Secondary address (decoder lock)
When using multiple decoders within the same housing, it is useful to use a secondary address that will
allow selecting a certain decoder from the group. In this way any of the decoders that are inside the same
housing (carriage or locomotive) can be programmed on the Programming Track without removing it. The
secondary addresses are programmed into CV16 before the decoders are being assembled in the housing.
The ranges of secondary addresses are 1-7 (value of
“
0
”
means that secondary addressing is not used).
This permits the use of maximum 7 decoders in the same carriage or locomotive housing.
If secondary address is enabled (CV16
≠
“0”)
, the decoders will accept programming commands only
after the value of CV16 is written also in CV15.
WARNING: even CV16 can be programmed only if the correct value is programmed in CV15.
The only CV that accepts read/write operation when secondary address is enabled is CV15 and it will
accept any value between 1 and 7, meaning that any value can be written even if it does not match the value
in CV16. So if the decoder secondary address if forgotten, it will take a maximum of 7 tries to find it out.
