Hallo, dieser Stecker ist anscheinend bei Hörgeräten und Implantaten Standard, um Zubehör anzuschließen. Mir ist ein solches Kabel kaputt gegangen (Katze hat den Stecker zerkaut, also leider nichts mit löten) und ich suche deshalb ein neues. Der Hersteller meines Hörgeräts will >60 Euro haben. Da in dem Kabel null Elektronik drin ist sehe ich das nicht ein. Ich weiß den Suchbegriff allerdings nicht und habe mit viel Glück was bei aliexpress gefunden. Da ich das Kabel aber gerne bald hätte würde ich gern innerhalb der EU bestellen. Vor allem habe ich aber keine chinesische Kreditkarte. Weiß jemand, wie dieser Stecker heißt, der da am Kabel abgegossen ist? http://de.aliexpress.com/item/Black-high-quality-3pin-cord-hearing-aid-soft-cable-cord/1125607961.html Dann könnte ich mal vernünftig danach suchen. Gibts doch nicht, dass es so was hierzulande nicht zu akzeptablen Preisen zu kaufen gibt. Danke.
was spräche denn jetzt dagegen, das Zeugs bei aliexpress zu kaufen? Paymen Methods: Visa, Maestro: bietet jede deutsche Bank an. Da braucht man keone chinesische Kreeditkarte für Selbs der übelst teuere "Western Union" ist in jeder Postfiliale möglich.

Could anyone post a link to those DIN norms that doesn't involve paying twenty-something euros? Thanks
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. z.B. http://www.dhi-online.de/DhiNeu/08_Berichte/11_Norm_118-7/Norm_118_7_02.html ein Powerpoint-Vortrag über Hörgerätenormen, gefunden mit der DIN-Nummer

like it or not, but standardisation documents are private interlectual property. DIN Normen are private interlectual property of Deutsches Institut für Normung. The publisher Beuth Verlag has a non-exclusive right to publish them. Allthough the publishers rights are non-exclusive, there are no other publishers. European Standards are private interlectual property of the national european standardisation organisations. You can buy them at any national european standardisation organisation, you like. I've heard, that ESTONIAN CENTRE FOR STANDARDISATION evs.ee has some good bargains. Posting a link to a free accessable standard document will be violating the private interlectual property rights.
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: http://www.hearingaidforums.com/archive/index.php/t-17572.html http://l-userpic.livejournal.com/30460700/6554328

I'd connect it like this:
1 | DAI Connector TRS Connector |
2 | |
3 | GND ----------------------------------- SLEEVE (ground) |
4 | |
5 | VCC - leave unconnected |
6 | |
7 | OUT ---------------------+--[ 1 K ]---- RING (right channel) |
8 | | |
9 | +--[ 1 K ]---- TIP (left channel) |
To have it documented here, the pinout of DAI according to http://l-userpic.livejournal.com/30460700/6554328:
1 | GND VCC OUT |
2 | +-+ |
3 | | | |
4 | +--+ | | +-+ |
5 | ) ( | | ) ( |
6 | | | | | | | |
7 | +------------+ |
8 | | | |

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) |
3 | |
4 | +--[ 1 K ]-- TIP (left channel) |
5 | | |
6 | OUT ----------------------------+--[ 1 K ]-- RING 1 (right channel) |
7 | |
8 | |
9 | VCC -------+ BATT (+) |
10 | | |
11 | --------- battery with suitable |
12 | ----- voltage for "Roger X" |
13 | | +-- RING 2 (Ground or Mic) |
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.

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 .

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?
