Dynamic platforms Stabilized gimbals Spatial positioning

Data is transmitted as a standard 8-byte UART frame (0x55 0xAA header, function code, four data bytes, checksum); distance is returned as the value ×10 for a one-decimal reading. A PC configuration tool and standard command set are available for integration.
