Third party Samsung-"PDMI" accessories

Is any third party accessories announced that utilizes the port on the Galaxy Tab?
(It is similar to PDMI, but not compatible, right?)
I would love to see an adapter to connect usb-devices such as usb memory sticks and digital cameras for backup as well as a hdmi output cable.

i start workin again next week after 2 years of school... goodbye lovely time....
will be coding machines and wanted to make a selfmade hdmi dock for the tab.
...as some excersie after 2 years...
but nobody in here is able to post the pin assignment of his dock or. tv cable.... thanks to the community!!!

Hi
I am also trying to find out more on this matter to make my own "real" hdmi cable for the Tab or experiment with other fun features as sub stick adapter...
The port seems to be a fully PDMI port, don't know if USB 3.0 signaling is there though.
The Dell Streak also use PDMI connector.
PDMI info:
http://en.wikipedia.org/wiki/PDMI
USB on tge go OTG:

Displayport info:
http://en.wikipedia.org/wiki/DisplayPort
http://www.displayport.org/cms/sites/default/files/downloads/DisplayPort_Technical_Overview.pdf
The PDMI connector features a 2 lane Displayport adapter.
To convert from this adapter You would need a chip that can convert dual lane Displayport to HDMI as most readily adapters use 4 lane Displayport AC level conversions as this chip:'

This is the Displayport convert chip we want to use:

This is just a quick summary.
The first thing we need is to find a suppier of PDMI contacs instead of ripping apart expensive charger cables to test with.
Other devices that uses PDMI connector:

thanks to zab... i finally get a useable tab... all my questions have been anwered :0)
now lets start workin.... i m going to make a stand for mobile and outdoor use.
there are some cheap solar battery extenders out now...
i think video without hdmi should do its job.... look at those tiny mini beamers :0) i own one :0)
ok... now lets reactivate my braincells... hits from the.... .... ....
edit: after a short look at my samsung usb cable..... i have to say its not pdmi standard. :0(
shame on samsung! there are 7 pins used in my cable... ok only 23 left... grrrr

What is the pinout You have measured then?
And does anyone have the videocable so they can measure the pinout on it?
I don't wanna sacrifise my cable until I have a spare one. I've already lost it once and the battery lasts for 3 days. After that it was a long wait until I found it again as I haven't found any spare cable here in Norway yet in the stores.

Belkin have a hdmi cable you can order.
Don't now exactly how it looks, hope it's just transforms the pdmi to a hdmi port where you can mount a standard hdmi cable. But it almost seems like item will be a mini hdmi import.
Have ordered one, hope i will have it ibm some days

thanks, i'm going to take a look at this.
edit: nooooooooo!!! you bought an mini hdmi to hdmi cable.... its for the dock... oh man.
there is no pdmi. not in your cable and not in the tab too.
...i was searching in some other forums last night.
it looks like the dell streak has got the only real pdmi pin assignment.
when i look at my tab usb cable the pins that are used are:
3,4 then 7,8 + 15,16 and finally... pin 30 !? ...perhaps they where drunken when doin this...
comparing to pdmi-wiki and dells it looks like samsung only used the size (you can plug it in the dell tablet) but fully messed around the assignment so most of users have to buy a piece of sh... for 50 bucks.... wow!!!
.... ... i bought fruid-salad but i only taste apples.... .... thanksung!

It's NOT a PDMI connector, Samsung have altered it so it's mechanically compatible, but not electrically.
We don't have any specs on the actual pinouts of the Tab connector yet as far as I'm aware.

me dont buy pdmi accessoire :0)

Thanks for looking this up,
luckily i haven't got the cable yet. So will remove my order and buy the hdmi dock and a hdmi mini to hdmi cable.
If i have now the length of belkins cable i have bought it, but now i don't now that so will find a other cable

Charge and audio out combo cable?

Any chance we will see a combo cable that would allow charging via usb/and also provide audio out? Id like to run a charging cable behind the dashboard of my car for docking in a cradle, and also have audio out for the auxiliary input to the headunit without having to run a second wire.
Not that running a second wire would be much of a hassle, but would prefer a cleaner look when docked and one less wire when not in the dock
I wish Samsung had put some thought into their car dock. Id be happy to buy the official dock if they hadn't dropped the ball on this one.

