The samsung adaptor is missing the data pins for usb. This is on the 11pin to the phone side

Got one and this was the first thing i checked.

From what i can tell the adaptor uses the pins on the phone as

5 micro usb standard pins

Id

Power plus

Power neg

Unkown

Unkown

6 upper pins to total 11pin adaptor

Video out plus

Video out neg

Audio out plus

Audio out neg

Unkown

Unkown.

The actual pin locations ie number, i do not know.

I did get certain functionality from my tv remote ie play, pause, stop that did work.

So using the 11pin samsung adaptor i could sit back play music and look at my phone.

I also tried using the usb port on my tv for a wireless mouse and keyboard to no effect.

I have a sony bravia 42" tv couple of years old and its part of the rented house so i dont know model number.

This is just the stuff ive found out about the adaptor
[Galaxy S III Accessories] jay2the1:
damn I was really hoping that you could use MHL and USB OTG at the same time, thanks for looking into it in so much depth though.

How is the Allshare Cast device? is there any lag between the phone and the screen like there is with Airplay on iOS devices?
[Galaxy S III Accessories] blueeagle69:
Yep, me too.

I was hoping to use my ps3 controller in wired mode with the MHL adapter. Because I didn't want to root in order to use it wireless :(
[Galaxy S III Accessories] joysleep:
Can some1 please tell me something

If i use the MHL adapter with my S3 and hook it up to my TV using the HMDI cable, would sound come out of my TV.

But would it also come out my phone. So can i use bluetooth headphones to listen to my video?

Thanks
[Galaxy S III Accessories] blueeagle69:
Hi.

Yes it will.

Hope this helps.
[Galaxy S III Accessories] joysleep:
So are you saying that the sound will come out of my TV and phone while using the MHL adapter?

So i can use a pair of bluetooth headphones connected to the device to listen to my video which is being displayed on my telly.

Btw i hear there is a way to get MHL working with USB OTG at the same time?

I dont know how

Any1?
[Galaxy S III Accessories] blueeagle69:
I think sound will divert to the mhl instead. Although don't quote me on this because I haven't got one yet :)

I asked the very same question concerning Otg and mhl at the same time, because I wanted to use my ps3 controller and mhl at the same time. But it doesn't seem to be possible.

So I rooted so I could use it using Bluetooth :)
[Galaxy S III Accessories] DKYang:
Sound will come out of the TV.
[Galaxy S III Accessories] joysleep:
Bluetooth headphones

So even if i paired up my bluetooth headphones, i still wont hear anything if i am using the MHL. That doesnt make sense because the headphones is hooked up, would there be a way to tell the phone to transmit the sound to the bluetooth headphones?
[Galaxy S III Accessories] slay3r85:
If we buy the 11pin from samsung and use the other cable in this website, we should be able to plug it to power mhl using the female plug while the male inside mhl and use otg correctly no?

I am just not sure about the current direction as i dont want to fry my mhl nor phone.
[Galaxy S III Accessories] scarrmrcc:
ok.. think I am on to something!

this cable:

http://www.ebay.ca/itm/Sam-sung-Gal...ultDomain_0&hash=item1e724db681#ht_4778wt_835

has all 11 pins in the connector. they are all hooked to wires, but the pins are there.

interestingly, not all the pins have wires at all....

of the 5 usb, they have ground, power, and pin4 (of course)

of the extra 6 they SEEM to have:

pin6 to ground

pin5 connected

pin4 connected

pin3 connected

pin2 not connected

pin1 not connected

I broke the USB plug making sure everything was there (accidentally snapped 2 of the 6 pin part off.. so i need a new one)

if we connect the cable like this (using the pinout from the last pic as reference points):

pin

1 usb1 power

2 usb2 data +

3 usb3 data -

4 usb4 40.2k OHM to ground

5 usb5 ground

6 mhl1 blank

7 mhl2 blank

8 mhl3 wire

9 mhl4 wire

10 mhl5 wire

11 mhl6 ground

we may just be in business!

ordering a new cable as we speak.... since i broke my plug.

HDMI to RCA adapter

Hi all!

I'd like to know if there's a adapter to output audio and video through RCA in case I need.

A HDMI to RCA, or a microUSB to RCA adapter.

