Wink LED Error
Codes
The Wink LED is used to display error conditions. The following table shows the
number of times the LED blinks for each type of error.
Front Panel Push
Buttons
Two push buttons are located on the front of the NOL module. The service pin push
button initiates the LonWorks network installation. When depressed, it causes the
Service LED to illuminate, and forces the Neuron Chip in the module to output its
unique 48-bit ID and Program ID.
The reset push button performs a hardware reset of the module, and must be done
each time new firmware has been downloaded.
