GENERAL DESCRIPTION
1. Application
The ATC 5401-1R-(01) remote controlled transponder forms, together with a corre-
sponding control unit, the airborne component of the Air Traffic Control Radar Bea-
con System ATCRBS. It functions in accordance with the secondary radar principle
and allows the respective ground stations to locate, identify and track aircraft.
2. General description
a. The ATC 5401-1R-(01) is a remote controlled transponder designed for
installation in the avionic compartment of the aircraft.
b. The 25-pin unit connector for connection to the aircraft interwiring, to an altitu-
de encoder and to the control unit as well as the TNC antenna socket are loca-
ted at the rear side of the remote controlled transponder.
c. The remote controlled transponder consist of the following electronic modules:
lprocessor board,
lreceiver board,
ltransmitter board,
lpower supply board,
linterwiring board.
d. The remote controlled transponder is controlled via a RS 422 interface. The
control units listed below are recommended.
CU 5401-1-(xxx), manufacturer: Becker Flugfunkwerk GmbH
RMU 5000-1-xxxx, manufacturer: Becker Flugfunkwerk GmbH
Other control units can be used if the serial data interface of the unit is in ac-
cordance to the ”Serial data interface requirement for the ATC 4401-XX”, do-
cument ID 9620.SICD.000. This document is available on request
e. The remote controlled transponder performs the following functions:
(A) Mode A - in this mode, the code set on the remote controlled trans-
ponder is sent as a reply to interrogation from a ground station. The
mode is selected by software command via the RS 422 interface.
(B) Mode C - in this mode, the encoded flight level is sent in addition to
the possibilities of mode A, if an encoding altimeter has been connected
to the remote controlled transponder. The mode is selected by software
command via the RS 422 interface.

(C) Indication of flight level (altitude/100) on the corresponding Con
trol Unit (Becker CU 5401-1-(xxx) or RMU 5000-1-xxxx) if an encoding
altimeter is connected to the remote controlled transponder.
(D) Ident function – If the ”ident” command is received from the control unit
on the RS 422 interface, the special pulse (SPI) is transmitted together
with the code and altitude data. The SPI permits immediate identificati-
on of the aircraft on the controller’s radar screen by means of additional
marking on the object display.
(E) BITE – Several self test routines are implemented and active automati-
cally or on request via RS 422 interface.
(F) PBIT (Power on BIT) – Those test routines are running if the power is
switched on. The result is sent to the remote control unit via the RS 422
interface for indication of possibly detected failures.
(G) CBIT (Continuous BIT) – This test routine is active in background. If any
failure is detected, the unit send a failure message to the remote control
unit via the RS 422 interface.
(H) IBIT (Initiated BIT) – This test routine will be started on request by a
command received on the RS422 interface. For indication purpose, the
test result is sent to the remote control unit on the RS422 interface
f. Discrete input function: The remote controlled transponder provides the
following discrete input functions:
Altitude encoder connection:
Inputs to connect an external altitude encoder. Inputs are A1, A2, A3; B1, B2,
B3; C1, C2, C3; encoder common.
Ident Ext.
Input to connect an external Ident push button.
g. Discrete output functions: The remote controlled transponder provides
two different discrete output functions:
DME-Suppression:
Output for connection to a DME. If the remote controlled transponder is in
transmit mode, this output will prohibit a DME transmission at the same time.
Reply out:
Output line for connection of an external indicator lamp or LED.
