EX-Link Cable don't work
EX-Link Cable don't work
I have an ex-link cable built with VGA connector to the instructions in the wiki, for that I have used a CA-42, it unfortunately does not work on my UE46D6510. The debug mode is enabled and the cable I have checked several times, and the function of the cable is ok (bridge between rx and tx and tested with a terminal program) Can it be that my TV has a different pin assignment or is the service connector possibly the 3.5 stereo plug?
Re: EX-Link Cable don't work
I can confirm for your tv model everything is ok according wiki. If you use vga-to-vga cable, remove it and connect your exlink directly to TV`s vga port.

Re: EX-Link Cable don't work
No, I don't use a vga - vga cable, i connected the cable directly. I once measured with a voltmeter to pin 4 of the Adapter (TX of the adapter) 3.5 V are applied, to pin 11 of the TV (TX of the TV) no Voltage ist on.
I thought that the TX is always a voltage is applied? If yes then the Pin 11 of the TV could not be the TX. I have also measured with an oscilloscope on the TX of the adapter to make absolutely sure that this is the right line. Now I do not know why the the terminal program don't get any output. Could it be that the Hospitality mode hack the serial interface disabled?

Re: EX-Link Cable don't work
Stupid question , but did try to swap TX and RX lines ?
On the tv that have a VGA input the Ex link is wired to it . otherwise you should find a "service" jack socket

Re: EX-Link Cable don't work
Yes, I have tried to swap RX and TX, but I testet the TX of the Adapter with an Oscilloscope and a Terminal Programm, then I have conneectet this line with pin 4 of the VGA Connector (RX of the TV). I'm an electrician, I can even make mistakes but I'm not a beginner
The pin 12 of the TV have 5 Volts, could it not be that this is the TX pin of the TV? Because i don't understand why on pin 11 no Voltage is present.

Re: EX-Link Cable don't work
ah right , sorry BTW i'm a technician in electronics and i keep on swapping TX and RX lines
If my memory's correct there's no pull up resistor on RX pin.
So the problem is that you get no data from the TV ?

Re: EX-Link Cable don't work
Yes, thats right, no data from TV is shown in the Terminal (putty), I have done everything as it was in the wiki for ex-link cable. No pull up resistor from RX means TX from the TV's point of view?
Re: EX-Link Cable don't work
the pin 4 ( TX on the TV side ) has a pull up resistor to the 3.3v line , but the pin 11 does'nt. Anyway data is always present on pin 4 at startup. Maybe is it a level compatibility problem ?
Re: EX-Link Cable don't work
Shame on me, the Problem was realy swapped TX and RX lines, I had tested several adapters and so I came a bit confused . I not only can make mistakes, I make them really.
Now the Adapter works very well. Thanks a lot for Help
