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: 1643 + 1644 +1. Test if Modbus-MTU works with PC commands. 1645 +1. Check if RS485-LN sent the expected command to Mobus-MTU 1646 +1. Check if Modbus-MTU return back the expected result to RS485-LN. 1647 +1. If both b) and c) has issue, we can compare PC’s output and RS485-LN output. 1648 + 1649 +[[image:image-20221130104310-1.png||height="380" width="680"]] 1650 + 1651 + 1652 +Example Connection: 1653 + 1654 +[[image:image-20221130104310-2.png]] 1655 + 1656 + 1657 +=== 6.7.2 Set up PC to monitor RS485 network With Serial tool === 1658 + 1659 + 1660 +(% style="color:red" %)**Note: Receive and send set to hex mode** 1661 + 1662 +[[image:image-20221130104310-3.png||height="616" width="714"]] 1663 + 1664 + 1665 +=== 6.7.3 With ModRSsim2: === 1666 + 1667 + 1668 +(% style="color:blue" %)**(1) Select serial port MODBUS RS-232** 1669 + 1670 +[[image:image-20221130104310-4.png||height="390" width="865"]] 1671 + 1672 + 1673 +(% style="color:blue" %)**(2) Click the serial port icon** 1674 + 1675 +[[image:image-20221130104310-5.png||height="392" width="870"]] 1676 + 1677 + 1678 +(% style="color:blue" %)**(3) After selecting the correct serial port and baud rate, click ok** 1679 + 1680 +[[image:image-20221130104310-6.png]] 1681 + 1682 + 1683 +(% style="color:blue" %)**(4) Click the comms.** 1684 + 1685 +[[image:image-20221130104310-7.png||height="376" width="835"]] 1686 + 1687 +(% class="wikigeneratedid" id="HRunRS485-LN2FBLcommandandmonitorifitiscorrect." %) 1688 +**Run RS485-LN/BL command and monitor if it is correct.** 1689 + 1690 + 1691 +=== 6.7.4 Example – Test the CFGDEV command === 1692 + 1693 + 1694 +RS485-LN sent below command: 1695 + 1696 +(% style="color:blue" %)**AT+CFGDEV=01 03 00 20 00 01,1**(%%) to RS485 network, and PC is able to get this command and return commands from MTU to show in the serial tool. 1697 + 1698 + 1699 +We can see the output from the Serial port tool to analyze.
