Interesting info about the $6 3ch DMX controller

[dmoore]

Some may have followed my mass deployment of the $6 DMX controllers.  I started looking a little closer and two things popped out - one is that there is a WS2801 chip on there - why would there be one in there?  Second is that it uses a Texas Instruments RS485 chip, not some cheap Chinese knock off.

Attached is a datasheet for the TI 485 chip and so photos.

Here is a video of 46 of them on a 250ft cable with 90 splices:

Great Video and original frames...

I like this kind of inventive solutions....

Technology is here, so no limits... Maybe our bullet as usual

Nice video David.  I want to now what was burning in on the bench to the left though.  Was that a coroflake or two?

Jeff,

I believe what David is using (correct me if I'm wrong David) is the following:

"DMX512 Dditor for setting DMX address;P/N:LN-DMXID-EDTIOR"

Just a note...you can have Ray set the addresses when you order them so you dont have to buy the editor....I only have like a dozen so that is what I did.   If you are getting a bunch of them, I'd probably buy the editor.

The link above is correct for the editor.  Of course these $6 DMX controllers are like pringles - you can't just buy 12!

and of course somewhere down my to-do list is to add programming the start address for these devices as a web page option in the ECG .....

I bought several of the controllers and one of the programmers so I can figure it out.

That sounds exciting!  I love these little boxes for de-centralized control, it's hard to imagine that the DIY community could even produce them for personal consumption at the price that they are sold (with the wires and mounting box).
