i just buy the component, TF-Tx-315 and TF-Rx315, but i testing the output of the Rx-315 whenever i given 5v input to data pin of TF-Tx-315, the output of TX-Rx-315 never give me back 5V, and in normal state it still got output 1.7v. why ? how can it produce 5v from output of receiver whenever i give input 5v to transmistter?
