NMRA CV 22 - Consist Lighting Control for Function 0 and Function 9 through Function 12

This CV is used to configure what functions will respond to user input on the Consist Address. This particular CV affects F0 and F9-F12. For each Bit which is set, that function will respond to instructions addressed to the consist address. Each bit which is cleared indicates that the function will only respond to instructions addressed to the locomotive's base address. F0F is controlled by Bit 0, F0R by Bit 1, F9 by Bit 2, and F12 by Bit 5.

To determine which functions are active, use the table below and combine the values of the functions you would like to have active, and program the sum into CV22.

Bit	Feature	Value	Default
0	Function 0 Forward	1	Control on Base Address
1	Function 0 Reverse	2	Control on Base Address
2	Function 9	4	Control on Base Address
3	Function 10	8	Control on Base Address
4	Function 11	16	Control on Base Address
5	Function 12	32	Control on Base Address

Version 5 Addendum

The behaviour of Function 0 Forward and Function 0 Reverse is different from all previous generations of TCS decoders. If you disable bits 0 or 1 in this CV, it will completely disable the output of that lighting function while in a CV19 consist. NOTE: The outputs for F0F and F0R will be disabled even if you have remapped these lighting outputs to different buttons other than F0.

This functionality also works with Rule 17 and Rule17 Opposite-Dim enabled, meaning that the same decoder can operate opposite-dim Rule 17 headlights when not consisted, and then automatically disable the (inner) headlight(s) when consisted.

Each direction can be disabled independently, or both can be disabled together. The configuration will take effect immediately whenever a consist address is placed in CV19.

If the bits are cleared for F0F and/or F0F, that light cannot be controlled from either the consist address or the base address - the output is disabled until the unit is removed from the CV19 consist.
