1642		-
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:
1644		-
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.
