Section Introduction Scope This manual provides detailed installation, calibration and operating instructions for Trans-Cal Industries' Model SSD120-35C-RS232 series of altitude encoder/digitizer. This manual assumes use by competent, qualified avionics professionals utilizing installation methods in accordance with 14 CFR and other industry accepted installation practices. Equipment Description Approved under FAA TSO-C88a and EASA ETSO-C88a the Model SSD120-35C- RS232 is an all solid-state electronic device which, when connected to an aircraft static and electrical system, converts pressure altitude information into parallel and serial digital data.

10 The parallel digital altitude data protocol is set forth in the ICAO International Standard for SSR Pressure Altitude Transmission. In accordance with National Standards for Common System Component Characteristics for the Mark X. (SIF)/Air Traffic Control Radar Beacon System SIF/ATCRBS. The serial altitude data is provided on (2) two asynchronous RS232 outputs. The serial data protocol is selectable and may be used to provide pressure altitude data to GPS or other on board navigation devices.
