General Description
Purpose of Equipment
DV15104.3 Issue 06 September 2018 BXT6500 Series 15
1.2 Purpose of Equipment
The BXT65XX transponder is designed as a remote-controlled single block device and is intended 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 Category Message.
o Aircraft Operational Status Message.
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.
Actual generation of each ADS-B message type and data within each message
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 configuration is stored in a non-volatile memory. There are two possibilities where to
store configuration data:
• Use the internal memory.
• Use the external memory module EM6100.
The selection of equipment configuration source is done by hardware configuration (see "Data Source
Configuration", page 56).
Diversity
Antenna diversity reduce the potential for antenna "shading" and helps to prevent target drop out in
each situation.
BXT65XX-(000) is capable to operate with two antennas (top and bottom), required 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).
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.
o The altitude information must be delivered from an external device.
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.
• 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.

ADS-B (Automatic Dependent Surveillance-Broadcast)
ADS-B is a GPS based technology to define and provide aircraft relevant data. To support ADS-B Out,
the aircraft needs a certified GPS receiver as the position source, and this device to send the ADS-B
data. This data can be received by other air- and ground stations.
The Automatic Dependent Surveillance-Broadcast Out (ADS-B Out) function provides position,
velocity and status data on the transponder for broadcasting as extended squitter (ES). When data is
available, it is transmitted at specific periods and enable other participants to determine current
position, velocity and status of the aircraft without interrogation.
BXT65 series is an ADS-B class B1 or B1S (aircraft broadcast only) Mode S transponder capable for
automatically sending out ADS-B data like:
• (BDS 0,5) Airborne Position Message.
o Special Position Identification (SPI).
o Emergency Indicator.
o Barometric Altitude.
o Quality Indicator (NIC).
o Latitude (Airborne Position).
o Longitude (Airborne Position).
• (BDS 0,6) Surface Position Message.
o Quality Indicator (NIC).
o Latitude (Surface Position).

Summary of Operational Description
• The BXT65 series is continuously monitoring incoming RF signals at frequency of
1030 MHz for radar interrogations.
• When an interrogation is detected and decoded, the transponder processes 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.

Antenna Installation
For antenna installation, refer always to the manufacturer´s maintenance documentation for the
aircraft. Carry out the antenna installation in accordance with AC 43.12-2A Chapter 3.
Penetration of the pressurised cabin on a pressurised aircraft requires additional
data, which are not contained in this installation manual.
Radiation risk:
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.
The picture shows a typical location for top and bottom antenna installation for Diversity Mode S
transponder. For single antenna device install only the bottom antenna.
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 inspection of the area between antenna
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.

2.7.5.1 External Memory Module
External memory interface signals are available at P1 connector and EM connector.
If the External Memory module EM6100 is used as configuration data source the mechanical
installation is as per description:
• Backshell installation
(fix the EM6100 module to the pre-assembled connector at the backshell. Please note,
use a cable connection as short as practical but not longer than 150 mm).
Do not install two External Memory modules at same device. The External
Memory module must always be installed when it is defined as configuration data
source (see "Data Source Configuration", page 56.
In dual device installations with External Memory module as a configuration data
source, each device needs its own External Memory module.
In case of dual device installation, it is the responsibility of the installer to provide
correlated data to each device.
Please make sure that configuration data of both devices match to the aircraft and
installation. Aircraft properties include:
• Mode S address.
• Maximum airspeed.
• Aircraft registration.
• Aircraft category.
• Length and width code.

Configuration Data
DV15104.3 Issue 06 September 2018 BXT6500 Series 63
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 possibilities where to store or load configuration data (see "Data Source Configuration"
page 56):
• Usage of the internal memory or
• Usage of an external memory module.
• We recommend the usage of the External Memory module EM6100 as data
source.
Configuration of BXT65XX with EM 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.
Configuration 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
removing it.
For detailed information please contact Becker Avionics.
For relevant department and addresses, please see contact info page 2.
For wiring example - service connection - see also "Figure 27: Software Update – Aircraft Installation" page 64.

Post Installation Check
70 BXT6500 Series DV15104.3 Issue 06 September 2018
2.11 Post Installation Check
Once the device is installed completely a test procedure shall be started to verify system functionality.
Ensure compliance with authority required procedures. The following text provides guidance for such
tests.
Mechanical Installation and Wiring Check
• Verify all cables are securely fixed and shields connected properly to signal ground.
• Check the movement of aircraft controls to verify there is no interference.
• Verify all screws are tight, check if all connections are mechanically secured.
Power Supply
• Check the power supply lines and confirm correct polarity. Don´t apply reverse voltage!
• Confirm that the aircraft power supply is within the specified limits, with and without a
running engine.
• Check LEDs (see "Meaning of Status LEDs" page 38).
Antenna Check
• Applying portable reflectometer or network analyzer measure the voltage standing wave
ratio (VSWR) at the transponder end of antenna aircraft installation.
• The measured VSWR at frequencies 1030 MHz and 1090 MHz shall not exceed 1.5:1.

DV15104.3 Issue 06 September 2018 BXT6500 Series 71
Interference Check
• Check the device while engine is running and powered on all other avionics/ electrical
systems on the aircraft, to verify that no significant interference exists.
• Check also that the device does not cause significant interference with other systems.
The installer´s standard test procedure may be used for the interference check and the following table
can be taken as a reference. Depending on the individual avionic systems installed in the aircraft, it
might be necessary to extend the following checklist accordingly.

For the remaining avionic equipment repeat all interference checks during a flight and include all
equipment not previously checked out on ground.
Mode S Ground Test
After successful completion of the previously described post installation checks perform a Mode S
ground test. (Refer to FAR 43 Appendix F or EASA CS-ACNS). The part 145 company approved test
protocol shall finally be used.
An experienced test setup configuration shall also be arranged, otherwise refer to the user instruction
of your specific test equipment.

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 transmissions,
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.
