The remote controlled Mode S transponder BXP6402-XR-(XX) forms together with a control unit
(e.g. CU6401) an airborne component of the Air Traffic Control (ATC). It works as a Mode S
Secondary Surveillance Radar system with added ADS-B Transmitting Subsystem functionality.

In the selective m ode (Mode S), the Ground Co ntrol c an inter rogate the transp onder ind ividually using
an ICAO 24-bit address, which is unique to the particular aircraft.

BXP6402-XR-(XX) works as a part of the surveillance system in two ways:

• As Mode S transponder which provides responses to ground station interrogations and
allows air traffic control (ATC) to locate, identify and track aircraft.

• As ADS-B Broadcast-Only System which continuously transmits aircraft information.

Introduction

1.1. Introduction

This manual describes the installation and operation of the Mode S transponder BXP6 402-XR-(XX).
The ID label on your device shows the part number for identification purposes (see "Type Plate",
page 25).

Before starting operation of the unit(s) please read this manual carefully, with particular attention to the
description referring to your device(s). This manual also contains several optional elements of the
system (Blin d encoder for example) that m ay not be contained in your delivery package and in t hat
case are not applicable.

For further descriptions we are using the term BXP6402 instead of writing the complete model
number.

The manuals “Maintenance and Repair” (M&R) and “Installation and Operation (I&O) contain the
following sections:

General Description

Purpose of Equipment

1.2. Purpose of Equipment

The BXP6402 transponder is a remote controlled unit designed for installation in the avionic
compartment of aircraft.

• All connectors for connection to the aircraft interwiring, adddress module, antenna and
altitude encoder are located at the rear side of the unit.

• Serial interfaces RS422 are available at the unit connectors.

o Control via: Control unit CU6401.
o Control via: "External" unit (e.g. ADLP).

• Easy mounting; to meet the conditions for certification use the mounting method with

Mode S features:

mounting kit MK4401.

• Individual interrogation of the transponder ICAO 24-bit address.

• Support of the SI code (Surveillance Identifier).

• Register capability for elementary surveillance (ELS) and enhanced surveillance (EHS).

• Extended squitters transmission.

• Data link capability.

• GPS receiver connection capability.

• ADS-B Broadcast-Only System Class B0 e.g. broadcasts following data:

o Airborne Position Message
o Surface Position Message
o Airborne Velocity Message
o Extended Squitter Aircraft Status Message

Inherent features:

• Mode A - in this mode, the 4096 character code set on the control head is sent as a reply
to interrogation from a ground station.

• Mode C - in this mode, the encoded altitude is sent in addition to the mode A reply.
The altitude information must be delivered from an external device (e.g. Becker Blind
Encoder BE6400).

• A special identifier pulse (SPI) can be activated by pressing the IDT button in Mode A/C
and Mode S.

• Selftests (BITs). The Initiated Built-In Test (IBIT), the Continuous Built-In Test (CBIT) and
the Power-on Built-In Test (PBIT) are integrated in the transponder.

The BXP6402 is to be used inside the declared limits.

1.4. Safety-Conscious Utilization

For safe operation of the product the following notes have to be observed:

• The installation of the Mode S transponder into an aircraft may be carried
out only by an authorized installation company. The country regulations
always have to be observed.

• Use the product only within the specified conditions, see "Technical Data"
page 16.

Power supply:

• Do not connect the unit to AC sources.

• Make sure that the unit is connected to the mandatory DC source, see

"Technical Data" page 16.

• Do not connect the unit with reversed polarity to the DC source.

Circuit breaker:

• If no load is connected to connector P9, pin 6, the unit should be protected
from the aircraft power supply by a dedicated 3 A circuit breaker.

• If an external load is connected to connector P9, pin 6, the circuit breaker
should be a 5 A type.

Address module:

• The programming of the address module AM6400-1 with the ICAO 24-bit
address of the aircraft must be carried out at an installation company or in
the manufacturer factory. A programming kit is available see "Order Code"
page 21.
