1. INTRODUCTION
1.1 SCOPE
This manual provides installation and operation instructions for the Terra by Trimble TN
200D Navigational Receiver manufactured by Trimble of Austin, Texas.
1.2 DESCRIPTION
The Terra by Trimble TN 200D is a small, lightweight, all solid state navigational receiver
available with and without a glideslope receiver. The digital frequency synthesizer provides
200 channels with 50 KHz spacing from 108.00 to 117.95 MHz. The receiver provides VOR/
LOC information to navigational converters while the glideslope receiver completes the ILS
capability and supplies remote DME channeling.
The TN 200D features microprocessor controlled frequency synthesizers that employ phase
lock loop circuits to generate local oscillator frequencies. Other features include a user
programmable 10 location memory, active and standby frequencies displayed on a planar gas
discharge display, an Ident-voice switch to filter station Ident from receiver audio and a
rotary frequency selector.
SECTION I
The receiver can be mounted in three different configurations: in a single tray, in a double
tray or in a 3" ATI hole using the 3" adapter. With tray mounted units, all power and control
connections are made to a 15 pin “D” type connector installed in the rear of the mounting
tray. A standard BNC male chassis connector is supplied on the tray for antenna
connections. For the 3" option a locking, hooded, 15 pin “D” type connector and standard
BNC male connector are used respectively for power/control and antenna interfacing. The
TN 200D is secured by means of a positive locking cam, accessible through the front panel.
The 3" option is mounted with a minimum of 3 screws through the instrument panel.
Weighing only 1.14 lb. (.517 kg) without the glideslope option and 1.43 lb (.649 kg) with
glideslope, the TN 200D measures 11.450" long, 3.125" wide and 1.625" high (29.083 cm x
7.938 cm x 4.128 cm). Panel cutout is a mere 3.03" x 1.54" (7.70 cm x 3.91 cm) and the
overall length of the unit is only 12.80" (32.50 cm) including the mounting tray.
Pulling only 300 mA of current without the glideslope receiver and 600 mA with the
glideslope option, the TN 200D operates at 13.75 VDC. Operation at 27.5 VDC is possible
by utilizing an optional Terra by Trimble MLC 28-5 power converter P/N 0900-3219-12.
The TN 200D is designed to work with standard aircraft auxiliary audio amp systems as per
wiring diagram, or a high impedance headset.

