Вот ответ который мы получили из Echelon
This is Paul Robinson fom LonSupport here. I am sorry to hear that you are
having problems with a U10 device. The fact that the service pin is on all
the time and the error is as shown indicates that the U10 is
applicationless. The usual cause of this is the use of Nodeutil to ®eboot
the network interface. Unfortunately this resets the comms parameters of
the
neuron in the USB adapter to TP1250. The application sees this as a
configuration checksum error and renders the device applicationless, hence
the yellow LED on all the time. If you test the device in the USB tab of
the LonWorks Interfaces applet you will get an error which says "Failed to get
Layer L2/L5 Configuration".
Предлагают купить новое устройство:( Хотя проблема в том что слетела прошивка!
Если разобрать адаптер можно ли , залить прошивку в чип с помощью программатора без LON сети и где ее взять?
