3. Identify the Serial Port:
   • After driver installation, open your PC's "Device Manager" (Windows) or equivalent system utility (Mac/Linux).
   • Locate the newly installed Virtual COM Port (VCP) under "Ports (COM & LPT)". Note the assigned COM port number (e.g., COM3, COM4).

4. Operating Instructions

Once the cable is physically connected and drivers are installed, configure your BMS software for communication:

1. Configure BMS Software:
   • Open the JK JIKONG BMS monitoring or configuration software on your PC.
   • Navigate to the communication settings within the software.
   • Select the COM port number identified in the previous setup step (e.g., COM3).
   • Ensure that other communication parameters, such as baud rate, match the requirements of your specific JK JIKONG BMS model.

2. Establish Connection:

   Initiate the connection within the BMS software. The software should now be able to communicate with your JK JIKONG BMS, allowing you to monitor parameters, configure settings, and perform diagnostics.

5. Maintenance

The usangreen USB to RJ11/RJ12 RS232 Serial Converter Cable is designed for durability with a PVC jacket and bare copper wires. To ensure longevity and reliable performance:

• Store the cable in a clean, dry environment when not in use.
• Avoid sharp bends or kinks in the cable, especially near the connectors, to prevent internal wire damage.
• Do not expose the cable to extreme temperatures or direct sunlight for extended periods.
• Clean the connectors gently with a dry, lint-free cloth if necessary.

6. Troubleshooting

If you encounter issues while using the usangreen USB to RJ11/RJ12 RS232 Serial Converter Cable, consider the following troubleshooting steps:

• No Connection/Device Not Recognized:
  • Verify Driver Installation: Ensure the FTDI VCP drivers are correctly installed. Re-download and install them from the official FTDI website if necessary.
  • Check Device Manager: Confirm that the Virtual COM Port appears in your PC's Device Manager without any error symbols.
  • Try Different USB Port: Connect the cable to a different USB port on your PC.
  • Restart PC: A system restart can sometimes resolve driver recognition issues.
• BMS Software Communication Failure:
  • Correct COM Port: Double-check that the correct COM port is selected in your BMS software, matching the one identified in Device Manager.
  • Baud Rate Mismatch: Ensure the baud rate in the BMS software matches the required baud rate for your JK JIKONG BMS model.
  • BMS Compatibility: Confirm that your specific JK JIKONG BMS model (XR04, XR05) has an RS232 communication port. This cable is designed for RS232 communication, not CAN.
  • Cable Integrity: Inspect the cable for any visible damage or loose connections.
