Serial Port and Serial Cable - Galaxy Tab 10.1 Android Development

So, since P1000 and P7510 have the same 30-pin connector.
And I have made hacked serial port connector for my 7 inch tab.
I wondered, maybe P7510 has serial port on 30-pin as well?
So I decided to find out by connecting my cable. What's the worst could happen? (blue smoke I guess?).
Anyway, yes, Virginia, there is serial port on P7510 and the output from the bootloader is:
http://pastie.org/2127655
I couldn't break in and talk to bootloader like on 7 inch tab. Maybe the bootloader can respond to some special key.

======== Param Data ========
size : 0x34
oemlock : unlock
sud : 0xff
secure : 0x3
fuse : 0x0
sbk : 0xffffffff 0xffffffff 0xffffffff 0xffffffff
debuglevel : 0x574f4c44
uartsel : 0x0
usbsel : 0x1

Maybe I'm overly optimistic, but would this actually spit out the SBK on a locked Tab? IIRC the SBK is only readable by the encryption engine. So why would anything bother to print it?
Anyway, ordered a spare connector to try this out on my locked Tab.

Can i use this to gain usb host? Or a similar config by altering the pin out?
If you could help that would be great. Instead of waiting for and buying the samsung adapter.
I believe its just rx to rx, td to td and id to gnd.

USB host is probably on other pins or it may be sharing regular USB or Serial port pins, with another pin used for detection.Unfortunately I do not have schematics for 10 inch tab. I found repair manual for 7 inch Tab a while ago and it describes some pins on 30 pin connector.
I think Samsung's USB dongle is a very simple device with bunch of wires and maybe some resistor inside, (isn't is supposed to be $20 only?).
I bet it is going to be reverse engineered in no time and there will be cheapo chinese knockoffs on eBay and DealExtreme shortly.

Got my cable together tonight, sort of.
I captured the boot output on my locked Tab, and funny enough it shows the Tab as not being OEM locked and with an SBK of all Fs. Of course that SBK doesn't actually work...
The only difference between the fuse section of the boot for locked and unlocked is that on locked "secure : 0x4" and on unlocked "secure : 0x3".
Ideas?
Here's the output of the boot.

just wondering if the lead for the samsung e900 will plug into the ameo and work to view on tv, link below.

I would assume that since the connector looks completely different from HTC one that it won't work.

The specs on the Athena say that this connector is an HTC proprietary port so the pin outs may not be the same. Do so at your own risk. Or get the pin outs for the cable you're wanting and send the specs to HTC support to see if they work?
EDIT: I know it may not be what you want but you could use the 4in1 cable currently available with the SVideo port and just use an SVideo to composite cable adapter?

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:
http://en.wikipedia.org/wiki/USB_On-The-Go
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 a 2 lane to VGA adpater :

http://www.nxp.com/#/pip/pip=[pip=PTN3392]|pp=[t=pip,i=PTN3392]
This is the Displayport convert chip we want to use:
http://www.paradetech.com/products/displayport-format-converters/displayport-to-hdmidvi-converter/
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

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)

Standard usb port adapter

Where is this at for the tab. Has anyone found it yet. I dont know if maybe froyo does not support the usb host mode needed or what. I saw that it was comming and yet cannot seem to find it. It was supposed to plug into the data port on the tab and give you the ability to attatch regular usb peripherals.
Any info is greatly appreciated

FWIW I saw a USB dock at Home Plus (Tesco for you guys in the UK) the other day for 29,000 KRW. Although I can't be sure, it appeared to be just a USB only dock but it looked like the HDMI dock recently reviewed on here.

you should try out the Elan Mobidapter, it's a micro SD to USB adapter with integrated USB Host. i'm using the Mobidapter often and im happy with it, but you can only use USB Storages with it. No keyboard support.
BTW: Android itself doesn't have or support an USB Host.

That's not entirely true. Most android builds don't have the necessary usb host support as part of the kernel, but there's nothing to prevent someone from compiling it or adding it in as a module. The Tab is/was supposed to do this OOTB, and based on the pinout information posted elsewhere, there is at least kernel support for determining if host mode should be enabled. With a modified iPod connector from Sparkfun I was able to get the Tab's AccessoryManager process (I think that's what it was called) to see a non-supported device plugged in (externally-powered USB hard drive enclosure), even if it couldn't enumerate it. It could be because I didn't connect the requisite +5V for downstream devices, or because there is no usb_storage module available. More testing needs to be done on this before we write it off completely. Hopefully Samsung will just release their solution(s) sooner than later.
That is what I wish they would do. But im afraid with the tab10.1 it may be put on the back burner

How did you modify the ipod connector? I have a few ipod/iphone cables lying around but they seem backwards compared to the sgt connector and difficult to modify.
I'm thinking about buying some sgt connectors or cables from china to play with.
Sent from my GT-P1000 using XDA App
Unfortunately I could not find a supplier of the "mirrored" iPod connectors that the SGT uses. I contacted many China-based component mfgs and none could point me in the right direction for that stupid dock connector. So I got the iPod one from SparkFun, used an xacto knife and small file to grind off the material on either side of the connector that keys it into the mating iPod connector. This allows you to invert it and plug it into the SGT, which then gives you access to all 30 pins. The cheap charging/sync cables that you can get from ebay and the likes only come with 5-7 pins connected, and the rest missing.

you know what sucks? I had a $100 haipad that had a microusb jack and came with a 6" adapter cable. guess what? you could plug in usb sticks, a usb mouse, or a usb keyboard. worked perfectly. mouse had a pointer, keyboard worked without a popup, it was all quite magical.
that was on a 2.1 resistive touchscreen chinese tablet.

