Topic: TxD TTL communication to the Arduino board (Read 745 times) previous topic - next topic


Hi there,

I just received a RFID reader from TagStar that offers both TTL as RS232 output. I wonder if there is a way to simply connect the TxD TTL output to the Arduino so I could get all the data from the reader directly into my arduino board. The reader is in auto polling mode when connected to the TTL output so I dont have to send anything to the reader in order to poll,

any help is appreciated a lot
