    RENAULT RADIOSAT 6010 (22DC461/62) protocol

    Anybody succeded to emulate CD changer on above mentioned Head unit ?

    It's missing the pull-up resistor on the left side transistor. See message 442 for a working circuit (at least it worked when I last tried it, unfortunately I hadn't time to play with it lately and I won't either in the coming months).

    thanks

    Is it enough to put 12 V permanent voltage on HU REMOTE
    through resistor ( problem is that my unit does not have HU REMOTE signal)

    Thanks for help pippolippi

    Yes, the HU REMOTE was an easy way to obtain 12v for the pull-up
    ( problem is that my unit does not have HU REMOTE signal)
    So I wonder if it is compatible (both electrical and protocol wise) with the tuner list unit. Google tells me it's a philips unit, so it's possible that uses a completely different interface.

    it only gives an ansver if you give it a try

    i have been searching also and it says thar it is compatible with vdo dayton cd changers which i have found that they are compatible with tuner and update list HU. it does not have spdif but analog audio input which is i thing advantage. from the electrical point of view i expect compatibility in level of signals otherwise it will not vdo cd changers will not be compatible with tuner list and update list, but for protocol it is only possible to try and see what happens.

    i am preparing to try first with pc version of emulator and if succesful i am planning to meke PIC version.

    actualy i am planning to install DWW-700M vga monitor with built un TV tuner
    and later PC with GPS mapping software and i need an audio entry to existing HU.

    I was also thinking to enter with the audio signal somewhere behind magnetic tape head reader (it is cassete player with cd changer control), but i think approach with simulation of cd changer is much more elegant way.

    Just one more question. Are the signal ground for D2B and common car ground connected together or not.

    I have also found some of yours schematics and would like to hear your comments which one is realy final and which one works best

    Thanks

    Pc Version Of Head Unit Emulator

    has anybody already made a pc version emulator of head unit

    it may be useful to test the cd changer emulator just by

    connecting software emulators on different com ports

    and test PCB boards without taking all the stuff in to the car & back

    Can anybody tell me wich kind of relay switches must I use to switch between CD Charger and PC??

    I'm trying to mount this circuit, but relays are not documented.

    Thanks in advance!

    I just replied to your PM :-). But it can be of interest to everyone indeed :

    You're right. I should be more precise.

    For relays, I used 2 small DPDT (bipolar bi-directional) 12V relays such as [http://www.velleman.be/be/en/product...id=17785]these ones[/url].

    And indeed transistors are standard bc337 ones.

    For debugging purpose, maybe you can start on a breadboard with only the main "level adaptation" part (central part with the opto-coupler) and once it works, you can go on with the relay switching part...

    Please don't hesitate to share your experience here - good or bad - and please specify your car and HU model if possible.

    Good luck ! =-)

    It's more universal indeed, even though quality can be a bit less than pure digital... Anyway, you don't have any choice

    Agreed.
    Just one more question. Are the signal ground for D2B and common car ground connected together or not.
    I wouldn't assume that. If you can, opto isolation is always safer I think.
    I have also found some of yours schematics and would like to hear your comments which one is realy final and which one works best
    Well, all are somewhat final at a certain point
    As I said above, I strongly advise using an opto-isolated one though my early developments were made without it.
    I'm personally using the last one ("Full version") on this page and it works pretty well, but the second one ("Opto-isolated version") should work perfectly if you don't need relay switching with an actual CDC.

    Please tell us the results of your experience, we're very interested...

    Good luck
