• The return value is 2 bytes wide unsigned value, the unit is 1 m, the resolution is ΒΌ m, the range is from ‑1,024.00 m (value 0x0000) to +15,359.50 m (value 0xFFFE). Value 0xFFFF (i.e. 15,359.75 m) specifies a sensor error. Conversions are: Value = ( Altitude + 1024 ) * 4; Altitude = Value / 4 - 1024.
• FRC 2-byte: FRC return value is power value +4 (i.e. 0x1004=4,100 is 0.00 m). Because of FRC predefined values the altitude values from 0xFFFC to 0xFFFF (i.e. 15,359.00 m to 15,359.75 m) cannot be passed.
