(Pins 3 and 6) loads, 375 millivolts for flag out-of-view, and
+40 millivolts for flag in-view.
OBI data: Output providing bearing to waypoint data for a
(Pins 7, 8, and 12) Bendix/King RMI (KI 229 or equivalent).
Message annunciators: Output capable of driving negative or positive logic
(Pins 9 and 11): annunciators.
Message audio: Output capable of producing 10 milliwatts into 500
(Pin 10) ohms at a frequency of 2 KHz.
RS232 data: Output capable of driving ARGUS3000/5000/7000
(Pin 13) and STORMSCOPE SERIES II with NAVAID moving
map displays and Shadin fuel management system.
Conforms to the EIA specification RS-232C.
SECTION 2 INSTALLATION CONSIDERATIONS
Careful planning and consideration of the suggestions in this section are required to
achieve the desired performance and reliability from the GPS 100.
2.1 ANTENNA CONSIDERATIONS
2.1.1 SATELLITE VISIBILITY
The GPS 100 Blade or Low Profile Antenna must be mounted on top of the aircraft in
the upright position. For best performance select a location with an unobstructed
view of the sky above the aircraft when in level flight. Figure 2-1 illustrates a typical
blade antenna installation. Recommended installation locations for the Low Profile
Antenna are the same.

Av. Kit Install. Manual
190-00004-00 Rev. G
Page 7
2.1.2 NOISE SOURCES
The antenna should be located at least 3 ft from transmitting antennas such as VHF
Comm, HF transmitter, DME, Transponder, and Radar. Cabling for the GPS 100
should not be routed near components or cabling which are sources of electrical noise.
2.1.3 ELECTRICAL BONDING
No special precautions need to be taken to provide a bonding path between the
antenna and the aircraft structure.
2.1.4 ANTENNA LIMITATIONS
The GPS 100 Blade and Low Profile Antennas are recommended for installations
where the airspeed of the aircraft will be subsonic. For aerodynamic considerations,
the Low Profile Antenna is recommended for operation above 200 kts.
2.2 RACK CONSIDERATIONS
2.2.1 ACCESSIBILITY
Plan a location which gives the pilot complete and comfortable access to the entire
keypad and which is plainly visible from the pilots perspective. Check that there is
adequate depth for the rack in the instrument panel. A location away from heating
vents or other sources of heat generation is optimal. Figure 2-2 illustrates a typical
aviation rack installation.
2.3 CABLING AND WIRING
Use only the antenna cable supplied in the installation kit. Other cabling may lead
to degraded performance. Check that there is ample space for the cabling and mating
connectors. Avoid sharp bends in cabling and routing near aircraft control cables.
2.4 ANNUNCIATORS
If the installation includes any electrical interface with other flight instruments, an
annunciator may be required. Refer to current FAA directives.

3.2 ANTENNA INSTALLATION
The Blade Antenna outline and footprint dimensions are shown in Figure 3-1. The Low
Profile Antenna outline and footprint dimensions are shown in Figure 3-1A. Both
antennas require the same Installation procedure.
A. Using the backing plate as a template, mark the location of the mounting holes and
the through hole for coax cable. Drill or punch the holes.
B. The antenna installation must provide adequate support for the antenna consid-
ering a maximum drag load of 14 lbs (at subsonic speed). Install a doubler plate to
reinforce thin skinned aircraft. Observe guidelines for acceptable installation
practices as outlined in AC 43.13-2A.
C. Seal the antenna and gasket to the fuselage using a good quality electrical grade
sealant. Use caution to insure that the antenna connector is not contaminated with
sealant. Insure that the mounting screws are fully tightened and that the antenna
base is well seated against the gasket. CAUTION: Do not use construction grade RTV
sealant or sealants containing acetic acid. These sealants may damage the electrical
connections to the antenna. Use of these type sealants may void the antenna
warranty.
3.3 CABLE INSTALLATION
A. Route the coax cable supplied to the rack location keeping in mind the recommen-
dations of Section 2. Secure the cable in accordance with good aviation practice.
B. Trim the supplied RG-59/U cable to the desired length and install the BNC
connector (330-00017-00) per the cabling instructions on Figure 3-2.
3.4 RACK INSTALLATION
A. Figure 3-3 shows outline dimensions for the aviation rack. Install the rack in a
rectangular 6.320" x 2.000" hole in the instrument panel. Exercise caution when
installing the rack into the instrument panel. The rack is designed to facilitate removal
of the GPS 100 for portable use. Deformation of the rack may make it difficult to install
and remove the GPS 100.
B. Install the rack in the aircraft panel using four #6-32 countersunk screws and
four self-locking nuts. The screws are inserted from the inside through the holes
in the sides of the rack (see Figure 3-4).

