Quick Tip!

The USB to RS232 adapter - Generally

For successful data communication when you use a USB to RS232 adapter you must make sure to install the drivers properly. This is probably the most important step in making the serial adapter work without problems. Installing the drivers for most USB to RS232 converters is easy if you carefully follow the installation instructions. Usually you simply need to plug in the adapter and then point the Windows Hardware installer to the folder containing the drivers. The drivers can be downloaded and saved locally on your computer. Once the Windows hardware installer have finished the driver installation the USB to RS232 adapter will usually be ready to use, however some drivers require you to reboot your computer first. Check in Windows Device Manager if the virtual COM port has been created and is working properly.

We have many models of converters and adapters, check our large selection of USB to serial adapter products to make sure to find the right one for your project.
