1 GENERAL
This manual contains information about the physical, mechanical and
electrical characteristics and about installation and operation of the
Mode S Transponder TRT800H.
The conditions and tests required for TSO approval of this article
are minimum performance standards. Those installing this article
either on or within a specific type or class of aircraft must
determine that the aircraft installation conditions are within the TSO
standards which include any accepted integrated non-TSO function
standards. TSO articles and any accepted integrated non-TSO
function(s) must have separate approval for installation in an
aircraft. The article may be installed only according to 14 CFR part
43 or the applicable airworthiness requirements. This is an
incomplete system (antenna is required) intended to provide the
TSO functions specified in this Operation and Installation Manual,
section 5.1.

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 authorities. The received
Code
is assigned to the specific transponder/aircraft and must be
configured within the transponder. The 24-bit a
ddress is
stored in an external memory which allows t
he transponder
being exchanged without requiring any further configuration.
(for detailed information refer to sections 4.3.1 and 4.5.4).
•Class 1 Level 2es non-diversity Mode S transponder for ground
based interrogations at 1030 MHz and response at 1090 MHz

1.5 Deviations and Important Notes
The following deviations have been granted by the FAA:
The device is certified to FAA TSO-C112c in lieu of FAA
TSO-C112d.
Environmental Qualification Testing was performed
according to RTCA/DO-160D in lieu of RTCA/DO-160F.
The Software of this device was developed according to
RTCA DO-178B Design Assurance Level "D".
The ADS-B function of this device has not been evaluated
during the FAA TSO certification process other than to
ensure non-interference. Due to the SW assurance of DAL
"D", the ADS-B function cannot be used in the US National
Airspace.
Connecting a GPS source will not comply to FAA
certification requirements with regard to ADS-B.
This device contains an altitude measuring device that has
not been evaluated during the FAA TSO certification
process other than to ensure non-interference.
This feature must be evaluated for intended function
during FAA installation approval.
Compliance to RTCA DO-181D was verified by testing
against EUROCAE ED-73C. The two standards are
technically identical with regard to the TRT800H.

2.5 Flight-ID (FID)
The FID is an identifier required for 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.

Standard condition; transponder responds to mode A, C and S
interrogations.
•A – S „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.
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

2.00
If no 24-bit address (AA) was defined or entered as “000000“ the
transponder operates as a Mode A/C transponder, in that case the
following Modes are possible apart from Standby:
•A C – „Mode A+C“
Transponder replies only on Mode A and Mode-C interrogations.
•A – – 

„Mode A“
Transponder replies only on Mode A interrogations.
In STBY (Standby) mode, all transponder transmissio
ns
are disabled completely!
Therefore, the transponder is not
visible in this mode to air traffic control or the anti-
collision
systems onboard other aircrafts.
Never use the STBY mode in flight
unless you are requested
to do so by air traffic control. Alw
ays remember to put the
transponder in active mode prior to take off!
2.7 Squawk-Setting
The active Squawk is displayed in the upper line, while the standby
Squawk is presented at the lower line.
Setting 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)
2.8 VFR – Squawk
The transponder features a user-defined squawk code for VFR-flight
(factory setting: 7000):
•Activate VFR-Squawk:
Press VFR („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“

Squawk remains active!)
Example:
VFR VFR
•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 VFR until an „S“ is indicated (approx. 3 s); after
releasing the button „VFR“ is shown
2.9 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 ID a special position identification pulse (SPI) is
transmitted with every reply within 18 seconds, which causes an
accented marking on the Controller’s screen. The „Special Position
Identification“ has to be activated after the „Squawk Ident“ request of the
Controller.

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.

3.4 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 f.u.n.k.e.
AVIONICS GmbH.
•Select a position away from heat sources. Provide space 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 External Memory
Adapter TRT800EMxx as this is part of the certification and includes a
memory device in which the ICAO 24-bit Aircraft Address is stored.
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 an external Ground-Switch is connected to the transponder and
activated in the setup, the transponder can detect if the aircraft is
airborne or on the ground. This allows the transponder to automatically
activate the Ground mode whenever the aircraft is on ground.
In order to activate this feature, the input „FLY-GND“ must be connected
to an external switch which connects the input pin with „GND“ when the
gear is weighted, or remains open in the other case.
This feature must additionally be activated in the Setup. For details on
configuration please refer to section 4.5.4.
The (+UB)-wire has to protected by circuit breaker (2 Amp.)!
