LON initialization:
In this special maintenance mode you can
control the Neuron processor's service pin
which is on the LON-200 card so that the
Neuron sends the bus its own identification (48
bit Neuron ID). This procedure is necessary
when initializing EH-203 + LON-200 into the
facility's LON net
