Dimmer expansion and Coralux 5up LDD board setup

[juszczyk]

hi, do I use one or all three grounds on the dimmer expansion and does it go to one of the grounds on the Corolux 5up board or to one of the -v on PS?

can you also explain why there are three grounds on the dimmer, thanks

trying to get all my wires going to corrects locations and there are a lot of wires.

Just to make it easier. You should be able to use any ground. I would use the dimming module one.

thanks Inevo, and does this ground go to the LDD boards ground or to the -v on PS, cheers

No sure how the board you mentioned is layout, but the ground from the power supply definitely needs to share the same ground of the dimming module.

[juszczyk]

ok, moved the ground from dimmer to -v on ps. still no success. If someone can look at my wiring to make sure everything looks ok would be great. I think my jumpers are correct for 5v pwm. Maybe I should try taking that lone jumper off to change from 40 to 41?

If everything looks ok, then I guess next step is looking at programing. Worst thing in world is thinking everything is good to go and once power is turned on, nothing happens.

It's the opposite.
You cannot use the jumper.
Jumper On = 0x41 - It will be used by the 16ch custom dimming expansion module
Jumper Off = 0x40 - To be used on the current 6ch dimming expansion module

juszczyk,

Did you get your set-up to work? I'm thinking of doing something similar.