It was easy to convert the car dock so it has audio as well.
If You seek on my posts You will find a how to.

Sorry to resurrect an old thread, but I couldn't find the howto. I would like to mod the OWM car dock to allow audio output, and I'd appreciate any help in such direction.

i have this one
but u can find even cheaper on that site

hey, quick question: does it work only for video? or power point as well? thank you

it does
its a good alternative to the dock even if its not HD

Do I get my music through this cable? Or does it work with combined video audio files only?

i searched through a ton of your posts and didn't see anything besides the pinout. my question is how do you take apart the plug to get to the connector, and are all the pins available to solder to?

http://forum.xda-developers.com/showthread.php?p=9985704#post9985704
well here is the post where the gentleman posts to replace a resistor to get it to output audio to the dock. the only question left is how to take the thing apart, whether it comes apart nicely or i have to break out the dremel...

Not sure if you need the same as I do, but my idea was also to have a USB charging plug and an audio-out jack. It wasn't easy, but I found this:

I got one off Amazon, some off brand but it gives a terrible hum in the audio and the tab doesn't see it as a dock.....still looking for a solution

Streak adapter for iFail Accessories...

Since the cable idea didn't work out, I decided to work on a couple of other items for the Streak.
I have spec'd out an adapter for us, so that we could use the immensely huge iFail (iphone/ipod/ipad) accessory market. Things like Speaker/radio docks, et al.
We would plug our usb end into the adapter, and the other end of the adapter is fitted with a 30 pin apple female connector. I am also adding micro/mini usb..so that the adapter can be used with more devices Please tell me what you think about the cord length.
PLEASE NOTE: In this picture, the iphone end is "male"..it would be FEMALE for us!!

How about no cable but a jack type affair on the adapter so you could plug a cable into the adapter? or a short tail with plug for cable?

That is what I really wanted..... but it is very difficult for the factory to do, and would not be cost effective....like 5x the price (without even knowing the price yet...lol)

How many pins do you plan on passing though?
USB/Power/Line out?
I'd be interested in an adapter too.
Best would be a small Female Dock <-> Male PDMI block (but as you said it might be unreasonably expensive)
How about a Female Dock <- short cable -> Male PDMI cable? Is that the plan?
Have you inquired about a simple Male PDMI <-> micro (or mini, i forget which is which) block? Along the lines of this but with PDMI/USB. Or also as a short cable of it's not reasonable price?
If you can only do a short cord + 2 connectors like the picture, can you do just like the picture of about ~1 inch?
I'm definitely interested in seeing how this plays out

This current plan (still working on actual dock too, separately) is:
Female iFail 30 pin <--cable --> Female Standard USB + Female Mini USB + Female Micro USB (so it appeals to more devices)
Planning on Charging/Sync/Audio
Does that answer it?

Sounds good to me. Count me in.

May I suggest a Male PDMI -> Female USB Block/Cable for connecting USB accessories to the Streak? USB Keyboards work by default, the block would just need a short wire to connect pins 2 and 4 of the PDMI together (I believe) to activate USB Host mode.

I think it already exists. Isn't this what you are looking for: cablejive.com/products/Universal-Dock-Converter.html

still would be better for an adapter that plugged into the streak and had female micro/mini.
Something low profile that could potentially be left plugged in and left in place.
Start with a naked streak and if popular make ones for a otterbox defender/commuter, etc

This is why the internet is so important...lol Thanks for finding this "unicorn"
I searched and searched and searched but could not find it, so I decided to possibly have it made. This is very similar to what I was thinking. Differrences would be the addition of mini & micro usb female connectors with my idea. Also hoping to make it sleeker with just one cord...and for a much better price.
In addition to that, this particular site says:

