Navio+ with I2C airspeed sensor issue

I’ve just set up my Navio+ with ArduPlane but can’t get the board to read from the airspeed sensor. I’m using the Pixhawk airspeed sensor 4525DO:

I’ve just plugged the sensor straight to the I2C input and hoped that the board would recognize it, but no such luck. I’m assuming that the Airpseed pin for I2C is the “… MEAS I2C AS”, I’ve tried the other as well. Has anyone used this sensor successfully on Navio/ArduPlane? Or is there a compatibility issue here somewhere?
