Summary

The Serial Redirect feature can be utilized in two different ways. The most secure and recommended method is connecting to the routers WAN IP address through SSH and then typing “serial” at the CLI. Sent in plane text and not recommended you have the option to enable Telnet-to-Serial.

Cradlepoint highly recommends using the SSH-to-Serial access. We recommended SSH because communication is encrypted and requires username and password credentials before a connection is established. We recommend NOT using telnet-to-serial access unless the device is on a private network and NOT accessible from the Internet.

Requirements:

  • A USB-to-serial adapter that uses an FTDI chipset is required to use this feature. For more information on finding the right kind of adapter, consult the guide in the following link:
  • Make all the appropriate physical connections before beginning the configuration. Connect the USB-to-serial adapter to the USB port of the Cradlepoint router. Connect a console cable (RJ45-to-DB9) to USB-to-serial adapter cable. Connect to console port of the device you’d like to manage.

  • SSH/Telnet client - PuTTY is a simple, free SSH/Telnet client.

Troubleshooting

  • Re-seat connectors.
  • Try disabling/re-enabling the feature or rebooting the router.
  • Ensure you are able to access your device’s console through the USB-to-Serial adapter.
  • Check the RS232 settings on your device and make sure they match.
  • Verify the configuration of the end device. Most redirect errors are caused by the target device.