2. INSTALLATION
2.1 GENERAL
This section contains all necessary installation instructions and checkout procedures for the
Terra by Trimble TN 200D Navigational Receiver.
2.2 PREPARATION FOR USE
Every precaution has been taken to protect the TN 200D during shipment. Upon receipt of
the equipment, perform the following inspections:
1. Remove the unit from the shipping container and visually inspect for damage.
2. Check controls and switches to determine if they may have been damaged.
3. Make sure that all hardware and connectors listed in Section I, under “Equipment
Supplied”, are present.
If the unit is damaged, a claim must be filed with the carrier. The carrier assumes title of the
unit when it accepts it for shipment. Do
It is suggested that the package be retained for inspection by the carrier in the case of
damage or for future use should it be necessary to ship the unit for service or to transfer it to
another location.
SECTION II
not return it to Trimble or its representatives.
2.3 GENERAL INSTALLATION INSTRUCTIONS FOR AVIONICS
The following paragraphs contain pertinent hints, advice, and guidance intended for use by
installers of avionics equipment. These have been drafted to address common problems
encountered during the installation process. Specific questions may be addressed to Trimble
for technical assistance by calling 1-800-487-4662 and requesting Technical Assistance.
2.3.1 COAXIAL CABLES AND CONNECTORS
Improper installation of coaxial cables and connectors create many of the problems
encountered during avionics installations. Refer to Figure3-1 for guidance of typical
BNC connector assembly. Refer to Figure 3-2 for instructions about connecting coax
cable to the BNC connector(s) mounted at the rear of Terra by Trimble mounting
trays. Problems to avoid include twisted, chafed, or pinched cables, sharp bends in
cables, open or shorted center conductors or shield braid, and improper grounding of
shields. Also, proper termination of antenna coaxial cables at the antenna should be
carefully checked. After installing connectors, pull firmly to ensure good mechanical
bonding (particularly if you use crimp-on connectors) and use your ohmmeter to
insure good electrical connection with no shorting. Be sure that coax lengths and
types follow the avionics manufacturer’s recommendations.
Revision H
August 19, 1996 5
2.3.2 ANTENNAS
The three cardinal points for antenna installation are location, mounting and electrical
characteristics.
Antenna Location:
Provide an area where shadowing of the antenna will not occur (eg. blocking of the
signal by other parts of the aircraft). Remember that at VHF frequencies and above,
direct line of sight signals are required from ground stations to the antenna and for
maximum effective range. Consider that close proximity of an antenna to other
antennas or noise sources may create interference problems. Read carefully and
follow closely the recommendations of the antenna manufacturer about antenna
location.
Antenna Mounting:
Proper attachment of any antenna to the aircraft surface is of primary importance.
Carefully clean all paint and corrosion off the mounting surface and apply an anticorrosion treatment. Do the same to the inside surface if a backing or nut plate is to
be used. Mount the antenna securely per the antenna manufacturer’s
recommendations and check carefully to insure good electrical bonding. Do not
mount any antenna to doors, hatches, inspection plates or other moveable surfaces
because proper bonding to the aircraft surface cannot be accomplished. After proper
mounting and bonding is achieved, a bead of high quality RTV around the junction of
the antenna base and the aircraft surface will prevent water seepage and corrosion
from forming between the antenna base and aircraft surface.
Antenna Electrical Characteristics:
Use the antenna supplied with the avionics equipment, or if not supplied, the
antenna(s) recommended by the avionics manufacturer. If no specific antenna is
recommended, choose an antenna which provides good service for the frequency
range and the service conditions of the aircraft (eg. speed, altitude, etc.). If a signal
splitter is to be used, compare the specifications carefully to the application. Many
installation problems are encountered with improper application of signal splitters! If
in doubt, test the power and frequency characteristics of the splitter on the bench to
be sure.
Simple antenna problems such as shorting or open circuit problems can be determined
by use of an ohmmeter, although certain types of antennas may require use of ramp
test equipment to check radiation. But, by far, the most common antenna problems
are diagnosed to be coax or connectors, antenna bonding, or signal splitters. Never
allow an aircraft antenna to be painted.

2.3.3 WIRING AND HARNESSING
Construct the installation wiring harness carefully from the avionics manufacturer’s
wiring diagram. Be extremely careful to note recommended wire sizes, the need for
shielded wiring (if any), and decide upon any optional wiring to be included. Measure
carefully and plan the harness layout to avoid interference of the cable harness with
existing avionics, instruments or controls.
Remove the connector plates from the rear of the trays. Connect all wires to the
proper pin of each connector, checking as you go to insure that no loose strands cause
shorting to adjacent pins or to ground surfaces. We recommend tubing be placed
over each soldered pin connection to prevent wire strands from touching adjacent
connections. Be particularly careful with the shield braids of shielded wires. Do not
expose any more of the conductor than is absolutely necessary and keep the braid
connection as short as possible. Remember that on shielded wires only one ground
point is recommended. Follow manufacturer’s recommendation about where the
ground point should be located. After completing all connections, check wiring
with an ohmmeter again to ascertain that all connections are as desired and
that no undesired shorting to ground or other pins has occurred. Visually
double check to see that braids on shields are not creating shorting that no insulator
melting has occurred during soldering and pull firmly on all connections to insure good
mechanical bond.
Install the harness and connectors/connector plates in the aircraft with very
dress only.
Solder all connections to power and ground and install panel components/controls and
safety devices (eg. fuses or breakers). It is desirable at this point to insert all
equipment in trays and perform preliminary check-out. Following a satisfactory
check-out, and with all equipment in the properly installed location, complete the final
dressing and routing of the harness and secure in place.
Note:
It is extremely important that units should be installed in trays while final dress
and bundling of the harness is accomplished to assure proper alignment of
connectors between tray and unit. Failure to do this may cause problems
when unit is initially inserted into tray due to misalignment of connectors!
The final step is to perform a complete check of all avionics operations and insure that
free movement of all cockpit controls is available.
2.3.4 NOISE AND INTERFERENCE
The typical airframe is a small and imperfect platform for providing all of the antenna
ground planes and power sources and inter-wiring required for avionics operations,
particularly for a low noise and interference free expectation. This subject is far too
broad and complex to address in detail in a few paragraphs. However, an approach
to categorizing and defining the problem can be outlined.

