  • which do you want to use RFID Reader?
    Is device support RS485 or RS232? How many reader are connect to bus?
    I think, you want to connect pc to device, and control the device with vs2005 software.
    is your pc support RS232 port connectors? if not support, you should have usb to RS485 cable(device support RS485) or usb to RS232 cable(device support RS232). Some devices are support multiple communication protocols. yours which one?

    rs232-rs485 converter only convert  signal level,  do you know your reader data protocol?