Are there any local PC or cell phone repair facilities?
They could probably help you find the factory cable or point you towards someone who could.
Any where near a US military base?
Soldiers and saliors tend to have connections stateside.
Or you could just make one... It doesn't have to be pretty, it just has to work.
also from PH
Hi! I'm wondering if you ever did find one here in PH? My kindle Fire HD "7 is currently stuck in bootloop and I'm dying to fix it. Thanks!
Make or get one made it is easy
the connections are as follows
MicroUSB male Miniusb Male
1 --------- 1
2 ----- --- 2
3 ----------- 3
4 (connect to pin 1)
5 ------------- 4
Buy both connectors and just make above connections. or
take a thick USB cable cut one end and attach new microUSB connector as above. Do not scrap existing microUSB to bare the pins as some connectors have only 4 pins implemented.
I have found that most USB cales use standard color code 1(RED) 2(White) 3(Green) and 4 (Black) but it is better to check using Multimeter which wire is connected to which pin if you are tweaking readymade USB cables.
Its really confusing
im confused on what type of cable i need some are 3ft, 5ft or 79cm. Which one do i buy?????

Is anyone going to try this out?
Click to expand...
Click to collapse
I am. Have half the parts already and in the middle of my note II mobile office build. Was looking for something like this.
I'm curious if the resistor value is different per output or strictly used to tell the phone its on a smart dock? Then how best to handle multiple usb ports? On my setup power is railed and managed separately so just dealing with usb devices on the note at the same time would be the only unknown I am dealing with.
Edit:
Had another look. Looks like most of the voodoo is smartly placed on his proto board and an in line usb hub is doing the rest. Would be nice to have a map of the pinouts or spec via the i/o being used in the conversion. Should be difficult (famous last words).
EDIT:
After looking at the listed parts I realized there are some missing items to all of this....
First: the small red dongle that gets plugged in first is essentially a modified 11pin male to 11 pin female butt connection that has 2 pins wired from it and shunted to the usb port he has tapped to a pice of cardboard. I would guess somewhere in there a resister is placed for the usb i/o. That supposed to be a 11 pin to 5 pin conversion?
Second: everything past that little dongle is all plug and play. The hdmi adaptor and in line usb hub are separate components and are decided by the dongle.
So with a few dollars for the connectors a, substrate, some shrink wrap and solder we should have the magic dongle that makes it all happen.
This is all guessing based on what I can see on the video. Ordering what I need on ebay and going to give it a go. If success then I'll report with a how to. If someone beats me to it.... You suck lol. The challenge has been made so let's do this.

sorry those are for USB 3.0

Hopefully this may be of some help, I have also been trying to make one of these for the last few weeks.
So far, from purchasing this MHL - hdmi adapter, I have managed to map most of the pins, but am having difficulties getting USB OTG to work.
Charge, HDMI, and PC data connection work, but i still need to find the USB OTG pins for "smart dock" mode.
I assumed that this would work for USB OTG but it doesn't seem to work for me, it acts as USB Slave not Host (I.e. Connection to PC not HDD/Keyboard)
so far the pins i have identified:
(normal usb part)
Pin 1 - Vcc
Pin 2 - USB - (Slave)
Pin 3 - USB + (Slave)
Pin 4 - Sense (40.2K Ohm)
Pin 5 - Gnd
(extended USB Part)
Pin 6 - ? (Audio/USB host?)
Pin 7 - ? (Audio/USB host?)
Pin 8 - DP (MHL +)
Pin 9 - DN (MHL -)
Pin 10 - MHL ID (connected to ID Pin of MHL Adapter)
Pin 11 - Gnd
I will try and upload some images tomorrow, and a diagram of the plug.

Seems pin 4 and 5 would be used for resistance checking
40.2k for smart dock
365k for desktop dock
619k for car dock
Would be kinda cool and geeky just to throw a toggle and bam car dock or smart dock.
Edit: Just thinking. I wonder if the pin # 10 has to be in play with MHL mode and the 40.2k resistor on 4 and 5 to throw it in to smart dock. Hrmmm mm
Mine work without any connection with pin 10. So most likely it is nt used to understand any mode. But Samsung might set something with those pin in smart dock. If anyone dare to explore smart dock, then we can know about that

Just waiting on the last few parts. The plan is to reproduce your mod. Then experiment with the other resistor values and post results. Hate waiting lol
Seems no matter how much I checked I still got a 5pin converted to HDMI and not a 11pin to HDMI. Waiting on second order Bleh.
