	1681	+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:
	1682	+
	1683	+1. Test if Modbus-MTU works with PC commands.
	1684	+1. Check if RS485-LN sent the expected command to Mobus-MTU
	1685	+1. Check if Modbus-MTU return back the expected result to RS485-LN.
	1686	+1. If both b) and c) has issue, we can compare PC’s output and RS485-LN output.
