Hi all,
I have a Philips AS111 docking station/bluetooth speaker/charger. Worked perfectly for my SGS2, however, since I bought a new phone (Sony Xperia Z1 Compact) I'm experiencing some problems.
I bought an micro usb to magnetic connector adapter to be able to connect my phone to the dock without having to open the flaps all the time. I took it apart and it basicly splits the first and fifth pin of the micro USB connector to the pins in the magnetic connector. Unfortunately I may not link to external images...
Unfortunately, my phone does not charge when using the adapter in combination with the Philips dock. It does when using the original Sony USB charger and the adapter, so the adapter is fine.
I measured the voltage on the two pins, and it's 0V. I even tried to fool the dock by putting a 1.5kOhm resistor over several lines. Only when I put a 1.5kOhm resistor between 5V and the connector housing, the dock responded by turning on Bluetooth. Voltage went crazy, flipping between 0 and 3V, but phone still doesn't charge.
I think the sollution is to fool the dock by putting a certain resistor between certain lines or by shorting certain lines. Does anyone have a clue how to fool the dock to think there is a device connected, so it opens the +5V line?
Thank you very much!
Nobody into usb connection protocols? :crying:
Finally got it working. Eventually I needed to connect two wires together inside the device. One of them being 'CLAS1' and the other was Ground. Both could be found on the connector going to the micro usb plug of the device. Unfortunately I can not post a link to the photo I made of it.

Hello!
I've just bought an AS111. Charges perfectly my SGS4 but it doesn't do a thing when I try connecting my SGN3 (the one with the micro-usb 3 connector) to the Philips dock. I know that the micro-usb 3 is backwards compatible but I do believe that the AS111's dock outputs too little power - or something like that, I am no expert.
I was wondering that maybe your experience could be of help to me. What do you think? If so, could you please guide me through the stuff you did to the dock? Thank you!

I want to get a second cable to charge my touch pro while I am at work, can I got and buy any 5-pin mini USB cable or do I have to order a HTC cable?
Standard cable will be fine
I've just looked at the USB cable Expansys sell (http://www.expansys.com/p.aspx?i=166227) but looking at the picture the plug is a differant shape to the socket on my Touch pro. I can't find anywhere that sells a cable that looks like the socket (rectangular with bottom right corner chamfered, I assume everyone is the same). Can anyone point me in the right direction?
You already have answer from ardsar
For charging standard mini-USB cable is ok.
Yes, and what I said was that a standard mini usb has a differant plug. How can I use it if it has a differant plug?
yes it does, but so did the HTC3300, but the charger and data cable use the 'standard' mini usb connector.
I have one (car charger and 'standard' usb cable) and they both fit fine, work fine and charge fine. so no need to worry.
Basically, a normal mini-usb plug will fit in HTCs proprietary socket

Thanks, looks like I need it spelling out for me!
Cheers All
I bought some really cheap retractable cables of ebay. When I got them they didn't work at all. I opened and rewired the micro-usb connector - the cables were connected all wrong, but after a little soldering I think they're correct.
Now the cables are working fine with my Nokia N82, but when I connect them to my Desire and Desire HD my computer won't recognize it as USB devices, only charging.
I've looked at the pinout here http://www.kineteka.com/microusb-b.aspx - should pin 4 be connected to GND to use it with HTC?
Any tips?
I was curious of the pinout, thanks for the link.
As far as wether the pin should be grounded, well... if it's not working ATM ground it and see if it works? Since you're successfully charging the phone you know you connected the +5 correctly, grounding any other pins won't cause damage...
Cheers
P.S. Also sometimes good to check the obvious, did you enable the Mass-Storage option in Android?
I've had similar issues with USB 1.1 ports.
Are you connecting it to a USB 2 port??
I'm looking to mount my phone to the "A" pillar in my car, but I don't want cords running all over the place. I'm looking at doing an install similar to what people do with radar detectors by hooking into the fuse box inside the car (with an adapter like the one found here). This would be just for power. I understand how to wire it up theoretically (don't need to hook up the data wires, just the power and ground). I'm just looking for a mentor to make sure I do it right.
Has anyone ever done something like this using an adapter like the one I've mentioned? And what size fuse did you use for the install so you don't hurt the phone?
On a side note, I'm driving a 2006 VW Jetta, if that helps in any way.

When I bought my car it had some hard wired cable like that, plugged an old phone in to be safe and it didn't charge properly. I scrapped the idea and just got a car deck with double usb and ran the usb to my arm console.

I'm trying to not have cables running everywhere like I currently do. I've already got an aftermarket XM radio next to my radio which uses up a cigarette light adapter already.

What exactly do you need help with? - There are 4 wires in the usb cord. Use red for positive wire but DO NOT connect directly to 12v. USB is 5v so connecting to anything higher WILL fry your phone. You will need to get something that converts 12VDC to 5VDC. Red wire is 5v positive and black is your negative (ground). If you wanna do it cheap and easy, go buy a usb cigarette adapter, take it apart, then take the wires going to the metal connectors and connect them to your power and ground. then just plug in your usb cord and hide the whole thing in the dash.
Hope this helps.

