I'll be starting the programming in a few days. Just wanted to confirm that I could set up IF/ELSE statements that could check whether the HR20 was on or off. I'm a bit confused about one thing. I'm sure the MSC-400 video sensor will know when the HR20 is on but will it know when the box is off? I've read some reports that the HR20 still buts out video when the box is off. If so, how would the MSC-400 know its off?
