On my BLI locos I found that I had to set the horn and coupler - functions to non-latching. This prevents them from sounding off every time power is interrupted.
Many DCC systems do not allow for configuring functions (other than F2) to be non-latching. What system do you have?
I'm running a Digitrax Super Chief system.
Horn (F2) is I believe non-latchgin by default on all American DCC systems, but what function key is the coupler assigned to?
My thinking is that the latching of functions is dependent on the decoder not the system.
No. The function states are sent from the command station, think the rails, to the decoder. Decoder just sees what state the function is (on or off) in the packets it receives from command station. The latching or non-latching feature could only be defined in the command station.I wonder if you just think they are non latching? But some functions on some decoders seem to be triggered by a state change of the function, while others will only work if the function is active.Does your throttle's display show the state of the functions? If it does, then you could positively see whether a function is latching or non-latching. Or do you actually recall how you configured functions on the command station/throttle to be either latching or non-latching?I don't recall seeing this type of a feature in the Digitrax manuals, but I have not read them for several years. I know that the NCE system does not feature configuring function keys to be latching or non-latching.
Well my memory is not what it once was -- I am setting the latch/non-latch in JMRI, and it only works for JMRI throttles. OOPS my bad.
