1.2 FUNCTIONAL DESCRIPTION
The Multilink Surveillance System (MSS) is a family of products that provide varying levels of
functionality over a range of General Aviation (GA) aircraft (based on aircraft performance and owner
preference). The levels of functionality that can be provided across the products are as follows:
• Automatic Dependant Surveillance – Broadcast (ADS-B) Out transmitted over 978 MHz Universal
Access Transceiver (UAT) link.
• Enhanced Visual Acquisition (EVAcq) using traffic information from ADS-B In received via a UAT
link.
• Flight Information Service – Broadcast (FIS-B) using received data via UAT link.
• Interfaces with RS-232 compatible transponders for the input of the Mode A squawk Code and mode
of operation from the aircraft’s existing Air Traffic Control Radar Beacon System (ATCRBS)
transponder or through a dedicated MODE A control panel interface.
The NGT-2000/25000 has an internal GPS receiver that provides own aircraft information (position,
velocity, track (or ground track), etc.) for ADS-B Out messages and traffic display.
This GPS is not intended as a position source to a navigation management unit that outputs deviation
commands keyed to a desired flight path.
When permitted the transmission of own ship identification can be inhibited using the Anonymous Mode
function provided by the CP-2500 control panel. This may only be accomplished when VFR Mode is active.
See Figure 1-1 for an overview of the unit’s system interface. The following paragraphs provide an
overview of each of these functions.
1.2.1 Enhanced Visual Acquisition Functional Overview
The Enhanced Visual Acquisition (EVAcq) function provides flight crews with a display of nearby traffic
relative to own aircraft (Cockpit Display of Traffic Information – Traffic Display) to assist with visually
acquiring traffic out the window and provide traffic situational awareness beyond visual range. Each
displayed traffic symbol conveys aircraft position, vertical trend and altitude information. Traffic on the
display (i.e. CDTI displays or some PED applications) can be selected by the flight crew to obtain
additional traffic information such as flight identification and ground speed.
The EVAcq function can display traffic on either an integrated traffic display (STIF or DTIF) or an
external traffic display (i.e. PED).
Data received via a UAT link (Ground stations- when in a coverage area) is the ADS-B, ADS-R
Rebroadcast, and TIS-B Traffic Information Service – Broadcast (traffic information used by EVAcq).
ADS-B (UAT) traffic can be received directly from another UAT equipped aircraft. TIS-B traffic and
ADS-R traffic can only be received when in the coverage area of an ADS-B ground station.
1.2.2 GPS Functional Overview
The GPS function utilizes signals from Global Positioning System (GPS) satellite constellation and
Satellite-Based Augmentation Systems (SBAS) such as the USA Wide Area Augmentation System
(WAAS), European EGNOS, Indian GAGAN and the Japanese MSAS. Currently it supports WAAS and
WAAS compatible SBAS systems.
The GPS signals are down converted to a low Intermediate Frequency, which is then processed by a micro
controller. This internal GPS function provides position, velocity, time and integrity (NIC, NAC etc)
information to the ADS-B functions and is ADS-B rule compliant with the position resource requirements
of AC20-165A.

1.2.3 FIS-B Functional Overview
The Flight Information Services - Broadcast (FIS-B) function provides pilots with a cockpit display of
certain aviation weather and aeronautical information for awareness of own aircraft location with respect
to reported weather, including hazardous meteorological conditions
NOTAMS/ METARS, etc) and NAS status (TFRs) indicators.
FIS-B is advisory information only and is intended to enhance pilot decision-making during strategic
flight planning. FIS-B augments traditional sources of this information such as ATC and Flight Service
Station (FSS). FIS-B information is provided over the ADS-B Services network on the 978 MHz UAT

1.2.4 ADS-B Out Functional Overview
The ADS-B Out function supports the transmission of Automatic Dependant Surveillance – Broadcast
(ADS-B) Out on a 978 MHz UAT link. The ADS-B Out data contains information about own aircraft
such as aircraft position, velocity, direction, etc. The ADS-B function receives aircraft data to output from
an internal GPS receiver.
Pressure altitude is received from existing altitude source, and control functions such as squawk codes,
Ident, and operational mode (e.g. Mode "A", Mode "C", etc.) is obtained from an approved control panel.
1.2.5 Multiple Source Inputs Operation
The NGT-2000/2500 has multiple Altitude source connections available. There is an option, through the
configuration module, of connecting RS-232 serial altitude source or Grey code altitude source, however
only one source can be connected at a time. The altitude source must be the same source used for the
mode "C" transponder if so equipped.
1.2.6 Discrete Inputs and Outputs
The MSS has discrete inputs and outputs that can be used in place of some functions that are not available
to equipment that is compatible with the MSS. See Figure 1-1.
• The Squat/Airspeed Monitor switch signals the On Ground status to the MSS via a squat switch, gear
switch, or external airspeed sensor input.
• The IDENT command activates SPI and transmits an ident pulse. An ident pulse highlights the
aircraft’s symbol on the ATC’s radar screen and is identified on the control panel when active.
• The MSS Transmit ON/OFF function is used to stop ADS-B out transmission. Setting this discrete
OFF turns the ADS-B Failure lamp ON.
• ADS-B Failure Lamp indicates that the MSS is unable to transmit due to the following:
1. If the indicator lamp is flashing at a slow rate, then the aircraft position information is invalid or
has failed. GPS may be acquiring signal in which case when it does the lamp will stop flashing.
Flashing will last only 2 minutes before the lamp stays ON.
2. If the indicator lamp is flashing at a fast rate then a Code mismatch (squawk code) has been
detected. The squawk code must be re-entered correctly (matching the transponder) using the
control panel.
3. If the lamp is ON, then the ADS-B has failed or the MSS Transmit ON/OFF switch is set OFF.
• No ADS-B Coverage lamp is used to indicate that the unit is not receiving an ADS-B ground station
signal.