2.3.3 NOISE AND INTERFERENCE (CONTINUED)
Noise and/or interference is usually heard in the audio systems, although it may also
be detected as an interference to indicator operation. Unless a strong suspicion of the
exact source is suspected, it is best to begin a process of elimination, in the following
order:
1. Power Source: Check for low voltage when the avionics load is
applied. A high resistance battery cell in the A/C can cause
numerous problems. View the avionics power line at the avionics
master and at the affected unit for noise on the power line. If
present, try to categorize the frequency (eg. alternator whine, which
may be caused by one or more bad alternator diodes, or if
interference is present only when a communication unit is
transmitting, etc.). If the noise is present or worse at the affected
unit than at the avionics master, investigate the harness for noise
coupling between wires. If necessary, disconnect the affected unit
power from the aircraft power source and connect to an external
power supply or battery.
2. Power Ground: View the power ground line at the avionics master
and the affected unit. If noise is discerned at the master source,
ground strapping may be corroded or partially broken. If only at unit,
a larger wire size or wire re-routing may be required.
3. Interference: Both noise and interference may be either conducted
or radiated, and in some cases electromagnetically coupled between
units. If it is determined that the noise or interference is eliminated
whenever another avionics unit is not transmitting, first investigate the
radiated alternative. Insure complete and proper bonding of antennas
to the aircraft surface, and check the coaxial cable and all shield
connections and connectors. Review the manufacturer’s
recommendations for antenna separations. Be aware that antenna
radiation directly to conductors at the rear of mounting trays or units
may occur if shields are stripped too far back from the connector or
are improperly grounded. Disconnecting the interfering antenna and
substituting an external dummy load may assist diagnosis. Conducted
interference usually occurs through paths which are shared by the
avionics equipment such as power lines, ground points, audio
equipment, or induced interference between adjacent wires or
harnesses. Review the manufacturer’s recommendations for
shielded wiring and ground points, and for separation of specific
wires. Measure ground points for a small but perceptible resistance
to true ground and view power lines with an oscilloscope, turning
each unit on and off to detect changes. Recheck common or
adjacent connections to jacks, plugs, or shared equipment such as
power converters, breakers, or audio panels.
4. Compromise: In some cases noise or interference may be subdued
but not eliminated. With the inefficient and imperfect platform
provided by the aircraft for antennas and power source, etc, complete

