Purpose of Equipment
Actual generation of each ADS-B message type and data within each message
1.2 Purpose of Equipment
The BXT65XX transponder is designed as a r emote-controlle d single blo ck device and is intende d for
installation in aircraft avionics bay.
BXT65XX is a transponder which provides to other stations Mode A/C/S messages as well ADS-B
Extended Squitter functionality (ES).
BXT65XX is a remote-controlled device, which does not include a control panel. It can receive
commands and provides data through a set of standard interfaces.
Features:
• Control Interface ARINC 429.
• Mode A - in this mode, the 4096 character code is sent as a reply to interrogation from a
ground station.
• Mode C - in this mode, the encoded altitude is sent with 100 ft resolution.
• Mode S - interrogations are selective and Mode S transponders will respond to an
interrogation from ground stations or another aircraft with a reply containing its ICAO 24bit
address.
• ADS-B Broadcast-Only System, transmit:
o Airborne Position Message.
o Surface Position Message.
o Airborne Velocity Message.
o Aircraft Identification and C ateg ory Message.
o Aircraft Operational Status Mes sage.
o Extended Squitter Aircraft Status Message.
• ADS-B receiver subset captures Extended Squitter messages from aircraft and ground
vehicles (ADS-B IN functionality not certified).
• Single Antenna Operation (bottom antenna).
• Diversity - operation with two antennas (top and bottom)
o This is required for TCAS ǁ equipped aircraft.
o Additionally, in Europe for installation in aircraft with gross mass in excess of 5700 kg
or a maximum cruising true airspeed in excess of 250 kt (463 km/h).
• Support of the SI code (Surveillance Identifier).
• Elementary surveillance (ELS) and enhanced surveillance (EHS).
• Data link capability.
• GPS receiver connection capability.
• Selftests (BITs) are integrated in the transponder.
depends on availability of navigation data and GPS capabilities.
Actual provision of ELS and EHS data depends of availability of these data from
external equipment and configuration.

Fixed and Non-Volatile Data
The BXT65XX conf iguration is stored in a non-vol atile memory. There are two possibilities where to
store configuration data:
• Use the internal memory.
• Use the external memory module EM6100.
The selection of eq uipm ent conf iguratio n so urce is done by har dwar e conf igura tion (s ee " Data Sourc e
Configuration", page 56).
Diversity
Antenna diversity reduc e the potential for antenn a "shading" and helps to prevent target drop out in
each situation.
BXT65XX-(000) is capab le to operate with two antennas (top and bottom), required f or installation in
aircraft with gross mass in excess of 5700 k g or a m aximum cruising true airspee d in ex c ess of 250 kt
(463 km/h).
Mode C, Mode S
Mode C - in this mode, the encoded altitude is sent in addition to the mode A reply.
• Mode C - in this mode, the encoded altitude is sent with 100 ft resolution.
o Data range for 100 ft resolution: -1000…126 750 ft.
BXT65 series as Mode S transponder is an airborne part of Mode S Secondary Surveillance Radar
system which detects ground interrogations arriving at 1030 MHz signal frequency, processes them
and generates responses at 1090 MHz signal frequency.
o The altitude information must be delivered from an external device.
• Mode S - interrogations are selective and Mode S transponders will respond to an
interrogation from ground stations or another aircraft with a reply containing its
ICAO 24 bit address.
o Data range for 25 ft resolution: -1000…50 187 ft.
o Data range for 100 ft resolution: -1000…126 750 ft.
o The altitude information must be delivered from an external device.