Yeah, I started looking into it and realized that 5V /= 12V. I'm currently looking at using an old cigarette lighter adapters internals and wiring them into one of those fuse adapters (it'll convert the 12V down to 5V), then take the wires and hook them into a USB cable. I've got to do some measurements and all, so I'll respond back with some pictures of when I start the project. Should cost less than $20 and about an hour of time.
Website showing detail
Alright, I have finally done the project (just have to hook it up). This website shows all of the details. I did use an add-a-fuse instead, but it is essentially the same idea. I will be adding it into my car later today.
Thought I would share my experience so no one else repeats this. I bought a micro usb ethernet device so I can hardwire my nexus player. Connected it to nexus player and it did not work. The ethernet device had an extra power cable for it. Thinking it may need more power, I foolishly connected power cable. Now nexus player doesn't even turn on (powerlight off). I'm afraid I may have shorted the motherboard. I was able to open up nexus player using guitar pick....but don't even know what to do. Spent alot of time tinkering with it too. So sad as I am now left with an oversized hockey puck Lesson learned.
Look for black marks or brown you can also take a multimeter and check components you would want to check any smd fuses first then trace back from the USB plug. I don't imagine that killing the whole thing. Does it respond at all?

Did not see any black or brown marks. Unfortunately it does not turn on at all. I'm getting desperate and am thinking of buying a new 12v 1.5 amp adapter. Do you think that may work? Thanks for your input.

I don't think so if hypothetically the Ethernet adaptor delivered voltage to the usb port on the nexus player and now with just hdmi and power plugged in it wont turn on i doubt a new ac adapter will fix anything.
You can check your current adaptor if it is broken by using a multi-meter to see if it is providing 12v.
Can you link the Ethernet adaptor you tried to use? And what ac adaptor you plugged into it.
I can think of a few things that are not what you think they are that have ac adapter sockets. But i cant think of a single Ethernet to usb adapter that takes 12v all the ones i know would be a 5v adapter at most with more running off usb power...
I would look for a replacement nexus player not just the ac adaptor... Check target or walmart first they dropped them down to 20-40 when they got discontinued i wish i had picked up a second one now... i got 2 of the game controllers one for 29 one for 10...

Yeah it is not the ac adapter. I tried an equivalent 12v 1.5amp and it still didn't turn on. When plugged in if I put my ear next to nexus player....I do hear a faint hissing sound, so there is some activity going on. I went out and bought a multi-meter and did what you suggested to check components tracing back to usb. This is all new stuff to me but I found that there was 0 reading on a tiny black rectangular module that has P15 on it. I'm assuming that is the smd fuse. Not even sure where to buy a replacement one. Tried to procure one from old computer board but was unsuccessful. Will search some more online on where to buy one and learn how to solder.
The ethernet I bought was http://www.ebay.com/itm/White-Micro...851881?hash=item567e4840e9:g:QEkAAOSwvt1WRYAO I wasn't thinking and plugged a 12v 1amp into it.
Only nexus player I see being sold is on ebay. I'm being persistent on reviving this one only because I spent alot of time on it already and am stubborn....lol But I will give up when I replace the P15 module and it still doesn't work. If nothing else at least I'm learning...so thank you.
Yes the little thing labled p15 is a fuse im about 80% i think p5 is also a fuse... you should get 0 resistance on them and they should be able to pass current switch the meter to Continuity mode and if the 2 probes are connected it should make a noise put them on either side of the fuses if they dont pass current they are likely blown as for replacements dangerous method would be to replace them with a wire otherwise they should be around .50 cents each from what i could find they are self resetting type so they should reset once any residual voltage is gone.

Hi all,
I am trying to mod my old tf300t and keyboard dock into a dex dock for my note 9. Im not worried about the tablet portion as i can get a lcd controller for the panel. However ive been soldering and desoldering for the last 3 days. I am trying to leverage the docks kb controller and add a usb connection or modify the dock port into a usb.
I have looked at the various pinouts but cannot get the keyboard working.
I dont care about audio or sd card or the extra usb port.
Any help or pointers would be great.
Here is a mockup of the pinouts i have soldered based on the pinouts i found
Ive been trying to test it on an old s7edge incase i wire something wrong. It detects a regular keyboard but when i try this nothing...if i use the wall charger i see that the dock is charging but still nothing at the dock connector. Ive been trying with a usb 2.0 cable. Connected to the d+ d- vcc ( all 3) and multiple grounds and i pinned the sense pin to ground as well.
I have also tried to open the charge cable and solder the usb to the data pins on that both with and without ground. And use a 5v plug and the original asus plug.
The dock port is basically garbage at this point so if i plan to use that i need to use the 2 20 wire connectors and map the individual wires .
I have managed to get the s7edge to detect that something is connected. However i then resoldered the pins to try more as it wasnt working. So i need to go back to the beginning to try again. I believe my issue was due to the otg aspect of the usb. Im using an adapter for the phone but i also tried to wire the connector the same way. Ill take some pictures of it later if i can get it working
So not sure if anyone is following this thread but i have made progress.
I have totally butchered the original 40 pin connector and now am tapping into the 40 individual wires that connect the main board to the connector pcb. I can get my s7edge to detect that the usb connector is attached but it keeps telling me that a high power usb device is attached and that it needs an external power source.... so today i busted out the multimeter and i believe i connected one of the usb host vcc connections to the other vcc connections so i separated this. I also believe that the s7edge has some usbotg voltage issues so im going to test it with an old macbook pro with windows to see what it picks it up as. When i get some more time i will try to trace the other wires there might be something else needed
Maybe
Nice job, I'm not particularly knowlegdable in electronics but I remember there is a battery portion in the dock? Maybe it causes some error during otg?
