Operating
Some functions such as a firmware update or changing of the IP-address and
HTTP settings require a restart of the device. A jump to the boot loader or a restart of
the device lead by no means to a change of the relay states.
Enter Bootloader Mode: Jumps into bootloader mode, where additional settings can be
made with GBL_Conf.exe.
Flush DNS Cache: All entries in the DNS cache are discarded and address resolutions
are requested again.
Restore Fab Settings and Restart Device: Performs a restart and resets the device to
factory default.