1.2.7 Transponder Interface
• If the aircraft is equipped with a compatible transponder that has an RS-232 control panel output
(e.g. GTX-327), then the NGT-2000/2500 can receive mode control and the squawk code directly
from that transponder.
• If the aircraft is equipped with a non-compatible transponder, then the aircraft needs a CP-2500
Control Panel installed. With the CP-2500 the NGT-2000/2500 can wirelessly intercept the Mode A
squawk Code from the aircraft’s existing ATCRBS transponder and conduct a cross check between
the transponder broadcast value and the setting of the NGT-2000/2500 Mode A control panel setting
to ensure the consistency in selected Mode A squawk code selections.
If the code entered from the control panel does not match the Mode A response from the
transponder, then a Mode A mismatch failure message is set in the control panel and the aircraft call
sign is used in the UAT Message transmissions. Pilot action is required to assure that the codes set
into the transponder and the CP-2500 always match.
If a CP-2500 is not installed, then the ADS-B Failure indicator lamp will flash ON/OFF at a fast rate
indicating a Mode A mismatch failure. Pilot action is required to correct the condition.
• If the aircraft is not equipped with transponder, then the control panel may be configured to provide
squawk code data and mode control (i.e. standby, on, ALT modes).
1.3 EQUIPMENT DESCRIPTIONS
The NGT-2000 and NGT-2500 are equipped with a main sub-D connector (J2) and RF connectors (UAT
and GPS). A USB port (J1) is available to establish communication between the NGT-2000 and a
maintenance computer for installation and maintenance activities. Both units provide ADS-B In, ADS-B
Out, ADS-R, TIS-B Traffic, FIS-B weather, NOTAMS, and TFRs functionality. Figure 1-2 shows the
NGT-2000 system interface. Figure 1-3 shows the NGT-2500 system interface.
• The NGT-2000 and NGT-2500 both provide an RS-232 output that can be used to display UAT
ADS-B traffic as well as FIS-B weather information when an external WiFi accessory is connected
to transmit the received weather data to a commercial PED (i.e. Personal Electronic Device).
• The NGT-2500 outputs ARINC 429 to interface with an onboard cockpit display of traffic
information display (STIF or DTIF) for the display of own ship (DTIF only) and traffic information.
• The NGT-2500 can interface with a RS-422 data bus output that may be interfaced to a display to
provide weather or traffic information.
The UAT ADS-B In function supports the reception of ADS-B on a 978 MHz UAT link. The ADS-B In
data contains information about proximate aircraft such as aircraft position, velocity, direction, etc. and
also receives FIS-B data and ADS-R and TIS-B data from ground stations.
The ADS-B Out function is used to broadcast (without interrogation) periodic information about the
aircraft that includes aircraft identification, position, altitude, velocity and other aircraft status
information.

Revision A Prel-2014
NGT-2000/2500
DRAFT 3-2
Installation Manual
The FIS-B function provides pilots and flight crews with a cockpit display of certain aviation weather and
aeronautical information for awareness of own aircraft location with respect to reported weather,
including hazardous meteorological conditions and NAS status indicators. FIS-B is advisory information
only and is intended to enhance pilot decision-making during strategic flight planning. FIS-B augments
traditional sources of this information such as ATC, Flight Service Station (FSS), and Aircraft
Operational Communications Center. FIS-B information is provided over the ADS-B Services network on
the 978 MHz UAT link.
Table 1-2 describes the available built-in interfaces. Refer to Appendix A for detailed information on the
interface options. The traffic and weather display interfaces are only available to the NGT-2500 system
and requires a system product key to activate. See paragraph 1.3.1.

1.3.1 System Product Key
A product key is required if installing the NGT-2500 option. The product Key is a 10 digit code that is
used during installation and requires the NGT MAT to configure the unit. The product key is typically
shipped with the unit. If the product key is not included, contact L-3 Avionics Systems Customer Service
to obtain the code. Be sure to have the Mode-S ID (e.g. ICAO) available for the service representative.
1.3.2 Data Configuration Module
The NGT-2000/2500 interfaces to a Data Configuration Module (DCM), part number 9230-17003-01 for
the storage of configuration data. The DCM is permanently installed in the wire harness and interfaces to
NGT-2000/2500 via a 4 wire interface from the DCM.
The configuration settings are stored in the unit’s non-volatile memory and are entered via commands
sent over the maintenance interface to configure such items as:
• I/O port allocation (e.g. which external equipment is tied to RS-232 and ARINC 429 Tx lines, etc.).
• Aircraft Configuration Data (specific aircraft ID information, 24 bit unique ICAO address, make,
model, registration, etc).
• Mode A Control Panel type (RS-422).
• Optional equipment installation settings.
If the configuration data in the unit is not self-consistent (contains contradictory settings), the DCM is faulty
or the DCM has corrupted data, the unit will annunciate a failed state and not transmit ADS-B position
reports. A change in configuration data or replacement DCM will be needed to restore the unit to operation.
