Paul,
A big thanks for taking the time to document how to use this feature.
I have implemented it on one of my sound fitted Farish N gauge class 66,(Zimo MX648) so I can control the white and red lights independently. (as per your explanation)
The alternative as you know was to remap a couple of the sound features to ‘free’ up some of the lower number function buttons, this is a lot easier.
I do have one question, which I am not sure if it’s due to the way I have configured it, or the way Swiss mapping works.
I am using F21 to control the white lights and F22 to control the red lights. If I place the loco on the track and turn the lights on, it functions correctly.
If I now remove the loco, without turning of either F21 or F22 and then replace it, neither sets of lights will come on (both F21 and F22 are still switched on at this stage).
If I then toggle (off / on) either F21 or F22, then both sets of lights work correctly.
Have I missed a configuration, or is this correct.
Regards,
Gordon D
