Hi All, Can anybody mention what is the difference for the transponder and transducers. Most of the times i could see that these names are interchanged. Is it correct? From my understanding it seems like transceiver is transmitter+ receiver and transponder is doing the same thing depends on the response from a master device/command. Please help me!!!
