1837 -== 6.8 Where to get the decoder for RS485-LN? ==
1838 -
1839 -
1840 -The decoder for RS485-LN needs to be written by yourself. Because the sensor to which the user is connected is custom, the read device data bytes also need custom parsing, so there is no universal decoder. We can only provide [[templates>>https://github.com/dragino/dragino-end-node-decoder/tree/main/RS485-LN]] for decoders (no intermediate data parsing part involved)

1843 -== 6.9 How to configure RS485 commands more conveniently？ ==
1844 -
1845 -
1846 -Dragino has developed an application for the RS485 series of products.
1847 -
1848 -It can help you configure RS485 sensors more conveniently
1849 -Please refer to the link below for specific usage：

1855 -== 6.10 How to determine whether the returned data value FF is valid data or invalid data? ==
1856 -
1857 -The address of the returned data can be used as a flag.
1858 -
1859 -The customer uses the intercept command to intercept the first bit of the returned data (the slave address of the sensor) as a judgment flag.
1860 -
1861 -**Invalid data:**
1862 -
1863 -If the first bit and the data are both FF, it means the data is empty.
1864 -
1865 -
1866 -**Valid data:**
1867 -If the first bit is a normal slave address and the data is FF, it means the data is normal.
