General Information
82005-IM-K Sandel SN3500 Installation Manual Page 1-2
Outputs of heading and course datum and bootstrap heading output are provided, as
well as L/R and U/D deviation output and flags. The versatile digital and analog
interface properties of the unit provide for compatibility with most VHF navigation
receivers, ADF’s, TACAN’s, DME’s, GPS’s, remote gyros and flux gates.
The SN3500 is designed to display the flight plan data from a connected GPS
receiver. The moving map database for the SN3500 as well as the internal operating
system software are field loadable through the use of a portable computer equipped
with a USB port and a USB capable version of Microsoft Windows.
Although simple, retrofit replacement of most existing three-inch PNI’s or HSI’s is
possible without additional features, we strongly encourage complete installation of
the unit with all compatible peripheral equipment interconnected to maximize its
functional capability.
1.3 Installation Planning
Sandel Avionics has taken many equipment interface possibilities into consideration
during the design of the SN3500 to ensure maximum interoperability with other
avionics. Contact the factory with any questions about interfacing to specific avionics
equipment not covered in the installation drawings.
To simplify installation and installation planning, signals are wired to the SN3500 pins
per the installation diagrams and software setups are used in a post-installation
procedure to assign protocols/gradients to each pin based on the equipment
connected. There are separate maintenance menu pages for each equipment
function and in most cases the selections are made by equipment make/model.
1.3.1 Installation Planning Cycle
1)
Compile an equipment list for the aircraft.
2)
Study the feature list below, and determine the desired functional
characteristics for the installation.
3)
Study the installation drawings to determine a basic interconnect scheme
and check for conflicts.
4)
Develop the specific wiring diagrams unique to the aircraft.
5)
Assemble required tools. Recommended crimp tools are given in the
following table.
