I want know how one would do the hdmi cable, will that be hard to reverse engineer?
[Galaxy Tab 10.1 Accessories] cleblanc92:
This dock is suppose to allow either the HDMI or the USB connector to plug in the back so that means it does pass all this through. This is going to be interesting....
[Galaxy Tab 10.1 Accessories] snaai8:
okay a few questions again..

Would it be hard to make a usb keyboard work on the tab (like cutting up the usb cable and replacing it with a 30pin dock connector?)?

And how much effort would it take to create a hdmi out? or a normal video out if possible..? Because I actually need an old video out port but on the samsung site is says that the video out represented is not compatible with the 10.1..

and where do you solder everything on? I've yet to find a picture of the 30pin connector which tells you where to solder..

Where would I solder in this image? http://shop.kineteka.com/images/thumbs/0000564.jpeg

Or should I just get a tab-out like this:

[Galaxy Tab 10.1 Accessories] ericlmccormick:
If you want to take a USB keyboard and make it work, the easiest thing for a beginner would be to get the tab breakout connector and then solder the wires as shown in the diagram. If you don't have a female connector, you can cut off the male connector from the keyboard and just match up the colors.

Only get the other connector if you have a way to ohm out the pins so you know what is what, have a good soldering iron with a fine tip, and also have a steady hand. I got my connectors in the mail last night and I can probably take a picture and specify the pin layout if you like.

As for the HDMI, I am not sure yet. Seems like either no one has an adapter or if they do, don't want to share what the insides look like. For the older tab, it had one pin for standard video, but HDMI has 19 pins so either a lot of pins on the 30pin connector get reassigned in some way, or there might be some type of chip that does the conversion. I don't know enough about HDMI to make a proper assessment at this point. I hope someone with an actual adapter will chime in soon.

I am really surprised at how much wasted space there is in there. Good news is that it gives me plenty of room to install a female USB A(host) and a female USB mini(slave) , hdmi out, a switch and the circuitry. Might even shove a hub and a card reader in there.

When I was poking around in the kernel code to figure out how USB host is turned on, I found that there is a car kit mode. I'm guessing this is what you want. You're on your own to find the magic resistor value though.
[Galaxy Tab 10.1 Accessories] Sholland91:
sounds like fun. As far as just audio out is concerned, do I need to do anything other than connect it to a 3.5mm female headphone jack (resistors?)

Everything looks great but what is the Universal Charging schematics for? What the heck is universal charging?
[Galaxy Tab 10.1 Accessories] Entropy512:
It's a small adapter that will cause the Tab to try and charge from anything that provides +5v to the power rails of the USB connector.

For example, if you connect the Tab to an iPad charger, it won't charge. If you connect the "universal charging" adapter in between, it will.

As to magic resistor values - I'll look into what chip they use to detect the resistors. Maybe we get lucky and they use the same FSA9280 as in the GalaxyS/Infuse phones. (Edit: not likely for that chip though.)
[Galaxy Tab 10.1 Accessories] 5thElement:
Thanks for the info.

Any schematics for HDMI?
[Galaxy Tab 10.1 Accessories] pokey9000:
From the pinout and kernel code, it seems the 10.1 spits out MHL and not HDMI, and requires a converter chip. This is what the box at the end of the Samsung dongle is for.

MHL was created so you don't need so many pins or a dedicated connector on a mobile device for HDMI. On some phones it shares the USB pins so a microUSB-to-HDMI adapter would be used with an MHL converter chip built-in to make the transition. On the Tab, it uses just a single high speed pair of pins for MHL instead of the 18 or so that are required for HDMI.
[Galaxy Tab 10.1 Accessories] xtkxhom3r:
i have a verizon micro usb charger with the extra usb port on top and it charges my tab with the original usb cable...im guessing its a 2A output maybe you should look into getting one of those chargers instead of going through the trouble of making your own cable.....

