anhnha Posted April 28, 2012 Report Share Posted April 28, 2012 I used MAX232CPE without any capacitor and power supply is tied.Then I tied the TX of comm port to one pins the the RX of the comm port to another pins of MAX232.Next transmit data to comm port.But i am confusing that I can receive data exactly when TX and RX is tied any pin of MAX232I have tested MAX232 it is good.Would you tell me is this is true?Or there something wrong here?
