3. Safety information
nThe 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.
nDo not connect the unit to AC sources.
nMake sure that the unit is connected to a DC source £33 V DC.
nIf no load is connected to pin 6 of P9, the unit should be protected from the
aircraft power supply by a dedicated 3 A circuit breaker.
nIf an external load is connected to pin 6 of P9, the circuit breaker should
be a 5A type.
nDo not connect the unit with reversed polarity to the DC source.
nDo not switch on the unit before the aircraft engines are started. Switch off
the unit before the engines are shut down.

nDo not operate the unit under ambient temperatures below -20 °C and abo-
ve +70 °C.
nVoltages > 42 V are possible within the transponder.
nThe programming of the address module AM6400-1 with the ICAO 24-bit
address of the aircraft must be carried out by an authorized installation
company or the manfacturer.

GENERAL DESCRIPTION
1. Application
The single block Mode S transponder BXP6401-X-(XX) is the airborne component of the
Air Traffic Control (ATC) Mode S Secondary Surveillance Radar system with added
ADS-B Transmitting Subsystem functionality. It acts as a part of the surveillance system
in two ways:
las a Mode S Transponder which provides responses to ground station interroga-
tions and allows air traffic control to locate, identify and track aircraft
las an ADS-B Broadcast-Only System which spontaneously broadcasts aircraft in-
formation
2. General description
A. The BXP6401-X-(XX) transponder is designed as a single block unit and is in-
tended for installation in the instrument panel of aircraft. The dimensions cor-
respond to the standard instrument size with a 58 mm (2¼ inch) diameter.
B. All control elements are located on the front panel of the unit. The two 25-pin
unit connectors for connection to the aircraft interwiring, the 5-pin subminiatu-
re connector for the Address Module AM6400-1-(XX) and the TNC antenna
socket are located at the rear side of the unit.
C. Serial interfaces RS-422 are available at the unit connectors.
D. The Mode S transponder provides the following features:
(1) In the selective mode (Mode S), the Ground Control can interrogate the
transponder individually using an ICAO-24-bit address, which is unique
to the particular aircraft.
(2) Support of the SI code (Surveillance Identifier)
(3) Register capability for elementary surveillance (ELS) and enhanced sur-
veillance (EHS)
(4) Extended squitters transmission
(5) Data link capability
(6) GPS receiver connection capability
(7) ADS-B Broadcast-Only System Class B0 i.e. broadcasts following data:
- Airborne Position Message
- Surface Position Message
- Airborne Velocity Message
- Extended Squitter Aircraft Status Message
NOTE:
Actual generation of each ADS-B message type and data within each
message depends on availability of navigation data and GPS engine ca-
pabilities.

INSTALLATION AND OPERATION BXP6401-X-(XX)

E. Inherent features:
(1) 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.
(2) 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 exter-
nal device (e.g. Becker Blind Encoder BE6400).
(3) A special identifier pulse (SPI) can be activated by pressing the IDT
button in Mode A/C and Mode S.
(4) Selftests (BITs). An Initiated Built-In Test (IBIT), a Continuous Built-
In Test (CBIT) and a Power-on Built-In Test (PBIT) are integrated in
the transponder.
