The tenda I used is this one Tenda CPL P200 kit.

I can post the wiring if you need it.

Would be nice if you add it, for future reference by other people.

OK...

So... The Tenda P200 module is a powerline adapter for transmitting ethernet signal through the home electrical grid. By opening this module you will be able to separate the AC side from the modulator module by just separating the two (they are connected with some headers and thats all. Its really simple to separate the two modules.

The modules that we are interested are two modules like this one:
We can ignore the LED lights if we want... I would suggest to connect some LEDs lights to the LED pins so to know whta its going on with the tenda. (LEDs light must have a current limiting resistor).
The wiring of the tenda Is shown in the image below:
I also analized the output so to understand how it modulates the signal. This system should allow a 200meter range communication with a twisted pair wire.

This is the final result with a 3D printed case and a USB 5V converter to power the module.
