Anyone know of a micro USB to RS232 Serial adapter?
or for that matter if the Epic can be used in USB Host mode?
My goal, is the be able to use my Epic 4G to run a terminal link to some control boards using ZiLog Z8F processors, I work a job as a field technician on energy management controls. Currently I lug a net book around to flash and terminal into the controls.
If I could do the same without having to drag my net book with the rest of my tools, that would be incredibly awesome for me, I'm always trying to find ways to minimalism the amount of gear I have to carry from my truck to the boiler room.
Thanks
The only thing I have seen that comes close to what you are asking is this thread in the dev section: http://forum.xda-developers.com/showthread.php?t=833373
I dont have any information other than the link, but thought I would at least point it out.
Thanks, at least now I know where to ask questions and pick peoples brains!
If you could find the appropriate cord and drive it from your epic.
I used this back in the day (not from a phone) when I lacked a RS232 port on my devices...
I have seen adapters that would likely drop the usb to micro easily enough but.. thats the least of the difficulty

really not sure if it could even make this work from an epic, lacking any readily available drivers though.

If you can relax your requirement for USB, then use IOGear RS-232 Bluetooth Serial Adapter (model GBS301). I use this along with the app BlueTerm on the market. Works for all of my RS232 needs.

Might be worth a shot. I didn't see anything looking quick, but I know they have lots of different options and if all else fails custom build components as well.
A USB serial adapter won't work with the stock rom (or any custom rom not implementing usb host/otg).
In theory, it's possible to repurpose the usb port's pins as gnd, txd, rxd, and a resistor of specific value that tells the phone to electrically route their signals to pins on the SOC chip with txd & rxd functions at nonstandard voltage levels, but I'm not aware of anyone who's literally gotten it to work on the Epic, yet.
Note that serial via this method has *nothing* to do with usb; it's just temporarily repurposing the pins & connector for serial use.

Hello all!
I am looking for an awesome dock for my SGS, it's the GT-I9000 from Europe. I am in the USA and I am not familiar with the compatibility / interchanges on the various models.
If anyone has any suggestions for a dock that would be cool!
Would like to have one by my bed and one at my desk. So I need to be able to connect to PC while docked and if possible access 3.5mm port as well, for TV out.
Thank you for your help!
Did you check ebay? there are various cradles for SGS
Yea I did most I find won't let you sync while docked, or use the 3.5mm, only charge.
And I don't want to use a dongle, I just want to plug it into the dock.
Thank though
Just get the official samsung dock, it's pretty nice, lets you do all of that. Automatically puts the phone into the home dock mode too, which is nice.

~Edit - Sorry that one looks like it is for the epic 4g, which is thicker than our phone due to the keyboard, but the dock might work, it depends on whether the USB is on the lower or upper half of the epic if you know what I mean. This one would work for your phone and it's only a few dollars more:

Thanks Nirvana388,
I do however need to be able to sync my device with kies and use the mass storage feature through the USB of phone while docked.
Correct me if I am wrong but, as far as i can tell neither of those cradles allow syncing while docked, and for me that kinda defeats the purpose of the dock/cradle, it is instead a glorified charger. The ads are very deceiving and the only reason I know that those features are not available is by reading the customer reviews.
Thank you for the suggestion though

As you can see from the pics there is a microusb connector on the back, just make sure the cable you insert there is in fact connected to your PC.
I've bought a cheapo cradle off of ebay, works fine for sync and charge, has a usb cable and also a charger! But it does not have the 3.5mm connector so not sure if it would be any good to you. http://cgi.ebay.com/USB-Sync-Dock-C...393647?pt=PDA_Accessories&hash=item45f84ac72f
Just a few posts down from yours is this

