Connect RS-422 and RS-485 (2-wire and 4-wire) devices to a USB port and gain 2000 V RMS 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-422/485 interface. To connect these devices to modern PCs and provide protection from electrical transients, you need a simple and reliable conversion solution.

The USOPTL4-2P offers this solution and is ideal for applications requiring long-range or multi-drop capabilities. It features include a high retention USB interface, removable terminal blocks on the serial side and LEDs to indicate data flow.

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 port in the Windows Device Manager, which is fully compatible with your Windows applications. A one meter USB cable is included.
