17.4.3 Reset to Defaults – Jumper J1
In the event that you change the network settings in such a way
that you can no longer access 190-WIFI, a jumper has been
provided (J1 DEFAULT) to reset the network configuration to the
initial factory defaults.
To reset the 190-WIFI module to defaults, set the jumper in the
shorted position and apply power to the 190 indicator. You should
see the DEFAULT LED (D3) light up while 190-WIFI is in the
process of resetting the configuration. When the reset to defaults is
complete you should see the LED flash 5 times and then go out
when it is complete.
It is necessary to completely remove power and re-apply power to
ensure that the default settings have taken effect.
This means that it is very important that the DEFAULTS jumper
NOT be left in place on the board for normal operation and should
only be used if trying to recover a module with incorrect settings.
At this point, 190-WIFI should continue with normal operation using
the default configuration.
NOTE: The DEFAULTS jumper will launch the configuration web
page if set briefly after power up.
