3 years ago Shalom198 and I are discussing this via e-mail. We'll update the thread in a clean way that shows issue + solution once complete. Now I'm trying to understand his setup since I can't physically see it. I'm also working on setting up a 220VAC PLM master and slave test to verify that communications are still successful at 220VAC.

3 years ago Shalom,
I understand you're using 220VAC @ 50 Hz source. Please provide pictures or diagrams to describe the setup to me in detail. I need know all the components involved and how they are interconnected. I have no idea what your setup looks like, I need this info in order to troubleshoot it and provide a solution.

3 years ago Hi Thank you very much for the desire I very much appreciate it My situation today is that on the power line of the 220V there is no communication I got a scoop device, and found that there is noise in the line (I measured at the point of the TX) even when the TDA does not transmit, the noise is about KHZ 70-90, 200-300MV There seems to be some resonance I do not know how to use the scoop device professionally, I thought to measure the power line itself to see if the noise is in the power line regardless of the PLC or the PLC creates it But I do not know how to measure the power line using the scoop device, I am afraid to burn it

3 years ago Hello again I discovered something interesting, I replaced the serial capacitor at the entrance (C10) Instead of 47NF I put 470NF (I saw that this is the value in the APLICATION NOTE) I replaced only one module, and then an interesting thing happened, the second module read the communication correctly, however when I also replaced the capacitor in the second module, again there was a complete lack of communication

2 years ago Shalom,
Restore the demo/breakout boards with the original 47nF CAP and swap out XTAL, X1, with a 7.3728 MHz 18pF standard crystal like MPN: ABL-7.3728MHZ-B2. This adjusts the PLM carrier frequency to 115kHz which matches the resonant frequency of the tuning circuitry. I strongly believe the boards I sent you have an 8MHz crystal which sets the PLM carrier frequency to 125kHz.

2 years ago , I switched to 7.3728 MHz, but it did not work , the same problem. Currently the system only works if I put an autotransformer (220V > 110V ) between the mains of electricity and the line on which I put the POWERLINE
Thank you very much for everything, hoping we can find a solution

the module works fine with 110V but dosnt works with 220V what wrong ??
