NMRA CV 18 - Extended Address (Low Byte)
The Extended Address is the locomotives address when the decoder is set up for extended addressing (indicated by a value of "1" in bit location 5 of CV#29). CV 18 contains the least significant bits of the address and may contain any value from 0 to 255.
The default configuration of CV 17 and CV 18 yield an address of "0000" and may be selected as such when Long Addressing has been enabled but CV 17 and CV 18 have not been otherwise configured.
Incrementing CV 18 by 1 will increment the Long Address by 1.
Example 1:
(CV 17 = 192; CV 18 = 1) Long Address = 0001
Example 2:
(CV 17 = 192; CV 18 = 255) Long Address = 0255
