RS-232 (A & B) Airdata
The airdata outputs supported by the SAC 7-35 are Garmin Z-message, Garmin-G and
King D. Each of these output formats work with ‘Aviation’ format input.
The SAC 7-35 will also interface to a Garmin ADS-B serial output on port -B at 9600
baud. When connected to ADS-B input no serial data is output on port-B.

1.2.3 Operating Limitations
1.2.3.1 All functions of the SAC 7-35 meet the appropriate design assurance qualifications for a
secondary system for airplanes in Class I, Class II and Class III in accordance with AC
23.1309-1D, Figure 2. The TSO authorization with the RTCA/DO178B software levels by
functions are listed in Section 1.2.6
1.2.3.2 The SAC 7-35 is for navigation information only and not for primary flight information.
1.2.3.3 Fuel flow limited to 2000 input pulses per second.
The SAC 7-35 fuel flow conversion is limited to 2000 input pulses per second
For example, do not install where the K factor and maximum fuel flow exceed:
500K — 14,400 gph
19700K — 365 gph
84600K — 85 gph
130000K — 55 gph
