Re: Multiple LEDs on FX-DO

Thanks. Is your FX-DO for sale?
Now down to the point. I understand all what you said and will look for a solution to operate more than one LEDs on one port, under the condition that I can actually get the decoder ports working!
My problem is that the ports are all messed up by default, as it seems, and I can't get them to work the way I want.
There is, of course, no manual for the FX-DO and it's impossible to figure out what function is assigned to what port.
Now this probably wouldn't normally be a problem but my Quantum Programmer also developed a fault recently and I can't get it to work. Thus I tried manual programming of CVs.
I reset the decoder, I set all the values of all the CVs shown in the Feature to Port Mapping table of Quantum CV Manager to zero, so in theory no lights should be operating. And still I have some lights that are on. Then I try to assign features to a certain port but they are not in the sequence as the pins on the decoder. This is what I could identify so far:
pin2 = port 4
pin3 = port 3
pin5 = port 1
pin6 = port 8
pin9 = port 5,
where the first two pins on each 6-pin connector are GND and 5V+, thus I call pins 3-8 of the first connector as pins 1-6 and pins 3-8 of the second connector as pins 7-12.
So I am trying to figure out for example what port is assigned to pin 4. I have no feature assigned to anywhere and try to set, say, step lights to pin 4. I try all the values from 1 to 12 on CV 115.113.0 and the single light attached to that pin will not be on for any of those values.
This just drives me crazy, I thought I could at least manually figure out what pin corresponds to what port but no such luck...
KJ, do you think you could perhaps see what function output pin on your FX-DO corresponds to what port?
