Thanks for the info guys. Sorry to be such a grump, but I just had it today trying to get the thing programmed. Now it's giving me some communication error, wherein I can't upload the file from the remote to my laptop. But, the connection works insofar as when I use the 'test" button in the program on the laptop (to see if the signal works) the remote gets the command thru the USB-serial-miniplug cable and tranmits. So, I don't know what the deal is. My patience rapidly reaches its limit with stuff like this. I flew the F-16 for 14 years and it didn't frustrate me like this thing does. You'd think if I could handle that, I could figure this thing out. LOL.
