NMRA CV 16 - Decoder Lock (Lock)
The Decoder Lock feature is used to change CVs in only one of several decoders with the same short address (CV1) or long address (CV17 and CV18). Typically this becomes a concern only when multiple decoders are installed in the same locomotive.
To use Decoder Lock: Program a number between 1 and 6 into CV16 in each decoder (see the chart below for the standard values) before the decoders are installed in the locomotive. To change a value in another CV of one of the installed decoders, first write the corresponding number into CV15, then send the new value to the CV to be changed. The decoders will compare CV15 to CV16 and, if the values are equal, the CV to be changed will be changed.
By default, a DCC decoder will be unlocked, but may or may not have a value set in CV16.
If the values in CV15 and CV16 are different, the decoder is considered locked, and programming request will be ignored.
| Decoder Type | Lock # |
