1643 -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:

1645 -1. Test if Modbus-MTU works with PC commands.
1646 -1. Check if RS485-LN sent the expected command to Mobus-MTU
1647 -1. Check if Modbus-MTU return back the expected result to RS485-LN.
1648 -1. If both b) and c) has issue, we can compare PC’s output and RS485-LN output.

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)