[Galaxy Tab 10.1 Accessories] ericlmccormick:
Your adapter probably won't put the unit in charge mode and might not provide as much power as he might want. Also still doesn't give him the audio out through the one cable.

Made my own dock

So in my spare time I am making my own dock. I am using these drawings and MHL chip I found real chip on the internet. My goal is usb power with another usb for storage using the USB host w/ power drawing. Also with a HDMI out and 3.5 Audio out.

Question about Universal Charging adapter.

I am not very clear about the universal connector?

I assume that the D+ and D- cables get cut on the male adapter side and the female side are connected to the two resisters, right?

Thanks
[Galaxy Tab 10.1 Accessories] pokey9000:
Are you doing your own PCB for this? MHL and HDMI are a pretty high speed buses so it'll need some real TLC to maintain signal integrity. You might be better off getting an MHL adapter for one of the phones that use it and hacking that up inside a case along with a hub and other goodies.

The good news is that MHL uses the same impedance cable as USB 2.0 so stripping the twisted pair out of a USB 2.0 cable should do for getting the signal there.
[Galaxy Tab 10.1 Accessories] Entropy512:
Correct. What it does is "hide" whatever D+ and D- are presented by the charger, so the Tab always sees what it wants to see as far as charging.

No published datasheet, not in stock at any distributor I can find - good luck getting that chip!

I agree... I'd be shocked if he's able to find the chip without cannibalizing it from a working adapter.
[Galaxy Tab 10.1 Accessories] kajolishot:
I picked up the USB adaptor. I wish there was a Male to Female cable that I could use to plug the USB adaptor into. Having a ridig adapter attached to the tablet while using the USB drive for video or audio is very awkward and feels dangerous.

Has someone already addressed this issue? :eek:
[Galaxy Tab 10.1 Accessories] pokey9000:
See the first post. It's fairly easy to make one yourself that uses a small connector + a USB jack at the end of a short cable.

[Galaxy Tab 10.1 Accessories] gonzule:
hey, great article! i cant wait for my galaxy tab to arrive to start making some of these cables. One question thoug, in my country the galaxy tab 10.1 is not yet officialy available, can i use the cables/connector from the galaxy 7 (P1000) on the 10.1? they might be cheaper for me to purchase locally than to order just the connector internationally. thanks!
[Galaxy Tab 10.1 Accessories] ericlmccormick:
Yes, the P1000 connector will work as long as the proper pins have been installed. If you look at a USB/charging cable, it may only have 5 or 6 of the 30 positions populated.
[Galaxy Tab 10.1 Accessories] ChoboNiNjA37:
I was actually messing around with the USB host connector that I made (I was trying to fit the resistors inside the connector, but I ended up screwing up the pins in the process), and I connected the resistors on the wrong pins by accident, but it forced the gtab into dock mode and brought up the clock.

I don't know if this was found out, but if anyone wants to attempt it, since I mangled my connector and I need to butcher one of my extra USB cables, I believe I used pin 14 and 15 instead of 13 and 15.

I don't recall reading about this anywhere, so I'm just posting my findings anyway. I think that pin 14 is the one I used, but I'm not sure, but I can confirm that I used the same amount of resistance for it at least.

So basically, the configuration I used was the same as USB host (1, 3, 4, 6), except I used 13 and 14. I don't know if the USB port is needed, though, but it did temporarily pop up when I plugged in a flashdrive, so that might be a good step for making a USB dock.

Sorry if this was already found out, I haven't read it anywhere else.

[Galaxy Tab 10.1 Accessories] Kings Lee:
thank you ericlmccormick! made a cable with your pinout.

has anyone able to connect a usb hdd to the tab? I used those Y-cable which supplies power to the hdd but still not able to use the hdd... any idea?
[Galaxy Tab 10.1 Accessories] Entropy512:
You need a powered hub or an HDD that has external power for this.

