The RS485 to USB communication cable is a device for interface conversion. It can convert data from the RS485 protocol to the USB protocol, and vice versa. In this way, a computer can communicate with devices that support the RS485 protocol, such as a 51.2V 100AH Lithium Iron Phosphate (LiFePO4) battery 3U, via the USB interface. This allows for operations like connecting to a host computer or SolarAssistant, reading battery data, and updating battery firmware.
