wow some really nice looking extras, im glad they decided to add them this time around, i believe the desktop dock shown also has an AUX output in the back to play music on large speakers, however if this is true, i dont see an AUX input on the dock, so it must stream the audio thru microusb, and then out through AUX, very interesting, but seems likely, since the implementation of MHL!
Nice find, thanks.
From what I've heard it sounds like Samsung are not supplying the MHL or USB OTG adapters in the retail box, which is a great shame and rather poor really. Can't say I'm surprised, because Samsung have tended to follow this practice with their previous flagships also.
^ Correct, MHL cable listed on Clove website as an accessory...
Let me ask this. This is an MHL port, meaning I can plug in a regular mini HDMI or mini USB(or micro, if that's what it is) like normal? Or do I need a converter cable?
On the SGS II, MHL runs over the physical microUSB interface. It can output straight to 1080p HDMI w/ audio (and charge at the same time) as well as use it as a USB host OTG device. You'll probably have to use the adapter cable to get HDMI working. If you want to charge over MHL, you'll also need an MHL-compliant TV but you can still charge normally using another cable while simultaneously outputting video.
So yes, chances are you do need some sort of adapter cable, at the very least microUSB to HDMI.
For outputting HDMI you need an MHL cable, thats all. If you want to charge and output at the same time you need a dongle (soon TVs that support charging over MHL will come out, and then the cable will handle both, in addition to letting the TV remote control the playback device).
This is my first post with links and info and stuff so please don't mind the bad formatting or other errors.
I bought a docking station a bit back and tore it down; I'm not very impressed but I'm sure we can make something of it.

As you can see on this unit there isn't any HDMI however the board was made for it. Also of note is the HDMI pins on the ribbon cable.
I've checked and the nuvoTon (W78E052DFG) is an 8052 with 8KB flash and 256 bytes ram.
The audio portion seems to have a filter set on it however I don't believe it's amplified.
I have not been able to determine if there is or isn't USB on the ribbon cable or connector though there's no sign of it on the board.
Another point is I've switched to a custom rom and it no longer detects the dock. I noticed before switching that there is a service that watches for the dock and I'm guessing sends a signal to android to start the media app on dock. Virtuous XooM does not in any way detect connection.
Communication with the 8052 is through serial and the kernel source shows info about it. I haven't been able to find any reference to USB. if USB is present I'd expect it to be the pair near pin 30.

------- New info: (copied from later post)
This is the dock pinout as seen by the tablet (other devices may have different pins connected)
1-10 no connection
11 - unknown - traced to Q9 near IR connector on dock but unable to find past there (2v from tablet)
12 no connection
13 - audio connect of some sort - appears to be connected to left channel (after capacitor) through a 1k resistor
14 - Right audio - decoupled with 100uF
15 - Left audio - decoupled with 100uF like right channel
16 - Audio ground - not connected to main ground
17 no connection
18-20 +12V
21-30 HDMI - NO signals connected except GND at 21,24,27,30
31 - unknown - 3.3v from tablet
32 - TXD pin on 8052 through a level converter
33 - RXD pin on 8052 through a level converter
34 - unknown - 0v - 3.3v when dock unpowered but tablet connected so this may be a dock detection
35 - connected to 33 on tablet side
36 - connected to 32 on tablet side
37-40 no connection
These are all assumptions based on zebra cable layout so are quite probably wrong. They are also numbered based on the ribbon cable and I haven't made a conversion between ribbon cable and connector.
A voltage readings were done with an uncalibrated DMM on an oscilloscope (which seems to be .2v off or more). If i mark "from tablet" it's because it's not live when tablet not present and live even if power is disconnected from base.
1 case ground 0v
2-7 serial port(0v across)
8-20 HDMI
21unknown 3.3v from tablet
22 unknown 2v from tablet
23 unknown 2v from tablet
24-25 audio - audio even when nothing plugged in 0v
26 audio ground 0v
27 unknown 2v from tablet
28 unknown 0v (3.3v when dock unpowered but tablet docked)
30-35 12.0V
37 unknown 0v
38-40 gnd
Audio pins are correct but I can't tell which channel is which without finding a mp3 with audio only on one side. I would also trust the HDMI pins as ballanced pairs with shield between running directly to the HDMI portion of the board does seem rather proving.
None of the pins really look like USB as they should remain at 0v until a device is plugged in. I'll test connecting a 1500 ohm resister to 3.3v while monitoring the pin under test and see if I can find a USB connection attempt that way. If that doesn't work, finding pins with 15k ohm to GND would also indicate USB and I can try connecting a device to those.
Just recieved mine today from Amazon (they went on sale, so I figured I'd bite). No HDMI is disappointing, but not a dealbreaker for me.
Oddly enough, my biggest complaint is that it doesn't come with it's own power cable. I was hoping to leave the dock hooked up at home, and be able to pack the (INCREDIBLY SHORT) A500 power adapter in my bag for when I go out. Looks like it's back to eBay for another...
Excuse my off-topic mini rant. The teardown is appreciated. Curious if you ever did find anything with the USB pins.
I've read there are 2 versions of this docking station, one with HDMI and another without. It seems a lot of sellers are advertising the HDMI version but when people receive it, they get the non-HDMI version instead. Seems it's a hit or miss if you buy it online, probably safer to buy it from a brick & motar store so you can verify which version you're actually getting.
Sorry for off-topic too, just wanted to warn those that are thinking of getting this docking station
Nice tear-down btw.
Any idea what the part number for the connector itself is ? I am interested in a custom dock setup and all I am concerned about its power, however I need to find the mating connector to integrate into it.
Any info is appreciated!
Jeff
Quality of the photo surprised me !
So, any more info on this? I am putting an a100 in my dash, and I would like to use the dock connector at some point. For now I'll just run the power and audio through their ports I guess, but I would like to simplify the install at some point.
If these things suck so much, hopefully the price will drop soon, and I'll feel comfortable buying one to take apart for experimenting myself.
Thanks!

