Digital BW, The Print

OffTopic, but this seems to be The forum for a broad knowledge database : 
I just purchased an older Polaroid SprintScan 45. What, praytell is the SCSI connector this unit, and how long of a cable may I use ?   The Polaroid info says 1.5 feet - I'd really need ~12 feet. 
Any experience anyone ???

Thanks,
Alex

I doubt Polaroid says 1.5 FEET, meters more than likely.  I also doubt that,
since this unit is a SCSI II unit, but really behaves as a SCSI I unit.  I'd
say you're fine with 12 feet, IF and ONLY IF you use ACTIVE termination,
which I am hoping that scanner has internally.

The page you quoted, Tim, says 1.5M for Fast SCSI, which I don't believe
this scanner is, but it may very well be.  MOST scanners are barely SCSI
II...

I'll take a look at that scanners specs and see what it says.

Alex,

SCSI does have definite cable length limits. The user manual, page 33, for
the SprintScan 45

http://www.polaroid.com/service/userguides/digital/ss_45_ug.pdf

says 19' total so at 12' you should be okay. Don't forget to count internal
cable length and any other cables in the chain.

For good info on SCSI and good cables check out Granite Digital:

http://www.scsipro.com/

and Adaptec's site:

http://www.adaptec.com/

By examining the connectors on the scanner (you probably have two choices,
50-pin Centronic and D25-pin) and the connection on your computer you should
be able to figure out what cable you need. This is rather confusing as there
are 4 or 5 different kinds of SCSI plugs

Tim, Austin,

The specs say SCSI-2 so he could squeak by at 12'. Is there any risk of
increasing the chances of signal noise as the cable length gets that long?

You are correct, Martin, according to page 2-2 of this scanner manual you so
thoughtfully provided the URL for ;-), it shows a DB25 (do NOT use) and a
Centronics 50.  Use the Centronics 50, so a cable that has Centronics 50
(called SCSI I BTW, by most cable vendors) and a whatever on the other end
that matches your SCSI card, which should be what's called an HD50 (mini-50
pin D connector, HD meaning High Density).

According to page 2-8, this scanner MUST be externally terminated...so you
will also need an ACTIVE (NOTE ACTIVE is VERY important) in-line Centronics
terminator.  I have ordered SCSI stuff from www.scsistuff.com, so I
recommend them highly.  Whether they have an ACTIVE in-line 50 Centronics
terminator, I don't know...but I'd suggest really searching for one, and
don't settle for one that is not active!  Especially if you are going to use
a (if you can find one) 12' cable.  You may be able to only find a 6' cable,
and you really don't want to "chain" cables, as you degrade the signals.

I agree with Austin...

You may even be able to get an external active terminator and get it to 
work  if the scanner is a passive termination device..

That's why it's called "SCSI VOODOO,"  things with SCSI just defy logic 
and specs all the time..

Hi All,

This is Austin's wife.  I heard him choking and gagging, so I came running
downstairs.  I found him in a coma on the floor, holding his stomach...with
this email open, and his hand grasping the keyboard!  I'm not quite sure
what to make of it...but he usually is right, and makes sure we all know
it...

Austin's wife, Koralia...

Thanks Austin and Martin,
( nice automobile, btw)

Here's from the Polaroid FAQs page 

"Check SCSI connection and make sure everything is securely connected. Make sure you are using new, high quality cables that, when chained, do not exceed 9 ft. (3m) in total length. A single SCSI cable connecting the CPU to a device should not be longer than 1.5 ft."

There are two types of 50 pin connectors, I was not sure this had the Centronics or HD. ( I presumed since it Is a few years old, it would be the C50 style, but could not tell from the drawings) My PC has a HD68 connector... and I thought SCSI was the 'simple' interface !!!

I just wanted to have a cable available when the unit arrived to be able to test it...

Thanks To All ( as usual !! ),
Alex

Well, that does not conform to SCSI standards...  I'd say don't hesitate to
use a 6 foot cable.  Are you SURE it says 1.5 FEET?  If so, that's simply a
misprint, there are no 1.5 FOOT cables I know of!

You MUST then get a special HD 68 to 50 pin Centronics cable that has the
high byte terminated in the cable (if you can find out, but I doubt it), or
use a special HD68 to HD50 adapter, with the high byte terminated, then us
an HD50 to Centronics 50 cable.

HD68 to HD50 adapter, terminated high byte:

http://www.scsipro.com/catalog/pg01_adapters.htm

2305 68m  MicroD to 50f  MD w/Term.

I'd strongly suggest getting this one instead of the one with the Centronics
connector...as you can use this for future scanner cabling that uses HD50.

Then get an HD50 to Centronics 50 cable:

http://www.scsipro.com/catalog/pg09_xtcables.htm

Down about half way "50 Pin Centronics - to - 50 Pin MicroD (High Density)"
they have 6, 10, and 15 foot and are VERY expensive.  I'd suggest simply
finding a cheaper one, say, from www.scsistuff.com...but they don't appear
to have the adapter above...

And, you need an ACTIVE Centronics pass-through terminator, which I couldn't
find one on either web site, but you could use, against my better
judgment...a 25 pin ACTIVE terminator, which appears to be available:

http://www.scsipro.com/catalog/pg05_terminators.htm

5002 25 Pin Applem $29.00

Those guys are PRICY though!

Regards,

Austin

The SCSI cable manufacturers should just give away scanners and make up the profits in the cables and terminations !!

I think I will save a few $ and get the C50-C50 for the cable.

Granite makes an Active 50 pin Centronics unit PN 5509,
the HotSwap device. Seems it is a pass through termination as
shown in the Polaroid information, but I think it needs to be
F-M .... This is becoming painful !!

Thanks,
Alex

Alex,

If you want, email the part numbers and URLs of what you are considering
getting, as well as the model number of your SCSI card, and I'll check to
make sure they're the right cables/terminators.

Regards,

Austin

Alex,

Both my Polaroid SprintScan 4000 and SprintScan 120 had onboard internal
termination activated by a switch on the back and I never had to use any
additional termination. So you are probably okay in that department.
