DMX - what is needed (the basics)??

posted Sep 17, 2012 06:24:21 by PirateGent
First - thank you to Thom for making this awesome simulation and continuing to make it even more awesomer (yeah I know it's not a word but if fits!)

I've seen in other posts the link to items Artemis now supports
ENTTEC Open DMX USB Interface;
http://www.enttec.com/index.php?main_menu=Products&pn=70303&show=description
This small box costs $65us, and interfaces between your USB computer port and one or more DMX devices.

http://www.interactive-online.com/what-is-dmx
http://www.guitarcenter.com/Color-Changers---Wash-Lights-Lighting---Stage-Effects.gc

But my question is - besides the DMX interface and the LED light(s?) what is basically needed (want to make as few orders as possible)

If I remember seeing the videos it looked like there were two sets of lights on either side of the main screen but beyond that - do you need cables? And if so - what type? Extra power strips? Anything else?

My Star Trek group is hosting an Artemis game at our local library for Star Trek TNG's 25th Anniversary at the end of the month and I just wanted to make sure I had everything I need (and tested) to give everyone their best experience.

Thank you all in advance.

The LEAST configuration would be

1) an ENTTEC Open DMX box

2) A 5-pin to 3-pin DMX cable adaptor (very important!)
http://www.enttec.com/index.php?main_menu=Products&pn=70029&show=description

3) a dmx light

4) a dmx 3-pin cable

DMX is designed to be daisy-chained. More lights and more cables can always be added.

Thanks!

Okay - follow up crazy question... (mainly because the above items didn't come with many - if any manuals)

I've got my Open DMX box - plugged into USB and 5 to 3 pin converter. Plugged into 3pin DMX cable plugged into Chauvet PAR 38 DMX LED

Drivers installed.

Light plugged in - changed it to CH 7 with program d506

boot up Artemis - test raising shields, docking and red alert - nada.

Light does work (when I cycle through the channel set up)

Suggestions, thoughts, other? (any help most welcome - setting up Artemis NEXT WEEKEND at local library for the public - using to promote "Star Trek Day")

Really want to wow people with what this game can do.

Thanks

I haven't added lighting yet, but have been watching the forums VERY closely. Is it possible (from reading other posts) you're missing a "trigger" file? I read Artemis supports DMX. I read that you've set up lights. But is the "hook" included that tells you what light to fire during what event?

First, do 3 channel, not 7 channel. 3 channel is what I use.

Second, understand that dmx sends 512 bytes to the lights, and the lights use only the bytes they need. My included dmx event file assumes the lights are set to use byte 0, 1, and 2, for red, green, and blue lights.

SUCCESS!!!! (at least with one light - will test two at the big day at the library on Saturday.)

Channel 3
program d 1

Looks like it did the trick.

Lights changed for docking, shields, red alert & incoming fire!!!!

Thanks to everyone for their patience with me.

Did you get it to work with two lights?

PirateGent said Oct 02, 2012 23:36:37
Yes!!! Just daisy chain the lights

I have a flashing light that I'd like to have for red alert. It's got a switch on it and plugs into the wall. Is there any way I can set it up with DMX to apply power to it when red alert sounds?

I don't necessarily want to get extra lights. All I'd like it to do is turn on the power to the plug when it's activated. Is there any way to do this?

Perfect write-up Thom; ordered my gear today; hope to put into place by next weekend -- for our second run of the TSN StarKindler.

Looking into doing this for our group as well, has anyone tried this USB-to-DMX dongle?
The adapter linked by ThomRobertson looks good, but if the less expensive option works ($85 vs. $42), saving a buck here and there adds up to an additional light or two in the long run.

I found the recommended model for $63.68: http://www.sirs-e.com/st/enttec-open-interface-p-5277.html. TY to Entec for pointing me to their distributor list as their 'direct from manufacturer' store was out of stock when I ordered last week.

I would like to see support for the Ethernet Open DMX as well.....

With the Slim Par-38 above, the RBG is 1,2,3. I modified the DMXcommands.xml file replacing the "2" with "3", "1" with "2", and "0" with "1". This resulted in a fully functioning system. I was able to test it using a single workstation running the server /w the light rig; and a 2nd application instance as client, then also, from a remotely connected IPAD.

Very sweet. Now, I must buy more lights and figure out how to setup a separate flashing light for red-alert and a white-blue toggle for shields.
