DMX Hell!

[leononeill]

Help! I'm using LED par's with a Stairville DMX Master 1 controller. All is well, I can program scenes, chases, all the adressing, etc is correct.

Then I introduce the Showtec Lightfoot 4 foot controller to perform basic scene changes, etc, and the whole rig goes haywire! It's as if the mixer is jammed, fast, random bursts of colour down the first fixture in the chain, nothing I do on the foot controller makes any difference. is it that these two pieces of equipment are not compatible? I am using DMX, not MIDI between the DMX Master 1 and the Lightfoot, because the distance from stage to front-of-house as too long, in my opinion, to run a reliable MIDI signal. Please help!!!

It sounds to me like you have put two DMX transmitters onto the same DMX line. Not quite sure how you could have managed that but it certainly won't work. You can only have one DMX transmitter on a data line unless you use a DMX merge device.

Don't know much about Showtec controllers but is your DMX line terminated?

I'm fairly sure Dave has hit the nail squarely on the head.

As stated above both your products are transmitters and 2 transmitters on the same line will not work with out a merger. I`m wondering on how you even got them both on the same line and what your intention was with the Light Foot 4 ? If you where planing to use it as a remotecontroller to change scenes on your DMX Master I have to disapoint you and tell you that this will not work.

 

However someting could work while still having them on the same line could be to kill the GM on the DMX Master at the same time as you kick in someting from your Light Foot and then pull it up again when you are done using the scene/chase or whatever from the Light Foot?

No, that won't work either! Even if the intensities on the Stairville controller are at zero it will still be transmitting DMX data.

Meh, forgott it I does... posting late at night was never a good idea :(

The "Stairville DMX Master 1" has a DMX Input. But in the manual there is no hint how to use the input. Perhaps its a merger or a remote controll.

It is a simple pass through. My brother bought one to see if it could be used as a merger and it doesn't work.

The DMX IN is so you can clone one controller's memory onto another, there's a mode in the setup menu you can put the slave controller into, for a memory dump. That's the only thing it's for, early versions have the socket but dont have the firmware yet.