After buying the dock and seeing that I've paid $24 only for a piece of plastic with a connector I decided to dig a little deeper into it to make it better.
So, I was assimilating information from these topics:
http://forum.xda-developers.com/showthread.php?t=1155065
http://forum.xda-developers.com/showpost.php?p=16342363&postcount=4
I started to put my knowledge at work and this is what came out - see attachments.
Basically I can now use my charger of choice and at the same time I can plug in USB stuff.
The small relay inside is switching the power supply for the USB host from the 5V output of the tablet to the main 5V supply when you are plugging in the power adapter (the original or non-original).
The button next to the USB host (I know .. it is white .. but they were not having other colors at the electronics store ) has the function to switch the connection of the USB port from the regular OTG to the circuit that is enabling the AC charging on the tablet. So, when I'm not using the usb host capabilities the tablet will charge in fast mode, with full current.
There is one interesting thing I've found. If I'm plugging in the tablet with the switch in the fast-charge mode and after that I'm switching to USB-Host mode, the tablet will still continue to charge in AC mode (see snapshots for proof ).
I have to mention that all the original functionality of the dock has been preserved and the 30 pin connector at the back can still be used with the original intent (with the proper cables).
If anyone want to replicate this mod and needs additional details, just ask and I'll gladly answer.
Very cool. Lots of great details and pics.
One word: Brilliant.
Good work mate.
Awesome what about a HDMI port?
Sent from my Samsung Galaxy Tab 8.9 using Tapatalk
The hdmi has to wait a little. I have ordered a mhl adapter on ebay but is gonna take a while until will arive. An on top of that I need to find time in my crowded schedule.
Could you please supply the wiring schematic diagram of your mod? That would be a lot helpful. Thank you.
This is awesome, great work! Shame it doesn't come with that full USB port stock. If I get one of these tabs, I'll definitely be looking to repeat your work.

awesome, can't wait to see your update of HDMI
I'm sorry not to have provided the requested info but my daily job is currently killing all my time (including the theoretically spare time). I'll draw the schematics ASAP and also I'll re-order the MHL adapter since the first one got lost in the mail (and I've been reimbursed).
Anyway, as a heads-up - I'm thinking to put the MHL adapter on top of the dock so I'll keep the original port accessible (and also the audio jack). I still don't know how exactly I'm going to do this ... but I think I'll figure it out when the time will come.
thats quite innovative

apparently the dock has hdmi passthrough meaning you still need the samsung hdmi adapter (http://www.samsung.com/us/mobile/galaxy-tab-accessories/EPL-3PHPBEGSTA) I haven't yet tried my dock with my hdmi adapter, I will do tomorrow and let you know - good luck incorporating that too
awesome job mate...schematics would be really helpful. Can't do this mod on my own, but my father is more than capable...I think i have project for him (if you can find some time to draw those schematics off course )
Would it be possible to modify the dock to disable data and only enable AC charging? I'm using the Tab in my car and every car charger I use seems to only send 500mA of current to the Tab so it dies a slow death in my car and needs to be recharged at home once a week or so.
Any suggestions?
Thanks
Can you show where you soldered wires to in the dock?
Bought one and want to charge at same time as watch movies from usb device.
Anybody help me?
Have you thought about making and selling these?. I for one would certainly buy one!. Wouldn't have the balls to try and do it myself...... av
Hi guys,
I've put together some schematics. Sorry for the lack of very deep details but I can not take the glue off my board and other hi-def picture I was unable to find so you will have to use an ohmmeter to find out the exact pins based on the clues in the picture.
Basically, in the attached picture is the implementation I currently have in the dock. Due to the lack of free time I was unable to continue with implementing the MHL adapter inside so I guess I'll drop that one.
If you need any details based on the attached picture do not hesitate to ask.
Full size picture: http://img822.imageshack.us/img822/83/dockmod.png
And to answer the ones asking if I'm thinking to sell these : Actually that thought crossed my mind. I have other mods done on my Galaxy Nexus also (see the Ringke inductive charging mod) and also other great stuff that I'm building by exercising my hobby. Unfortunately, when I'm pushing like 70-80 hours a week on my daily job there is little to none spare time left .. and the little I got I'm spending it with my son. In a relative future when I'll have more spare time (or no job) I'll consider starting a business based on the know-how I've gathered until now.
thanks for update...
Just purchased the break out board so when arrives will give this a go!!!
Also found this if anybody wants to try the dock...
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
usb host, hdmi & charge...AT THE SAME TIME!
I just wanted to point out a similar thread posted in the "galaxy tab plus accessories" forum. This may have already been done before but i figured it would be much bigger news if so. XDA member "emil_b" claims to have modified the multimedia dock to simultaneously do hdmi out, trickle charge the tab , & serve as usb host! In case some of u may not know, the same dock works with ALL tab variants(PERSONALLY ONLY TESTED WITH P1000, P7100, P6200, P6210 BUT 99% CERTAIN) so if this proves true, this should be shared with all the other tab forums in hopes that it can be made into an actual product.
Here is the original post

