grandma3 dmx in with conventional light desk

  • Hi !

    I'm currently discovering my new grandma3 compact and try to connect in DMX in a conventional light console ( AVAB Presto ) with the idea to have more physical faders.


    I connected the conventional console on port G and setted the universe on 1 : I want to be able to command conventional dimmer with conventiional console or/and with grandma3.

    It works a bit, I can control my dimmers with both consoles.

    The problem is that grandmaster has no effect on dmx in values. What do I do wrong ? I tried different parameters on Merge G but did not get the expected results.

    Another thing is completely crazy : If I light up dimmers with conventional console, they light up trough grandma, but if I lower grandmaster on conventional console, dimmers stay light up on grandma !

    DMX in that worked rather fine on grandma2 seems to be very bugged on 3.


    did someone met the same issue ?

  • I have a Command Wing XT here, with a simple 16-channel fader board hooked up through DMX-in. So, comparable setup to yours.

    You're not actually putting the incoming DMX values into the gMA3 GUI. you're just pushing the incoming DMX onto the outgoing line. The GrandMaster, as such, would not have any effect, because it only controls output that's generated by MA3. If I'm not mistaken, MA2 does the same thing, unless you set an incoming channel to "Programmer". Which would put the incoming DMX values into the Programmer. i don't think a similar function has been implemented in MA3, so far.

  • Did you connect the input with DMX Remotes? There you it should be possible to connect external DMX with 'virtual' Executor Faders or buttons.

    And it is important to turn off the Universes as well. So if you use Univere 1 for Input and Output, then you will have a 'direct output' on channel 1 e.g. if you raise Ch. 1 from the external Desk... So just use your input universes for input only and not for output!


    If you understand german: there is a wonderful webinar video about external Inputs on the eleraning university of Lightpower where this is all explained.

    I'm a switcher from Chamsys-System to MA3. Having a MA3-Wing, Vizkey, and 2K onPC-Node.

  • Hi guys,


    And thank you for your answers !


    Indeed, the best thing i guess i have to do is to use dmx remotes : The idea is to use conventional desk to have more faders ( instead of buying an extra MA desk ! :D )

    now i can control a group with conventional desk, it's not too bad, but what i would like is to "capture" dimmer group levels in progammer. for the moment, i can just capture fixtures with " if please", but not the levels.


    I understand a little german, I'm going to have a look at eleraning university of Lightpower.

  • Hi again !


    finally i could resolve my "capture" dmx issue with assigning dmx in remote to a sequence, and doing " if output" and typing 3 times " please" after, it captures sequence levels in programmer. it does what i want to do !


    I would like to do a macro for this, has someone an idea of the right syntax ?


    regards,
