.inffile and select "Install," or use the Device Manager to update the driver by pointing it to the extracted folder. - Mac: Run the included installer package.
- Windows: Right-click the
- Connect: Plug the USB cable into the Cisco device.
- Configure: Open a terminal emulator (PuTTY is the industry standard) and connect to the newly generated COM port (e.g., COM3, COM4).
macOS — Install (macOS 10.13+ / Sonoma-era)
- Double-click the .pkg in the extracted folder.
- Follow prompts and authenticate with an admin username/password.
- On first load, macOS may block kernel extension or system extension. If you see a security block:
- Open System Settings → Privacy & Security → allow the Cisco system extension (may require unlocking).
- You may need to reboot for the extension to load.
- Connect the Cisco USB console cable to Mac and device.
- Open Terminal and list serial devices:
- macOS device name usually appears as /dev/tty.usbserial-XXXX or /dev/cu.usbserial-XXXX
- To list:
ls /dev/tty.* /dev/cu.*and identify new entry after plugging cable.
- Use terminal program (screen, ZTerm, Serial Studio, CoolTerm):
- Example with screen:
screen /dev/tty.usbserial-XXXX 9600 - To exit screen: Ctrl-A then K, confirm with Y.
- Example with screen:
Uninstall on macOS:
- If an uninstall script is provided, run it with sudo. Otherwise remove kernel/system extension per README and reboot.
Example terminal settings (common)
- Baud: 9600 (try 115200 if no response)
- Data bits: 8
- Parity: None
- Stop bits: 1
- Flow control: None