I don't see how that can work.
You need the 30-pin PDMI connector on one end, and the Apple connector on the other. Here's the Streak's pinout http://linuxslate.com/#Dell_Streak_PDMI_Pinout and here's the Apple pinout http://www.allpinouts.org/index.php/Apple_iPod,_iPad_and_iPhone_dock
If it's simply going to connect USB to the Apple connector, then it will only be able to pass USB's 4 pins of data and power - there'll be no video or audio output. What's more, there are already adaptors on the market for USB to Apple, like the one already mentioned http://www.cablejive.com/products/Universal-Dock-Converter.html

Both PDMI and apple dock connectors support line out for audio, only thing it wouldnt take advantage of is video out and USB-OTG
At least what i was interested in was a PDMI <-> Dock directly

This is an intriguing project. I have a question about accessory compatibility.
I've been desperately trying to work out an external, powered mic set up for the Streak. I've established that the headphone jack, like iProducts, doesn't supply phantom power. iProducts got around this by using their dataport to power attached microphones. So in theory, this solution could connect to an iMic and supply the same power.
Here's the q: Is just having a powered mic attached via dataport (through the adapter cable) enough? Or work a supporting app have to be written to tell the device that there's a mic there and also handle the supporting software to make it work?

PDMI only supplies line out from what we know, nor does it have power out.
Even if it could do both, wouldnt it drain the battery pretty quickly?

All I care for is a line out and the charging. Who gives a damn for the video and other stuff. I care more for the pure acoustic bliss.

I would like it to just lie and say its apple so my car play music from it.. using then ipod interface..

Best OTG?

Can anyone recommend a decent USB OTG that hangs down the side of the nexus 10 rather than sticks out?
Preferably one they've proven to work with an N10.
I appear to have lost my Samsung one I was hoping to use.
Thank you.
Swype'd at pace from my Galaxy S2

I have this one
http://www.amazon.com/gp/product/B005GI2VMG/ref=oh_details_o01_s00_i00
Works perfectly with my thumb drives and external hdd. Not only does it work, but the price was unbeatable.
Don't buy one of those $10+ cables as it does the same exact thing as this one.
I might add, you could possibly look into getting one that can charge the device at the same time it's using an external storage device. Unless you're okay with it.
Stickmount works with root on my devices
Nexus Media Importer works without root on my devices
GNex and N10.
Hope this helps!

Confirmed that my OTG cable works.

I bought both of these. Both connect with the larger portion of the USB connector towards the screen so they hang down the side of the tablet:
SANOXY Micro USB Host Mode OTG Cable - The connector for this one was flipped from the picture and hangs down the side of my N10.
eForCity Micro USB OTG to USB 2.0 Adapter - This one came just like it was pictured.
Both came from Hong Kong which took about 2 weeks in the mail however they cost just around $1.00 each and with free shipping not much to lose.
I use mine with a elago Mobile Nano II USB 2.0 microSDHC Flash Memory Card Reader and a 32GB card (my 64GB is in my S3). With the adapter in the OTG cable it barely hangs out the bottom and makes it very compact.

I have 2 kinds of OTG cables here, both working perfectly fine with my Galaxy Nexus. However on Nexus 10 when I connect a USB device to the OTG (or connect the OTG cable with a USB device already plugged in) the tablet turns off completly and I have to remove the OTG to be able to start it again.

OK -- Sorry to resurrect a glue'd horse, but does anyone have a link for one that ALWAYS ships the correctly sized (read not too long) OTG adapter? I've already ordered two of the OTG adapters through Amazon but they BOTH have too long of a connector and it basically sits loose in any device. Very lame.

Just an FYI I e-mailed Juiced Systems to see if this would work with the Nexus 10. Their response is below:
The adapter should work with 4 out of the 5 functions for the Nexus 10(MHL maybe not). I have yet to test it out personally. This is something we will test soon and will post online. The nexus 10 does have an HDMI mini port built into it already. If MHL doesn't work that is because google did not think it was necessary to make it MHL capable when it has an HDMI mini port. The Nexus 7 is not MHL capable either, not sure why they chose to do that. I will keep you posted once the nexus 10 testing comes back.
Thank you

Can you still access the headphone jack with this OTG cable?

Can anyone tell me how an OTG cable can be better than another except of the price/length/design ??
Isn't that micro USB to USB cable just a normal cable connecting 5 pins which are either in a bigger or a smaller plug?
Why should such a cable not work (except of the situation that the cable is damaged)?

