1.2 PRODUCT DESCRIPTION
The AR850 Altitude Reporter is a TSO'd pressure altitude
digitizer. Sensing atmospheric pressure, the AR850 converts
pressure/altitude information into digitized altitude data, ready
for transmission to air traffic control centers via the aircraft's
transponder during a Mode C interrogation.
The AR850 L/C (30,700 ft.) differs from the 25,000 and 30,700 ft.
versions in mechanical packaging and altitude limit only. The pin
out (because of the smaller connector) is different from the
original model. The electronics remain the same.
The AR850 L/C (30,700 ft.) is not pin compatible and requires
different mounting holes than Narco's older AR500 Atltitude
Reporter.