3.5 AVIATION INTERFACE SET-UP
Before installing the GPS 100 into the aviation rack, several operating parameters
need to be set-up so that the GPS 100 can interface properly with the aviation rack
and other avionics. Press the ON button. The Initialization page will appear. See
Chapter 3 in the GPS 100 Owners Manual for information on initialization. Approve
the initialization page.
There are several set-up pages which can be viewed by pressing the SET key. Press
the SET key until the CDI SETTINGS page is displayed. Move the cursor to highlight
the setting for STEER TO. Press the clear key until D-BAR appears. Move the cursor
to highlight the OK and press ENT. Press the SET key to continue through the set-
up pages and set-up the following parameters:
STEER TO> D-BAR
OUTPUT> AVIATION
Ensure that the following parameters are set-up properly for your application. The
following are typical settings for an aviation environment. See Chapter 10 in the GPS
100 Owners Manual for more information on customizing the GPS 100 settings:
CDI SCALE>+ 5.00
>AUTO MAG
NAV> nm kt
ALT> ft FPM
DATUM> WGS 84 or as indicated on navigation charts for the area.
3.6 GPS 100 INSTALLATION
To install or remove the GPS 100 from the aviation rack, see the addendum to the GPS
100 Owners Manual included in the installation kit. This addendum should be given
to the end user.
3.7 PLACARD
After completing the installation, a placard stating GPS limited to VFR use only must
be installed on the panel in clear view of the pilot. The placard may be Garmin p/n
161-00024-00 as supplied with the installation kit, or a suitable equivalent.
SECTION 4 CHECKOUT PROCEDURE
In order to verify the installation, the aircraft must be outside the hanger and well away
from any buildings or aircraft that might block satellite signals. To perform the
checkout procedure it is necessary to be familiar with operating the GPS 100 or to have
the GPS 100 Owners Manual available for reference.

Av. Kit Install. Manual
190-00004-00 Rev. G
Page 11
With power applied to the aviation rack turn the GPS 100 on. The Self-Test Page will
be displayed followed by the Initialization Page. The GPS 100 must be properly set-
up per the instructions in Section 3.5 before performing the checkout procedure. Prior
to approving the Initialization page verify the following interfaces as appropriate:
CDI Ensure the CDI is deflected half scale left (2.5 dots).
TO/FROM Ensure the TO/FROM flag is in a TO condition.
NAV FLAG Ensure the NAV FLAG is out of view.
MESSAGE ANNUNCIATOR Ensure the message annunciators are illuminated.
RMI Ensure the RMI indicates 315o.
Approve the Initialization page, select the GPS Status page from Navigation Menu 1
(see Chapter 9 for more information on the GPS Status page). The process of satellite
acquisition is fully automatic and under normal circumstances will require 2-3
minutes to obtain navigation information (15 minutes or less when searching the sky).
If unable to acquire satellites, relocate the aircraft away from obstructions which
might be shading reception. If the situation does not improve, check the antenna
installation.
AUDIO
Select the Event Timer 1 page from Navigation Menu 2 (see Chapter 10 of the GPS 100
Owners Manual for more information on event timers). Set the count down timer to
go off in 1 minute. Prior to viewing the message indicating TIMER 1 EXPIRED (while
the "M" character is flashing in the upper right hand corner of the display), ensure the
audio interface is operating properly.
ARGUS 3000/5000/7000 or STORMSCOPE SERIES II with NAVAID or SHADIN FUEL
MANAGEMENT SYSTEM
Once GPS position information is available, use the AutoStoreTM function to store a
waypoint at your current position (see Chapter 8 of the GPS 100 Owners Manual for
information on the AutoStoreTM function). After storing your location, GOTO the stored
waypoint (see Chapter 6 of the GPS 100 Owners Manual for information on the GOTO
function). Ensure the ARGUS or STORMSCOPE or SHADIN fuel management system
are receiving data from the GPS 100 and are functioning properly.
