The SSD120-(XX) Series High Altitude Nano Encoders are all solid-state devices that measure air pressure and convert the measurements into the ICAO parallel data for pressure altitude transmission via ICAO pressure altitude Gray Code output. These Nano encoders also provide altitude data to ADS-B, GPS, transponders, autopilots, and other navigational devices with two asynchronous RS232 outputs for which the serial data protocol can be individually selected. The user has multiple resolution settings to choose from. Typically, the altitude data is set to 100 feet or 10 feet.
