The FT232R USB driver is a bit of a complicated install. The screenshots below will give you direction with regards to installing the driver the correct way. This means that you first have to uninstall the driver, disconnect from the internet and then install the driver again. The FT232R USB drivers below need to be extracted to an area on your computer you can find.
FT232R USB UART Driver
Download the driver file and extract it to your hard driver where you can find it
You first need to uninstall the incorrect drivers on your computer. In Windows, go to Control Panel then to Device Manager
Now press the delete button on your computer and it will ask for confirmation.
Collapse the Ports menu and now click on the USB controller at the bottom of the list.
Now you need to uninstall the existing USB Serial Convertor.
Disconnect the USB cable from your PC to KMX1 or KMX2
reconnect the USB cable from your PC to KMX1 or KMX2
A new yellow flagged item will appear FT232R USB UART
Right Click on FT232R USB UART
Select Update Driver Software
Now you need to find where you extracted the drivers from the file you downloaded above and point the software to the directory.
The driver software for USB Serial Converter has been installed
The USB Serial Convertor is now installed. Next you have to install the port. If you are old enough to remember software modems then you will recall that it was done in the same manner.
The yellow flagged item will have changed name to USB Serial Port
Right Click on USB Serial Port
Select Update Driver Software
The driver software for the Port is in the same directory where you had the other drivers which you had just installed.
The Serial Port will now install and that will be the final installation. There should be no yellow flags any more.

What is a UART driver?
The UART is a universal asynchronous receiver-transmitter and it is computer hardware used in asynchronous serial communication where the data format and transmission speeds can be configured. The signaling on a UART is done using levels and methods handled by a driver circuit outside of the UART.
What is the ft232r USB UART driver?
The ft232r USB UART device is used in many devices which uses asynchronous serial communication. You can download the ft232r USB UART driver by clicking on the driver above. Ensure that you have an ft232r device for the UART driver to be recognised. See troubleshooting the ft232r on this website.
What is difference between rs232 and UART?
The difference between the rs232 and UART is that the rs232 is a asynchronous serial communication protocol used by a UART device. Think of the UART as the computer while the rs232 is the software on the computer. The rs232 protocol runs over UART hardware.
Is rs232 digital or analog?
The rs232 is analog. The rs232 uses voltages to communicate.
Why is rs232 still used?
USB is standard today however that was not always so. The rs232 was used on older printers and still used today. Most rs232 devices today are used on scientific equipment and on mainly industrial sensors and remote equipment. It is much easier to use the rs232 on low voltage systems.
What is the difference between rs232 and rs232c?
The difference between the two standards is that the rs232c version is much newer. The rs232c uses +/- 5 voltage compared to the older rs232 which uses +/- 25 voltage. This is the major difference between the two standards