Thanks in advance
[Galaxy S III Accessories] mertzi:
Hello! You mean rca with red white AND yellow for video now right? You'd need a standard hdmi to rca converter but also still need an MHL adapter. I don't think anyone would manufacture a single adapter for that purpose.
[Galaxy S III Accessories] scarrmrcc:
Yep. adapting the digital signal from MHL to an analog signal needed for RCA is not cheap, and would be used by a small percentage of people. it doesn't make business sense. It would be like making an OTG cable that ends in an ipod plug, for those few people that want to mount their iphone/ipod onto their galaxy s3.
[Galaxy S III Accessories] kl25:
probably going to get flamed for this, but i don't know what to type in the search box of this thread to find my answer.

i found this USB hub on ebay

http://www.ebay.ca/itm/120970427074...X:IT&_trksid=p3984.m1438.l2649#ht_1550wt_1166

i THINK (in a very unsure manner...lol) one of those usb ports can supply power when the HUB is powered by the adapter that comes with it.

now, if i plug in the MHL adapter to the S3, and connect the microUSB port of the MHL adapter to the USB port of the HUB that supplies power, would that allow OTG to work? because now, the MHL adapter is powered and there are additional ports on the HUB to connect other USB devices.

someone probably thought of this already lol but it wouldn't hurt to ask......lol i hope.

thanks.
[Galaxy S III Accessories] coolbastard:
I think the same as well. There's no reason to release an adapter like this one to S3.

But maybe there's an older adapter which can output audio and video from a microUSB to RCA, from older devices that can be used in the S3. I don't know. I'm just looking for the cheapest option.

I'd also like to know which is the cheapest option if I have to buy an adapter from HDMI to RCA.

Tks
[Galaxy S III Accessories] scarrmrcc:
nope. scroll back through this very thread to find out why it wont work.
[Galaxy S III Accessories] cyberpine:
Are we still waiting on this???

Huge Market opportunity here.

Going to be killer when and if we get it. I too what hard connections industry standard HDMI and Full size USB Keyboard, Video and Mouse devices.
[Galaxy S III Accessories] tehstfu:
Of course since this is my first post, I can't submit links...

According to this: w w w .galaxymhl.com

Yes, the 11 pin connector supports both MHL and OTG. I can't see any other reason to adopt a connector with more pins. People are reporting that the OEM 11pin to HDMI (EPL 3FHU) does nothing until you plug in a power source, which isn't surprising. If this is the case, then this OTG cable w w w .tvc-mall.com/details/Micro-USB-Host-OTG-Cable-with-Micro-USB-Power-for-Samsung-i9100-i9300-i9220-i9250-MCH-382 posted a few pages back, in conjunction with a standard charger, should be all we need to run OTG from this little box.

If, however, this is all false and there really is only one ID pin that is supposed to discern charge/sync, dock, car, MHL or OTG modes, then I don't see how it can be possible to have both a short (required for OTG mode) and whatever resistance value MHL is responsible for.

Furthermore, we have observed that through the 11-5 pin adapter, the GS3 is able to use pin 4 to detect MHL mode. We have very little information on the OEM 11-DHMI device, with mostly vague descriptions of what does and doesn't work. Again, I can see no reason why Samsung would move to a device-specific plug type without actually adding some sort of feature or benefit. I'm going to buy the two items I described in the first paragraph and post my results.
[Galaxy S III Accessories] scarrmrcc:
your post is full of assumptions. and that is where you err.

there IS only on ID pin.

the MHL adapters made by samsung CANNOT do OTG (they are missing the data pins, and do not have the right resistor value)

MHL + OTG is possible with a 40.2kOHm resistor, and a full 11 pin device.. that is NOW available in germany.
[Galaxy S III Accessories] tehstfu:
Have you seen a Samsung pinout for the 11-pin receptacle? Or do you just magically know that?

You read one vague post in this thread saying there are no data pins, is that correct? Or do you actually have the cable and know that there are no data pins? The resistor value for OTG is a link from pin 4 to ground, meaning there isn't a resistor value.

Please link info about this German device.

Not sure where I'm assuming anything, just speculating on different things that have been posted, but of course your first reaction is to tell everyone they're wrong.

