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 serial interfaces. To connect these devices to modern PCs, you need a simple and reliable conversion solution. <br /> <br /> The BB-USOPTL4DR series offers this solution. Specifically designed for industrial applications, they offer 3000V optical isolation with 15 KV ESD protection. The slim-line DIN rail mountable enclosure has a small footprint and, since it draws power from your computer’s USB bus, an additional power supply is not required. 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 an additional COM port in the Windows Device Manager which is fully compatible with your Windows applications.
