Reel FX DF-50 Hazer

[metraflex]

I am trying to operate a Reel FX DF50 hazer from our Frog 2 console. The Reel FX web site describes the DMX option of the DF-50 to be a single address to provide proportional control. How do I set up the console to recognize the DF-50 and apply this simple control? I do not see the DF50 in my fixture list.

Thank you
