the 14 connectors are on the right, not the left These are ( from down to up ) analog-stereo ( headphone in ), Ipod, ICSP. You can see the pinouts on the schematics. On the left it is the connector for the head unit. The pin 1 = 13 pin of head unit

It is a double sided pcb. The top is top, and the elements are on the top side, as you can see the last picture.

Ok I started looking online for the components, and I cannot find the Schott 22083. Do you know where to find it or what can replace it ?
I have a friend that can print the circuit board for me, but he would like to have the design file in its original format so that if he doesn't have exactly the right components he can adapt the board, would it be possible for you to send this file ?
Thanks a lot!
PS: The components I have found so far seem to add up to about 65€, is it close to what you found or do I need to find a better supplier ?

What 65 euro? twice as much is new mp3 player

Foldesa

You can replace the transformer with PE-65612. Visit cirrus logics home page and look for the "Recommanded SPDIF transformers" data sheet. I'm not sure that this is the exact name but you can find in under products/cs8406.

The price for me was ~17 euro ( excluding the board ). You deffenetly have to look somewhere else.

The board was designed in protel 99se. The files are 17 Mbytes, so it is far too big to send by mail.

Your friend can design it from the schematics and can modify the footprints as desired.

Hi Foldesa,
do you know if this emulator can work on before-2000(non tuner list or update list) models??
The communication with the cd-changer should be the same, because the cd changer is the same too (a Philips RC026 renamed CDC026 after year 2000).
My HU supports D2B communication and here are some pictures
http://giovaland.altervista.org/gall...ryalbum&aid=75

The only difference between the HUs is that mine accepts analog left and right channels so... I think I don't even need the spdif converter .. am I right?

Do you have the schematics for the emulator only? How much $ do you think it should be?

Thanks in advance,
Giovanni.

Foldesa

Well s4uzer, I think there is more difference. I don't think the communication would be the same. The only thing is to try it with a home computer.
Please search the internet for more info before you try it because it may destroy your head unit.

Vicne, i need your advice

I am testing to use an ipaq to run the java CDCemu version
my ipaq (rx1950) has windows mobile 2005, insignia jeode java virtual machine
and i found on http://republika.pl/mho/java/comm/ the rxtx libraries for Windows CE and the IPAQ
i tried to modificate the TLCDCEmu.bat to adapt it to the windows CE example(if yo download the RXTX_iPAQ_0211.zip file inside comes all the installation instructions and a .lnk file similar to the .bat used on cdcemu)

yourapp.lnk
54#\windows\evm.exe -Djeode.evm.console.local.keep=true -cp \windows\Programs\yourapp.jar;\windows\lib\comm.ja r;\windows\lib\jcl.jar
YourApp -V

TLCDCEmu.bat
java -cp ./classes;./lib/RXTXcomm.jar org.tlcdcemu.main.TLCDCEmu
pause

i adapted the file in the next form:
54#\windows\evm.exe -Djeode.evm.console.local.keep=true -cp \classes;\windows\lib\comm.jar;\windows\lib\jcl.ja r TLCDCEmu -V

but i only obtan an error: java.Lang.NoClassDefFoundError:TLCDCEmu
Can someone helpme? do i have a syntaxis error? or its more complicated and do i have to modificate the java source code?

Thanks in advance

Little offtopic about sub-out.
I have "Tuner List" (22DC277/62) and when I am looking at this site I still can not figure out if it is possible to connect external amplifier for my subwoofer...? And how?

FroMage

Foldesa:

Thanks, I had already looked at the Recommended Transformers, but they only list manufacturers and not models, and once on the manufacturer's site I was unable to locate any actual transformer since I don't even understand what exactly they are supposed to do.
Unfortunately both my online suppliers don't have the alternative PE-65612, so I'd like to ask you where you got your parts? Perhaps I can order them from the same place since they also seem to be cheaper.
About your 19meg file, my friend tells me they compress really well, have you tried compressing it to see how much space they take ?
Thanks a lot.

Foldesa

Well, FroMage I don't know the exact part numbers. If you read the data sheet for the recommanded trs then it clearly describes what feqs and resistance, truns etc it must be. You have to ask your supplyer if they have a tr that meets these requirement. Personally I have ordered a sample form scott corp for free

I'm currently implanting this to Eagle, and it will be mutch smaller.

sencis

...maybe simple line-out? I can't wait to hear my subwoofer
please help
thx

Vicne

Oops, sorry, I don't have much time to hang around here anymore...
I'll make a long answer to compensate for your waiting time :-)


That is absolutely normal.

For a java program, the command line typically includes the following things :
- the java virtual machine (JVM) executable (looks like 54#\windows\evm.exe in your case)
- some options to the JVM
- the so-called "classpath", which tells the JVM where to find the code to execute, called classes (libraries or your own code). They can be either plain directories or zipped in "jar" files. In our case, the classpath needs to include the rxtx library and the actual emulator part
- the name of the "main" class to start (entry point of your program). This class can be part of a "package" (the "org.tlcdcemu.main" prefix in our case). Some prefer to write code where the entry point is not in any package like in your example, but I don't :-)
- some options to the program you want to run

So, in our case, I think the line would be something like :

54#\windows\evm.exe -Djeode.evm.console.local.keep=true -cp .\classes;\windows\lib\comm.jar;\windows\lib\jcl.j ar org.tlcdcemu.main.TLCDCEmu

It looks like the "-Djeode.evm.console.local.keep=true" option of the Jeode JVM instructs it to keep its output on screen, which is useful when debugging. When it works you can remove it...

For the classpath, first note the dot (.) before \classes. It tells the JVM that it has to search the classes subdir *relative* to the place where your lnk file is. You can replace it with a full path like \windows\programs\TLCDCEmu\classes - without a dot at the start this time - if you like (depending on where you placed the files)

The Rxtx library I had on PC included the JCL library if I'm not mistaken, but if they are separate in your distribution, you have to include both.

And finally "org.tlcdcemu.main.TLCDCEmu" is the class to start


Normally, Java is "write once, run anywhere", so no modification should be needed. In this particular case however, RxTx history has made them change the package name between versions from "javax.comm" to "gnu.io", which makes different versions incompatible unless you modify the calling code. I don't know which package is in use in the version of RxTx you got, but let's try with that first, and don't hesitate to tell us how it's going.

Yeah Eagle is exactly what we want ! You're amazing. I've tried the way of the free samples, especially for the cs5330 (14€ here), but they don't give samples for these, only the 5343 which is similar except i2s output format (which the 8406 supports i think) and 24bit sampling (which i hope will work). Some restistors and such are a bit different, but I hope I'll manage. BTW, I've noticed that the 5330 advices some 1k resistors on the digital outputs, and the 0.1uF condo on the analog input is supposed to be between the 0.47uF condo and the cs5330, does it matter ?
How did you get samples from Schott ? I sent an email to the sales contact because I could not find a link on the site to do this. I'm starting to wonder in which country you live, you certainly cannot be in the US with a Renault car, can you ?
Vicne: I'm starting to feel guilty of hijacking this thread to a different topic although related, do you feel this way and do you want us to move to a different thread ?

Foldesa

What ????? 14 euro for the cs5530. I can't belive it. I live in Hungary, Europe ( you had to see the riot on tv ), and cs5530 is 1400 Huf witch is ~5 euro.
Try this link: http://www.em.avnet.com/memec
I got the samples because my company sometimes makes order from them.

Foldesa

You have to rewire the cs8406 if you put an i2s A/D ic. And probably modificate the op amp too.
