Din Analogue to DMX adapter?

[Jupton24]

Ive recently come across some analogue dimmers where I work and wondering if such thing exists as a din analogue to DMX adapter? or am I worth binning them? I should of thought such things dont exist but it would be great if you could point me in the direction of one. 

Thanks

din analogue to DMX adapter

the magic adaptor is called a d-mux for example  https://www.thomann.de/gb/showtec_multi_exchanger.htm

Try "demux" on a well-known auction site.

You should be aware that there a few different standards for analogue dimmers, the most important of which is whether they require a positive or negative control voltage. Some demuxes can drive either, and some dimmers can accept either but if you try to control a -ve only dimmer with a +ve only demux it won't work.

Good point Dave. +10v is the usual, but old Strand dimmers used -10v, & not all manufacturers used the same pin numbering. An indication of the make & model (& preferably a photo or two) would help.

Actually, I think you’ll find the OP is asking for an analog to DMX adapter, which would be a multiplexer such as this 😛

Although your link would probably work better for what they really want to achieve…!

@Jupton24 , if you can tell us what the make and model of the dimmers is, we could provide some better guidance with regards to @DrV’s comment

yea all depends how you read the question

seems to suggest  they want to get them to work  on DMX

Sorry, maybe I should have included the <pedant> tags in my reply...Now where's that IEC to 13A cable to plug my desk in...😛

As other folks have said - if you want to control analogue dimmers from DMX then there are some options available - the easiest of which is the Showtec Multiexchanger - it will drive dimmers that need positive or negative going control voltages. The only PiTA is that the outputs on the unit are 24pin D connectors so will need some soldering to make up adaptors (or buy them from 10 out of 10).

If you want a really compact way of doing it then there are some "new build" 6 channel PCB units around that would just need a small case, have a look on eBay.

Some years ago I bought a couple of Ben Suffolk's units which can be found on this page;  they were easy to fit and the dimmers are still in use.

Thanks for the advice. Here are a couple of pics. The first pic shows the connector.

The hardest bit being the 25 pin  d sub,however you can make life a bit  simpler by buying a fully wired 25 pin to 25 pin lead and chop it in half

[sandall]

Hmm, don't recognise the dimmers & there's nothing shown of the polarity & pinout of the DIN socket. Can you find any form of lighting desk that went with them?

[Andrew C]

I remember Eltec.  Their memory desk could be configured + or -.  Doesn't help much I'm afraid.

[timsabre]

Eltec were 0 to +10v. I would expect it to use the "standard" wiring which is pins 1-6 = chans 1-6, pin 7=12v, pin8 = gnd. You can test this by checking pin 7 with a meter.
