Description:

The S107USB is designed to accept a single USB input and give a single, isolated, RS485 output. The S107USB features a high-speed 250 Kbps transmission rate and draws it power from the PC's USB port eliminating the need to wire an external power supply.
It is easily configurable, once the drivers installed just plug the converter into an available USB port and the device will show up as an additional COM port in the Windows Device Manager. Configured as an additional COM port, the converter is now compatible with your Windows applications.
