suche mal nach "direct audio input cable" (DAI) bei amazon, ebay etc...

DIN-Normen befinden sich fest in der Hand des Beuth-Verlags. 
Europanormen sind dagegen frei abrufbar, soweit ich weiß. Es gibt aber 
gelegentlich Hersteller, die Auszüge aus einer DIN-Norm zitieren, wenn 
es zu ihren Produkten passt. Google hilft sowas zu finden, wenn man die 
genaue Nummer kennt.

I know it's private property.

I also would like to know the technical specs of my Roger X receiver 
(with euro plug) so that I can rig it to a Bernafon Soundgate 3 direct 
audio input. Those silly people only made a TRRS stereo input jack 
connector and removed the euro port which still is in the original 
technology of Oticon's Streamer Pro.

The only source of accessible information seems to be patents, which 
don't really bother with things as input voltage and output levels, but 
do give a general outline of how the technology works.

I am sure this is common information, but I just can't find it.

Edited. My assumption obviously was wrong, but pinout is shown by 
somebody else already in another forum:

I'd connect it like this:

3

To have it documented here, the pinout of DAI according to

That's me!! Lol.

I think that this would work for cables from a device (e.g. mobile 
phone) to a 3pin euro port.

However, since the Roger X actually needs its power to work and generate 
an output, I can't leave the center pin unconnected. Rather I am 
thinking to connect GRD and center to a hearing aid battery, GRD to the 
2nd ring, --some older TSSR's have GRD at the sleeve, but modern ones 
apparently use it for the microphone of the headset according to a wiki, 
-- and OUT to top and 1st ring.

What are those --[1K]-- in your scheme? Resistors? Those will work to 
attenuate the signal from a mobile phone to my hearing aids. However, 
the Soundgate 3 expects a mobile phone level, while it will be getting a 
microphone level. So I am likely to have the reverse problem of 
amplifying the signal. Can I simply put a battery between OUT and top to 
amplify?

So my main problems are:
- Will the Roger X be able to handle the battery or is it too much 
voltage?
- How can I amplify the signal if needed?
- Is it correct that the GRD is minus and center is positive voltage?

Last question is answered by this wiki: 
http://en.wikipedia.org/wiki/IC_power-supply_pin . Apparently, I should 
start thinking digitally instead of analog.

The information about the TSSR stereo jack was found here: 
http://en.wikipedia.org/wiki/Phone_connector_(audio)#TRRS_standards

The resistors aren't attenuating. They're meant as protection for Roger 
X's output.

As Roger X apparently requires a battery, I'd suggest to wire it up as 
follows:

1

DAI Connector                                TRS or TRRS Connector 

2

(Roger X)                                    (Soundgate 3)

                                +--[ 1 K ]-- TIP (left channel)

14

           |   BATT (-)                  |

15

GND -------+-----------------------------+-- SLEEVE (Ground or Mic)

You could either use a TRRS jack (connect RING 2 and SLEEVE to GND), or 
a simple TRS jack (SLEEVE is longer and will do the same job - 
connecting MIC and GND).

Regarding "GND", "VCC" etc.

GND = Battery (-) = Audio "Ground"
VCC = Battery (+)


Regarding audio level & amplification:

Signal amplification is not possible by just adding a battery!
You would need to put an amplifier in between "Roger X" and "Soundgate 
3".
I didn't find any information about output levels of Roger X and input 
sensitivity of Soundgate 3.
Perhaps Roger X's output level is sufficient without amplification...?

Roger X is a receiver for a wireless microphone, but this doesn't 
necessarily mean it has a microphone output level.
I pretty much guess the output level is around line level.

Ah. OK. So you propose to put 1kOhm resistors to terminate the 
transmission lines. Is brown-black-red the right color code?

This is shaping up really nice! Especially this way of protecting the 
Roger X (normally >400€, but I got an used one for 40€) looks like a 
good plan.

I will try it out with a hearing aid battery. Normally the Roger X is 
powered by it. Too bad I don't know whether the voltage is attenuated.

Thank you so much for your replies!

Tried it with a 312 battery, which generated 1.245V between the Roger X 
GRD and V_DD(+), and a 500 Ohm resistor at the OUT before the split to 
tip and ring of a common stereo jack. Checked whether the GRD of the 
jack was not connected to the tip and ring.

Results:
 - Roger Pen doesn't connects with the Roger X.
 - Roger X doesn't generate any sound, nor indication beeps.

Further experiments:
 - Could try it with a TSSR jack.
 - Could check what the voltage is of the Octicon Streamer Pro battery, 
before changing the voltage.

It's a bit hard to give any advice without knowing the exact technical 
specifications and "normal behaviors" of all those products. I recommend 
to contact the vendors and ask for required (min/max) battery voltage 
and in- and output levels. Ask them also to verify/confirm the DAI 
pinout.
To me it sounds like Roger X doesn't work.

It is really hard to damage the RogerX with normal use, so I am not 
thinking it is damaged. I rather think that the RogerX output is at a 
microphone level--basically not registering at the normal DAI port of 
the Soundgate 3.

Another approach could than be to use the telecoil connector. On the 
middle image you can see the 4 pin connector at the right bottom. Does 
anyone know what signal strength a telecoil generates?

The battery of the Soundgate has a voltage of 3.7V .

Wie sieht der Stecker denn jetzt aus? Manchmal kann man solche
Steckergehäuse nachgiessen, im einfachsten Fall mit Heisskleber.

Comparing the internal photo's from the FCC reports, I am wondering 
whether all the hardware isn't already there---that is all except the 
actual Euro port.

In the included photo's the Soundgate2 is on the left side, the 
StreamerPro on the right. The image resolution is of course abysmal, but 
at 600% magnification it does allow the check whether the electronic 
parts are present or not. It seems only the Euro port is missing!! 
Hopefully the firmware of the Soundgate also has capability to run it.

There are 5 soldered connection points for the euro port on the 
StreamerPro. I would assume that 3 are the  basic GRD, V_DD and OUT and 
2 are a switch to account for jack present/not present. Does someone 
know how such a euro port is normally configured?
