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?
no i meant using rs485 for data over some power line could be a problem.
usually single-ended signal would be coupled in & out from the power line using capacitive coupling, after possibly being modulated onto some carrier freq.
the rs485 is a differential signal meant for directly driving a long wire pair, so i'm not sure how you would do this.
I did not mean to have a rs485 over dc line.
I mean to have a communication between a master and some slaves similar to rs485 communication.
So could you tell me how to communicate over a 12V dc line between devices. If you know any ic or circuit please share..
