Hi.

I have seached over and over in the forum but could not find a topic on this.

I have the V70N -06 with the melbuscable preistalled without any nav or jukebox installed.

Can I buy the PA11-VOl and hook it in to the connector that is free in the trunk 9pin DIN I think it is. Or will it BURN
the PA11 as someone said that the pinout is not one-one in the melbuscable from stereo to trunk.

You normally hook the PA11 into the back of the stereo direct but I would like to do this without disassembly the dashboard.

The problem is that you have a male end on the melbus cable, and the USASPEC's cable also terminates in a male.

You CANNOT plug the melbus directly into the PA-11, because the PA-11 needs it's power supply fed in through one of the wires. It probably won't hurt the PA-11, but it won't function without power. You could use the navigation adapter cable to do it though, but I don't know if they've fixed the cable design yet.

You could construct a female-female converter cable if you know how to solder. Simple & cheap. There are threads around here that show the pinout of the Melbus connector. http://forums.swedespeed.com/z...age=2 (pic of connector on page 1)

Note that the audio left, right and voice channel need to be shielded separately with the analog ground.

Re: PA11-Vol + MELBUScable is it possible (mrg_Ed)

Hi and thanks for your response.

I found this in the other threads (thanks to you)



8-Pin DIN Pin outs...

E1 - clock signal (MELBUS)
E2 - analog ground
E3 - +Batt (key=run)
E4 - Data (MELBUS)
E5 - Busy (MELBUS)
E6 - L audio
E7 - R audio
E8 - Voice Guide audio
H - shield ground

According to this there is both audio and power in the cable (E3) so it should possible to buy two female 8-pin DINs and solder togehter, its real simple.

But how should it be connected Is E3 +12V in the PA11-VOL also so it do not kill it


Is it E1-E1, E2-E2 etc

Re: PA11-Vol + MELBUScable is it possible (volvo_man)

After a second thougt, If it was a one-to-one mapping there would be no need of an extra cabel at all, the Melbus cable (male) could then be plugged directly into the PA-11 Vol

But I have a seen on the fourm that it will burn your PA11-Vol
as the pinout is diffrent, Cant find the thread
. Anyone know how to connect it

I'm not sure on the PA11's power supply, you could ask USAspec. The power supply lead on the stock cable runs through a filter of some sort, but I never bothered to measure the output on the other end. I'm guessing that if the power on the 'run' line of the Melbus cable was sufficient, they wouldn't have bothered injecting power into their cable separately.

Re: PA11-Vol + MELBUScable is it possible (partridge)

Ok, thanks for your valuable inputs.

I think I can take a chanse that the MelBusCable is "straight trough" with 8-pin DIN males in both ends.

Then I just make a "straight trough" 8-PIN feamle DIN and then plug in the supplied PA11-VOL cable in the end and feed the power from the battery in the trunk.

Do I need any new software in the car/stereo for the PA11 to work or is it preisntalled in the HU-650?

As far as I know, the Melbus cable is a 'straight through'. I have the PA-11 in my trunk split with the RTI navi instead of behind the headunit. I got tired of pulling the headunit every time I had to test a new configuration to get rid of the noise...

Re: PA11-Vol + MELBUScable is it possible (partridge)

Ok, thanks for you help.

I have now ordered the PA-11 VOL and will try to install it in the trunk as I have the melbus cable preistalled and it is just hanging loose as I do not have any CD/NAV/Jukebox. (is it hard to find the end of the melbuscable, do I need to remove any of the interior to reach it, did try to peek but did not se much)

I will make a Female 8-8 DIN connector and use the PA-11 supplied cable to get ground and +12 v the correct way trough the PA11 cable.

Do I need any new sofware in the HU-650 or will it detect the PA-11 automatically? anyone knows this?

Re: PA11-Vol + MELBUScable is it possible (volvo_man)

Seems my attempts failed


I recived my PA11-VOL a few days ago ot my V70n -06 (HU-650) equipped with melbuscable but no CD-changre or nav.

I did buy two 8 DIN female connectors and soldered a short "straight trough" adapter.

Plugged the DIN-adapter into the melbuscable in one end and the PA11-VOL cable to the other. Added +12V and ground to the PA11-vol cable.

Connected the the PA11-vol and put both switches to off as I will use the two RCA inputs for my own portable player.

When I start the stereo and go to CD it serches for 10-20 seconds, then I get CD-ERROR in the display.

Now I stuck and do not know what to do next

CD-ERROR means: no proper communication between adapter and HU. Can you post a picture of your female cable (or send it by email)?

Re: PA11-Vol + MELBUScable is it possible (mrg_Ed)

Hi mrg_Ed (the Guru http://********************/smile/emthup.gif )

I can fix a picture later when I get access to my camera, but what I did was to buy was two 8-pin DIN female connectors.



I put the connectors "back-to-back" and connected the pins one-to-one straight trough "physically" if you look in the pinout in the picture below this results in the a configuration looking like:

Pin - Pin
1 - 3
2 - 2
3 - 1
4 - 5
5 - 4
6 - 7
7 - 6
8 - 8

As one of the connector becomes "mirrored" when I put them back to back

Maybe I should have crossed the small cables I soldered to create someting like this

Pin - Pin
1 - 1
2 - 2
3 - 3
4 - 4
5 - 5
6 - 6
7 - 7
8 - 8

I thought something like this had happened. This is where it went wrong, a 1-1 cable always needs to connect the pin-pairs, meaning pin 1-1, 2-2, etc. This is valid for the entire signal path.

Yep, that's the way to do it. All Melbus cables have a 1-1 connection. This way, if you look at the end-to-end female connectors, the pins never get mirrored. In your case, the end-to-end connection is mirrored, because somewhere in the signal path (your female-female cable) the pins got switched.

Hope you didn't wreck your HU, since the 12V got on a pin where it didn't belong...

Keep us posted of your progress.

My HU seems to have survived, maybe the PA11 did get toasted
by the +12V on the wrong pin fed from the HU:mad:

I will reconfigure tonight to see if it works or if I did burn the PA11