2.3.5 SUMMARY
The paragraphs above are not intended to be highly technical, completely thorough, or
extensive, but serve as a reminder for certain precautionary or follow-up procedures
for general avionics installations. Trimble is prepared to assist at any point with
additional information, hints, or literature. Simply call 1-800-487-4662 and ask for
technical assistance.
2.4 INSTALLATION
Installation of any equipment in an aircraft requires that the work be performed by a
Certificated Radio Repair Station with appropriate ratings. The installing agency must
complete an FAA Form 337 and compute a new weight and balance for the aircraft for
insertion in the Aircraft Flight Manual. Unless the mechanic is the designated inspector for a
Certificated Radio Repair Station or holds an Inspection Authorization, the work is subject to
inspection and approval of an FAA inspector or the holder of an Inspection Authorization.
elimination of the problem may be very expensive or impossible (eg.
if there is simply not enough space to provide ground plane or
antenna separation as recommended). Or, the aircraft strobe noise is
audible but not objectionable, etc. These problems should be
discussed early and thoroughly with the customer.
The following items and suggestions should be considered prior to installation of your Terra by
Trimble TN 200D Navigational Receiver.
1. Discuss the location of this receiver with your customer, preferably in a position that
provides ease of operation.
2. Avoid installing the TN 200D near heat sources. If unavoidable, insure additional
cooling is provided.
3. Insure that adequate clearance exists behind the panel for sleeve, connectors, and
additional cooling if required. A minimum of 14.00" (35.56 cm) is recommended.
4. Refer to Terra by Trimble TN 200D Outline Drawings for panel cut-out details and
mounting dimensions as well as pertinent notes.
5. Install the sleeve assembly in the instrument panel. Insure compliance with standards
set forth in the FAA Aircraft Inspection and Repair Document AC 43.13-2A.
Note:
Insure that the sleeve is installed with the large opening toward the top.
6. The 15 pin “D” connector assembly supplied with the Terra by Trimble TN 200D
must be wired correctly to the aircraft avionics systems or severe damage may result
to the Terra by Trimble TN 200D or other systems. The interconnecting wiring for
the 15 pin “D” connector is shown in Figure 3-6 (without glideslope) and Figure 3-7
(with glideslope). Comply with standards set forth in FAA Aircraft Inspection and
Repair Document AC 43.13-1A Section 7 and other pertinent FAR’s as required.
Insure MIL-SPEC wire is utilized for all interconnects.
Revision H
August 19, 1996 9
2.4 INSTALLATION (CONTINUED)
CAUTION: The operating voltage of this Terra by Trimble TN 200D is
13.75 V nominal for direct connection to an aircraft 12-14 volt electrical
system. If the aircraft electrical system supply is 24-28 volt, it will be
necessary to employ a converter to reduce the 28 volts to 13.75 volts for the
Terra by Trimble TN 200D. Terra by Trimble can supply an optional
converter specifically designed for this purpose. It is Terra by Trimble P/N
0900-3219-12, Model MLC 28-5.
7. Install the TN 200D in the mounting tray assembly. Use caution as the rear
connectors mate. After the float mounts are positioned correctly (a little twisting at
the front panel may be necessary), the unit will fully engage the connectors with light
to medium pressure on the front panel.
CAUTION: DO NOT PUSH UNIT INTO TRAY WITH THUMBS
ON LENS AS DISPLAY DAMAGE MAY RESULT!
Insert a 7/64" Allen wrench in the front panel hole and engage the locking screw.
Turn clockwise until the cam has engaged itself in the tray and is moderately
tightened. Use caution to prevent stripping the threads on the locking cam or screw.
To remove the unit from the mounting tray, insert the 7/64" Allen wrench in the
locking screw and turn counterclockwise. The cam will move the unit outward about
1/4" and disengage the connectors. The unit may now be pulled out of the mounting
tray by hand.
8. The connector bracket is mounted from the front side of the sleeve with two Phillips
head screws and lock washers. As viewed from the front of the unit, pin 1 of the
connector is top right and pin 15 is bottom left.
2.5 ANTENNA INSTALLATION
A 50 ohm horizontally polarized navigational antenna is recommended. Insure tested speed of
the antenna matches top speed of the aircraft. Connect the antenna to the Terra by Trimble
TN 200D using standard 50 ohm coaxial cable such as RG 58A/U. Terminate the cable with
BNC coaxial connectors as required. Ohm out the coax to insure no shorts are present.
Select a location providing a clear line of sight and symmetrical to the centerline of the
aircraft. Insure proper bonding of the antenna to the aircraft.
2.6 OPERATIONAL CHECKOUT
1. Rotate OFF/ON/VOLUME/IDENT (left side) knob clockwise past the detent to turn
receiver on. This will also supply power to the indicator if it is connected to switched
power out.
2. Rotate TUNE (right side) knob to obtain the desired frequency in the right hand
window. Verify that the faster the knob is rotated the more the frequency changes
with each detent.
3. Press the “<—>” (TRANSFER) button and verify that the two frequencies “swap”
sides in the display.
4. Rotate the ON/OFF/VOLUME/IDENT knob clockwise and verify white noise on the
audio out. If a VOR station is within range, verify that whenever the left knob is
depressed the ident is eliminated from the audio output and with the knob pulled out all
the received audio is applied to the audio output.
10
Revision H
August 19, 1996
2.7 FINAL INSPECTION
1. Insure that all wiring is properly routed and secure. Dress harnessing neatly and
secure in place with cable ties. Check connector integrity and locking devices.
Insure locking devices are functioning properly and are secured. Verify cabling is not
“clotheslined” and provisions have been made for service loops. Pull yoke to its
maximum travel. While slowly returning yoke to its normal position, rotate yoke left
and right to insure all cabling is routed and tied up properly. Cycle rudder pedals and
verify that they are free and cables are unobstructed. Install gust locks, perform
complete checkout of all avionics including dimmers. Secure aircraft power and all
master switches.
2. Have installation inspected by someone authorized under Federal Aviation Regulation
Part 65.
3. Add the Terra by Trimble TN 200D to the aircraft equipment list, including serial
number. Complete FAA Form 337 if required, and make required airframe logbook
entries. A weight and balance change may be required, depending on the type of
aircraft.
4. Complete warranty card and return to Trimble.

