I think that only some model of HU can support this featured, for example the HU that have CDTEXT.

Oh, yes, it works better with a "dash" character between "pi" and "180" :-)

Not that I completely understand french but....

Well, I do, but there's not much information there, just it seems there are 2 models available, the pi-180 being an interface for both stalk controls and display, but apart from the price (120 EUR), it needs to be plugged directly to the display, so the dashboard has to be dismantled.
Anyway, it just confirms it's positioned between HU and display, not between CDC and HU, and you can see the yellow female connector on this picture

Probably. I suppose the Tuner List probably discards that information...
All I can say is that several people have bought and use the CHM604 on planeterenault and their only complaint is that ID3 isn't displayed...

Interesting. The reply was about Javascript which isn't Java, but I get the idea.

@Vicne, excuse me if I send info about how to control girder via HU...

No problem :-)

I've tested the c:\programmi\girder\event.exe PLAY or c:\programmi\girder\event.exe STOP , etc, and after set this event in Girder whit RR.GML loaded I can control RR! It works fine, If you have a little free time to add it in your TLCDCEmu I can test in car, there will be a great step!

For my part, I'm investigating direct control of RR without Girder as I don't like to force people to buy Girder if not needed. I had a good advice of Guino and I have good hope.
So for the moment I'm keeping Girder as a backup track, but thanks very much for the information.

Remember ?

Ordered on Thursday, sent on Friday, received this morning via Fedex.
The funniest thing is they send a 20x20x10cm box for a 10x5x2mm chip :-)
As soon as I stop trembling and have a bit of time, I try to solder the chip :-)

I think to keep Girder solution as primary because i think this is the faster and easy way to comunicate whit RR and a lot of people have the free version of girder, and someone can configure it has he want.

Bye.

I found some (til111) and I've tested them at 19200bps (not in the car though), so they should work fine at 9600.
I've prepared the circuit with 3 optocouplers (one for tx, one for rx and one for the remote signal) on the breadboard and maybe tomorrow I'll have time to test it in the car.

For people who are still looking for a shop to buy mini ISO plugs, look here. Its interesting because there are no wires connected to the pins, so you fix your cables and lengths.

This is the circuit I'm going to use:


The program has to activate rts and deactivate dtr to give the correct voltages for the input side.
I take the signal from the emitters on input so it's at a positive level with 12v on the led and negative with 0v.
The output is connected as an open collector but the input signal is reversed, so the HU, through it's internal pull-up, will see a positive voltage (transistor open) when tx is positive and 0v (transistor in saturation) when tx is negative.
As I said I tested this circuit by connecting a pull-up resistor on the bottom optocoupler to a 12v supply, and connecting the resulting signal to the middle one (through the 680ohm resistor). I could read back the data sent at 19200bps.
