Setup

Follow these steps to set up your USB C to RJ45 Console Cable:

1. Driver Installation: For most modern operating systems like Windows 10 and the latest macOS versions, FTDI drivers are often included and installed automatically upon connecting the cable. If drivers are not automatically installed, you may need to download them from the Cable Matters support website. Refer to the official user guide (PDF) for detailed driver installation instructions.
2. Connect USB-C End: Insert the USB-C connector of the cable into an available USB-C port on your computer (laptop, desktop, or even compatible Android phone).
3. Connect RJ45 End: Insert the RJ45 connector into the console port of your networking device (router, switch, server, or wireless access point). Ensure it is securely seated. The cable features a snagless RJ45 connector to prevent damage during connection and disconnection.

Operating Instructions

Once the cable is physically connected and drivers are installed, you can begin configuring your networking equipment. This cable is specifically designed for console access and should not be used as a standard Ethernet cable for network data transfer.

Using with Terminal Emulation Software:

You will need terminal emulation software (e.g., PuTTY, Tera Term, SecureCRT for Windows; Screen, minicom, or iTerm2 for macOS/Linux) to communicate with your networking device. The cable uses a standard Cisco USB to RJ45 pin-out, reversing all 8 pins for rollover functionality.

• Identify the Serial Port: After connecting the cable, your operating system will assign a virtual serial port (e.g., COM port on Windows, /dev/cu.usbserial-XXXX on macOS/Linux). You can find this in Device Manager (Windows) or by using commands like ls -l /dev/cu.* (macOS/Linux).
• Configure Terminal Software:
  • Select the identified serial port.
  • Set the baud rate (common rates include 9600, 19200, 38400, 57600, 115200). The correct baud rate depends on your networking device's console port settings.
  • Set data bits to 8, parity to None, stop bits to 1, and flow control to None (8N1).
• Establish Connection: Open the serial connection in your terminal software. You should now be able to send commands to and receive output from your networking device.

Maintenance

To ensure the longevity and optimal performance of your Cable Matters USB C to RJ45 Console Cable, follow these maintenance guidelines:

• Storage: Store the cable in a cool, dry place away from direct sunlight and extreme temperatures. Avoid tightly coiling the cable, especially around the connectors, to prevent internal wire damage.
• Cleaning: Use a soft, dry cloth to clean the cable and connectors. Do not use liquid cleaners or solvents, as they may damage the cable's insulation or internal components.
• Handling: Always grasp the connector housing when plugging or unplugging the cable. Avoid pulling on the cable itself, as this can strain the internal wires and lead to damage.
• Protection: The RJ45 connector features a snagless clip protector. Ensure this protector is intact to prevent the tab from breaking off, which could cause the connector to become stuck or lose connection.

Troubleshooting

If you encounter issues with your USB C to RJ45 Console Cable, consider the following troubleshooting steps:

• No Device Detected / Driver Issues:
  • Check Device Manager (Windows) / System Information (macOS): Verify that the cable is recognized by your computer. Look for "USB Serial Port" or similar entries.
  • Manual Driver Installation: If not detected, download and install the latest FTDI drivers directly from the Cable Matters support website or FTDI's official site.
  • Try Different USB-C Port: Test the cable in another USB-C port on your computer.
• No Output in Terminal Software:
  • Verify Port Selection: Ensure you have selected the correct serial port in your terminal emulation software.
  • Check Baud Rate: The most common cause of garbled or no output is an incorrect baud rate. Cycle through common baud rates (9600, 19200, 38400, 57600, 115200) until you find one that works.
  • Confirm 8N1 Settings: Ensure data bits are 8, parity is None, and stop bits are 1. Flow control should typically be None.
  • Cable Seating: Disconnect and reconnect both the USB-C and RJ45 ends to ensure a firm connection.
  • Device Console Port Status: Ensure the networking device's console port is enabled and functioning correctly.
• Intermittent Connection:
  • Cable Integrity: Inspect the cable for any visible damage, kinks, or frayed areas.
  • Port Stability: Ensure the USB-C port on your computer and the RJ45 port on your networking device are clean and free of debris.
