They should work with any other DMX device but to set the channel range then these need to be done one at a time and not connected together.
Ive used a few of the DD100 controllers before and these could be used with other devices, but the way they worked was that they stripped the data signal from the channels it used, and then the remaining data signal was starting at channel 1 again, so then every controller thinks it starts at channel 1.
So if you use more than one of these in a universe then they all should be set to start at channel 1, so controller 1 may be channel 1,2,3 and 4 and then controller 2 would be channel 1,2,3 and 4 but in the software it will actually be 5,6,7 and 8 because the first 4 channels were stripped from the data stream.
Anyway thats how the DD controllers worked so this may be the same way the DM controllers work
