The SSD120-35C-RS232 is a rugged and reliable altitude digitizer for applications where size, weight, and economy are critical. This encoder accurately measures air pressure and converts this measurement into the ICAO parallel data as set forth in the International Standard for Pressure Altitude Transmission.
Incorporating one ICAO gray code port and two RS232 serial altitude data outputs, this encoder is a simple and robust addition to any avionics installation requiring pressure altitude information for multiple aircraft systems.
The serial data protocol is commonly used to provide pressure altitude data to ADS-B, GPS, auto-pilots, transponders and other navigation devices. Six serial data protocols are available. Data protocol is selected through internal shunts or via software set-up.
