Im posting here too along with the electrical cuz Im not sure whice would be better..

I know someone here must have made there own cable.! I found the diagram. but I still need part #'s
I know what most of the stuff is like the 10k and 33k resistors but what is the 2670

I think the 4k7 and the 3k9 are 4and3 ohm with 7and 9% variations allowance? Anybody know.

I found all the parts at radio shack The 33k and 10K. and the DB 25 CABLE.

Here is the diagram if somebody can help me figure out the last bit of info I need.
THANKS
A list of part #'s would be GREAT!!

You realize doing this is illegal?

Kevin91Z,

Why is it illegal to make your own PC interface cable?

Well, if you had a legitimate copy of Diacom+, you'd have the cable. I had a cable go bad on me, and Rinda nicely gave a new cable at no cost. So any legitimate Diacom user can get that cable at anytime.

 

Nobody answered my question yet though.

 

383TPI,
The 2670 is a resister value in ohms. Get a 2.6k or 2.7k resister and you'll be fine.

As far as the legal question, I'm sure he's just doing a little research and experimenting to broaden his electrical background. I did the same cable. It works fine, almost.

The Diacom cable is specifically made so you cant copy it, then give the software to your friends (thats called pirating). Its called a "dongle" in software terms. When you make your own cable, you are defeating Diacom's copy-protection, which is a violation of their license agreement, which makes it illegal.

 

i bought diacom recently and need another copy of it, the plus version, can anyone help me out please? just want to upgrade

Interesting discussion on this issue.

Here's my take on it.

If a guy wants to make a cable and hasn't entered into any agreement with the makers of Diacom, unless Diacom has patented the cable specs, there's no legal issue.

If Diacom wishes to prevent others from copying its cable then it has to patent the design. It would then become an issue of infringement on patent rights.

Of course, using Diacom's schematics to build the cable muddies the waters quite a bit.

If the cable made by another differs somewhat from Diacom's design, even though the end result is the same (i.e. it allows the data to be transmitted from the ALDL)there's no infringement.

That's how we get so many improvements on existing designs. Build a better mouse trap and the world will beat a path to your door.

To thosse of you who are companing about PIRATING. Let me ask you one question. Im not beening an A$$ but..... You mean to tell me none of you have SOFTWARE on your PC thats BORROWED. Not a single one. No MP3's etc etc etc......


Thats for the info on the 2670 now what about the 3k4 is it a typo or a 3ohm 4% tolerance.?

I agree but Diacom never released their schematics. That drawing was reverse engineered by someone that had a background in electronics. Here's where it came from. http://www.techedge.com.au/vehicle/a...com/diacom.htm

The 3K4 is a 3.4K resister or 3400 ohms.

john, Thanks for the info and site.

The picture I got came from this site though. http://www.seanster.com http://www.seanster.com/scantool/com...face_Cable.gif

The reason I have to ***** about this, is because its illegal. It doesnt matter what I have on my computer, because this is Dirk's computer. He and thirdgen.org can get in BIG trouble if Rinda finds this. This should be deleted. You guys will have to email each other.

 

Kevin has a valid point that IF www.thirdgen.org was to condone and promote software piracy, two things are likely to happen:

1) www.thirdgen.org COULD be charged under conspiracy laws of being involved in software piracy.

2) You've identified yourself as a software piracy, subject to prosecution under US Copyright laws.

It personally is no sweat off my butt if you "share" software among yourself and others. But I would hate to see Dirk get in trouble for having a website that "facilitates" the priacy of software.

On a personal note, I learnt the value of "licensed" software years ago. There has been a few times in the many years that I have been using computers that I had some "glitch" that eventually required me to contact the software developer. In all cases, there was either a "patch" they had to send me or a setting I had to put in the Registry.

Without a valid license, I would have never been able to get the software to work. I truly believe that some vendors actually put out "poor code" on their initial CDs and the only way you can get the "fixes" is to be registered. I don't like it, but I can understand why they do it.

On a note about a legitimate version of Diacom (I think it is a good idea to promote the advantages of a licensed copy), Rinda does offer cheap upgrades to update your version to handle vehicles newer than 1995s (which is what version 2.85 does).

They are always a few years behind the current model year, but if you plan to own other GM cars in the future, wouldn't it be nice to have Diacom work on those? It really is a great tool. I feel that I have gotten my money's worth from them. I discovered MANY interesting things about my car which I would never have learnt without their software and saved me time and money in the process.

Good luck with your endeavours.

 

I never admited to "owning " the software. maybe borrowing it from a friend to work some bugs out of my car. hey his cable is bad. So I have to make a new one.lol.

Anyways, I see your point. I see my point. I am using v2.85 and If I like it may buy it.after all look how much I have in my Z. $500 would be fine. but why buy it with out trying it. Would be a waste of money if I find myself not linking it.

 

That is a very good point TPI383. With my SD ecm, I capture a lot of interesting information at a good baud rate. However, some of the earlier ecms have very limited information and work at the slow baud rate.

If I owned one of those cars, Diacom+ is not as useful other than for diagnosing an errant sensor. It doesn't have as much use to a "tuner" that is trying burn his own PROM. Talk to Pablo, and ask him what he thinks of using a scan tool on an older ecm? I am pretty sure that he would reply that it is not a good use of your money and you need to obtain more meaningful information from other methods.

And he's right.

PS: There is no need to make a cable for your friend. He can get a new cable from Rinda. They didn't even charge me when one of my cables stopped working and sent it out very quickly.