Ended up modding my dock now and have usb host with charging...
Thanks Ro-explorer for the idea...
old dock from samsung p1000...
i have from my old p1000 (i sold it) the docking station at home. mhm i think they have the same cabel and so.
but the p1000 have 7zoll and my tab have 8,9 and the pin is landscape
i cut the dockstation and my GT-7310 works wonderfull with the ( i say modded ) dock.
mini hdmi works and the rest too. only one problem is there now, i but a little piece of paper behind the tab and dock, for the perfect fit xD
okay the cuts look terrible but i work on them
sorry for my english but i hope you can see on the pics what i mean gg

I know this is probably more for Microsoft Surface Developer Section but seeing how I am still pretty new I don't have enough post to be able to post in that area.
I am mainly curious if anyone knows the pin outs for the Touch/Type Cover connector on the bottom of the tablet and if it uses standard USB or if it is some kind of special propitiatory type connection that would say connect the keyboard membrane to the keyboard controller that may be in the tablet? If it is just a standard USB connection I am thinking about cannibalizing a touch cover to see if I can create a home Grown Dock so to speak for the tablet that would have a USB hub for keyboard and mouse and a USB to Ethernet adapter that works with the tablet. The USB hub will draw power from a modified Power Cord for the tablet IF I can figure out that electrical later on to where it wont fry my tablet or other accessories but first I need to figure out the first part.
TLDR Does anyone know if the touch/type cover user a standard USB protocol and if so what is the pin layout for the connector on the tablet. If anyone can help that would be appreciated.
I just received a surface and they through in 2 type covers. said, "keep it" on a sticky note. I am now working on figuring out what the connectors are. I dont see the point of having 6 connectors, so I think that some may be ground or false. I will open up one of the keyboards to see what ships they are connecting to. i would think it has to be usb. I know that the 6th pin, that is 6th from the left pin, is 1.8v when grounded. I am guessing that the voltage goes up once the surface detects the attached keyboard. I will write back, let me know if you have figured anything else out. seems like we are hte only people on the internet who even care at this point. and microsoft is literally giving away surface computers.

any progress?
i already build a power wire, with a 5,5mm plug to connect it to my Intocircuit PC26000 for more juice on the go, and for a second charger.
you can see the pinouts of the power plug in the attatched pic.
let me know if you got any results for the cover connector so far - if its USB, i will implement my UMTS stick into a cover
Cheers!
just got pictures of the cover connector, see attatchment.
in fact all the 6 pins are connected. USB 2.0 would take 4 of them.
my guess is that one of them could be a switch, to turn the device & keyboard on and off.
any progress
Curious if anyone has made any progress on decoding the pinout, figuring out if it's usb or not?
i didn't do any further research - but it guess it's usb, or at least kind of... as it shows up as USB device in the device manager...

Judging by the connector and the fact that the covers are USB-based and can be used reversed, the pinout makes perfect sense. The likely possibility for the pinout is as follows:
Power Cover connector (Using pin labels in picture)
1/10 = Power cover +ve
2/9 = Power cover Ground
Touch/Type connector (Using pin labels in picture)
3 = +ve
4 = Ground
5/6 = Data +ve or -ve (reversible internally)
7/8 = Attachment direction detect
Pins on Touch/Type cover itself (Pinout from left [1] to right [6])
1/6 = +ve
2/5 = Ground
3/4 = Data +ve or -ve (reversible internally)
As to if the USB data pairs are swapped on the SP or the Cover, we cannot know without more information. Depending on the voltage supplied or the presence of unauthorised hardware detection (e.g. the ID chip in Apple earphones, I doubt it), custom USB devices should be fairly trivial (electrically).
I know this is an old thread but has anyone made any further progress on this? If not, I'm considering experimenting myself with a spare touch cover and a raspberry pi

