Connect legacy RS-422/485 devices to a USB port and get 2000V isolation from voltage spikes and ground loops. Universal Serial Bus (USB) has become the connectivity workhorse of today?s PCs, replacing the familiar serial ports. However, many commercial and industrial devices still use the RS-232 interface. To connect these devices to modern PCs and provide protection from electrical transients, you need a simple and reliable conversion solution. The USOPTL4DR offers this solution. Simply plug the converter into an available USB port on your computer or USB hub and install the drivers supplied on CD ROM. The device will show up as additional COM ports in the Windows Device Manager which are fully compatible with your Windows applications. A one meter USB cable is included.
