INSTALLATION APPROVAL NOTE
Presently, no TSO standard exists for airborne FM transceivers. To make it easier for installation
agencies to provide their customers with an approved installation supported by an effective Airworthiness
Approval, Technisonic has secured Supplemental Type Certificate (STC) approval. The above referenced
DO-160G test data is also on file and available from Technisonic to support approval requirements in
airframes for which Technisonic does not possess an STC.
Approved aircraft types are listed in the attachments to the formal STC documents. These STCs are the
exclusive property of Technisonic and require the written authority of Technisonic for their use. To assist
Factory Authorized Technisonic Dealers in the certification process, we have placed copies of our
Canadian and US STCs on our website along with a letter of authorization for their use. These documents
may be downloaded and used as support for the technical submission to FAA or Transport Canada. Only
authorized factory dealers/installers are permitted to download and make use of these documents on
behalf of their customers (end users) in support of regulatory agency approval. Please refer to the
Technisonic website www.til.ca for the latest issue of available STCs and letter of authorization for use.

1.1 INTRODUCTION
This publication provides operating information on the TDFM-9200 airborne transceiver. The
exact configuration depends on which and how many RF modules are installed.
1.2 DESCRIPTION
The TDFM-9200 transceiver is an airborne multi-band radio capable of operation in conventional
analog and P25 digital FM systems, SmartNet/SmartZone trunking systems, and P25 9600
trunking systems. RF modules are available in single or dual bands that support VHF, UHF-LO,
UHF-HI, and 700-800 MHz bands. Up to 5 single or dual band modules can be supported.
These optional additional features include P25 9600 trunking Phase 1 and 2 that may be
combined with AES and/or DES-OFB encryption with OTAR in any of the available modules.
Bands 1 and 2 on the TDFM-9200 is not normally frequency agile. In order to have the ability to
change the frequencies at the front panel, the FPP (front panel programming) option must be
ordered for each band. FPP is only available on the VHF and UHF modules.
The TDFM-9200 has provisions for two of the above RF modules as well as two analog only
modules. These additional modules are fully frequency programmable from the associated front
panel. Analog only modules support CTCSS, DCS, wide, and narrow band operation where
applicable.
1.3 MODEL VARIATION
There are several variations of the Model TDFM-9200 Transceiver. Each variation offers different
features and performance based on the type of RF modules and options installed.
Rf Modules are mounded in trays of two with up to 3 trays supported.
The following is a breakdown of the TDFM-9200 model variations:
P/N 101263-D-90-TBB-TBB-TBB-P9XXXX

2.1 GENERAL
This section contains information and instructions for the correct installation of the TDFM-9200
Transceiver.
2.2 EQUIPMENT PACKING LOG
Unpack the equipment and check for any damage that may have occurred during transit. Save
the original shipping container for returns due to damage or warranty claims. Check that each
item on the packing slip has been shipped in the container.
2.3 INSTALLATION
The TDFM-9200 Transceiver is designed to be Dzus mounted and should be installed in
conjunction with an IN-9300 installation kit. See Figure 2.1 for an outline drawing of the unit with
dimensions to facilitate the installation.

