Router Option Card for Lon® Star Coupler
RER 111
Appendix A
Default values of communication parameters and routing tables for the router option
card, sides A and B.
These default values are set during manufacturing and they are stored in EEPROM
memory of the Neuron chip. Configuration structure values may be read and written
over the LONWORKS network using Read Memory and Write Memory network
management messages addressed to the router option card (for more details see
LONWORKS Technology Device Data chapter A6: The configuration structure).
