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:
Dell Streak
Slacker G2

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)

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

Asus Confirmes Audio Dock

http://www.pocket-lint.com/news/46308/asus-nexus-7-audio-dock
Looks like it's going to be just an audio dock, connects through the pogo pins. Good since the single speaker would kinda suck.
no word on HDMI/MHL but i don't think those can work through the pogo pins anyway.

Perfect.

whaaaaat? this tab has pogo pins? cool
Perhaps with it having 4 pins it will allow for data to transfer with it (unlike the nexus with it only having 3 pins).

contrary to popular belief, the asus nexus 7 actually has TWO speakers/drivers. its shown in the first pic. theyre closer together compared to in the memo 370t, but there are two.
i havent seen how theyre hooked up, but theyre either in two channel mode or in single channel mode. chances are that theyre in single channel mode. even if it were in dual channel mode, theyre so close together it wouldnt even matter, it would sound like a nearfield setup.

No, unfortunately they screwed up. That's the cable included with the Nexus Q, there's still no HDMI capabilities for the Nexus 7.

What with there being FOUR pogo pins, I hope it is just a straight up USB type connection. That would make it pretty damn easy to make docks with USB connections for peripherals or whatever external storage may end up working with the device.
Can't wait to get my N7!

Where to buy this OTG adapter for SNote2 N7105?

Hello Members
Where can I buy this adapter (photo attached) other than ebay, in the UK.
Will it work correctly with my Note 2, as I'm going to use it to run an external USB DAC convertor, and need the extra USB power plug to power the phone and the DAC.
Failing that can, I get one made? Or make it myself from best quality audio grade USB cable and connectors?
If it's possible to make it, is there a specific wiring diagram for this OTG adapter + USB power plug that works for current Samsung smartphones?
Any help, or links to traders, and directions would be great.
Regards
Livio

Thanks for the links, but it's a OTG adapter with an extra USB male plug just for supplying 5 v power, reading a lot about making something up, but in short these modded adapter cables don't work with any certainty (something about not finding the nominal resistor value across pin (ID) 4 & (Ground) 5, which means either the phone goes to charge mode, but doesn't see the USB item that's been connected, or the reverse).
I thought the new Samsung Note 2 Smartdock might work, but it's been found to not see USB audio DAC's when there plugged in, unless someone knows different but I'm guessing the dock already takes the audio signal from the phones USB and feeds it to a 3.5 mm headphone socket in the unit.

Ebay have tons of them....
http://www.ebay.com.sg/itm/Micro-US...Accessories&hash=item20cdc2cc21#ht_3873wt_906

Thanks knight900, but I wanted to buy the item from anywhere other than ebay, the reason, well in the past whenever I made a purchase from this type of location/trader there was always fraud instigated on my PayPal account.
I might still consider buying from Ebay if other forum members have purchased the same item from a particular Ebay seller with no issues.

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.

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.

Correct i didn't even know what those 2 pins were for Audio or if they were for D+ & D- so thanks I have adjusted the picture accordingly. If you could check that out that would be great. After i get everything from Evil Bay this week i will do lots of pictures and full write up.
Thanks So excited to get started.

so are you saying that the POGO pins are THAT simple? and here i was building a dock for my N7!
if this is true, you rock man!

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.
Also when i get free time i will also create a Nexus 7 dock with built in speakers using the OEM POGO pins?

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.

USB C to USB A cable

Don't forget about these things, unless you happen to have a USB C connector on your computer already. The 5X does not come with this cable; it only comes with a USB C to USB C cable. The 6P does, however.
$13 at Google Store
Various prices on Amazon

Hi 0.0, I was looking at that same 4 pack earlier as well. Does anyone know if USB-C to USB-A cables (these specifically, or in general I guess) will allow for data transfer when connected to a PC or can they only be used for charging?
Edit: Nevermind, it says in the product description. Thanks, ordered a set.

mainly because i have a ton of regular cables, and also because soon the other ends are going to be type C. At that time, i will replace all my cables, but until then, these will do.

Not sure why, but it states in the description of those adapters that they are for Data Sync only, doesn't say anything about them working for charging. I hope that isn't the case, but just a heads up.

probably not rated for the current for quick charging

how about a type C male to type C female? does that exist??

For what it's worth, OnePlus finally have their cables up for sale after forever promising them lol. Android Police gave it stellar reviews stating it was of the better cables available when they did their review on them. They only range from $5 to $7 but you do have to pay shipping, still probably much better quality than the generic ones selling on Amazon.
I did order 3 of them, hopefully they are good. Wish they had some that were 6 ft. though.

Question for the community.
I rely on OTG a lot. I have a couple of Micro USB Male to USB A Female adaptors. Is there any reason that I couldn't plug a Type C Male to USB 2.0 Micro B Female adapter (like jadeddjay's item above) into the 5X, plug an existing Micro USB Male to USB A Female OTG cable into that, and then plug my standard cable into that? So:
5X <-- Type C Male to USB 2.0 Micro B Female adapter <-- Micro USB Male to USB A Female OTG <-- standard cable .
I guess it would it be safer to just get a new OTG cable with a Type C Male and USB A Female, like this one. But I'd rather get an adapter that can serve multiple functions as opposed to a new OTG cable that I will only use with one device.

Probably a dumb question, but...
I'm a little out of the tech game, and my knowledge isn't where it should be. That will probably make this a dumb question...
I am going to get a 5x, but have loads and loads of micro-usb peripherals; does anyone know if a micro-usb to type-c convertor exists? I've looked, but it's a pain to search for, as my search results always flip what i want around to type-c to micro-usb / similar.
Long story short; i'd rather not buy loads of new type-c cables, and instead would like a converter that I can plug into my existing kit, for me to then use with the type-c port on the 5x.
Does such a thing exist?
Cheers!

I'm been looking at cables since the phone was announced and I realize I've been spoiled by the cheap cables on monoprice. Hopefully they come down in price by the end of the year.
Is there a reason most A to c type are only one meter? .Best I've been able to find is 2 meter.
Would a USB extension cable work with a USB a to c?
I have a lot of charging equipment that is type a, trying to keep using it.

Well not everyone has an outlet within 3 feet of where they are sitting. For example, when I'm sitting in my living room, my closest outlet is behind my recliner, and I like to be able to use my phone while it charges, so a 6 ft cable is very handy.

6ft for sure is handy cause you don't want to sit against the wall.
Sounded in your original post though that you were trying to find some even longer than 6ft

Wait, why aren't people buying a micro-usb female to usb c male adapter to use existing micro usb cables and chargers?
