Sandia Aerospace SAC 7-35 - Manual (Page 5)

Section 1 General Description
1.1 INTRODUCTION
This manual describes the installation of the SANDIA aerospace SAC 7-35 Airdata Computer. It is
intended for use by FAA certified repair stations to install the SAC 7-35 Airdata Computer and in-
cludes both the mechanical and electrical installation information for the SAC 7-35. Calibration, sys-
tem configuration and checkout procedures are included. The installer should ensure that all functions
are operating according to their intended purpose in their particular installation.
1.1.1 Product Description
The SAC 7-35 is a solid state -1000 to 35,000 foot airdata computer and altitude encoder. With the addition
of a fuel flow transducer(s), the SAC 7-35 will also provide fuel flow data to systems capable of displaying that
information. The SAC 7-35 provides five data outputs that allow it to interface with a wide range of transpon-
ders, TAWS, MFD’s, Navigation Systems and a variety of other avionics products. The SAC 7-35 can also
be installed for use in a variety of converter functions. Contact factory for more information.
• One ARINC 429 High Speed output, airdata and/or ADS-B.
• Two RS-232 airdata output ports (including fuel flow or ADS-B).
• Two RS-232 serial encoder outputs
Note: All four of the RS-232 outputs can be individually configured to match the system(s)
being interfaced.
• One Gillham Grey code output for legacy transponders.
• One SANDIA Altitude In-flight Monitoring (AIM) feature. With the addition of an optional
panel mounted switch and annunciator the AIM mode will monitor and advise the pilot if the
aircraft deviates from a selected altitude.
All calibration and configuration is accomplished via a lap top computer through the 6 pin Din connec-
tor on the front of the SAC 7-35.