• When an interrogation is detected and dec od ed, the tr a nspond er proces s es it and
generates a reply which is transmitted at radio frequency of 1090 MHz.
• Transponder replies allow an ATC ground station to locate, identify and track an aircraft.
• With use of interrogations and replies it is also possible to send data to and from an
aircraft.
• The device provides transponder functionality for Mode A/C and Mode S operation.
• The BXT65 series periodically transmits squitter, which are transmitted independent on
interrogations from ground stations.
Two types of squitter are generated:
• An acquisition squitter carries 56-bit data allowing acquisition of the aircraft is transmitted
approximately once per second.
• Extended squitter carries 112 bits of data and are used by ADS-B transmitter function.

transponder. For single antenna device install only the bottom antenna.
A safe distance to the installed antenna must be ensured by corresponding
installation measures around human body damage (e.g. at the eyes) and/or avoid
the inflammation of combustible materials by radiated energy.
Figure 5: Antenna Installation (diversity)
Transponder antennas should be installed as far away as practical from:
• Other antennas.
• Shadowing produced by other installations on the surface of the aircraft body.
• Exhaust path of the engine(s).
• Landing gear doors or other openings.
• Check the skin panels for sufficient bonding before the antenna installation.
• Separate the transponder antennas from DME and TCAS as much as possible
(approx. 1.8 m or 6 feet as guideline).
• Generally, transponder antennas should not be installed closer than 3 ft to the
transponder. Otherwise RF interference may occur.
• Mount the main antenna on the bottom of the aircraft fuselage in a vertical position, same
as the top antenna. Horizontal separation of both antennas should not exceed 7.6 meters
(25 ft).
• Follow the manufacturer´s installation instruction for the antenna to ensure achieving
maximum performance of the BXT65 series.
• If existing antennas on the aircraft will be used an inspec tion of the area bet ween ante nna
and the aircraft skin is highly recommended to avoid negative effects of possible corrosion
in this area.
• On composite aircraft, add sufficient ground plane material.

2.7.11.1 Burst Mode - Sticky Mode Operation
The device scans all control inputs for presence of control words. Once a command word is received
from an input, th e device "s ticks" to this input - accepts command f rom this input and ignores other
inputs for as long as the selected input provides commands periodically. Once commands stop to
arrive, the device restarts the input scanning process.
Relevant configuration settings:
2.7.11.2 Burst Mode - Concentrator Mode Operation
The device processes commands from each controller with a "last command wins" principle. This

2.8 Configuration Data
The BXT65 series must be configured with the characteristic aircraft data.
The BXT65 series configuration is stored in a non-volatile memory.
There are two possibilit ies where to store or load configurat ion data (see "D ata Source Conf iguration "
page 56):
• Usage of the internal memory or
• Usage of an external memory module.
The configuration parameters of the BXT65XX with EM module can be set directly by PC via
"EMP Kit" and the corresponding software program.
Detailed information is available in "EMP Extended Memory Programmer User Manual", please see "Order Code", "Available
Documentation" page 32.
• We recommend the usage of the External Memory module EM6100 as data
source.
Configur ation of BXT65XX with EM module
Configur ation of BXT65XX with internal memory
• The usage of the internal memory as configuration data storage can only be
approved when customers have and maintain an own configuration data base.
o It is a condition to store the current configuration data in the
configuration data base.
• If the internal memory is used it is necessary to install a service connector at a
suitable place inside the aircraft to be able to configure the device without

3.2 Start-up
Built In Tests (BIT)
BXT65 series has advanced Built-In-Test. It monitors most of internal circuits against failures. In
addition BIT monitors some external (installation) conditions to increase reliability. There are three
types of BIT implemented:
• PBIT (performed after Power ON the device).
The test routine PBIT checks:
o System integrity,
o Software integrity,
• IBIT (initiated by special command via ARINC protocol).
The test routine IBIT checks:
o Transmitter operation
• CBIT (which continuously check operation).
The test routine CBIT checks:
o Reply transmissions,
o Squitter transmiss ions,
o Transponder receiver operation,
o Interfaces operation,
o System integrity,
o Equipment temperature,
o Internal voltages.
Extended Temperature
The BXT6553 contains an internal heater which heats the device(s) at low temperatures.
• In case the internal temperature is below -40 °C during power-on of the device(s), the
transponder remains switched off.
• As soon as the heater has increased the temperature above -40 °C the transponder is
switched on.
o During this period the transponders is inoperable and will supply an XPDR Fail signal.
• This period takes at maximum 20 minutes at nominal supply voltage.
