Touch Pro Video Cable - Build Your Own

I will post a tutorial now on how to build you own cable and what you will need.

1) HTC Audio 2.5mm/USB Splitter Cable can be found here http://accessoryone.com/htc-utstarco...s-pr-5594.html
these also came with the 6800 and 6900.
2) A standard RCA cable cut in half

Steps to Build your cable

1) Start off by striping back the wires from RCA cable and from the 2.5mm side of the adapter cut off the end you wont need it. DO not cut off the metal shielding from the cable just peel it back.

2) Remove the no.4 pin from the ext-usb end. I will provide a pic to show which pin is no4. This will allow the phone to see the adapter as a video adapter instead of a headset. I used a thumb tack to lift the pin and a small set of tweezers to remove it.

3) Now the fun part. The wires on the 2.5mm adpater are RED,GREEN,BLACK,BLUE,WHITE,YELLOW - You will not need the yellow wire so cut it off.

4) Heres how to build the cable connect.

WHITE - Positive for VIDEO
BLUE - Negative for VIDEO
BLACK - Positive AUDIO Left
GREEN - Positive AUDIO Right
RED - Connect both Negatives for audio to this wire then ground this to the Shielding ( I noticed a little ground noise in the audio if i didnt connect the audio ground to the shielding )

Pics are Below i know it sounds confusing but it really isnt.

Re: Touch Pro Video Cable

sweet i think I should have stuff lying around to try it out. funny thing is I threw away RCA cables along time ago. What I do have is a RCA cable for my PS3... what other use do you have for this cable other than cutting it up ?

Re: Touch Pro Video Cable - Build Your Own

Wish I wouldn't have included that splitter cable when I sold my Mogul. Tried to do the mod with the headphones that came with the TP because I still have the nicer set that came with the Mogul. Unfortunately, I couldn't get pin 4 out.

For those thinking of using the TP headphones for the cable, I wouldn't suggest it. It's got those weak headphone like wires in it. It doesn't have the nice insulated wires like in pzztgotbagz's pics. After opening it up, my plan was to use its one insulated wire (white) which should have been the Video + and the gold wire wrapped around it which I believe was the Video -. I was going to skip the audio all together.

For those interested, there's also a discussion on this topic over at XDA - LINK

Re: Touch Pro Video Cable - Build Your Own

Perhaps we need a single sticky thread containing all the methods we currently have for building the TV-out cable.

There are currently three good methods, let us know if you have another easy method. If not, then which one you should use depends on what parts you are starting out with.

http://forum.xda-developers.com/show...5&postcount=19
This first one is fairly clean once finished but might be finicky as the cable must be plugged in at a certain rotation. Required HTC part came with the TP.

TV-Out Blue Flicker and Cable Construction
This second method requires two HTC parts, one each from the TP and Titan.

Touch Pro Video Cable - Build Your Own
This method from this thread requires a single HTC part from the Titan but once finished with electricians tape would be the least bulky of all cables. This should also be the easiest to construct but will be very finicky if the wires are improperly insulated with insulating tape.

Absorbed all that info into the TP essentials thread.

Re: Touch Pro Video Cable - Build Your Own

Just a heads up on this....

I own a cable manufacturing company. Although, we don't typically build cables with USB, we are extremely experienced with making audio/video cables (mostly for military/professional applications).

Since I had an old mogul connector available, I thought we would go ahead and give it a try to determine how long it would take to manufacture as I'm considering offering this as a product.

Everything in these directions is spot on and very easy to complete except for the removal of pin 4 from the external USB. We had a VERY difficult time removing this PIN without damaging the connector and this was using proper tools, magnifying glasses, etc.

If you are going to make this cable, it definetely works, just be aware that you will likely have problems removing the pin and there is a very good chance you will destroy the connector in the process.

Just my .02 cents

Re: Touch Pro Video Cable - Build Your Own

Thanks, took me an hour, but I got it.

Oh, I had a problem removing the pin as well.

Those who are having trouble with that: what I did was get it out of its nook with a safety pin, then I took a small blade just to use it to move the pin back and forth inside the little connector. After about 5 minutes, the pin broke, and no damage to any of the other pins! You could use anything else that you can fit inside the usb connector that would be flat enough to move the pin. I tried with the safety pin, but since it was round, it would keep slipping by the 4pin.