2.7 INSTALLATION – WIRING INSTRUCTIONS
Figure 2-2(a, b, and c) show all required connections and recommended wire sizes for the TDFM-
9200 transceiver. The TDFM-9200 allows for either a single audio output ground or separate
grounds for each audio output. If a single point ground is required for a pre-existing installation,
the dongle supplied in the installation kit must be plugged into J5. If this is a new installation, it is
recommended to use the isolated ground returns to the audio panel for reduced cross talk
between bands and airframe noise. The audio panel must have isolated grounds for each audio
input (such as Technisonic’s A710, A711, A711L, and TDAP-711) to take advantage of this
feature. There are receive audio, mic audio, and Push To Talk (PTT) lines for each band as well
as two sets of lines combining all six bands. The TDFM-9200 can be wired such that band
selection can be made on the audio panel. Up to 6 positions need to be available on the audio
panel; otherwise, the TDFM-9200 can be wired into one or two positions of the audio panel where
band selection and audio monitoring is done on the TDFM-9200 front panel. An installation can
be wired in a combination of both methods since all inputs and outputs are always active.
2.8 MAIN GROUND – J1 PINS 1 AND 14
Both pins should be connected to power ground. These pins are internally connected to the
chassis.
2.9 MAIN POWER + 28VDC – J1 PINS 2 AND 15
Both pins should be connected to +28 volts DC +/- 15%.
2.10 MIC 1, 2, 3, 4, AND 5 – J1 PINS 3, 6, 9, J6 PIN 6, AND P1 PIN 15
The microphone input signals shall be connected using shielded wire with the shield connected to
ground (pin 1 or 14). It is recommended for best results to leave the other end of the shield
floating to prevent ground currents unless you are connecting to an audio panel with floating hi
and lo inputs (like the Technisonic A710, A711, A711L, or TDAP-711) in which case the shield
must be connected to the lo input. These are individual inputs for each band.
2.11 MIC COMBINED 1 AND 2 – J6 PINS 7 AND 13
The combined mic inputs should be wired and shielded as the individual mic inputs above. These
mic inputs that can be used for any band. Band selection is made at the TDFM-9200 front panel.
2.12 AUDIO 1, 2, 3, 4 – J1 PINS 4, 7, 10, J6 PIN 5, AND P1 PIN 6
These are individual audio outputs from each band. All outputs are 600 ohms impedance. The
output power is 65 mW maximum. Unused outputs do not have to be terminated and should be
left unconnected. These outputs are also found on J5 along with their respective grounds such
that a separate wire bundle can be run with only audio outputs, further reducing the possibility of
cross talk.
2.13 AUDIO COMBINED 1 AND 2 – J6 PINS 2 AND 10
These are combined audio outputs from all bands as selected from the front panel. The
specifications are the same as the individual outputs above.

2.14 PTT 1, 2, 3, 5, 6, AND 4 – J1 PINS 5, 8, 11, 21, 24, AND J6 PIN 3
There are individual PTT lines for each band. These lines should be floating when in receive and
grounded for transmit. The input has a pull up resistor to 5 volts. Connecting an audio panel that
wishes to see more may result in no receive audio. Connect a 1N4006 diode in series with the
cathode towards the audio panel in this case.
2.15 PTT COMBINED 1 AND 2 – J6 PINS 4 AND 12
These are combined PTT inputs to all bands as selected from the front panel. The specifications
are the same as the individual inputs above.
2.16 TX DATA AND RX DATA – J1 PINS 12 AND 13
These pins provide RS-232 serial communications for use with the RC-9000 remote control head
if installed. Consult the RC-9000 installation manual for details.
2.17 UP AND DOWN – J1 PINS 16 AND 17
These pins can be used to scroll up and down through the bands or channels for the band
currently selected depending on the band input below. The inputs normally floating are grounded
to activate. Two push buttons or a center off, SPDT, spring-loaded toggle switch are typically
used on these inputs.
2.18 CHANNEL/BAND – J1 PIN 18
The Channel / Band input determines the function of the up down inputs above. If left
unconnected, the inputs are for channel selection. If grounded, the input is for band selection.
2.19 PANEL BACKLIGHTING – J1 PIN 25
Connect to aircraft panel dimming bus. The transceiver is capable of supporting 28 VAC/DC or 5
VAC/DC backlighting circuits. Select 28 volts or 5 volts via the configuration menu (see Section
2.17 in the TDFM-9200 Operating Instructions manual). No damage will occur if the wrong setting
is made.
2.20 SPEAKER LO AND HI – J6 PINS 8 AND 9
Not normally connected in the aircraft. This output is 4 / 8 ohms at 1.1 watts max and has the
audio associated with Audio Combined 1. This output does not have to be terminated when not
used and should be left unconnected.
2.21 ANTENNA TUNER CONTROL LINES: P1 (PINS 1, 2, 3, 4, 5, 6, 10, AND 12)
These connections are to control an antenna tuner system such as the Foxtronics FLX-3050B.
Connect according to the manufacturer’s instructions. In the case of the FLX-3050B, the tune
indicator (which is normally connected to a light) can be connected to pin 10 so that the tuning
indication will show on the TDFM-9200 display. If a passive antenna is used, these lines shall
remain unconnected.