There aren't any identifiable markings however I think I found the right connector by checking some of the vendors who make 'em. I'm almost positive the connector is: JAE - DD2 Series
This means that there's also a cable variant of the dock side connector, cool eh?
I have not measured the connector to see if the dimensions are correct but the pitch, count, offset appearance and overall appearance are perfect matches. Even the slits cut into the top of the tablet-side connector match what's in the drawings. Still not a guarantee, but good enough for me to buy a couple to see if they match.
Here are the digikey parts:
PCB connector - $7.67 in singles
Cable connector - $10.67 in singles

Perfect information. It seems that the 002 (HDMI) version has not been released in the US. It is not available on Acer's US site, nor do any of the US based online or B&M stores have it.
I'm definitely eager to see how this turns out. I'd love to know what each of the pins definitely is.
One assumes that the HDMI version is only required for the A100 series as the A500 already has full HDMI built in. Would the HDMI circuitry even work with an A500 in the dock? In fact, can you actually use the docks at all mismatched to the Iconia for which they were intended?

I wouldn't assume that at all... docs are designed to be left in place... so the purpose for the hdmi on the doc is so that you can keep it connected to your display all the time and not have to worry about plugging in the cable and the power... etc. where the doc satisfies both those needs. And I believe.. the hdmi doc for the a500 was available some time before the a100 was even released. (chk)

What's your confidence that pin 30-35 is actually 12V? Is is obvious (direct connection to the power port on the docking station)?
I will be buying one of those connectors (making a car dock) and want to be sure I won't be frying anything.
I will confirm if the connector fits and works in the A500 once I get the connector.

It's direct connectivity between +12v on the power jack and pins 30-35 on the zebra cable. These are not the same numbers on the connector itself.
If you look on SJ100278.pdf (digikey has link to drawing) the pin numbers are there. Note that the connector is wider at the top (notches near 21 and 40 on the side guides if that makes sence).
Pin 18,19 and 20 are +12V. There's no block of GND pins like I was expecting, instead GND is connected to 3, 6, 21, 24, 27, 30, and the connector shield. Due to the pattern of the gnd contacts, i'm guessing they're the shielding ones for HDMI. The connector is rated for 1A power per pin which means you need to use at minimum 2 of them.
I still haven't seen anything resembling USB and noticed that the tablet only uses a 20 pin zebra cable to the connector board (power included though they may pass GND through the case).
Now that I have my proper electronics desk at least partly set up, I can look further into the connector.

Every now and then you find things that make you just exclaim WTF at the top of your lungs.
The dock connector board located in the tablet does not appear to have HDMI signals on it. The zebra cable between it and the mainboard has 20 pins. 17-20 are +12V, 12-15 are GND. I'm having troubles doing continuity tests between any of the HDMI signal pairs and the other pins on the internal connector.
Bad news on the USB front, there is no 5V and all the USB pins internal to the tablet float at 0.067V disconnected and I don't see similar levels on any of the pins.
It's looking more and more like the dock was designed for a completely different product. Can someone over where the HDMI capable docks are available check their tablet internals and see if the connector board is any different. Alternatively can someone test one of the HDMI docks to see if it even works with their tablets.
I'm working through the tablet side right now, I'll take some pictures and document my findings in a little bit here.

