In-Line USB Converter USOPTL4

B+B SmartWorx's USOPTL4 and USPTL4 are USB-to-one-port RS-422/485 converters. Supporting two-wire RS-485 or four-wire RS-422/485 communications, these devices are great for applications requiring long-range or multi-drop capabilities. Both models use pluggable terminal blocks on the RS-422/485 side. Two LEDs indicate data transmit or receive. Model USOPTL4 includes circuitry with 2000 V isolation protection against ground loops and voltage spikes. Both products draw power from the USB port so no power supply is required.

Simply install the drivers supplied on CD-ROM and plug the converter into an available USB port on a computer or USB hub. The device show up as an additional COM port in the Windows Device Manager and is compatible with Windows applications.

USBs have become the connectivity workhorse of today's PCs, replacing classic serial ports, but many commercial and industrial devices still use RS-422/485 interfaces. To connect these devices to modern PCs, robust and reliable conversion solutions are needed. USB ports are becoming more common on commercial and industrial equipment such as point-of-sale peripherals, medical devices, scientific instrumentation, laboratory equipment, and other devices or in environments where surges, spikes, and ground loops are likely to occur.
