USB-RS485 converter for accessing the RS485 bus.


  The USB-RS485 converter is used to connect sensors with an RS485 interface to a computer via a standard USB interface. Using the converter, the RS485 interface is converted to USB. It is a converter used for service and programming purposes. Most often, the converter is used to set the addresses of sensors communicating with the ModBus protocol. The converter has removable screw terminal blocks, through which the sensors are connected to the converter.
