DMX Out

Post by mmeffects » Wed 09 Jul, 2003 5:03 pm

Hallo

Die LD 2000 Karte hat ja auch DMX out.

Nur ist die LD Software nicht grad DAS DMX Pult... Hat jemand eine Ahnung ob(und) wie sich der DMX Port ansteuern lässt?

Ich denke da so an Software ala Lightdesk Scanshow oä.

Ciao

MM

Hi,

nunja, eine QM2000 als DMX Pult zu missbrauchen wäre auch etwas dekadent.
Spaß beiseite - wenn du etwas programmieren kannst, ist so ein "einfaches" Schiebereglerpult schnell erstellt. Ich habe mal für Tests an einem DMX Kopfschwenker so eine Software zusammengestrickt - wenn du haben willst: eMail senden. Hat aber wirklich nur 8 Schieberegler...

Hallo MM,

Deine Frage ist sehr offen gehalten.

Ich nehme an, dass Du in Showtime bereits mit den DMX frames gearbeitet hast. Folglich gehe ich davon aus, dass Du den DMX-Ausgang auch "außerhalb" der Lasershows beliebig nutzen möchtest.

Wie John bereits vorgeschlagen hat, könntest Du ein einfaches (z.B. mit Visual Basic selbst geschriebenes) Programm nutzen, um die Werte der DMX-Kanäle zu ändern. Mit der bei Pangolin kostenlos erhältlichen API ist das kein Problem.

Dieses Programm könntest Du sogar starten, wenn Showtime noch läuft, so dass es gleichzeitig ausgeführt wird. Du solltest dann aber darauf achten, dass das Zusatzprogramm über einen Button "deaktiviert" wird, d.h. keine DMX-Befehle an die QM2000 Karte sendet, wenn eine Show gestartet wird. Ansonsten kann es zu unerwünschten Wechselwirkungen in der DMX-Ausgabe kommen.

Hallo nochmals

Jup, DMX Frames sind mir ein Begrifg (Greuel...) Möchte DMX Ausgang unabhängig von Showtime nutzen.
Auf dem Markt gibt´s ne Vielzahl von Anbietern die DMX Software vertreiben. Die Ausgabe erfolgt dabei meist über eine PCI Karte oder einen USB Konverter. Für mich stellt sich jetzt die Frage ob ich mit einer solchen Software den QM2000 DMX Port ansteuern kann (Adressierung etc. )

Wenn nicht werd ich mir wohl oder übel einen USB DMX Konverter zulegen müssen.

Andere Frage: Gibt´s eine Möglichkeit Showtime über DMX zu steuern. (mir ist nur der Umweg über Midi bekannt...)

Schönen Abend

Martin

Hi,

eine Standard-Software, die (auch) die DMX-Ausgabe über die QM2000-Karte unterstützt, ist mir nicht bekannt.

Da die QM2000 Karte keinen DMX-Eingang zur Nutzung anbietet, kann Showtime darauf nicht reagieren.

Hallo,

da mich noch jemand nach meiner Software gefragt hat, stelle ich das Programm mal hier zum Download rein. Ist wirklich nur ein Demoobjekt mit wenigen Umfang. Prinzipiell könnte man das beleibig aufbohren.

Hi All,

A few comments...

DMX "frames" are a very "different" concept. They are something that we came up with to address a wide variety of conflicting constraints. The idea was to allow people to be able who knew how to use Showtime, but perhaps did not know about all of the special things of a moving light, to still use moving lights (and other DMX-controlled equipment) in Showtime.

For example: how do you fade in a regular graphics frame? You drag the frame onto the timeline, along with a "fade in" effect. Guess how you fade in a moving light? Exactly the same way. Guess how you pan or tilt a moving light? The same way you do with a regular graphics frame.

In this way -- allowing people to use Showtime in exactly the same way they had been for years, but also have extra capabilities of working with lights, or beam projectors, or fog machines, etc. the concept of DMX frames indeed does work. HOWEVER, the concept of DMX frames will not compete with, or compare with, a dedicated light desk that was designed to "get your hands on" a large number of fixtures. Doing a show with more than around 8 moving lights in Showtime is possible, but it would be tedious, since each track in Showtime would be its own light fixture.

I have had a number of long conversations with laser and light programmers alike on the concept of DMX frames. I believe that the concept is successful for doing what it was meant to do, but it is not a "do it all". It can not be. But nothing can be. A lighting desk can not control lasers. The problem is that there are a lot of conflicting constraints, and so no one system will be good at addressing all possible DMX applications.

OK, well, regarding the comments of John and Dieter, these kinds of simple programs can indeed be created, and will indeed work along with Showtime. And actually I see no reason why it could not be used along with Showtime at the same time. The only thing to watch out for is if a DMX frame or DMX virtual channel (such as TTL or AUX out) are trying to control the same channel as the simple slider. In this case, Showtime will "over ride" the setting of the slider. But this is to be expected. In other words, I don't think it is strictly necessary to put a "disable" button on a simple program like this.

And lastly, actually the DMX port on a QM2000 is an input or output port. It can accept DMX input, or provide DMX output, but it can not do both at the same time. Low level software in the QM2000 operating system exists to accept DMX input, but this has never been "hooked into" Showtime, Live! or LivePRO. There are a few reasons for this, but the main reason is, every time I ask people to suggest a channel assignment or whatever, they "clam up" and stop asking. This is pretty frustrating, but this is how it has been... Anyway, if you watch closely, you will probably see a DMX-controlled laser option available from Pangolin soon...

Greetings,

Bill

@ Bill:

I didn't say that the hardware does not provide DMX input. I just mentioned that there is no DMX input that can be used right now.

Regarding access to DMX output by two applications at the same time, it depends on the way it works. If someone is using sliders on the screen only, I do agree.

The problem I had in mind was, if someone wants to use external sliders, connected to the PC's serial port for instance, it could happen that a slider is set to a value "between two clean slider positions". In this case, the slider would trigger a lot of SendDMX commands.

@ Dieter,

Yes, you are right about everything you said. And I knew that you knew the QM2000 can support both DMX in and DMX out.

I didn't say, that you didn't say that the hardware does not provide it <img src="/images/graemlins/wink.gif" alt="" /> Just adding a few details for those who did not know the capabilities...

@ Bill:

Yes you said, that Dieter didn't say that the hardware does not provide it (DMX-in). Because he says he didn't! <img src="/images/graemlins/grin.gif" alt="" /> <img src="/images/graemlins/laugh.gif" alt="" /> Got my point? I think you meant it the other way around. <img src="/images/graemlins/wink.gif" alt="" />
