I need to build an RS485 tx/rx including 1 transimater and 1 receiver
the transimitter have its own power supply and the receiver is at 100 meter from the Tx the Questions are:
1--how to use data line between the Tx and Rx to carry both data and
power?
2-- is it possible to use data line as power source for thr Rx i.e by using a bridge rectifier at the receiving end on the data line + a rectifier capacitor
then connecting them to supply pins of the Rx
if you have any idea or circuit or if you find it impossible plz reply me
bye.
