I was just looking into what all the pins do because I planned to make a small board with A and B connectors and wire the resistor in there. Now I see that's pointless. I figured the shielding on other connectors was equivalent to the 5th pin.

I'm going to have to strip down a micro USB cable and see what I find in there.
[Galaxy S III Accessories] Fallon:
I'd recommend looking at that breakout board from Spark Fun I linked up top.

Mentions 365k as well as 1k to trigger desk dock. will try it when I get a chance.
[Galaxy S III Accessories] KeithLM:
I've stripped down a micro-USB connector on one of my monoprice.com cables. I've found that the pin is there on the backside of the connector and just not connected to anything. Unfortunately I did too much damage in the process to try and reuse it. I think if I can strip another and be more careful I can expose just the one pin I need, then expose some of the wiring further from the connector and very carefully slice open the ground and connect the two with the resistor. It's also possible the shielding is connected to ground, so I might be able to attach it directly to that. Unfortunately my voltmeter is out of commission so I can't check that at the moment.
[Galaxy S III Accessories] mikejr83:
Ok. To clarify, the ID pin doesn't have a wire/conductor that runs the length of the wire?
[Galaxy S III Accessories] KeithLM:
Definitely not in the cable I pulled apart. I've looked around for a micro-USB extension cable, but haven't found one so far. Potentially such a cable would have the fifth wire.

Straight from the land of the rising sun! Straight from China! http://www.ebay.com/itm/10Pcs-USB-T...ltDomain_0&hash=item20c49dfc46#ht_2925wt_1163

DIY Micro 5pin male USB connector! $4 for 10 of them. I just ordered a set. Once I get these it should be easy to build a test connector that will run through my pot so we can try different resistances.

This is what I was hoping of finding. I wanted to take a 1.5-3ft USB cable and put an end on it that would put the phone into desk dock mode. That way I could connect the cable to my keyboard and set my phone in a cradle that I previously purchased.

EDIT:

Shipping is a $1. Total paypal amount was $4.99

EDIT 2:

I'm a tard. Also got shipping confirmation. Could take up to 30 days :(. Hopefully it's on the shorter side of their estimate of 7 days. I guess that gives me some time to put together a monoprice order for some cables.

USB 1.x/2.0 Mini/Micro pinout

Pin Name Cable color Description

1 VBUS Red +5 V

2 D− White Data −

3 D+ Green Data +

4 ID None Permits distinction of host connection from slave connection

* host: connected to Signal ground

* slave: not connected

5 GND Black Signal ground

So definitely only 4 wires in a standards compliant cable, not 5. Pin gets left free or shorted directly to ground (or shorted via a resistor in Samsung's case for dock mode)

Nice find on the cheap micro USB connectors.
[Galaxy S III Accessories] mikejr83:
Now that I'm at work and doing nothing really important I've had time to dig through digikey for a similar part. I just don't think I can wait that long to get those other pieces!

The only thing I've been able to find that is close is this:

http://www.digikey.com/scripts/dksearch/dksus.dll?lang=en&mpart=10104109-0001LF&vendor=609&cur=USD

I ordered 3 and had them shipped USPS First Class. That will give me something to test with hopefully by the end of the week.

BTW, it's been such a long time since I ordered anything from digikey that I didn't realize they dropped their minimum order size requirement. It's awesome that they'll ship a $2 order!

Check GPS USB cables... they have all 5 leads

The USB extension cable is common for GPS units. My car radio has garmin built in, and when I added the fm traffic antenna, I needed a Mini USB (not micro) cable and quickly found out that "standard" off the shelf cables only have 4 wires, when the mini and micro usb ends actually have a 5th pin, but it either gnd or n/a at all - the standard extension cables off the shelf are extremely cheap, but useless for an application where the 5th pin is needed. BUT when I search for a GPS cable, it has all 5 pins. Its also about 5x more expension - When I bought mine it was like $25 or something online, but I can't remember where... it was from a GPS outlet place I found online. Just posting my limited experience for those to consider, and maybe prices have changed since then?

GOOD LUCK

Got my cheap SGS2 Zenis dock in. Fits the SGS3 ok, but no dock mode, as half expected. Should be trivial to solder in the right resistor as per teardowns in other threads (when we get the right value).

http://xdaforums.com/showthread.php?p=28013773

Shipping took maybe 2 weeks & my black dock has a grey rubber filler pad rather than black.
[Galaxy S III Accessories] mikejr83:
I don't know how keen you are on tearing that thing open (:fingers-crossed:), but if you are could you check to see if they have any resister on the ID pin?

