Chamsys board

Hello, need some help about this issue, recently we use a grandma network connector, to connect a chamsys board, so the desk could control the nsp, the question is if whit a hog4 we can do something like, or the chamsys board can control the dp 8000 in some way. It is for a festival and the venue provides hog4 but the show is actually runing on a chamsys.
