Hi Bob,
I'm running 3 x SDI mojo systems (2 x PC and 1 x Mac) and 1 x Mojo DX on a Mac.
I've attached a photo of the RS-232 to 422 adapter. Only one of them was labeled with anything at all and it seems to say 'Data Mate'. The other 3 are just plain black. They cost me $150 each but then again, my local rep charged me $12k for the DX upgrade and 3 months later is now selling it for $7k... so I could well be paying waaay to much for these.
The 'UUU' and 'http://WWW'labels are just labels we put on so we know which end is which. Sorry 'bout the blurred image... iphone.
Hope this helps.
