Plus, because it features 2000-volt optical isolation, you can protect your PC and other equipment from dangerous spikes and surges on the RS-485/RS-422 network.
Simply plug it into your PC’s USB port using the included USB cable (3-ft.), then configure its DIP switches for 2- or 4-wire operation. The converter will show up as an additional COM port in your PC’s Windows Device Manager.
