Directly via programming. Reading the channel is good. The only problem is that the box gets very hot. Can be a problem when placed on delicate furniture. Edit: It hasn't been a year and the device is dead. Maybe it was the heat. I do not know. I don't see any spare fuses. Not a bad unit as long as it worked. I think you get what you pay for. I think for now my rating should be three stars (generous) and that would be the price.
