Martin Magnum 650 Smoke Machine Re-Wire For DMX On / Off

[ozzytheman]

Hi,

 

Would it be possible to re-wire the remote on my martin magnum 650 smoke machine for DMX, might need a DMX relay pack? Any help greatly appreciated. Thanks

A DMX relay sound like the easy solution. So long as you only want on/off control.

 

Edit - OK, that is all the remote offers.

Andrew,

 

So there is no circuitry I could add or anything so I could assign a channel for smoke trigger on / off? Turning the device itself on for warm up via switch is no problem. Cheers

Assuming competence on your part, build a replacement controller with the internal switching replaced by a DMX relay pack - look for one with a set of volt free contacts. Then power up the machine in the usual way and control it by DMX from the desk.

Jivemaster,

 

Just slightly confused, by DMX relay pack you mean one with iec connections? Thanks,

I'd be looking at http://www.milinst.co.uk/ hit the index for DMX controllers and chose one of the plain board controllers, Put it in a box and have DMX in and out and relay out to the smoker, you will need 12v from somewhere too.

Jivemaster,

 

cheers. would I need the 'DMX relay board' then without the casing ? thanks

Everyone

 

Just want to say thanks, bought the two channel DMX relay, soldered into the controller & all works perfectly one a single DMX channel. Cheers for all your help! Thanks

Hi chaps, digging up an old thread here as would also like to do this to our Martin Magnum 650.

 

I have had a look at the Milford Instruments page and have been looking at the single channel DMX Switch - Linky.

 

I was looking at making a box with switch, 12V transformer, neon light (Linky) and DMX sockets on. We hire this unit out occasionally so would like to retain the orginal remote, was looking at using IEC C19/C20 (Linky) connectors so as to make it difficult plug the wrong thing in.

 

My question is how would the wiring go to wire IN and OUT DMX sockets to the switch, I believe pins 2 and 3 from both male and female would connect to the appropriate screw terminals, Is this correct? Or would it be easier to use the 2 channel switch, as this has DMX sockets mounted on the board already? I only favoured the single channel as mounting the switch in the box would be less critical and I can use Neutrik panel mount connectors.

 

Could anyone suggest a small 240V - 12V 500mA transformer I could mount inside the box? I would then fit a standard IEC panel mount connector on the box. Would it be wise to fuse this connector?

 

I have a IP66 plastic box here at the day job that would fit the bill perfectly. I was going to add the neon light to the outside of the box, in the hope that I can place the box somewhere I might be able to see it from the desk. If I leave it out then does it matter if I activate the switch when its heating, as there would be no way to tell if ready or not?

 

BTW I am competent with electrics, as the day job is mainly electrics, albeit electro hydraulic systems! We have an electrician we use who will PAT test for me.

 

Thanks in advance!
