Hobby Boards Barometer

[ultrajones]

I have an EDS OW-SERVER connected to a HobbyBoards Barometer. The OW-Server detects the device, but the readings certainly don't look like the current atmospheric pressure (currently about 30.03 according to WeatherBug). Can any of the values below be used to calculate the actual atmospheric pressure?

VAD * slope + intercept = atmospheric pressure
