Local Device Management

Last updated: May 5th, 2026 - 2 min. read

All ReadyLinks devices come with the ability to locally manage and configure the device via its web user interface or serial access port. This article provides instructions on how to access the serial interface and web UI of a ReadyLinks device.

Serial Interface

Each ReadyLinks device comes with either a standard RS-232 or a USB Type-C console port cable. Most ReadyLinks devices feature a combo USB Type-C/RJ45 console port interface, either port can be used for serial access, but note that both interfaces should not be used at the same time.

Using your serial access application of choice (i.e PuTTy), connect your PC to the ReadyLinks device and use the settings below to access the serial command line interface (CLI) of your device.

Default credentials

  • superuser
  • 123

Serial settings

  • Bit rate: 115200
  • Data bits: 8
  • Parity: None
  • Stop bits: 1
  • Flow control: None

USB Type-C driver support

Some ReadyLinks devices require a virtual COM port driver to be installed on the host PC before the USB Type-C console port can be used. The driver is provided by the chip manufacturer (MaxLinear XR21V1412); download the package matching your operating system below.

Type Title Version Date File Size
Software: Drivers MacOS 15 and later Installation Package 1.1 November 2025 1.4 MB
Software: Drivers Linux 3.6.x and Newer 1G August 2024 29.7 KB
Software: Drivers Windows 10 and newer 2.7.0.0 January 2023 169.2 KB
Software: Drivers Windows 7, 8 2.6.0.0 December 2019 145.7 KB
Software: Drivers Linux 2.6.18 to 3.4.x 1A January 2015 19.1 KB

Note: The Windows drivers listed above are only compatible with Intel-based processors (x86 and x64). ARM-based Windows is not supported.

Note: Once the Windows driver is installed and the device is connected, it will appear in Device Manager under Ports (COM & LPT) as XR21V1410 USB UART (COMn), where COMn is the COM port number assigned by Windows. Use that COM port number in your serial application.

Web Interface

Every ReadyLinks device features a web based, Graphical User Interface (GUI), for device managment and monitoring. By default, access to this GUI is disabled.

Enable web GUI access
  • Login to the device via the serial interface
  • Run command 'configure terminal' to enter configuration mode
  • Run command 'management mode disable' to enable access to the web UI

By default, ReadyLinks devices are provisioned as a DHCP client. Once the device is connected to a DHCP server, find the device's IP address, then open that address in a web browser.
