LONWORKS Neuron Chip

[lak]

Hi Sonsivrians,

Anyone here familiar with the Echelon Lonworks Neuron 3150 chip module (obsolete part)?

The problem is that the service led is lit up and apparently is 'blinking' at 76hz.
The application resides in a external eprom.
I have placed the board into the train cabin system and pressed the service button thinking
that it was a configuration/network/ID  problem.
But the amber led light persisted. All is well if I change to a new board.

Appreciate if anyone here can tell me what I can do to make this board operational?

thanks
