Full Version: What Is The Best Way To Connect My Impossibled's And Miracled'

After a bit of buying and selling, I now have an overhead LED lighting rig Im really pleased with, consisting of the following:

2 x Impossibled's
2 x Miracled's

I know that LED lights are not everyones cup of tea, but the reliability and weight were the factors that appealed to me!

I've had a play around and will probably display them either on 2 T-bars (one either side of me), or all 4 on one T-bar with the Impossibled's below the bar and the Miracled's above the bar, both set ups look good!

I know I can run both lots of lights in master-slave, but does anyone know if I can connect them all together to produce a "combined" light show? (in the same way you could connect Abstract lights together in the old days, such as Gladiators and Galactic Moons etc).

I don't know much about DMX, is this the only option?

If anyone else has any ideas how to get the best out of these lights, please let me know ;O)

At the moment I am running them with each pair connected together, running programme "0" - this looks great but Im wondering if I can make it look even better!

Cheers,

I asked this in a shop back in March, exact same question about the exact same lights. I wanted to control the lot with a CA-8 but he said it wasn't possible as the 2 lights had different amounts of things you can control. For example, lights, gobos etc.

How true this is I don't know. Maybe you should email Prolight and ask them.

Thanks DX, I have taken your advice and emailed the technical engineer. I will let you know what he says!

Both types of lights have different DMX addressing/channels, and I don't think they'll be compatible with each other. But you can only ask the manufacturer! :) When you think about it, both types of lights are quite different to each other.


Best you can probably do is link each of the lights of the same type together then use separate hand-held controllers for each.

Not sure what you use to play in your music but if you use or have a laptop why not get freestyler and a vellerman dongle from maplins and DMX them you can do many more things with them when set up like this.

Freestyler as its name suggests is free to download and the dongle from maplins is £59.99 Click me

You may have to build the dongle though. Thats what I did it is quite easy to do.

There is that option too.

I bought a Velleman USB DMX controller initially, but found it slightly slow (for my uses). I've replaced it with an OpenDMX controller. The Velleman is now redundant and I dont use it anymore (useful for backup though).

Interestingly, the OpenDMX controller was about 15 quid cheaper than the velleman. Its also smaller (as its all integrated into the USB plug).

I have not noticed the unit being slow. How do you mean and was that with Freestyler or the provided software.

Slow as in latency.

Hit a flash button, and then quite noticably the fixture will actually do what it was told by freestyler.

Also if you send the same DMX control to 5 led fixtures at the same time (like strobing on off really fast), some fixtures seem to miss their channel change.

Another example where its too slow is where I've been uising the DMX400 chaser, and chasing LED fixtures 1-4, you'll sometimes see that if its fast enough chasing it will "miss" out every so often so the chase looks broken. (Freestyler Output is correct though).

More info here on the DMX wiki (which is quite good I've found):

http://www.thedmxwiki.com/dmx_usb_interfac...man_vm116_k8062

The key bit being:
CODE
This interface gets slower, the more DMX channels are set to a higher value of 0. When all 512 DMX channels are set >0 then the VM116 takes up to more than 600msec to receive its information via its USB connector.



There are options in Freestyler to make it work better though - Limit output to 96 channels and set the refresh as low as possible (20ms).

Hi dave thanks for that. I have mainly used it with FS for shows so mostly just the odd lighting state change now and agin so probably why I have not noticed it so much.

I was doing sound for a band though that used the vellerman but the guitar player wrote his own software for the DMX and it worked perfectly.

Have you used the MyDMX software and dongle.

Sorry if I have kidnapped this thread some what but it is all DMX related and hopefully the OP might find it usefull.
