I have spotted something that may be of interest. It appears all function buttons toggle on and off. So when you press a function button you turn the function on. Press the same button again and you turn the function off. Now this fully explains why I have being getting what I thought was erratic behaviour when using F2 and F3 on the EZ-Command control pad to control the horn of the Bachmann sound loco. Sometimes it appeared to work and sometimes it didn't.

It seems that the first time you use the horn you only press the button once to turn the horn function on. For all second and subsequent horn use you have to push the function button twice to turn the horn function off and back on again.

Bachmann should make this a bit clearer in their instructions. Certainly when everybody was having a go with the sound loco at Warley MRC there was much comment on why the horn did not work when the function button was pressed and then it did which made it all seem very erratic and I did not have the answer. Now I do!

There was suddenly a moment of inspiration when using the Elite on/off button. Everything DCC has a logical answer it seems. Its the humans who cause the problems!

OK it might be a discovery made by a newbee however how many others have been kicking their console around the room as a result of function buttons that appear to have a mind of their own!

Happy modelling

When I am writing software for consumer products, I seem to spend most of my time writing code to handle situations where something has gone wrong.

This apparently is the standard feature for the function buttons,the ZTC511 which I have is exactly the same.
As I understand it these function buttons were originally specified like this so as to turn a specified function (ie. lights etc) on and then off.
Hence the toggle action.
I am on the understanding that the new Dynamis buttons will be user programmable to eliminate this problem.

Using Lenz, you can define if a function is 'on' with one press (then straight 'off'), or 'on' with one press then followed by 'off' with another press.

Some functions like the horn (sound decoder) require the button to be set with 'on' with one press (then straight 'off'), other functions like reduced shunting speed require 'on' with one press then followed by 'off' with another press.

according to bachmann dynamis web site faq's you are able to set to latch or trigger, which latch means on/off when ever the fuction button is pushed. trigger is sounding the horn/whistle by pressing the button again. is the way i read it, in other words once the decorder is set to trigger and on, pressing the function button at anytime will sound the horn or whatever without turning the function off. hope this helps.

I have a few which operate like this and some where every touch of the appropriate function button triggers the sound. All the decoders are Loksound so they must be set this way for some reason.

I've had the same thing - I think you can change the decoder and/or console settings on most setups.
