1.4 Features
In order to operate the Mode-S transponder it is necessary
to request an ICAO 24-Bit Aircraft Address at the
responsible national aviation authoritys. The received Code
is assigned to the specific transponder/aircraft and must be
configured within the transponder. The 24bit Address is
stored in an external memory which allows the transponder
being exchanged without requiring any further configuration.
(for detailed information refer to sections 4.1.2 and 4.2.1).

2.4 Flight-ID (FID)
The FID is an identifier required by Mode-S Operation. During future
application of flight plans a FID could be assigned on a per flight basis. If
no FID is assigned (today’s normal case) the registration marking of the
aircraft should be used as FID. The FID should not contain dashes or
blanks. The FID must not be confused with the 24-bit Aircraft Address.
2.4.1 Display of Flight-ID
Press (repeatedly) until „STBY“ appears
Press and hold ; while a counter is shown beside the active squawk,
release at values between 1 and 4
Display:
The lower line contains the 24bit address (AA) and the aircraft category
(AC), marked by a line above the numbers as well as the Flight-ID (FID)
without any line above the numbers (“^”=cursor):
digits 1 to 6: ICAO 24-bit Aircraft Address (AA, HEX-format)
digits 7 to 8: Aircraft Category (AC)
digit 9 to 16: Flight Identification (FID)
This screen will appear for 5s and will be left automatically afterwards.
2.4.2 Configure Flight-ID
Press (repeatedly) until „STBY“ appears
Press and hold ; while a counter is shown beside the active squawk,
release at values between 5 and 19
Enter Flight-Id with cursor button and rotary knob
Press to save and return to STBY
Please refer to section 4.2.1 for configuration of the 24-bit Address (AA)
and Aircraft Category (AC).
Enter FID left-aligned, without any blanks or dashes(!), e.g.
12345621DEFAV for the marking D-EFAV. The last
remaining digits shall be filled with blanks

2.5 Transponder Mode selection
Press (repeatedly) to select from following Modes:
•STBY Æ„Standby“
Transponder only responds to directly addressed Mode S
interrogations, squitter remains active.
If a ground switch is connected, actuation of this switch will cause
the transponder switch to standby mode.
•ACS Æ„Mode A+C+S“
Standard condition; transponder responds to mode A, C and S
interrogations.
•A-S Æ„Mode A+S, no C“
Altitude is not transmitted (neither on C nor on S requests). All
other Mode-S data as well as Mode-A replies are transmitted.
If no 24-bit address (AA) was defined or entered as “000000“ the
transponder workes as Mode A-C transponder, in that case the
following Modes are possible apart from Standby:
•AC- Æ„Mode A+C“
Transponder replies only on Mode A and Mode-C interrogations.
•A-- Æ„Mode A“
Transponder replies only on Mode A interrogations.
2.6 Squawk-Setting
The active Squawk is displayed in the upper line, while the standby
Squawk is presented at the lower line.
Settgin the Standby Squawk:
•Press to set the cursor („^“), turn rotary knob to set numbers of
the standby Squawk.
•Press to activate the Standby Squawk , this moves the current
active Squawk into Standby

2.7 VFR – Squawk
The transponder features a user-defined squawk code for VFR-flight
(factory setting: 7000):
•Activate VFR-Squawk: Press („VFR“ is indicated), now the
active Squawk is moved into Standby but not visible because the
indication of the Standby Squawk is overlapped by „VFR“
•Display Standby Squawk::
Press or or use the rotary knob (the VFR-Squawk
remains active!)
Example:
•Now the Standby Squawk can be adjusted by using the rotary knob
and activated with .
•In order to store the current active Squawk as new VFR-Squawk
(replacing the factory setting 7000):
Press and hold until an „S“ is indicated (approx. 3 s); after
relasing the button „VFR“ is shown
2.8 ID – Special Position Identification (SPI): “Squawk
Ident”
Press ID to activate transmission of the special position identification
pulse with every reply within 18 seconds; “IDT” appears on the display
By pressing a special position identification pulse (SPI) is transmitted
with every reply within 18 seconds, which causes an accented marking
on the Controler’s screen. The „Special Position Identification“ has to be
activated after the „Squawk Ident“ request of the Controler.
2.9 Error-Codes
Please refer to 2.3 Display-Indications for possible displayed errors.

3 INSTALLATION
3.1 Notes
The following suggestions should be considered before installing.
The assigned installation company will supply wiring. For diagrams refer
to 3.7 Wiring.
Transponder, External Memory, all cables and antennas shall be
installed according to „FAA AC-143.13-2A Acceptable Methods,
Techniques and Practices – Aircraft Alterations“ and the appropriate
manufacturer’s instructions.
3.2 Telecommunication data
Depending on your national telecommunications legislation, the following
data may be required when applying for the aircraft radio station license:
Manufacturer: Funkwerk Avionics GmbH

3.4 Unpacking and Inspecting of the Equipment
Carefully unpack the equipment and inspect for transport damages. If a
damage claim has to be filed, save the shipping container and all
packing materials as evidence to your claim.
3.5 Mounting
•In cooperation with a maintenance shop, location and kind of the
installation are specified. The maintenance shop can supply all
cables. Suitable sets of cables are available from Funkwerk
Avionics GmbH.
•Select a position away from heat sources. Care for adequate
convection cooling.
•Leave sufficient space for the installation of cables and connectors.
•Avoid sharp bends and wiring close to control cables.
•Leave sufficient lead length for inspection or repair of the wiring of
the connector (containing the memory), so that when the mounting
hardware for the rear connectors is removed, the assembly may be
pulled forward several inches.
•Bend the harness at the rear connectors to inhibit water droplets
(formed due to condensation) from collecting in the connector.
•For mounting details/drawing refer to chapter 3.12.2 Mounting
Advices.
For storage or reshipment the original packaging should be
used.

3.6 Equipment Connections
3.6.1 Electrical Connections
One 15 pin D-SUB miniature connector includes all electrical
connections, except for the antenna. Use only an AC Address Adaptor
TRT800EM or TRT800EMSS as they are part of the certification and
include a memory with the stored ICAO 24bit Aircraft Address.
3.6.1.1 Mutual Suppression
Other equipment on board (e. g. DME) may transmit in the same
frequency band as the transponder.
If such a device is installed a suppression wiring shall be installed in
order to protect the receiving parts of the different devices from in-band
transmissions.
Mutual suppression is a synchronous pulse that is sent to the other
equipment to suppress transmission of a competing transmitter for the
duration of the pulse train transmission. The transponder transmission
may be suppressed by an external source and vice versa.
To activate mutual suppression connect the SUPP_I/O signal to the
according signals of the other equipment
3.6.1.2 Ground Switch
If a Ground-Switch is connected (and activated in the Setup), the
transponder is enabled to distinguish between On-Ground and In-Flight.
Condition. In On-Ground Condition the transponder automatically enters
the Standby mode.
In order to activate this function the signal „FLY-GND“ must be
connected to a switch, which combines the signal with „GND“ in case the
gear is weighted, or remains open in the other case.
This option must additionally be activated in the Setup. For details on
configuration please refer to section 4.2.1.
The (+UB)-wire has to protected by circuit breaker (2 Amp.)!

unconnected.
•Illumination can be varied using an input voltage (dimmer or
switch) from 0 V .. +UB connected to „LIGHT“.
(0V for off, +UB for full brightness, inbetween linear)
3.6.2 Static Air Port
Install a silicon soft tube fitting the 5 mm static air port at the backside of
the transponder and secure plumbing with appropriate clamps.
