Mike I keep reading what you wrote, but how can you tell the difference? The Band data is the only thing that the KPA500 requires to operate. It really doesn't care about the exact frequency.
If you change bands on the 6400 and the KPA500 tracks from 1 band to another, then your installation is fine and you should be good to go. I used a KPA500 for years on a Flex 6300 without issue. For cables, all that is required is a normal 9 pin male-female cable and then a Null Modem Gender Bender adapter (yes, that is what they are called).
