Hi, Have anybody succeed with the power line communication over a dc line of about 12 -36 V. If so, could you please tell me the IC which you have used. Also i have given my planned system here where master will query and receives the data from the addressed slaves (number of slaves around 10 to 15) (...)
Hi, Did anybody use the infrasys power line communication IC over dc line. I am using this IC and facing some issues. When i am using a single master and single slave,the working is good. But when i include another slave, communication is not good. Neither slave 1 and slave 2 not working (...)
I don't think that it works without modulation, similar to PLC (power line communication) techniques.
Hi, Is it possible to communicate over dc power line of 12V as a master slave rs 485 communication. Is there any specific IC's available. If possible please tell me how to do that? Thanks, Murugesh
What communication scheme are you planning to use? What modulation? The speed is severely depending on the modulation scheme, and if there are regulations you need to consider, the bandwidth of the communication signal needs to be mentioned. Depending on the hardware, the more advanced modulation you may use, but if you're allowed to use a large ba
This chip is intended for AC communication. I don't think it will work over DC lines since you need to couple a signal through a transformer. You'll need a different approach for DC communication -- perhaps 1-wire communications. Our company uses a technique of modulating the DC power (...)
Hi Punkaj, I think you are talking about power line communication (PLC) used in Building-Home Automation systems (BACnet). Search in EDAboard for DC-Bus or PLC. Regards. Pcup
anyone have success with power line communication over a DC bus? or know of any research papers on the subject? anyone selling such a product? Mr.Cool
Hi, has someone any kind of experience or information about implementing a communication over a dc power bus. In particular that dc bus is the output (700V) of various step-up machines that are in parallel elevating the voltage of independent photovoltaic strings in order to be the input of a three-phase inverter to be the (...)
just an easy idea: On your power supply side you need a resistor and a differential amp to measure the current through the supply lines. On the ?C side you connect a port pin to a transistor that will draw some current from the power lines. thats all for unidirectional communication. More (...)
