Mendouconert USB to 6-pin Mini Din RS232 Serial Communication Cable User Manual

1. Product Overview

The Mendouconert USB to 6-pin Mini Din RS232 Serial Communication Cable is designed for reliable data transfer between a personal computer (PC) and various LS XGB, XBM, and XBC series Programmable Logic Controllers (PLCs). This cable facilitates control and program download operations, ensuring seamless communication for industrial automation tasks.

Equipped with an authentic FTDI FT232RNL chipset, the cable provides stable and efficient serial communication. It functions by creating a Virtual COM Port (VCP) on your PC, allowing existing application software to interact with the connected PLC as if it were a standard serial port.

4.1 Driver Installation

Before connecting the cable, it is crucial to install the appropriate Virtual COM Port (VCP) drivers for your operating system. These drivers enable your computer to recognize the cable as a standard serial port.

1. Download Drivers: Visit the official FTDI website to download the latest VCP drivers compatible with your operating system. The direct link for installation guides is typically found at ftdichip.com/document/installation-guides/.
2. Install Drivers: Follow the specific installation instructions provided on the FTDI website for your operating system. This usually involves running an executable file or following a manual installation process.
3. Verify Installation: After installation, you can verify the successful driver installation by checking your computer's Device Manager (Windows) or equivalent system information utility (Mac/Linux). Look for a new COM port listed under "Ports (COM & LPT)" or similar categories.

4.2 Hardware Connection

1. Connect to PC: Insert the USB Type A connector of the cable into an available USB port on your computer.
2. Connect to PLC: Insert the 6-pin Mini Din connector into the corresponding serial communication port on your LS XGB, XBM, or XBC series PLC. Ensure the connection is secure.

5. Operating Instructions

Once the drivers are installed and the cable is physically connected, your computer will recognize the cable as a Virtual COM Port. This allows your PLC programming or communication software to interact with the connected PLC.

1. Launch Software: Open your PLC programming software (e.g., LS Electric KGL-WIN, XG5000, etc.) or any other application designed for serial communication with your specific PLC model.
2. Select COM Port: Within your software's communication settings, select the Virtual COM Port number that was assigned to the USB cable (e.g., COM3, COM4, etc.). This number can be found in your Device Manager.
3. Configure Communication Parameters: Ensure that the communication parameters (baud rate, data bits, parity, stop bits, flow control) in your software match the settings required by your PLC. Refer to your PLC's documentation for the correct parameters.
4. Establish Connection: Initiate the connection from your software. You should now be able to upload/download programs, monitor PLC status, or perform other communication tasks as supported by your software and PLC.

6. Troubleshooting

• Cable Not Recognized:
  • Ensure FTDI drivers are correctly installed. Re-download and reinstall if necessary from ftdichip.com.
  • Try a different USB port on your computer.
  • Restart your computer after driver installation.
• Communication Errors:
  • Verify that the correct COM port is selected in your PLC software.
  • Check that all communication parameters (baud rate, data bits, parity, stop bits, flow control) in your software match the PLC's requirements.
  • Ensure the 6-pin Mini Din connector is securely seated in the PLC port.
  • Confirm that the PLC is powered on and in a communication-ready state.
  • Test the cable with another compatible device or computer if possible to rule out cable malfunction.
• Intermittent Connection:
  • Check for physical damage to the cable or connectors.
  • Avoid excessive bending or pulling on the cable.
  • Ensure no other software is using the same COM port simultaneously.

7. Maintenance

To ensure the longevity and optimal performance of your serial communication cable, follow these maintenance guidelines:

• Storage: Store the cable in a cool, dry place away from direct sunlight and extreme temperatures. Avoid tightly coiling or kinking the cable, which can damage internal wires.
• Cleaning: Use a soft, dry cloth to clean the cable and connectors. Do not use liquid cleaners or solvents, as they may damage the insulation or electronic components.
• Handling: Always grasp the connector housing when plugging or unplugging the cable. Avoid pulling on the cable itself, as this can strain the connections and lead to internal damage.
• Inspection: Periodically inspect the cable for any signs of wear, cuts, or damage to the insulation or connectors. If damage is observed, discontinue use and replace the cable.
