    Ok. By this you mean look at your thread somewhere? It's just a couple threads down? Never mind I'll go through your profile and find it.

    By this I'm a little confused. My understanding is that the Galaxy Tab is a Multimedia tab that passes through with an HDMI Port, but also has a 30 pin port to it for the Samsung 30 pin connector to usb cable. I'm not sure why that would make any difference as far as if it would be on or off. But I just don't understand that stuff.

    I'll check out the forums, but the problem is, I don't know what i'm looking for to say what's better or worse or whatnot. That's why I was posting on here.

    Who is xda-developers btw? Is that on here or somewhere else?

    The reason I'm going through all this is to get an analog signal, preferably a strong one, and then you talked about the optical signal. I only have, with the Galaxy 10.1, an HDMI output via that multimedia tab, or a usb output to work with. There's no other outputs on it. They aren't making an adapter yet to do a whole lot, like Apple is right now. If I could get a composite adapter that has composite RCA,s and a 30 pin connector, I'd be happy about that even though I'd still have to find a way to charge it all. But they don't make one yet.

    You must have analog input each time you turn on the processor? it sounds really weird for it to be true..
    Yes you need an analog signal to set up the Bit One, but once it's set up you can use the optical input if you want or the analog input. But you have to have the analog input to "set up" the Bit One. Don't have to have it every time you turn it one, just when you do your original set up.

    Come back with the info and we will figure out the best way to achieve what you want
    There isn't a usb output on this tablet. it's a 30 pin connector for Samsung, and the multimedia tab plugs into it with that 30 pin connector. The multimedia tab itself has an HDMI port out, and another 30pin connector (same as it plugs into) for the charger or whatever. So I'm not sure about the USB-HOST stuff and how or what to check out. There isn't a 3.5mm jack on it, that I can recall. Actually there is one on the dock, but I'm not gonna use that anyway.

    This looks promising! I like that. So how do you have that hooked up? Do you power several items via usb? I would be very interested to see how this hooks up.

    So my basic needs are this. I need an analog audio signal from the Galaxy 10.1 Tablet to the Bit One, preferably a good one. I need a video signal from the Galaxy 10.1 to the headrest monitors. I need to power the Galaxy 10.1 while it's in the dock in the car. That's about it. Nothing more nothing less. Would i like optical, of course who wouldn't. Do I need it, no I don't. So until I can figure out how to get it, then I'm not going to worry about it, cause it's not that great a deal to me. Yes it will sound 100xs better, I get that. But if I don't have it, I'm not gonna cry over it.

    Those are my basic needs. Now I'm probably not gonna get back to this for a few days, I'm going camping and since the mods have to approve all my posts, this will probably not post till this afternoon and I'll most likely be gone.

    I wish I knew more about this part of the electronic world, but I just don't. That's why I'm trying to get help. I don't mind researching but sometimes doing that in this part of electronics, can just absolutely burn my head till my brain explodes and then in the end, I get nothing out of it. Most of the time. I'm not dumb, at least I don't think so but you can reserve judgement till a later point if you want to, I just am not familiar with these types of parts.

    Thanks for your time thus far, hopefully we can figure out the best way to make this happen then I can build it and we can all share in the joy of it! Thanks!

    Sorry , Here it is :

    Who is xda-developers btw? Is that on here or somewhere else?
    I didn't say it won't work.. I just said you need to check that out
    Each device has its own abilities , and acts differently according to what the manufacturer designed and the developers community achieved..

    XDA-Developers , Is where 99% of current phone/tablet hacking starts
    Here is a quick link to the galaxy forums : http://forum.xda-developers.com/forumdisplay.php?f=752
    I suggest that if you are planning to install a tablet in your car that you would know how to handle it..

    The reason I'm going through all this is to get an analog signal, preferably a strong one, and then you talked about the optical signal. I only have, with the Galaxy 10.1, an HDMI output via that multimedia tab, or a usb output to work with. There's no other outputs on it.

There isn't a 3.5mm jack on it, that I can recall. Actually there is one on the dock, but I'm not gonna use that anyway.
    First according to specs , there is a 3.5mm connector ( Anyway , I haven't seen a device out there without so check again.. )
    A simple 3.5mm to 2 rca cable will do the work for analog , As you said , You just need it once..

    The USB-HOST ( OTG = On The Go ) stuff probably connects to the 30-pin connector with a special cable ( I'm sure the info is on XDA )
    When you are on XDA search for the devices that known to work , devices that don't , etc..
    If the developers enabled USB AUDIO then you can get audio from the device using the stuff we mentioned earlier ( USB DAC for analog / USB to SPDIF for digital )

    This and the headphone out , Should cover the audio part of your install


    Talking about overkill's
    I Think it would be best to invest in a good solid 5v power supply than in a hub..
    Unless you are planning a din install of course..

