1654 -Users can use below the structure to fast debug the communication between RS485BL and RS485-LN. The principle is to put the PC in the RS485 network and sniff the packet between Modbus MTU and RS485-BL/LN. We can use this way to:
1655 -
1656 -1. Test if Modbus-MTU works with PC commands.
1657 -1. Check if RS485-LN sent the expected command to Mobus-MTU
1658 -1. Check if Modbus-MTU return back the expected result to RS485-LN.
1659 -1. If both b) and c) has issue, we can compare PC’s output and RS485-LN output.

1758 -== 6.8 Where to get the decoder for RS485-LN? ==
1759 -
1760 -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)