How about making an effort to actually discuss what might work instead of just posting asshole remarks to everyone?
[Galaxy S III Accessories] scarrmrcc:
dude, I AM that post. (and it was fully outlined in another thread, where I was doing teardowns, and figuring this whole thing out), I took them apart, I read the resistor values, I traced lines, through the whole MHL adapter, and it's circuit boards, and that the other thread (i fogoet which one it was) the 40.2K OHM value was found in the firmware. there were a few threads going around.. and even though the other that I speak of was the nitty gritty, this one kept coming back, with people assuming things.. and is the only current one.

I am not assuming, I am searching, researching, and tearing things apart to find out how it all works.

it isn't a german device, it is an official samsung device, but is only on the samsung german website as of now: the EDD-S20EWE

there is no need for any more research.. just a little patience.
[Galaxy S III Accessories] hyjkim:
Samsung now sells a device that allows for simultaneous MHL and OTG usage for the Galaxy Note 2. It is priced at $100. The S3 is not listed as compatible, but perhaps this would be a good place to start hacking.

http://www.samsung.com/us/mobile/cell-phones-accessories/EDD-S20JWEGSTA?
[Galaxy S III Accessories] scarrmrcc:
THAT is the link we have all been waiting for!

now the question is... buy the actual samsung for 100 bucks.. or wait and hope that a cheap knockoff will be as good, and cheaper.
[Galaxy S III Accessories] kl25:
damn it..i was excited to see this on the US site....then i realized.....

1) it's not going to fit with my trident case....

2) you'll be stuck in portrait mode using this?

damn it.
[Galaxy S III Accessories] kevinf28:
Thank you all for the information regarding MHL. You saved me a lot of money! I almost bought the official MHL adapter from samsung, thinking it would work w/ OTG. HAH!

I have ordered the monoprice 5to11, MHL to HDMI, and USB OTG adapters for less then $20 total. Seems like some hacking of the adapters plus 40.2k resistor should do the trick. Excited to hookup a USB-ethernet adapter while using HDMI !

There is a very interesting article from xda (showpost.php?p=25532839&postcount=2) which mentions various resistor values, what they do, and some of the cautions if you get it wrong!
[Galaxy S III Accessories] arghness:
See also here: http://xdaforums.com/showthread.php?t=1953061 where triffonovm got USB OTG and charging working at the same time, and provides further hints at how MHL might work (his cable currently causes an error to be logged relating to MHL, but it's not 11 pin)
[Galaxy S III Accessories] teshgnex:
That link is an awesome find! I have my 50% off Samsung code to use and I think this is it! Now the question is, despite the S3 not being listed as a compatible device, do I try it anyway?

I'd hate to have a brick on my hands...

What say the gurus? Worth a shot? I'd be willing to tear it down and build a schematic of course, again, I'd hate to have a useless dock.. I wonder if this is on eBay yet? Can anyone confirm if the Note II is 11pin MHL as well?

It seems they are all the same for both note 2 and galaxy s3 as they all have the same EDD-S20EWE

I've added a review too I think but it's in German
[Galaxy S III Accessories] kl25:
i used chrome to translate it and the guy said it didn't work with the s3...nothing except for charging works.
[Galaxy S III Accessories] XenomorphXx121:
There are some sites that advertise it for both the note 2 and galaxy s3, maybe it's because they have them on pre order.

Guess the best bet is to get one especially for the s3, I'll get one when they sell them on amazon and that way more of a chance at a refund if it doesn't work.

I did read on one of the links that it works with hdmi and can use a mouse with it and also a hard drive so that's good.

Guess have to wait until somebody actually buys one for the s3 and tests them out, they should be out by Christmas and hopefully cheaper.
[Galaxy S III Accessories] boundy:
The German Samsung site states the EDD-S20EWEGSTD is compatable with the GT-I9300MBDDBT Galaxy SIII, is this a standard Galaxy SIII or is it a regional model?
[Galaxy S III Accessories] nerys71:
I wonder if the new coming note 2 dock will work with the S3

http://www.mobilemag.com/2012/11/02...-your-note-2-into-a-desktop-computer-sort-of/
[Galaxy S III Accessories] megareyes:
The mhl for the s3 should work with the note as well from looking online many store are selling them as compatible for both
[Galaxy S III Accessories] scarrmrcc:
When the s3 first came out, MANY stores were selling the s2 MHL adapter saying it worked for both.. and some still are.
[Galaxy S III Accessories] teshgnex:
Well those are some mixed signals... =\

I wonder what to believe.. I know Samsung would accept returns, or for that matter I could take some loss and sell locally, not like I can find any Note2's for sale locally anyway...

