All I can is WOW, what a brilliant product the USB IF232 CAT Interface is. Tried using another product from another vendor on Win7, it wouldnt play ball, yours straight out of the box, found its own driver.
I will be recommending you too everybody that asks about the computer control.
Very happy here in Australia and only a 11 day wait from the date I ordered (and its Christmas mail time)
Merry Christmas from down under