Also, if it's NTFS you need a custom kernel.
[Galaxy Tab 10.1 Accessories] Kings Lee:
Thank you for your quick reply. I just thought the Y-cable will supply enough juice for the hdd. Also found that it won't mount ext4 partitions, and it won't connect with my Galaxy S (High-Power USB device connected). Is my soldering skill that bad?

So far from my experience, only card readers and key memory sticks work.

Found on the internet somewhere a udev rule file will kinda help with the high power usb device, anyone knows anything about this?
[Galaxy Tab 10.1 Accessories] Entropy512:
Where would the second port of the Y cable get its juice?

Also, even if there is no overcurrent trip on the +5 rail, if a device tries to negotiate high power the tab may reject it.

A powered hub allows HDDs and other high power devices to work.

Surprised ext4 doesn't mount - it may be that the automounter doesn't handle ext4, but manual mounting should work.
[Galaxy Tab 10.1 Accessories] Kings Lee:
From a portable battery, like one of those from Zagg, that supply 1A.

I don't know understand this... :confused:

A hub is what I am trying to avoid, it greatly decrease the portability of the who setup...
[Galaxy Tab 10.1 Accessories] pokey9000:
Not a good idea. Those Y cables just short together the 5V from both plugs, assuming they come from different USB jacks on the same PC and so the same power supply. If you do this with the Tab and a USB battery pack, the battery will feed power into the Tab's USB host power supply when it turns off in sleep mode.
[Galaxy Tab 10.1 Accessories] Entropy512:
In addition to monitoring current on the +5v power supply line, when USB device that follows the standard wants to draw extra power, it has to ask the host for it. The mere act of requesting this power might cause the tab to disconnect a device, even if the device doesn't actually put load on the +5v rail.

What might work is with a custom cable that disconnects the +5v line from the tab, leaving only a common ground.

So:

Tab side - Ground, D+, D-

Power supply side - Ground, +5v

Device side - Ground (connected to both tab and power supply), D+ (tab only), D- (tab only), +5v (power supply only).

Of course, it could still fail - see limitation above.

Integrate USB Host /w Power in Galaxy Tab 7" Dockingstation= real multi-dock?!

Im interested in a "real multi-dock" for the Galaxy Tab 10.1v, because there is no -and probably will never be- a official dockingstation from samsung for this tab.

I read somewhere (dont find the source atm) that the dock from the galaxy tab 1 (7") is compatible with the galaxy tab 10.1 (and hopefully with the 10.1v in my case:) ).

This dock has

- 30 Pin Connector

- 3,5mm headphone jack

- HDMI C Type for Digital A/V Output

itself (search for "Samsung ECR-D980 Docking Station" on amazon).

It looks like the "7inch tab-hdmi-dock" handles hdmi-movies a lot better then the samsung-hdmi-cable (http://xdaforums.com/showthread.php?t=1226122&page=2)!

I think of 2-4 powered usb-ports integrated in this dock, so we have a real multimedia-dockingstation for our new 10.1 and 10.1v tabs:D

The "real stand" for the tablets will be a custom-made piece of wood, where the tab fits in well. The electronic parts come from the dock and the added usb-ports.

I would like to hear some opinions about my idea. Maybe some tipps?

I will start this project soon and post my experiences if someone want to hear them:p

Thx for your replies,

Galaxy Tab Resistor List or Resistor values

Hey guys.

I can't not be the only one some need Resistor values for the Galaxy Tab.

Like this for i9000 : http://xdaforums.com/showthread.php?t=820275

plz help me with the resistor list for the Galaxy Tab (P1000 & P7500)

I know i have to use Pin 13 (USB ID) + GND Pin 15.

But the list with resistor values will be so ****in nice.

************************************************

Resistor List by Smokers' Choice! (me):

20K ohm - USB Host (USB OTG)

7.25K ohm - Car Dock (I found it inside a orginal Samsung ECS-V980 car dock, without sound jack, only power)

12K ohm - Video Out (only P1000)

4,3K ohm - HDMI dock only if plug audio out cable

************************************************

There will be more, when I found several, that I am 120% sure works.