I wonder if the 11pin mhl resistance trigger for the Note is the same for the T999 hdmi/otg trigger...

Any guesses?

I'll have to confess my ulterior motive to solve this - the motorola lapdock for the atrix/bionic series of phones has always intrigued me, the idea of a full screen laptop on the go is something I'd like to have.
[Galaxy S III Accessories] a32quaeler:
Well, the compatibility of the EDD-S20E with the S3 & N2 is advertised by the official German Samsung site and not only by some random shops. I don't know if there are differences between the European Dock and yours but i would expect the one named "EDD-S20EWEGSTD" to work with the S3.

Concerning the Lapdock, I use one for my RaspberryPi and I also have this application in mind for the S3+dock - but in the meantime you might want to have a look at an image I posted on the German amazon pages for the Lapdock.

www . amazon . de/gp/customer-media/product-gallery/B004ZB8SYU/ref=cm_ciu_pdp_images_all (I'm not allowed to post links)

I am using the allshare cast dongle to connect the S3 to (a slightly modified) Atrix Lapdock. The dongle is powered by the Lapdock (need the right HDMI-adapters for that) and the S3-USB-OTG port is free to connect the cable for the Lapdock-keyboard and touchpad (and the free USB-hub-ports for pendrives ...) to it. I am happier with this construction than I initially assumed. The only disadvantage over the dock is that the S3 is not charged. You may however charge it from the Lapdock USB-port if your not using the keyboard/touchpad OTG connection.
[Galaxy S III Accessories] teshgnex:
Thanks for the info a32!

that's great news! I was just about to order one when I realized the PAL vs NTSC issue I could possibly have... it's possible the US version has NTSC output (unless that's a standard rooted in the phone, not the tele), without breaking the dock apart, there's no way to tell if it's just a series of jumpers or signal running through an IC

unfortunately the US version is backordered, so I'm SOL for now. Will probably buy the official S3 11pin MHL cable to hack into mhl+otg

THAT is VERY cool. I figured it could be done, neat to know the allshare dongle can be powered with the lapdock, this may be the route i go (its just a matter of finding the hdmi-d female to hdmi-a male convertor.

My final intent at some point would be to have an MHL+OTG cable, compact enough (ie 1 foot or so, or less) to carry with the lapdock, to plug in on the go - bonus would be to leave the lapdock in OE configuration so I can dock my droid bionic or S3 at will)

in another thread (don't have the link handy just yet, I think it's a few pages back) it sounded like someone succesfully soldered an addtional resitance in the 11pin mhl to allow otg via the breakout micro-usb port, upon which one would have to add an additional resistance to allow for charging over otg
[Galaxy S III Accessories] a32quaeler:
I'm not sure if these analogue TV standards should bother you since the digital HDMI output of the dock may deliver 720p and/or 1080(p/i?) in 50Hz or 60Hz frame rates but modern HDMI displays should probably cope with both.... but I'm not an expert in that. Could be a reason for possible incompatibility of the docks offered here for both phones (EDD-S20EWEGSTD) and in the US for the Note2 only (EDD-S20JWEGSTA ???)... but it could also be differences in the firmware between N2/S3 and/or Germany/US which detects with the distinct resistor values on the MHL/USB port which dock/car/output/whatever... mode to switch to.

Nevertheless if you're good at soldering and find the right resistor values, you should be able to create your MHL-HDMI + -OTG adapter cable with charging capability to connect to the Lapdock which is surely more convenient than to carry around the bulky docks or allshare cast dongles. The only modification I made to the Atrix-Lapdock was turning the (male) micro-HDMI connector by 180degrees to have easier access and more space for the adapters. A tricky thing - especially when powering the dongle (or an HDMI-Adapter) via USB - is that the Atrix-Lapdock detects a device at its HDMI-port and starts to power the USB-hub only if successfully testing one pin (probably HDMI-CEC) for being connected to ground. Some HDMI-adaptors or cables omit these pins/cables and the Lapdock will not start when using them. However I don't want to hijack this thread into a Lapdock-modding one...
[Galaxy S III Accessories] teshgnex:
I think you may be right in the fact that pal/ntsc is dead beyond 480p transmission but I'm not certain yet (just did a bit of googling earlier but didn't find a definitive answer)

most definitely, lets move the lapdock mod discussion here (showthread.php?t=1762817) I'm going to start up that thread and keep adding my modification process to it to record the outcomes. I'll have to follow up more into how you got the allshare dongle to work. since the smart dock is sold out on samsung's US website, I'll probably buy the allshare in the meantime and try it out...

