SECTION I
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.
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.

SECTION II
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
theequipment,performthefollowinginspections:
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 not return it to Trimble or its representatives.
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
anotherlocation.
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.

2.3.2 ANTENNAS
The three cardinal points for antenna installation are location, mounting and electrical
characteristics.
AntennaLocation:
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.
AntennaMounting:
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 anti-
corrosion 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.
