| Mar 4, 2016 at 23:52 | comment | added | Transistor | @Yatekii: My answer only works on parallel connected devices. It turns out that you are series connecting the devices so your DC line will only reach the first panel. You need to edit your question and add the full setup and specifications if you need additional help. | |

| Mar 3, 2016 at 23:08 | comment | added | user57037 | FSK is also a possibility (maybe you consider FSK to be a type of PSK). If you organize your system so that it always changes frequency at zero crossings, the phase will be continuous, which is a good thing. | |
| Mar 3, 2016 at 22:55 | comment | added | Yatekii | I answered your followup question in the edit. Satisfactory I hope :) | |
| Mar 3, 2016 at 22:36 | comment | added | Transistor | How much data do you need to transmit and how much pain would you suffer if there was an error? i.e., Are you just switching stuff like lights on and off remotely every once in a while or are you building an autonomous fly-by-wire car that will carry you and your family in high-speed traffic? Edit your original question with the additional info - bits per second, or whatever - and you might get a better response than mine. Also indicate what level of understanding you have of serial data transmission such as RS232 or RS485 because your data will be similar. | |
| Mar 3, 2016 at 22:22 | comment | added | Yatekii | Sorry for the long followup that doesn't even fit into 600 chars ... I hope that's ok! Would you rather do FM or PSK than AM? I really don't need a high data rate but I need kind of a high range (40-50m). That's kind of the thing that troubles me most atm. How do I determine the range I can get. Because I know of SPI and TWI that really suck on high ranges :) | |
| Mar 3, 2016 at 22:22 | comment | added | Yatekii | Wow, thanks a whole lot! This answer really explains a lot and helps me very much. Not to mention the awesome drawing! Time is really no problem and I am very willing to read a lot too. This all makes sense to me but one thing:How am I supposed to actually put data. I mean, I can do this AM or FM I guess. There is also PSK. AM is the easiest but I am concerned because I do not know what exact VDC I have. It could change over time (with very low frequency!!) so I would need a reference voltage I guess. I thought of maybe a cap that buffers the level whilst the transmission goes on? | |