thanks for providing input! hope to share more ideas to get this idea to work!
[Galaxy S III Accessories] a32quaeler:
After performing some googling myself, I am pretty sure now that PAL/NTSC is not an issue but simply the fact that we have two different S3 hardware versions is causing a possible incompatibility of the docks:

The "international" Galaxy S3 "GT-I9300" sold over here in Germany AND all(?) the Note-2 versions share the same

SoC "Samsung Exynos 4 Quad" and the "ARM Mali-400 MP4" GPU

while the different US versions SGH-T999/SGH*/SCH* have the

"Qualcomm Snapdragon S4 MSM8960" SoC and a "Qualcomm Adreno 225" GPU.

Since these chipsets are to my knowledge also responsible for the HDMI capabilities, I assume that this is the reason why Samsung sells the EDD S20E over here for both phones while in the US it is only specified for the Note-2. It is only my personal speculation but it would explain a lot :(

Coming back to a bit more on-topic: this might affect the use of possible combined MHL/OTG adapters on US vs. international versions as well and result in different behavior when using the HDMI capabilities of the 11-pin MHL-port.
[Galaxy S III Accessories] kevinf28:
That is the international model. xdaforums.com/wiki/Samsung_Galaxy_S_III lists all the models and their complete specifications.
[Galaxy S III Accessories] boundy:
Do you think that Samsung Germany got the compatability wrong or that the info given to 3rd party resellers is incorrect?
[Galaxy S III Accessories] megareyes:
I recently purchased this mhl adapter from monoprice seems like good prices and usually buy only cables from them. 5pin to 11pin Micro USB Adapter for MHL Adapters and Samsung Galaxy SIII seems to be working great also needed the mhl regular adapter Micro USB to HDMI® MHL Adapter - Black looks like lots of items to connect including the hdmi cable but the good thing was that the single 5 to 11 adapter was very small so not bad overall.
[Galaxy S III Accessories] a32quaeler:
What I tried to say is that the German (="international") Galaxy S3 (GT-I9300) is perfectly compatible with the smart dock offered (also) for the Note-2 since they have the same hardware (not only the same 11-pin MHL). Hence Samsung/Germany sells it here for both phones.

Samsung/USA is also perfectly right with offering this smart dock ONLY for the Note-2 since the US-version(s) of the S3 (e.g. the SGH-T999...) have a different hardware than the Note-2 (specifically with respect to the HDMI/MHL capabilities)... thus the US-S3 is incompatible with the dock.

... that is however what I speculate from the available information.
[Galaxy S III Accessories] Ironman1965:
Been reading much about this. Trying to find out if it's possible.

One thing not considered so far is the problems that have been plaguing the latest JB updates is the flakiness of dock mode which still exists in the newest iteration of JB. Now I'm no dev, nor programmer nor guru. Just a simple power user.

I can't say if the smart dock is the same for the US and Germany, but sam.de seems to think that their version # EDD S20EWEGSTD is compatible with the I9300's.

A good point was made that the I9300 and Note 2 have virtually the same HW specs.

What I'm wondering is if the buggy dock mode in the latest JB's could be the reason the I9300 tested doesn't seem to work in the smart dock.

I have an IBolt car dock that was a completely useless device until enough research gave me the answer needed. Downgrading to XXDLH8 solved my dock problems. Every JB release post this ver has a broken dock mode.

What I have seen in trying to find out if this works is the testing needs to be more exhaustive and documented more thoroughly. There appears to be roughly 5 distinct HW versions of the S3, possibly 2 HW versions of the smart dock, and almost countless versions of the OS. That adds up to lots of possible combinations that may or may not work.

Each of these 3 things should be documented for testing.

I think the I9300 will work with the smart dock and that there is a problem in JB, but alas I don't have a smart dock to test my theories.

Request: If anybody out there has the German smart dock and I9300 and is willing to try a downgrade to XXDLH8 please give it a shot and let us know what happens. This is a valid test worth trying.