On another note I've been searching for dock and DIY related things and haven't seen much in the way of the SIII. The SII and Facinate seem to have a fair bit of information on the Googles. While looking around I was reading up on the Nexus S dock: http://www.samsung.com/us/mobile/cell-phones-accessories/ECR-D1A3BEGSTA. This description by Samsung says explicitly that it will work as a multimedia dock with Desk Home. This is not how the SIII dock is described. I'm wondering if anyone out there has a Nexus S dock as linked and would be willing to check out the resistance on the ID pin.
[Galaxy S III Accessories] Fallon:
Willing & able, yes, but finishing up a class then getting ready to take off for DEFcon, so probably not until next month. The pictures I linked above are pretty good & don't show any resistors. My phone does not trip any kind of dock mode on it either, so if there were any resistors, they wouldn't provide useful information.

Ya, there was a lot of research & info for the SGS1 phones back when I first got my Captivate, haven't seen quite as much for the SGS3... Yet (I hope).

Confirmed Samsung Media Dock Starts Desk Dock Mode

So my better half, who dismisses much of my ramblings about phones, xda, etc; gave me a Samsung Multimedia Desktop Dock for the S3 for my birthday. I opened it this morning and quickly saw that if you have an otterbox or any other such case it will not fit on the dock. I pretty much figured this would be the case from the get-go, which is why I didn't really want it, but it must have gotten included in a list of suggestions for birthday purchases.

It's actually a really nice dock. My biggest gripe is that it holds the phone in portrait instead of landscape.

Anyhow, I took the case off of my phone and put it into the dock. It made the dock noise and sat there. I was a bit confused as the noise was different than the usb noise. I ended up unlocking the phone and saw that it was asking me to chose between some "clock dock" application and "tunein". I selected the "clock dock" app and it went into dock mode. I locked the phone and it stayed on as it should and could be displayed in landscape mode.

I guess my next move is figuring out how to disassemble the dock and find out what resistance is on that ID pin. I haven't started searching yet, but does anyone know of a tear down of the dock?
[Galaxy S III Accessories] mikejr83:
Tear-Down of Samsung Multimedia Dock

Ok, here's a complete tear down of the Samsung Multimedia dock. I don't have a picture of the box, but it says that it's universal for "Galaxy S". However, this is the dock that is listed on Samsung's site for the S3.

Things to note: This dock is just a very sophisticated version of the charge/dock/audio out cables that have been linked in this and other threads. It looks like there may be a few capacitors (C1-C4) on the board. This may be fore the audio out. I'm not really sure. There is no marking on what value they are.

Images of the tear down; if you can't see them click on the link below the image and it should link you to the picasa web album.

Taking apart the dock:

Link

This thing sucked getting apart. The rubber mat is held on by sticky and is pressed up into the sides of the dock. I just pealed back the the edges at first but after realizing there were more screws than four at the corners I took the whole thing off. It goes back on pretty easily and you shouldn't need any extra glue to make it stay once you've re-press the sides Take out all those screws. Then you have to carefully work a flat head around the sides so you can pop the tabs on the inside.

Dock apart:

Link

Close up of board in the dock:

Link

Getting those four screws out is a PITA!!!. I stripped one and had to work it out with a T6 bit! IDK why they're in there so tight.

Just board:

Link

So here's what I can't figure out. I've put a trace on the outside shielding of the plug that goes into the phone and the ID pin (nicely labeled on the PCB) and get no resistance value or continuity. I see only one R1 on the entire PCB but I can't seem to figure out where to read it's value.

Suggestions welcome!

EDIT!

FIGURED IT OUT! Goes to show you that after having a half a pint of a Belgium dubel things in the ol' noggin' start working better!

Looks like I'm reading 369.3K Ohm. 5% tolerance should put that between 350k - 365k (I think). I'm going with 365k as a starting point. Will start a new post once I've soldiered onto the my plugs that arrived today!
[Galaxy S III Accessories] Fallon:
That matches the 365k I posted earlier for the SGS2. Excellent work. May or may not have time to solder one on my dock before DEFcon next week.

