With the widespread adoption of USB, most computers sold now do not have an RS-232 port. Therefore, to connect an RS-232 device to a computer, you need to use a USB to RS-232 adapter, such as our RPC-RS232-UF-3M converter.
While USB to RS-232 adapters perform a necessary function, they do have some limitations. The most common problem that our customers encounter with a USB to RS-232 adapter is getting the proper driver installed. The driver must correspond to the chip inside the cable—not to the manufacturer of the cable. Maxton RPC-RS232-UF-3M cable is using an FTDI chip (part number 17394). We chose this cable because it uses a chip that has a certified driver available on Windows Update. If the driver for your adapter is not automatically installed or cannot be installed from a CD, you will need to identify the chip in your cable and locate the driver on the Internet.
