1 GENERAL INFORMATION
1.1 Introduction
The information contained within this Installation Manual describes the features,
functions, technical characteristics, components, approval procedures, installation
considerations, setup procedures, checkout procedures, and instructions for
continued airworthiness for the Sandel Avionics SN3308 Navigation Display. The
SN3308 is available in several dash-number configurations depending on installation
on pilot’s side, copilot’s side, or center panel. In the manual any reference to GPS
receivers is generic and can be applied to Loran receivers.
1.2 Equipment Description
1.2.1 Features
The Sandel SN3308 Navigation Display is an advanced microprocessor controlled
airborne multipurpose electronic display which is FAA approved under technical
standard order TSO-C113. The SN3308 employs a patent-pending active matrix
liquid crystal (AMLCD) projection display. It is designed to combine the functions of:
x Horizontal Situation Indicator (HSI)
x DME Readout
x Marker Beacon Indicator
x WX-500 Stormscope® Display
x Long-Range Navigation (GPS or Loran) Map Display
x GPS Annunciators and External Mode Switches
Outputs of heading and course datum and bootstrap heading output are provided.
The versatile digital and analog interface properties of the unit provide for
compatibility with most VHF navigation receivers, ADF’s, DME’s, GPS’s, remote
gyros and flux gates.
The SN3308 is designed to display the downloaded flightplan data from a connected
GPS receiver or from a Jeppesen database (available on software version 2.00 or
later). The moving map database for the SN3308 as well as the internal operating
system software are field uploadable through the use of a portable computer
equipped with a Windows operating system and an RS-232C Serial Port.

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 SN3308 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 SN3308 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.
In addition to connecting the desired equipment, the installer must provide the
following components:
x Dimmer Control
An external pot must be mounted near the SN3308 to provide for
convenient dimming of the display. This is not a rheostat, it is simply a
10K, ½ Watt pot which provides a control voltage.
x Data-load Port
A ¼” phone jack must be installed in any convenient location and wired to
one of the SN3308’s serial input ports, as shown on NAV-2,GPS1(RS422),
GPS-2, DATALOAD Installation Drawing. This port will be used to upload
new software and database revisions.
Refer to the installation schematics at the rear of this manual for details on connecting
these two required components.
The installation planning cycle is summarized as follows:
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.

90106-IM-G(4) Installation Manual W SIG.doc Page 10
The post installation procedures are summarized as follows:
1) Prior to power-up review correct wiring by using standard ohm meter and
voltage checks . Insure the correct orientation and positioning of the three
SN3308 ‘D’ connectors. The connector numbers are printed on the back
of the SN3308 for reference.
2) Review special items such as connection of the Nav receiver resolver
wiring.
3) Apply power to the SN3308, bring up in maintenance mode (see page 41)
and sequentially access each SN3308 maintenance page to correctly
select the installed equipment.
4) Allow the unit to operate for 30 minutes at maximum brightness and check
the internal temperature readout on maintenance page 17 for an
approximate temperature rise of approximately 10qC or 18qF. This
checks proper cooling airflow.
5) Perform Ground Test procedures
6) Perform Flight Test procedures.
1.4 Interface Planning
1.4.1 Compass System
Determine whether the SN3308 is to be used internally slaved or unslaved.
Unslaved operation would be appropriate when the SN3308 is bootstrapped to an
already slaved compass system or is being slaved to a panel mounted XYZ DG.
Plan for:
 High Resolution Digital Output from a Mid-Continent 4305 series DG with
compass valid output, flux gate 10 VAC Fluxgate Excitation and Internal
26VAC Inverter
 Quadrature stepper motor drive input from a Bendix/King KG 102 series
DG with compass valid output and flux gate support,
 3-wire ARINC 407 synchro DG with or without compass valid input and
fluxgate.ARINC Low Speed 429 Heading Input. Sandel monitors for Label
320, Magnetic Heading Data and Label 270 System Status
