DMX Output Frequency

Was Teching my FB4's internal DP and four dmx ports before taking it out on a job and noticed that even though the H4 software allows for you to increase DMX Refresh Rate to an upward number of 44hz, that the maximum actual DMX RR is limited to 29hz.

Is this by design?

Are we limited to 29hz on all internal DP's?

Are all of the External DP's limited to the same RR?

Can we get 44hz out of artnet and a 3rd party node?

Don't have a node or an external DP to test as I'm at home right now..

Would appreciate a reply from HES.

    Sorry, my post was not fully clear
    You are right what you are saying, the thing is that some fixtures have a problem when not all 512 channels are transmitted, even if you send the correct start-byte.
    I was refering to what JB said that lowering the transmitted channel-number would speed it up. I had fixtures that really had problems when you lower the number of transmitted channels (I did this with AVO Pearl and Diamond several years ago). Cant remember exactly if it was the amount of time between to start bytes or what caused it, but the DMX Receiver in these fixtures and dimmers was a bit picky when it was too fast. Like you need sometimes to slow the DMX down with some china-LEDs...

    The option to speed it up to 44Hz should be there, I fully agree that.
