The SSD120-(XX)N-RS232 & SSD120-(XX)NE-RS232 are all solid-state Altitude Encoders. These devices provide a rugged and reliable means of measuring air pressure and converting this measurement into the ICAO parallel data for Pressure Altitude Transmission.

These units also provide altitude data on two asynchronous RS232 outputs. The serial data protocol is individually selectable for each output and is commonly used to provide pressure altitude data to ADS-B, GPS, Auto-Pilots, Transponders and other navigation devices.

Resolution of the serial altitude data may be set to 100 feet or 10 feet. A data protocol offering one-foot resolution is available, as well as one protocol offering altitude data in meters.

This device is available in a variety of configurations based upon the operating altitude, temperature range and data formats required.