Ok this is going to sound stupid but here goes.... What is the advantage of having the phone go in to dock mode or car mode?

I added the touchstone wireless charging mod to mine, and have played with turning on driving mode (says driving not car) from the notification pull down menu, and I see no difference between driving mode and not driving mode.

I'm sure this is user error (my fault) but I have no clue. Any advice would be appreciated

[Galaxy S III Accessories] Fallon:
I use tasker on my phone....

Bedtime mode (currently via NFC tag), mutes everything but the phone ring so I don't accidentally wake up the wife. Driving mode (via car dock), turns on bluetooth, kicks off the desk dock app (bigger buttons to hit easier while driving). Etc.

By default car mode & desktop mode only kick off the appropriate dock app. It's nothing earth shattering, just convenient.
[Galaxy S III Accessories] Araltd:
How can I see this? anyway to test? I toggled on Driving mode in the pull down, doesn't seem to do anything.
[Galaxy S III Accessories] KeithLM:
Araltd, I did not find an actual car home app on my phone, rather it just wants to invoke S Voice or something like that. You have to install a car app home from the market. I'm using CarHome Ultra at the moment and it's rather nice. I used to use Custom Car Home however it doesn't scale to larger resolutions like on the S3.

CarHome Ultra can also trigger off of a bluetooth connection. So that's what I'm using at the moment. I find it works pretty well. If the phone is not plugged in when I get in the car and the screen is off it doesn't change state, but the moment I plug it in, or if it's on and I turn on the car it goes into the car mode and CarHome starts up. Makes things quite easy for me. It also shuts off car mode the instant the bluetooth connection is dropped. It also allows you to set a custom brightness level and that changes state correctly also, unlike Custom Car Home which could force the phone to full brightness, but would leave it there after I pulled it out of the dock.
[Galaxy S III Accessories] Araltd:
OK.. now I don't feel stupid anymore. I couldn't figure out what I was doing wrong, I never saw anything about a "car" mode except for the driving mode toggle which as I stated, doesn't seem to do anything whatsoever.
[Galaxy S III Accessories] mikejr83:
You can view desk dock by going to Clock and selecting the "Desk clock" tab. You can then hit the expando icon. When you actually put the phone in the dock it behaves a little different, but it is the same thing.

Basically I like to sit my phone at my desk and have the calendar and time show up all the time. There are other dock apps that can override the default. There was one that used to display a news ticker and upcoming appointments. I forget the name or if it was in some ROM I had for the DX. It was useful.
[Galaxy S III Accessories] s'pht:
So I looked around a bit and found this post http://xdaforums.com/showthread.php?t=820275 that talks about audio getting sent over D+ and D- (left is D-) on the original S. Is it the same way on the S3? If I'm going to be putting together a cable to enable car mode I might as well wire it up for audio too.
[Galaxy S III Accessories] mikejr83:
It appears that way. I put my multimedia dock back together, but I clearly saw the traces coming of the header for the USB headed to the line out jack.
[Galaxy S III Accessories] mikejr83:
Got the ends today. Just need to figure out the pin-out.

Is three pin side the middle three pins in the plug? If so I guess the middle is id, but which is signal ground? EDIT MESSED UP ATTACH.

I guess these are the outside two?

Ideas? Sent an email to the seller on ebay. Waiting to hear back.
[Galaxy S III Accessories] mikejr83:
Here's the 3 pin side.
[Galaxy S III Accessories] KeithLM:
I believe the pins on the three pin side are the odd pins. With the three pin side up and the connector away from me the ground is on the left. The ID pin is then on the bottom left and red is on the top right.

If you do make them, especially potted with the epoxy, make sure you leave some part of the trace & resistors exposes so that it can be further modified.

Help With Pin Out

Hey guys,

I have all the components to build my "home dock" cables. The problem I'm still having is I can't find a pin mapping/diagram for these micro USB plugs. Googling does nothing, at least Googling for "micro male 5 pin usb plug pinout" and other variations. Can someone help me out by finding any kind of documentation that would show the mapping from the soldier points on the back of the plug to the pins in the plug?

As I mentioned previously I tried emailing the vendor, but I'll put it up to cultural differences that they're unable to provide much help. All they were able to get out of the conversation is that I wanted the USB 2.0 cable spec. They unfortunately haven't answered any emails since then.