I watched a video on how to make your own, if it was correct, they stated that one pin was unused and when it is connected to chassis ground tells the device to go into OTG mode.

So this OTG cable is not just connecting each pin? It's not just an adapter?
Okay then, good to know, thank you

If you took a razor knife to the strain relief part it would work, as it is you can stress it out of the way enough to fit a headphone jack but it puts a bit too much pressure on the USB port for my liking try it they're cheap!

i see most are using ones with a cable, is there an issue with ones like these?

I got 2 of this, works pretty well and sits close to the side of the tablet.
Only 2 issues, the connector itself is long so it's a little loose and it will block the earphone jack.

NEXUS 7 Car install Diagram

Hi All,
If this has been done before please ignore.
I have been doing a fair bit of research on the NEXUS 7 as a car head deck but no diagram to go off.
Can you please advise if the Diagram below is accurate or if i need to amend certain areas to make it work. The NEXUS 7 will be slide in slide out.

Subscribed to see what others have to say. I am hoping to skip the head unit and sub and go right from the N7 to the amp. My worry is getting clean audio out of the N7 while it gets power.
I have a ground issue somewhere currently where if I am charging a device and have it plugged into the aux port of my head unit, I get tons of static and noise.
Sent from my SCH-I605 using Tapatalk 2

Only comment I'd make is that if you're going to use the POGO pins to power it why not grab the audio from there also? Seems safer to use a non intrusive (without a plug going into the Nexus) method over sticking in the headphone jack.
Sent from my Nexus 7 using Tapatalk 2

He probably didn't know he can do that. You can also use a USB dac and get audio that way. Probably much cleaner and it will also fix his ground loop issues.
I owned a Galaxy Tab before the N7 and it was MUCH WORSE at adding noise to the headphone output. The N7 is much much better at isolating that ground.

Unless your drawing is just an example, your speaker wiring needs to be changed so you're not daisy chaining the signal. Run 'home runs' to each driver.
Sent from my Nexus 7 using xda premium

Also there's no need as in actually you can't do that have a DAC on the audio lines. They are analog L+ and R+ with the ground being common between power-, L- and R-. Look for the POGO thread over in the accessories subforum along with one on a homemade dock for more info. There is no USB on the POGO pins.

Close, but not there yet. The 2 middle POGO pins are Audio +/-, and won't connect to a DAC as it's already an analog output. You can connect the DAC via USB though, and get the highest quality audio possible out of the N7.
HOWEVER: if you want to charge AND use OTG (DAC and external storage will connect via OTG), then you'll need a kernel which will support that. Running power through the POGO pins also requires a special kernel. This is the only one I know of:
http://rootzwiki.com/topic/37755-timurs-kernel-usb-host-power-management-usb-audio/
The fixed installation is the best choice for car applications.
Alternatively you can use audio out and charge through the POGO, and use a kernel like faux123's kernel to charge and have USB OTG (but won't work with a USB DAC), though there are limitations to this setup.
EDIT: I've attached a diagram of my current car setup.

Thank you for your diagram you've definately got alot going on in your car Looks good.
This is what i have bought.
Nexus 7
FiiO E10 USB DAC
Clarion EQ746
3ft male to female USB connection
3.1A Dual USB Charger
Micro USB female
AUX to RCA ( Not sure what ill be using this for now )
Pogo Pins
Magnets ( Not sure if I'll use these yet )
Will the above work? I've read way to many forums on this subject and no one is actually clear.
If i cut up and strip back the rubber around a Male USB can i use this as my POGO pins connector to the USB DAC + Kernel suggested?
*phillip1953* It is just a quick drawing and i can assure you this won't happen when installing.
Everyones input is greatly appreciated Thank you.

I think I have a working diagram to go off. On a positive note my NEXUS 7 arrived today Wohoo.

You really need to read the whole thread that MetalMan posted above. It will show you what you're doing wrong, and give you more to think about.
EDIT:
I really wouldn't charge off the pogo pins if I were you. Get a USB OTG + Charging Y Cable and just plug/unplug that as needed.
