NMRA CV 13 - DC Mode Function Status F1-F8

Indicates the status of each function (F1 through F8) when the unit is operating in alternate power (DC) mode, which cannot control the functions. If a function can be controlled, then the corresponding bit is ignored.

If the bit for a function output is "cleared," this indicates the function is disabled on DC power. If the bit for a function output is "set," this indicates the function is enabled on DC power. CV 12 is a bitwise CV, where Bit 0 corresponds to F1, while Bit 7 corresponds to F8. See the chart below:

Feature Value
Function 1 1
Function 2 2
Function 3 4
Function 4 8
Function 5 16
Function 6 32
Function 7 64
Function 8 128

The SUM of the desired functions active while operating in DC mode must be programmed into CV 13. A value of 255 enables all light functions on DC power.
