![]() In Windows Vista, click Start -> Control Panel -> System and Maintenance -> Device Manager In Windows 7, click Start -> Control Panel -> Hardware and Sound -> Device Manager In Windows 8, swipe up from the bottom, or right-click anywhere on the desktop and choose "All Apps" -> swipe or scroll right and choose "Control Panel" (under Windows System section) -> Hardware and Sound -> Device Manager In Windows 11, Windows 10 & Windows 8.1, right-click the Start menu and select Device Manager In Windows, use a built-in utility called Device Manager, which allows you to see all of the devices recognized by your system, and the drivers associated with them. Once you have downloaded your new driver, you'll need to install it. Most major device manufacturers update their drivers regularly. To find the newest driver, you may need to visit the Cisco website. It is a software utility which automatically finds and downloads the right driver. Tech Tip: If you are having trouble deciding which is the right driver, try the Cisco Driver Update Utility. In the results, choose the best match for your PC and operating system. Enter Cisco USB to Serial Adapter into the search box above and then submit. If the driver listed is not the right version or operating system, search our driver archive for the correct version. After you complete your download, move on to Step 2. To get the USB to Serial Adapter driver, click the green download button above.

The FT232R is available in Pb-free (RoHS compliant) compact 28-Lead SSOP and QFN-32 packages. A unique number (the FTDIChip-ID™) is burnt into the device during manufacture and is readable over USB, thus forming the basis of a security dongle which can be used to protect customer application software from being copied. The internally generated clock (6MHz, 12MHz, 24MHz, and 48MHz) can be brought out of the device and used to drive a microcontroller or external logic. The FT232R adds two new functions compared with its predecessors, effectively making it a “3-in-1” chip for some application areas. USB to serial designs using the FT232R have been further simplified by fully integrating the external EEPROM, clock circuit and USB resistors onto the device. In addition, asynchronous and synchronous bit bang interface modes are available. The FT232R is a USB to serial UART interface with optional clock generator output, and the new FTDIChip-ID™ security dongle feature. The FT232R device is added to FTDI’s range of USB UART interface Integrated Circuit Devices. ![]()