    This looks promising! I like that. So how do you have that hooked up? Do you power several items via usb? I would be very interested to see how this hooks up.
    The Nook can charge and act like a usb-host , Simultaneously
    I already successfully hooked 4-5 devices at the same time and that worked great
    I plugged 3 mouses and even moved them together ( it was funny to see 3 cursors jump around )
    My USB-DAC , flash drive , card reader all worked as expected too
    According to usb port specs - It should connect 127 Devices per port as long as power is not the issue , so no worries there..
    Also , Only the hub needs to be powered through it's own power connector - All of the devices ( Including the nook ) get the current needed from there

    Here Is a video of a guy with a Nexus One ( The first Android phone to get usb-host support if I'm not mistaken ) , Using A-LOT! of devices at the same time


    Everything that support linux can be hooked up eventually - The question is if the driver has been ported to Android.

    So my basic needs are this. I need an analog audio signal from the Galaxy 10.1 Tablet to the Bit One, preferably a good one. I need a video signal from the Galaxy 10.1 to the headrest monitors. I need to power the Galaxy 10.1 while it's in the dock in the car. That's about it. Nothing more nothing less. Would i like optical, of course who wouldn't. Do I need it, no I don't.

    I get your basic needs and I think we covered the audio part
    As for video , you need to check if usb-host can work with the HDMI out and that no-one cancel's another
    Once you do that you have 2 options from my point of view :
    1.usb vga ( if supported ) + vga to composite converter box ( available at low prices online/ebay )
    2.hdmi to composite with whatever converters you decide to get..

    I don't see any other way to get composite out of the device..

    Have fun in your vacation , And your welcome

    Wow lots of great info there man. I'll start looking into and researching it. Thanks so much for the links and the info to look at. Gives me a place to start looking further.

    Vacation was great. Back to reality now, boo!

    Well I don't know what happened there, since it doesn't show up right away, I'm not sure if this will be redundant or not.

    I think I've found a way to get it all in one module using the Galaxy Tab Media Adapter (HDMI)

    This is the Gefen GTV-HDMI-2-COMPSVIDS. This unit takes an HDMI input, and can turn it into an all active composite video and audio output, s video output, and a digital output. The one that I found on another site has a toslink optical output on it instead of the digital coax output like this one has, so I'm not sure if they just changed that or what. Either way, the Bit One will take it. Here's a wiring diagram for it: Wiring Diagram, and the instruction manual..

    The next one I found is an Octava HDDA11V13. Again this does everything in one unit, but I still have to convert the video signal on this one cause it goes in HDMI and comes out HDMI. But I think what I can do is an HDMI to VGA adapter, then a VGA to composite adapter. If that works that will give me the toslink optical signal for the Bit One, as well as the Analog signal to the Bit One and the Video signal to the monitors all in one box!

    Either of these boxes or converters will allow the 30 pin port to usb (cable that comes with it) to be used strictly for the charging of the tablet. I'm gonna do a couple of drawing schematics to better portray my thoughts. I'm gonna go post this on XDADevelopers.com too and see what I can get out of them over there.

    I'll post the drawings later. Thanks!

    Ok so I got the wire diagrams done. MS Paint, gotta love it right! HA!

    First one with the Gefen Converter:


    And the second one with the Octava Converter


    Anyone object to the function of either of these?

    Ok so I just got an email back from Gefen and they said the one with the Toslink is incorrect. It is in fact a coax digital signal. So he suggested to get a toslink optical signal I add in this Gefen GTV-DIGAUDT-141 and that will give me toslink. Although if i have a coax digital signal I guess that should be good enough on the bit one. I'll talk with my audio guys about that.

    Ok I just learned another trick over at XDA. The old samsung galaxy 7 docking station has an HDMI output on the dock itself, no adapter needed. The 10.1 dock is the one that needs the adapter for the HDMI. The plastic dock pieces, or frames if you will, apparently just clip off. You can take the back of the Dock from the SG7 and clip on the dock for the SG10.1. NO ADAPTER NEEDED! WOO!!

    Ok so I edited the picture above to post up the correct module. This is the module with the converter to go from digital coax to toslink optical.

    Looks fine
    Let us know how it worked out eventually and how is the sound quality

    Will do. It'll be a while but I'll post up the build anyway when it happens. Thanks for all your help!
