i want little help plz help me.
i am using transmitter tlp434A and receiver rlp434 with AT89c51 at receiver's and at transmitter's end as well .i want to transmit (just testing) digit 18 (converted to ASCII,from binary).when i conect the TXD pin of MCU (at transmitter's end) with the Rxd pin of mcu (at receiver's end).it perfectly transmit didgit 18 and is displayed on lcd perfectly but when i tranmit it by using tlp434 with rlp434 receiver,so digit is not displayed on lcd but i can see only cursor:-(
note tht i connected the txd of mcu to the data in of transmitter directly,at transmitter's end and the data out (digital),of receiver ,i connected to mcu's rxd pin at receiver's end.
kindly help me
