6. Programming of the Address Module
The 24-bit ICAO address once allocated by the local authority is stored for the as-
signed transponder in the Address Module AM6400-1-(01).
The address module programmer kits AMP6400-1 (parallel interface) and
AMP6400-2 (USB interface) are tools for reading and storing fixed aircraft data into
the Address Module. This tools are for service and maintenance only.
The CD-ROM, which is part of the address module programmer kit, includes a des-
cription of the programming procedure. Insert the CD-ROM into a PC and follow the
instructions. If autostart is disabled on your PC, you have to start “setup.exe” manu-
ally.
7. Avionics data transfer
A. The BXP 6401-X-(XX) is a “data link transponder” according to RTCA
DO-181C, respectively a “level 2es” transponder according to EUROCAE
ED-73B.
This stands for the capability to transfer data from the ground to a
connected ADLP or a similar device and vice versa.
B. The transponder transmits information as reply on a Ground Initiated Comm-B
(GICB) request or by means of the extended squitter function. In both cases
the valid information must be available in the GICB registers in the transpon-
der.
C. The transponder also transmits information by means of the Air Initiated
Comm-B (AICB) function. In this case the information must be available in a
special register in the transponder. The transponder announces the message
and transmits it after authorisation from the ground station.
D. In the other direction, the transponder is able to receive information within a
Comm-A format from the ground station, which is then buffered and transferred
to the connected device.
E. In the BXP6401-X-(XX) a “storage design” is implemented for uplink- as well
as for downlink messages. This means that all information that might be trans-
ferred from the transponder is buffered inside the transponder first.
F. The buffers can be accessed from an ADLP or a similar device via the interfa-
ce on the rear connector J8. The interface is marked with “TISRX” and “TISTX”
in the aircraft wiring diagram (see Fig. 2-3
and Fig. 2-4).
G. The related protocol is specified in the attachment document “Data Transfer
Interface Protocol BXP 640X-XX-(XX)”. This manual is available at the Becker
Product Support under the Article-No. 0590.258-071.