Insure your new TN 200D is turned off until after engine start-up procedures
are completed. This precaution will greatly improve the lifetime of all of
your avionics as well as your TN 200D.
After 5 seconds the displays will revert back to the last used frequencies.
Enter your desired frequency into the standby (right hand) window, by turning the tune knob
on the right-hand side. The faster this knob is rotated the more the frequency changes with
each detent. Clockwise tuning increases the frequency and counterclockwise tuning
decreases the frequency. At the upper and lower limits of the frequency band, i.e., 108.00
and 117.95, the frequency will “wrap around”. This allows faster tuning from one end of the
band to the other.
After the desired frequency is obtained, simply press the <—> (TRANSFER) button to move
the frequency into the left-hand or “active” window and your previously used frequency to
the right-hand or “standby” window.
4.4 IDENT OPERATION
Whenever the left hand knob is depressed the ident is eliminated from the audio output and
only voice is heard. With the knob pulled out the voice and ident are heard.

4.5 ILS AND DME CHANNELING OPERATION
If your TN 200D is equipped with the glideslope receiver, anytime an ILS frequency is
selected in the active window the glideslope receiver is automatically channeled to the
appropriate frequency. At all times DME channeling is being produced on the glideslope
board.
4.6 FREQUENCY TRANSFER
As previously described in Section 4.3, simply pressing this button will “swap” frequencies
between active and standby windows.
As will be covered in the next section, depressing this button also cancels the channel
memory display.
The transfer button must be used in order for the last used frequencies to be displayed after a
power interruption. For example, say you are tuned to 108.00 in the active display and
116.60 in the standby display. Pressing the transfer button will insure that the unit will
display 116.60 108.00 after any power interruptions. Failure to do this transfer will cause
the unit to come up with 108.00 in the active display and the last transferred frequency in the
standby display.
4.7 TO PLACE FREQUENCIES IN MEMORY
The TN 200D has a 10 user programmable memories. To place frequencies in memory, push
the tune knob in. In between the active and standby window, “O” will be displayed. After
rotating the tune knob 1 detent from “O” an “M” will appear in the display beside the
number. Rotating the tune knob, while holding it in, will increment or decrement the channel
number from 0 through 9 or vice-versa. After you obtain the desired channel number, simply
release the knob and rotate the tune knob to your desired storage frequency. Press the “STO”
(STORE) button and that frequency is now entered in the indicated channel memory.
EXAMPLE:
At your airport, the following frequencies are used:
VOR 113.20
ILS Approach 110.30
For simplicity, lets assign channel numbers in this same order. To enter these in memory,
follow these steps:
Push tune knob: XXX.XX 0 XXX.XX
Hold in and rotate: XXX.XX 1m XXX.XX
Release and tune: XXX.XX 1 113.20
Press “STO”: XXX.XX 1m 113.20
Push tune knob and hold: XXX.XX 1m 113.20

Revision H
August 19, 1996
4.7 TO PLACE FREQUENCIES IN MEMORY (CONTINUED)
Rotate tune knob: XXX.XX 2m XXX.XX
Release and tune: XXX.XX 2 110.30
Press “STO”: XXX.XX 2m 110.30
Continue until all frequencies that are desired are “loaded in”. After the frequencies are
loaded, you are ready to recall them at any time.
4.8 MEMORY/CHANNEL MODE
Cycle power to the TN 200D, after initialization push tune knob and rotate to “1m”. Press
transfer button and 113.20 moves to the active window. The previously displayed frequency
moves to the standby window, and 1m is cleared from the display. To gain access to any
channel, simply push the tune button in, rotate to desired channel, press the transfer button,
and you are on your desired channel.

