NMRA CV 17 - Extended Address (High 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#17 contains the most significant bits of the two byte address and must have a value between (192) 11000000 and (231) 11100111, inclusive, in order for this two byte address to be valid.

The default configurations 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 17 by 1 will increment the Long Address by 256.

Example 1:

(CV 17 = 193; CV 18 = 0) Long Address = 0256

Example 2:

(CV 17 = 231; CV 18 = 0) Long Address = 9984
