pikachuX WROTE:Could it possible to link my rfid DB9 to (UART to RS232 Converter),Then the UART will transmit the Tx signal goes to Rx(out) in Max232.After that the Max232 transmit the Rx(in) to it's DB9 (female) at pin 3.lastly,The (usb to db9-male conveter) which db9 (male) will connect the db9 (female) in Max232 and usb will connect to usb port at Pc.
Am i correct?
I have try this, RFID DB9 convert to UART using the schematic below, then RC7_A connect to (RX) UART to USB converter, and then connect to PC. You can check data using HyperTerminal.
My method: RFID MAX232 (DB9) > UART > USB > PC
Your method: RFID MAX232 (DB9) > UART > MAX232 > USB > PC
