Master / Slave Revo 4 and Fusion Tri FX Bar 2

Hi Guys

I thought I knew the answer to this one, but a dealer has got me thinking, hence the post!

I was previously under the impression that only like for like lights were able to be master / slaved together. However, a dealer told me that I shouldn't have any problems master / slaving my 2 Revo 4s with 2 Fusion Tri FX Bar 2s I've just bought. That is, using one Revo 4 as the master, then the other Revo 4 and the two Fusion Tri FX lights as slaves. He said that "similar" lights from the same manufacturer could successfully be master / slaved. So a Revo 4 could be master / slaved with a TriFX Bar 2 but not say, with an ADJ Par Can.

So my question is, would it work?

I've also a couple of Tri Fx lights (which are master / slaved to each other) and he said that these two could also (in addition to the above) be slaved off the first Revo 4.

Thanks for your anticipated advice!
