    J-Link Built-in web server

    The J-Link Built-in web server, based on emWeb, is a web server running in the J-Link or J-Trace itself.

    The J-Link control panel provides an easy way to monitor and configure J-Link as well as J-Trace probes.

    Information about power usage, connection status, operating speed, firmware version, heap fragmentation and much more can be found inside the web control panel.

    For all models supporting Ethernet, the built-in web server is directly available on port 80 of the IP address of the J-Link or J-Trace.
    It is also available for regular J-Link BASE and PLUS and ULTRA+ models via IP-over-USB.

    The J-Link Built-in web server can be activated by launching any J-Link application, for example the J-Link commander. After that, the built-in server is up and running and can be accessed.