This section is to instruct the owner/operator in the proper “care and feeding” of their new
Terra by Trimble TN 200D Navigational Receiver.
4.2A OPERATION
See Figure 4-2 on page 33 for locations and descriptions of the TN 200D Front Panel
Controls.
4.3A NAV TUNING KNOB OPERATION
Pushing the tuning knob in for approximately one-third of a second will cause the last two
digits of the MHz (Example 1
since it never changes.

XX.XX) standby display to blink. The leading 1 remains solid
Rotating the knob will now tune the MHz. Scrolling past the end of the frequency range (up
or down) will cause the frequency to “wrap around” to the other end of the range (e.g.,
scrolling up past 117, wraps to 108).
Pushing the knob again for approximately one-third of a second will shift the cursor control
from MHz to kHz (Example lXX.
XX) causing the MHz digits to light steady and the kHz
digits to blink.
In the same manner as above, rotating the knob will now tune kHz.
Pushing the knob again for approximately one-third of a second will cause all digits to
display steady.
Notes:
1. Pushing the button at any time during the tuning sequence will cause the
frequency in the standby display to switch to active and the active to standby
as well as canceling the cursor tuning, if activated.
2. The software will not let the user select an invalid frequency i.e., below
108.000 or above 117.950.
3. Tuning with the continuous mode is still available without utilizing the
cursor.

4.4A IDENT OPERATION
Whenever the left hand knob is depressed the ident is eliminated from the audio output and
only voice is heard. With the knob pulled out the voice and ident are heard.
4.5A ILS AND DME CHANNELING OPERATION
If your TN 200D is equipped with the glideslope receiver, anytime an ILS frequency is
selected in the active window the glideslope receiver is automatically channeled to the
appropriate frequency. At all times DME channeling is being produced on the glideslope
board.
4.6A MEMORY OPERATION
Pressing the MEM button will call up the last used or programmed memory position.
Repeatedly pushing the MEM button will cycle upwards through the memory positions.
Alternately, holding the MEM button in will cause the unit to cycle through the memory
positions at a rate of one position every one-third of a second.
4.7A TO PROGRAM NEW FREQUENCIES IN MEMORY
Press MEM to select the desired memory position. The “M” will illuminate between active
and standby frequencies. Tune the new frequency using either the continuous or cursor
programming method. As soon as the frequency value changes from the stored frequency, the
“M” light goes out.
Press MEM again to store the new frequency. The “M” relights to confirm storage.
Use the button to move the new memory frequency to active side and repeat these steps to
store additional frequencies in memory.
Note:
If the button is pressed before storing the new frequency into memory; the
radio will drop out of program mode and the new frequency will not be
stored.

4.8A DISPLAY BLANKING OPERATION
(RECOMMENDED FOR GLIDERS AND BATTERY-POWERED A/C ONLY)
Press the tuning knob first and then the MEM button. Hold both in for approximately four
seconds. The display will go into a blank condition.
If the display has blanked, moving the tuning control, pressing the button, or pressing the
MEM button will restore the display. Specifically, the first press of the button, the first
“click,” or first push of the tuning knob will restore the display with no changes (e.g., the
frequency will not transfer or change). Once the display has relit, the unit will function
normally. However, pressing the MEM button will restore the display and recall the last
Memory position to the standby display.
If no tuning control (button, MEM button, or tuning knob) is moved for a period of 15
seconds, the frequency displays (both active and standby) will blank.
To cancel blanking operation, turn function knob to “off” then turn back on. The unit will
then operate in normal mode.