That being said - anyone wana mod their tablets? I was thinking adding a tiny USB hub in where the USB cable runs and make a new dock connector that has USB on it (taking over for the stupid serial pins maybe). Would need a new series of docks (or mod boards for the docks)... maybe a silly idea though
----
Oh, also, is there anyone even interested in me reverse-engineering the serial protocol used for the IR control? I can probably do so with some time but it'll require me to reformat my tablet to factory as none of the other ones seem to support the dock.
:facepalm:. I bet they designed this port, initially, for their own proprietary means in a lab/repair environment, and said "Ya know, if we're gonna have this ugly port on the thing, may as well find something that the consumers would be able to use this for", thus coming up with the dock and only for syncing...
Acer UK store( http://store.acer.com/store/aceremea/en_GB/list/parentCategoryID.55934900/categoryID.56077100 ) claims that the HDMI version of the dock is only for the A100/A101 while the non-HDMI is only for A500/A501.
Power up tablet throught dock port
Anyone knows if it's possible to send a signal to power up (as if you push the power button) to power up the tablet?
I know that they have a powerbutton on the remote but i don't know how to do it to start it.
Thanks!
I purchased a usb type c to hdmi adapter and when I plugged in it said g6 does not support slimport and to use miscast instead, but my question is IS slimport hardware or software based function, thank you.
I' really like to know this, the lg site says the phone supports MHL. How is a MHL cable different to a usb type c to hdmi?
MHL, Slimport, HDMI and Miracast are all different technologies.
You're honestly better off getting a Chromecast. If you absolutely need to mirror, then miracast.
The USB ports on devices these days are non standard, and there is a lot of confusion about what is supported and what isn't.
As a rule of thumb, mobile devices only support faster transfer and power delivery, but not the additional hardware for multi screen support or others
Well I bought a oculus rift a week ago and trying to use it as a fpv with my drone and the rift has hdmi input so is the reason I brought this cable but g6 does not support it and even my rift doesn't appear to power on unless connected to pc and oculus app running to provided video coded for it, but is slimport a hardware or software based function.
Disclosure of Material Connection: I received this product for free in a giveaway. I was not required to write a review, but I chose to do so. I am disclosing this in accordance with the Federal Trade Commission's requirements.
I recently received a Choetech USB Type-C to HDMI Cable Review (model XCH-1201BK) in an online giveaway. The company Choetech has many different adapters, so make sure you look at the various options to determine which works for your intended use.
The cable itself came in a nifty little round case that has enough space to hold another small cable or maybe a memory card making it a useful carrying case. The cable itself has a USB-C plug on one side, and a HDMI connector on the other side. You can read all the details on the company or Amazon page ( links at the end of this post ) but here are some key points:
- Supports 4K @ 60Hz resolution
- Support DP Alt Mode ( NOT MHL or Slimport, make sure your device is compatible )
- Does not charge your device while playing video, but Choetech does have other adapters with that option
To test the cable, I connected it to my HDMI TV and my Samsung S9 Plus. The video immediately came up on the TV, then I proceeded to test multiple video applications:
- Google Play Movies
- Netflix
- YouTube
- Crackle
- Movies Anywhere
- Hulu
- Tubi TV
- PUGB Mobile
All the applications displayed on the TV with no problem. I didn't get any error messages or warnings from the movie apps. I don't remember the exact adapter, but I know that in the past I would run into issues using HDMI adapters ( MHL or Slimport I can't remember which ) because certain applications would not output video. I think this was some sort of security related feature, so I was happy to see that this Choetech adapter worked just fine.
I plan to continue testing the adapter, including watching a full movie or multiple TV episodes to see if I run into any issues and will update my review as necessary.
Here are the main points I noticed about the adapter:
Built-in HDMI connector: You don't have to carry around a bunch of extra cables, just this one adapter that can plug into the HDMI input that most TVs / projectors have. I do have a HDMI to VGA adapter (for a computer monitor) that had a male HDMI connector so I couldn't plug it into this cable, so depending on your scenario you may want to consider other Choetech options.
Angled connector: If you are going to use this with a smartphone, the connector will help keep the cable out of the way if you are holding the phone. It should also help keep the plug tidy coming out of a laptop since you can run it along the side of the laptop instead of just sticking out.
Easy to use: On the Samsung S9 Plus there was no special software or configuration required, it worked as soon as I plugged it in.
Bottom line: Great USB-C to HDMI option to consider, and if this isn't exactly the right one for you Choetech has other options.

You are correct it does not charge the device, but like I said they have other options. This one ( https://www.amazon.com/dp/B078M57FVJ/ ) should work. As for the mirror view / DEX aspect, I don't know since my device is stock.