Nope, im sorry, i didn't make further progress on this, exept what i already posted.. it is a USB connection, you can easily verify that yourself by looking at the Touch/type-cover in the device-manager...
I guess you can easily connect other USB devices if you build yourself an adapter..
but there could also be some kind of verification, if so then its most likely software based, if you hit a barrier, try reverseing the type-cover driver, you might find something there...
One additional info: the big outer nipples can be used to charge the device.
Peace
If I were to leverage the bottom grooves for charging, can you tell me which pin is which? +/-

Hi tfBullet,
When you say "the big outer nipples can be used to charge the devices" are you referring to these...
Power Cover connector (Using pin labels in picture)
1/10 = Power cover +ve
2/9 = Power cover Ground
Any new discovery?
Any new discovery?
will the power output still be live, if the data signals are not shorted? e.g: IOS devices
Can we just connect the keyboard via usb to a windows pc?
I don't think this is true USB, as there is no 5 volts anywhere on the connector, only 3.3 volts.. It may be USB, but needing to be level-shifted before you can use it. It may be potentially a way to get another USB port on the damn thing. Why did they think one USB port is enough? I have been trying to boot it from flash drive, but need keyboard as well, but the USB will not boot with a hub connected. Grrrrr.

i want to connect the keyboard itself to other devices
Hey guys
Good thread going on , i would like to see if any one of you ever thought about to use keyboard itself not the port , for some reasons I would like to use the keyboard on other devices (i mean kinda convert the pins to a USB port and use it on other pcs or what i really desire about is using it on Xbox) i want to see if any of you have any ideas or information about this , i mean is this even possible ? I've read the whole replies and most of them were about the port on surface and yeah its really cool , but i want to see if its possible to do , cause if its possible then it would be a lot easier than the port on the surface
Thanks

Well, take a look at the link Neakmenter posted, the guy there analyzed the communication, turns out it's no standard USB, it's proprietary.. Which means, there is no easy way of using this keyboard anywhere else than the surface... You would need some kind of microcontroller which connects to the keyboard, interprets it's signals, and relays them as Standart HID signals to a USB port..
The connector alone is a problem as well, you'd need to 3D print a connector or something like that, it's just not worth the effort i guess [emoji2371]

Hey guys,
i need some help / ideas for the best solution for my "docking"-problem in my car.
I have a bmw and since there are no snap-in adapters for htc i have to go over audiojack for listening music with spotify and i can't just put it to the place where the audiojack is because i have to control music with the touchscreen (iDrive 1 so no bt-audioplayback/control...).
Now i got 2 problems:
1. the cable looks ugly when its plugged in the phone and
2. i have no idea where to place my holder because every place i put the ugly holder the car looks cheapy.
So, my idea is to go over the pogo-pins!
Yeah pogo-pins but i don't know the assignment of the pins so the solution would be the cr s650 dock.
BUT! i think i my car won't be able to provide enough power through usb (is it possible to power the dock with usb?!).
The plan was to place the dock (please see the attachment) in the red circle and put the cable under the cover to the usb charger and the audiojack.
And also i have to modify the dock so i can plug in a jack into the dock or just solder a cable or whatever...
So my questions are, do you think this will work? And what problems i will have implementing this? Any other better ideas maybe?
Thanks for help and sorry for my bad english i think
No ideas?

I have no idea about the pogo pin dock, but I would avoid making any permanent modifications to a BMW and deal with the ugly look...it will decrease the resale value...you could always take the dock down when not in use (which is what I do)
Regarding the pogo dock, Make sure that the phone stays still and will not fall off the dock with some hard driving.
Not the prettiest solution, but I use this: http://www.amazon.com/Mountek-nGroo...1131802&sr=8-1&keywords=cd+player+phone+mount
and just hard wired a power cable behind the dash (as to not have wires all over coming from my cig lighter)
The reason I went for that dock is because the phone is a lot closer and more accessible vs mounted to the windshield or elsewhere...also, regarding your proposed placement: having it down by the gear shift while driving would be pretty disorienting to me using GPS
