Nexus 7 MHL - Nexus 7 Accessories

I have read a few threads etc saying there isn't enough pins etc for MHL.
Is this ebay person just trying to falsify to get purchases or did something change with MHL support that I haven't heard of.

Chinese seller in "Not telling the truth on eBay shocker"

Not enough pins on the pogo contacts. The micro USB housing is always capable of carrying MHL But there is no MHL display chip set in the N7

ok thanks

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:

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)

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..

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.

SlimPort - a new kind of magic? I Doubt it.

Hey all,
seeing all the threads about OTG and the difference to MHL, I thought I'd try to clear things up a bit:
Is this just another name for MHL?
No, it's not. MHL and SlimPort do the same, but in different ways. It's not the same and accessories are not compatible. You will need a new adapter, e.g.
Aren't we being 'appled' here?
Just a little, really. SlimPort does have several advantages, such as support for more than just HDMI and the freedom not to connect a power source, if you don't want to. Also it helps make the device as cheap as it is, because while MHL requires fees, SlimPort does not.
Does this device support USB OTG?
No, not yet. It should be possible though. Analogix (the makers of SlimPort) state their product will pass USB OTG signals to a host controller. Is there a host controller? Yes, there is! The N4's CPU includes one Figures it's a matter of support in the kernel, someone will likely get to this in the near future.
Sounds pretty impressive, huh? I'm afraid it isn't. While most manufacturers switched to a 11-pin design, SlimPort still uses 5-pin according to the whitepaper. Now, what does that mean? There's 3 data lines less, usual USB connections are not even possible, says the whitepaper. So it will most likely not be possible to use video output and OTG at the same time.
Most people will not care about this, but it will be a big deal for those - including me - who want to use it as a 'PC replacement'.
Correct me, if I'm wrong, but I did some thorough research and believe I should be right with my statements here.
Regards,

I'm disappointed with this switch to SlimPort.
1. I just want to get the display of my phone to the TV. So to me MHL and SlimPort do the same thing and it doesn't matter if they do it differently.
2. I feel "Apple'd" big time. Only one company makes these SlimPort adapters that I could find and they charge $30 for it. The MHL adapter I already own can't be used. Argh.
And I kept hearing about how I wouldn't need a power cable and that was suppose to be an advantage to SlimPort. But reading on their website, it sounds like the TV or monitor must support SlimPort too in order for the power over HDMI to work. Standard HDMI ports from the TV to the adapter will still need a separate power source.
I doubt SlimPort will catch on and I know I won't be spending $30 for an adapter that nothing else will probably ever use.
God, I need a freaking Miracast box that will work with my Nexus 4 in the worst way.
I think you pay the fees with the cable rather than possibly paying fees with the phone for a feature you may not want. I think this is why the cable costs more.
I could be wrong though and its just a company profitting because they are currently the only supplier.

I thought the micro usb sockets only had 5 pins anyway, so where the hell doe the 6 pins come from?

No, that was true for MHL, either the screen had to have a power output on the HDMI cable or you had to connect an external power source. SlimPort however makes this unneccessary, you CAN connect an external power source to charge your phone, but you don't have to.
If I already bought an MHL adapter, I would probably feel apple'd too, got you point, though

The standard is maintained by VESA and it's completely free. However, the HDMI standard still requires fees, which you pay with the cable. A display port adapter could be made way cheaper. But the latter is true, too. All these adapters could be made cheaper.

Anyone Selling DIY Pogo Dock Chargers?

Hi all,
I have a Nexus 7 2012 model that has a damaged micro USB port. I've search around and etc, Asus ain't making the pogo dock chargers for N7 2012 already. The current ones pricing in the market have been marked up way too high. Was wondering whether anyone could make one for sale? Or maybe kickstart one? I've PM-ed a few of those who actually posted pictures of their DIY pogo docks but they either never reply or haven't been online since way back.
