 Bigger Bigger  Smaller Smaller  Reset Reset

Hi, i'm new to Arduino and trying to build a project that connect RFID reader to rs232 to USB converter and then to the USB socket. From the USB socket have 4 wire that will connect to Arduino, red wire for power, black wire for GND, green and white wire for D+/D-. The things that i don't understand is that knid of data type will send to Arduino from the RFID reader. Also the green and white wire which one is RX and TX.

Thank you all very much, all help is appreciated.

The solution you're proposing is very complex, and I don't think you have any idea of the complexity yet. A far simpler solution would be to use an RS232-to-TTL converter to convert the RS232 signaling to TTL levels and then connect that to an Arduino serial port.

Well, you need to be prepared to deal with a considerable amount of complexity then - and I doubt you have any idea just how much extra work that is going to cause you.
