Control Lighting
-
Raha's points about "jumpy and bumpy" must be emphasized. I bought a cheap-o LED light to do testing with Isadora, and was shocked by the "stair-stepping" as I did a fade. Very ugly!

Thanks for your detailed post @raha.
As many of you know I have used Isadora for many years now but lighting has always been one area that I know little about. My new job is very keen for basic interactive lighting so I have been reading up about it.
From what I can gather I need a Entec USB pro and then from that one DMX output I can connect it to 6 lights (daisy chained) and then fade one of the six in and out when one of six videos is chosen.
So:
Isadora>Entec>LX1>LX2>LX3>LX4>LX5>LX6
How does Isadora talk to the Entec box is it serial?
LX1 - ch1 - 4
LX2 - ch5 - 8
LX3 - ch9 - 12 and so on....
Thanks!

Hi Skulpture
You probably will want to use the entec actor found here: http://forum.troikatronix.com/cgi-bin/forum/gforum.cgi?post=9813;search_string=Enttec Lanbox MATRIX;t=search_engine#9813
The USB pro uses serial over usb, so you will need to setup a serial connection.
With the 1 universe you should be able to chain many lights. 6 for sure. It depends on the nuber of control channels per fixture. If its a rgb led fixture it will likely have 4 channels, 1 for Red, 1 for Blue, 1 for Green, and 1 for Brightness... some will have additional for things like strobe features etc.. in the case of 4 channels per fixture you can connect over 100 of them to your single universe controller.
If all lights are the same then addressing will likely be... Fixture1: ch1 brightness ch 2red 3green 4blue , Fixture2: ch5 brightness ch 6red 7green 8blue , Fixture3: ch9 brightness ch 10red 11green 12blue.
Each fixture will have a dip switch that you have to set to its first channel. So Fixture1 will have the dips set to 1 (they are in binary.. often a chart is supplied) Fixture2 dips set to 5 and fixture 3 dips set to 9 etc..Hope this helps.

That helps a hell of a lot! Thanks.
They will be basic spot lights so no RGB (hopefully) just "Warm White" I think they describe it as.I for some reason thought I'd need a dimmer pack or something? I think i'd need one if I was using 240V lights am I right?Cheers again and Ive downloaded the patch. ;-) -
Dimmer pack.. maybe.. depends on the lights.
If they are incandescent and don't have built in DMX dimmers you will need one.
The addressing on them is pretty straight forward. Again it would have a Dim to set.. and then usually one dmx channel per output. -
Please note that the patch found in the old forum doesn't run smoothly on newer releases of Isadora. Please use the patch attached here which has fixed the problem. Mark is also working on a fix that will make the old patch work again.

Wow brilliant! Thanks @CraigAlfredso

@CraigAlfredson
What changes were made? I added a trigger-text actor and a control pulse to the old one and had it running perfectly last weekend. -
Ah... sorry I should have opened the new patch first.. Looks like you made the same changes.
Did anything else get updated?
-
That is the only change from the old one. Mark is working on some other changes that will hopefully be in an upcoming release.

I have just found this very useful....

@Skulpture
Yeah.. I found that when getting started to. Pretty useful. -
Hmm... I wonder what Mark could be upto.
Intrigued. -
@dusx huh? confused

Dear Craig,
Given my addled brain, maybe you can remind me what I said I was going to do. ;-)Best Wishes,Mark -
i have just purchased a Enttec DMX USB PRO and some LED, I was planing to test out the setup using isadora ,wondering if anyone got a simple patch i could use?
-
Im trying out my new DMX USB PRO with isadora for the first time. I tried to use CraigAlfredson´s Enttec Lanbox MATRIX v1.3.izz 52K patch, but when I open it I get a serial port error saying that my serial port could not be activated, I guess that this has to do with some drivers i dont have. Has this problem ever occurred to someone and does anyone have any good tip how to get around the problem?
-
I havnt ever played with one of these things, however heres a couple of things to check out,
go to communications > serial port setupdetect serial port, bottom left or manually choose it,can you see the port your plugged into?when selected is it red and busy? if so it could be in use by another program if so close it down.or could be a driver issue.theres a couple of things to try.hope that helpslanz -
hi lanz and thanks a lot for the reply!
yes it is plugged in to port 1 and the red typing saying usbserial-EN084669(Offline)im not using any other programs so it cant be that.it doesn't pop up in the Finder > devices menu either when i plug it in.do you know about any trick i can try.b.wasle -
Hello aslelp,
The red typing you see is the left-over ID from my Enttec device. In the Serial Port Setup window, hit Detect Serial Ports and then click the Select button under Port 1\. You should see another device with a similar name; select it and all should be good. If you don't see that, then there is a problem with the drivers for the Enttec.You need to install FTDI drivers fro the entecc, available at http://www.ftdichip.com/Drivers/VCP.htm. If you continue having trouble, try downloading the free version of Mini Stage Console from ChromaKinetics here:http://www.chromakinetics.com/DMX/miniStageConsoleMac.html.It is a good little program that I use to troubleshoot DMX issues.
