Dataflash Control?

I have 2 old dataflash units with SO lamps. (these are NOT AF1000's) They have 3 pin xlr's for "data in" and "data out". My question is did the Dataflash units ever have the option to be controled via dmx from a console? The website only has 2 manuals. One for AF1000. And a second for the original Data Flash product that has 1/4" data in and out. So I'm hesitant to jam dmx in them without knowing what I have here.

If photos will help let me know.

Thanks.
