (external), and the instructions with the
Future Domain SCSI card I got for it say that the last drive connected to
the card must be terminated. The Sony will be the only drive on that card,
so I presume it must be terminated. However, the FD manual was both vague
and excessively technical about how termination is done. Lots about load,
impedance, ohms, plenty of electrical diagrams, but no illustration of the
device used to terminate the line or where to place it. The Sony manual
makes no reference to termination at all. My dealer doesn't know any more
about this than I do, and when I called Sony I got shifted from one
department to another, and was finally told that someone would get back to
me next week (!).
Can you help with specific instructions on terminating this drive?

Helen,
If I'm not mistaken the Sony drive has a terminator on it. Look at the
back of the drive — there should be a set of switches. One of them is a
terminator. The terminator must be turned on on the last drive in the
chain — if you only have one drive, turn the terminator on. I believe the
switch has "terminator" written next to it — if not, the Sony manual
should indicate which one it is.
I hope this helps.

The back of the Sony drive has R and L audio output jacks, two parallel
cable ports, a power cord port, and a mysterious round object which can be
turned with a Phillips screwdriver, with a symbol next to it representing
an upsidedown T with five slanted fins attached to its bottom. The manual
calls it the ground terminal, and says that connecting it to the computer
may reduce audio noise. The manual does not refer to terminating the drive
at all, that I can find.

That's weird — I would think that it should atleast have some switches to
set the drive ID. How do you set drive ID when you daisychain drives?
Frank
Actually, there is a little window with a number showing through it for the
drive ID, which can be incremented somehow — I left it at 0, since this is
my only SCSI drive.
Since the dealer said he thought the drive didn't need to be terminated, I
decided to go ahead and try it anyway. I installed the drivers, but
couldn't get the system to recognize the drive. After some discussion with
someone at MS tech. support (I thought I might need updated drivers), I
pinpointed the problem — the setup program had placed the MSCDEX line at
the end of my AUTOEXEC.BAT file, after a batch file that runs CHKDSK on
each drive, and it was not being reached. I moved it higher, and then was
able to access the drive both inside and outside of Windows.
Then I tried installing the MS Bookshelf, and ran into a problem with not
being able to save the SETUP.INF file. I found a fix for that in a message
about that very problem I saved from WinAdvanced a while back, and then I
installed the DeLorme Street Atlas, and had problems with it which turned
out to be related to installing it under Norton Desktop instead of Windows
— I reinstalled it with Program Manager as my shell, and still had the
problem, but then after talking to DeLorme tech. support I put the ATLAS
directory in as the working directory, and now it works fine.

Well Helen, it sound like you had a rough time of it. But I'm happy to
hear you're up and running — and I bet you are too. 🙂
Frank
Well, realistically it was no more than you can expect with installing a
new type of peripheral with its software under a new environment (Windows
3.1). None of the documentation referred to Win 3.1, some of it was out of
sync with other documentation, some of it hadn't been updated when the
hardware was changed, etc. Sure is great to have the drive working at
last, though. And Sony still hasn't returned my original call from last
week (when they said, after bouncing me from one department to another,
that they would have someone call me back in a week or so).

I just don't understand how a company like Sony can afford to tell a
customer who calls for support that someone will get back to them in a week
or so. Oh Well!
Yes, it is rather incredible. But generally you get better support on CIS
anyway.
