Analogue systems

Hi,

Does anyone have the pin setup for AS modules?  I have an american 
PSU (4 pin) but I'd like to get some AS modules.  Doepfer has their 
pin setup on their website so you can figure out what you'd need for 
the conversion, but so far I haven't been able to find that info on 
the Analog Systems site.
I'd appreciate any help.
Thanks

OK, I can answer this for you, but please *listen* closely for your own
module's safety.  Depending on the shunt fold back protection of your PSU,
getting them reversed may require you to change all of the semiconductors in
the effected devices.  I say this only because I enjoy (for lack of the real
word) dyslexia and am constantly getting things like this reversed.

The Analogue Systems modules get their power via a 16 pin dip socket (IC
socket).  What they've done is rather clever, double-doubling up the four
voltages in groups of four wires each of a standard ribbon cable, thus
allowing for very easy power distribution without compromising the current
limit of the comparatively small gage wires of the ribbon itself.

The power distribution and four pin groups on this socket are as follows:

Group 1 (Ground): pins 1,2,16,15

Group 2 (+12):  pins 3, 4,14,13

Group 3 (+5 - see footnote): pins 5,6, 12,11

Group 4 (-12): pins 7,8, 10, 9

These pin outs are identical on all A Sys boards.  Note that +5 will not be
required on every module you purchase and you should consult A. Sys
regarding which may be effected.  All modules that have a LCD display will
require it and there are more as well without displays.

If you don't wish to deal with the ribbon cable, I use what's called a 'surf
board" connected to only one side of the DIP socket (either pins 1 - 8 or 9
- 16), as it will allow for thicker gage wires and eliminate the need to
double them up.  It also makes it a hell of a lot easier to terminate the
other end to a four pin Molex, which I think you're describing here.

One thing I suggest - once you've connected it, BEFORE YOU LIGHT IT UP, test
these connects at THEIR SOURCES.  Buzz out the four voltages FROM THE POWER
SUPPLY TERMINALS to LOCATIONS ON THE MODULE'S PCBA WHERE YOU ARE CERTAIN
THESE VOLTAGES ARE ROUTED.  For instance,  an ohm meter,  beeper or wire
continuity tester from the positive 12 volt terminal on the PSU to pin 4 of
any TL074 or 084 IC.  From the negative 12  terminal of the PSU to pin 11 of
the same IC.  If you're getting continuity at those two places, you can be
certain ground is going where it should.  If it isn't at least the module
won't blow, it will just not allow for a return (current flow) and the thing
simply won't turn on when power is applied.

On TL072's and 82's, which are quite common on A. Sys modules,. +12 is found
at pin 8 and -12 at pin 4.  Doing this allows you to test your Molex
termination -and- your DIP socket end at once.

Make sure to wear a ground strap when sniffing around PCBAs.  There could be
CMOS afloat, just waiting for tha fateful discharge.

Hope this helps.

Thanks Peter, that's exactly what I was looking for and more. I do 
believe my PSU uses Molex connectors.  I'll be attempting to power up 
a Wasp filter, which I don't think needs the 5volt supply but I'll 
check on that.  I'm guessing, since its a ribbon cable, that there is 
a red mark to indicate pin 1?  I don't have the module yet so I'll 
have to wait and see.
Thanks again for your response.  Very helpful tips!

Sorry, its not the Wasp Filter, that's a Doepfer Module.  I've been 
looking at several different things.  But I believe Doepfer also uses 
10 and 16 pin interfaces.

Since you are discussing power supplies, and Bob Williams has just 
warned us again about those wimpy Doepfer power supplies, can 
anybody recomend a good power supply for a system combining AS and 
Doepfer modules?  (AS won't sell power supplies separately)  Any 
help would be appreciated.

Condors - they're available through Mouser.com and quite excellent.  The
shunt protection is so good you practically don't need a fuse (but use one
anyway!!!).

But - i'm not quite sure what Bob meant by this because outside of the
transformer type, the Doepfer and A Sys PSUs are very similar.  The D uses
fixed regulators, the A Sys uses variable for the +/-12.  That's about it.

I've used Doepfer PSUs to power booth at the same time without any problems.
I am actually currently using a Doe supply, with a self made 5 volt
regulator, to power my RS300 right now.

In any event, for the same $$ as a Doepfer, you can purchase a Condor - and
those supplies are the real deal.  This is what I'm using for my main system
and I couldn't be more pleased.  highly recommended.

hope this helps,

Peter

Thanks, Peter.  That looks like exactly what I need.  

I have several slightly modified Doepfer portable cases, and in one 
of them I have four RS-95s, which Bob Williams says draw 60ma each.  
So, I haven't been able to arrange modules the way I want due to 
current considerations.  The HAA15-0.8-A+ at .8 amps or the CP-131-
A+ at 1.1 amp looks like it should solve this problem.

Which power supply are you using in your giant system?  I'm guessing 
you must be running about 4 or 5 amps on that puppy. What are the 
dimensions of your power supply?

Thanks for the information.  It will all be useful as I expand.

All together I'm running four supplies.  I made a chassis which holds two
Condors, one set for 12 volt, one for 15, which powers most of the modules
in the large cabinet.  Each supply is good for about 1.5 amps.

The right side of the top wing, which I call the expansion unit, from the A
RS-60 on is powered by a separate Power One, an old Serge power supply
actually.  I did this because the RS290 was pulling way to much current and
making some awfully odd things happen - massive distortion in the delay,
unstable sequencer outputs, etc.  In short, the two Condors were starting to
crap out.

The forth supply, a Doepfer, is housed in its own little chassis box which
also holds my RS300 by itself.  I made my own 5 volt regulator boardlette
which worked out great.  I use a standard A Sys dual power cable (daisy
chains two connections).  This cable comes off the main supply where it gets
+/- 12 and ground and slaps them in the right palces onthe DIP cable.  It
first socket on that cable goes into my little card into an 16 pin IC
socket, and that card takes the +12 and regulates it to +5 and places THAT
in the proper locations for the A Sys power buss.  The last DIP connector on
the cable then plugs into the RS300 where it's now getting +/-12, +5 and
ground.

The RS300 pulls between 190 and about 350 mA, the Doepfer supply is good for
about 500, I'm covered, it works great.

A word about the large system - it's not as huge as it looks.  It only 28
inches wide by about 25 tall.  It just looks huge because of the lens on the
digital camera.  There is a lot sutffed in there, however as a lot of the
faceplates I had made so I could easily adapt Blacet, MOTM, Oakley, Doepfer.
Buchla, Wiard, Analogue Solutions, Analogue Systems and a ton of homebrew
gear into the same format or three RU high.  If you notice, the Blacet
module faceplate are a lot less wide as his stock ones.

The are a lot of changes in the system since the last photos were taken. the
expansion module now holds the RS290 and 295, and the two blank panels and
Doepfer A-192 are gone. The top row of the main cabinet is a lot different.
My programmable pulser has been pulled, the Moog Filter is gone (the PCBA
didn't fit in the cabinet ever and was never installed) , the outputs for
the MAQ 16/3 are gone, I have a new processor I designed in there, an
expanded boolean fucntion generator and an RS210 in which I've added
separate non attenuated outs for each filter.

And there are more planned as I am making room a Doepfer Source of
Uncertainty as it is released and I'm replacing the Blacet Final FIlter with
a Buchla Bandpass clone I've slapped together from Mark Verbos' art.

The A. Solution unity gain mixer may have to go forever to make room for
this stuff.  Although I hate doing this as mixers are always handy,  I
hardly ever use it.

Sorry for such a long posting.

best,

Peter
