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: 1652 - 1653 -1. Test if Modbus-MTU works with PC commands. 1654 -1. Check if RS485-LN sent the expected command to Mobus-MTU 1655 -1. Check if Modbus-MTU return back the expected result to RS485-LN. 1656 -1. If both b) and c) has issue, we can compare PC’s output and RS485-LN output. 1657 - 1658 -[[image:image-20221130104310-1.png||height="380" width="680"]] 1659 - 1660 - 1661 -Example Connection: 1662 - 1663 -[[image:image-20221130104310-2.png]] 1664 - 1665 - 1666 -=== 6.7.2 Set up PC to monitor RS485 network With Serial tool === 1667 - 1668 - 1669 -(% style="color:red" %)**Note: Receive and send set to hex mode** 1670 - 1671 -[[image:image-20221130104310-3.png||height="616" width="714"]] 1672 - 1673 - 1674 -=== 6.7.3 With ModRSsim2: === 1675 - 1676 - 1677 -(% style="color:blue" %)**(1) Select serial port MODBUS RS-232** 1678 - 1679 -[[image:image-20221130104310-4.png||height="390" width="865"]] 1680 - 1681 - 1682 -(% style="color:blue" %)**(2) Click the serial port icon** 1683 - 1684 -[[image:image-20221130104310-5.png||height="392" width="870"]] 1685 - 1686 - 1687 -(% style="color:blue" %)**(3) After selecting the correct serial port and baud rate, click ok** 1688 - 1689 -[[image:image-20221130104310-6.png]] 1690 - 1691 - 1692 -(% style="color:blue" %)**(4) Click the comms.** 1693 - 1694 -[[image:image-20221130104310-7.png||height="376" width="835"]] 1695 - 1696 -(% class="wikigeneratedid" id="HRunRS485-LN2FBLcommandandmonitorifitiscorrect." %) 1697 -**Run RS485-LN/BL command and monitor if it is correct.** 1698 - 1699 - 1700 -=== 6.7.4 Example – Test the CFGDEV command === 1701 - 1702 - 1703 -RS485-LN sent below command: 1704 - 1705 -(% style="color:blue" %)**AT+CFGDEV=01 03 20 00 01 85 c0,1**(%%) to RS485 network, and PC is able to get this command and return commands from MTU to show in the serial tool. 1706 - 1707 - 1708 -We can see the output from the Serial port tool to analyze.