But help me to complete the Galaxy Tab Resistor list.

Usb charging

Hi nice for your work but looking at pins and what you put on them something get wrong.

1. First USB chargind w/o modification work but only low power. 100-500mA

2. To get only usb charging w/o data line just shortcut D+ wiht D- and if your power supply can drain 1800mA max. (Samsung made 2000mA for safety)

3. Car adapter use instead of 20K an 7,25k and the matrix (10k and 33k)to pull up to 3.3v the D+ line and this tell to tab can drain more power than 500mA.

Up side Down.

More power drain faster charge battery get hot (lose fast his ability to keep energy Li-Io have a problem can chargit as may time you want but when you get her hot you lose it dont let chargit over the night)

4. The pic with universal charger (3th is wrong) about the pins connected

1 (Gnd) 3(D+) 4(D-) 7 and 8 (Vcc 5V) other is ok.

In your pic the Gnd go to ping 3 of SGT which is wrong.

5. I have some reservation about HOST mode and extra power.

If SGT rize power to 5V on ping 6 and you give power on 7,8 his regulator dont work (same chip is used to regulate power from 5V to battery charger and change the way make him to make from battey ~4,25 to 5V)

I attach the pic with how it used the chip of charging and OnToGo

I my get wrong on something but pleas fix me.

Ok here are some pictures of the inside. Made with my galaxy s so no flash..

When you open the dock you see the iron plate to make it heavy. and a flatcable and a circuit board.

When you remove the iron plate you see there is a resistor 4,3K on the circuit board that goes to your line out (headphones) jack.

Pin 1 = 30 Shield Connector

Pin 2 = 28

Pin 3 = 27

Pin 4 = 13

pin 5 = 19

pin 6 = 18

pin 7 = 17

pin 8 = 6

pin 9 = 7

pin 10 =3

pin 11 =4

pin 12 = 1+2

[Galaxy Tab 10.1 Accessories] Bxsteez:
This is basically what I'm trying to do :) How are you dealing with the serial lines for the USB? Are you just branching off the input 30pin connector or did you cut those traces and are just using the USB port?

This is what i was thinking of doing. I was going to create a pwb with this present. Although i think i'm going to switch the ss relay with a fet circuit
[Galaxy Tab 10.1 Accessories] climmax:
I was thinking of the USB host + charging sheme. and add a switch so i can switch between 7.25 k ohm (Cardock) and maybe another value for deskdock mode so i can use host + charging + Line out. And use the 30 pins female connector to charge in some what way. The syncing isnt really nessesary because in the car i dont have to sync.

I dont know if its possible. but i am going to cut the datalines and let it go directly to the female usb host connector.

5v and ground just solder it onto the connector without cutting the lines.

I just have to figure out someway when put into cardock mode / deskdock mode the line out will work and also the usb host. Or need to have another value of resistor...

This is the i9000 resistor list. when put in deskdock mode the line out works. so the desk dock mode is the 4.3k? But im not sure... have to test it all when i get my 20k resistor.

Hi All, this is my first post here...

I experienced the same thing here.. So what I did was to connect the pin 15, 16, 30 GND in Male USB to Pin 1 (GND in Female USB) and D+ and D- in Male USB to D+ and D- in Female USB, but Pin 7 & 8 to 5v in Male USB. By doing so I can only use USB hub or charging at once, can use them both at once...

Pls find attached the pic of what I did..

There are 2 female usb in the pic, one for hub and one for charging.. combine the charging port with inline charging cable I made then I'm good to charge with any 5v power source...

based on what I tried, seems that galaxy tab will only enter the charging mode if pin 3 & 4 are shorted.. otherwise it'll enter MTP mode... any suggestion on this? Thank you...

Looks like you can't charge and OTG host at the same time.

From this post it looks like our friends in China have made a charge/host cable by allowing one to switch between the two modes.

Looks like you can charge and have data at the same time - but you need to be using Pershoot's Kernel to enable it.