My probes for my multimeter don't hit the pins reliably enough to figure out the mapping.

Here are some pictures of the actual plug.

I think KeithLM may be correct that the "3" side is the odd pins. From my own testing the outer two pins on the 3 pin side are v-/v+ (as labeled on the board for my Samsung dock). I think this translates into one pin being Vcc and the other ground.

This would match up to this diagram:

Forgive me drawing this out, but I'm trying to make sure I have this correct before I start soldiering a bunch of stuff up. I'm trying to figure out this based on KeithLM and my observations:

Looking down on the plug with the soldier points to the back :

top of plug

| | |

1 3 5

bottom of plug

| |

2 4

If it is the above, I swear I got nothing from the phone when going across 4 and 5 as shown above. I thought that it might be 1 and 2 (again according to the above diagram) which made the phone trip the same noise as charging. If I have one plugged into the phone, should I be getting voltage across 1 and 5 (Vcc and Ground)?

I only fiddled with it for about 30min last night before I had to take care of other stuff. Tonight I should get a chance to make a plug with the resistor soldiered on it.
[Galaxy S III Accessories] Fallon:
Your Thice.nl image looks correct, except for the fact pin 4 (the ID pin) is unlabeled. Pin 4 & 5 (ground) need to be shorted with the resistors to trip the dock modes. There should be 5v across pin 1 & 5 when plugged into a charger. I can't really help analyze the pins on the back of your plug as there is no standard for that side.
[Galaxy S III Accessories] mikejr83:
Dock Cables Have Been Made

So I have a desk dock cable and a car dock cable now.

Here are pictures of the internal setup. Everything is so damn small it's hard to fit inside the plug housing. I have a better idea of how to make the cable for version two. Unfortunately all the cables I ordered from monoprice have the ferrite cores on the end. Cutting the cable after the core just makes it short. I guess I'll have to be putting in an order to get longer cables...

The plan for v2 is that I'll move the resister down in line with the cable and make it so that all the pins on the plug are wires instead of the thicker resistor wires. I'll just heatshrink over the resister and exposed cable spots.

The pictures show how the cable is assembled. Just the shorted pin, ground, and v-. This cable puts the phone into dock and charges it. No data.

All pictures from the builds - Google Picasa Web Album
[Galaxy S III Accessories] Fallon:
Ferrite is pretty brittle. If the plastic coating isn't bonded to the cable sheath, just whack it with a hammer and it will shatter without harming the cable.

Does either of these dock modes enable landscape mode for the main interface? I can only get landscape mode when using an MHL cable with my tv - but if a custom cable could enable it, I'd be eager to buy and/or mod one myself.
[Galaxy S III Accessories] Beemer533:
They should... I don't have a desk dock, but my Infuse car dock does put the phone into car dock mode, after which the phone allows home and lock screens into landscape. I think that as long as it has the correct value to set the dock mode, the phone will allow landscape mode....

Hopefully this helps:

I took apart a cable and connector i had on my desk and did a continuity check (I have leads for my Fluke with really small pointy ends for circuit boards).

Here is a screen shot from my SG3 of my ElectroDroid app (Awesome app BTW)
[Galaxy S III Accessories] mikejr83:
Thanks for that picture. It's going in to the Evernote for safe keeping!

Dock orientation depends on your ROM and what you have setup to handle the dock modes. I'm currently on CM10. With CM10 clock opens in clock mode for desk integration. You can get Desk Dock Plus from the market and it will open as well. With either of them they depend on the orientation of your phone. If the phone is in landscape they will display in that manner. Also, with CM10 the car dock depends on which orientation your phone is set in, although I've only had it in landscape with the CarDock app.

In stock TW I forget what opens when you're in car dock mode. For some reason I thought I had to slip in the CarDock app because it kept wanting to open the stupid Vlingo or VZW Nav apps. The desk dock mode for TW was actually nice (I kind of miss it). It would work in either orientation but looked really nice in landscape with the calendar on the screen.

No portable kids Blueray players, and any other output from mobile device for auto will not be True Hi-Def...screens in auto aren't in that settings scales yet....way too much data, speed etc needed to be practical....then something has to have hardware to convert from digital to analog and vise versa...And USB will never be able to handle a true Hi-Def signal and one 1080 movie would fill phone's total gigs up.....lol
