You must be a new user with VU + box.
A few years ago I've made something like with my remote from DM7000
However after a month I have not used anymore DM7000 remote
because I'm used to VU +.
That is smaller and better lies in your hand when you get used to the position of buttons.
There was one group that rules the program for the remote

I think they were thread on the VU + support forum
so look there.
But that was a few years ago
I have no more that program and information.
