Advantech BB-485USB9F

Universal Serial Bus (USB) has become the connectivity workhorse of today’s PCs, replacing the familiar serial port. However, many commercial and industrial devices still use the RS-485 interface. To connect these devices to modern PCs, you need a simple and reliable conversion solution. The 485USB9F-2W-x and 485USB9F-4W-x offer this solution in a space saving, USB port powered package.

Simply install the drivers and plug the converter into an available USB port on your computer or USB hub. The device will show up as an additional COM port in the Windows Device Manager which is fully compatible with your Windows applications. Choose the 485USB9F-2W-x for RS-485 2-wire applications or the 485USB9F-4W-x for RS-485 4-wire applications. A one meter USB cable is included. Locked serial number versions are also available.
