Borgelt B40 averager
Does anybody know which sort of signal goes from the
Borgelt B40 vario to the external averager? Is it just a voltage or something more complicated? The reason I want to know it is that I'd like to make up my own display instead of buying the original one which is rather bulky. The only alternative would be to buy the small display for the B400, but are they compatible? Any comments welcome. Mike

The logic person to contact is Mike Borgelt, you can get his email address from his web site. I've always found him to be quite helpful with questions like this. The signal from the B40 is analog, I believe it swings +/- 1V (+/- 10 kts or 5 m/s) from a 2.5V reference. I believe the same signal is used for the repeater, so the averaging is likely being done by a separate circuit in the external unit... Marc

our B40 has a built in averager, only displayed when the button is
depressed.. would not that voltage be reported to the external averager for display? Granted I think the external averager is digital display BT "Marc Ramsey" wrote in message t...
