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 UNIT. 2.1 ANTENNA CONSIDERATIONS 2.1.1 GPS ANTENNA LOCATION The UNITS GA 56 Antenna must be mounted on top of the aircraft. 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 GPS antenna installation.
Av. Kit Install. Manual 190-00067-62 Rev. E Page 8
For rotorcraft, locate the GA 56 antenna: 1) As far from the main rotor hub as possible. This reduces the percentage of time the blade blocks the antenna. 2) As far below the blade surface as possible if installing the antenna under the blade. This reduces signal distortion caused by the blades. The antenna should be located at least 3 feet from transmitting antennas such as VHF Comm, HF transmitter, DME, Transponder, and Radar. 2.1.2 COMM ANTENNA LOCATION (GNC 250/GNC 250XL only) The COMM antenna should be well removed from all projections, engines and propellers. The ground plane surface directly below the antenna should be a flat plane over as large an area as possible (18 inches square minimum). The antenna should be mounted a minimum of 6 feet away from any DME antennas, 4 feet from any ADF sense antennas, and a minimum of 3 feet from the UNITS and its GPS antenna. The UNITS COMM antenna connector is specified to have installed GPN 330-0006700 (1.57542 GHz notch filter) to minimize interfering harmonics. 2.1.3 ELECTRICAL BONDING No special precautions need to be taken to provide a bonding path between the GPS antenna and the aircraft structure. Follow the manufacturers instructions for the COMM antenna. (GNC 250/GNC 250XL only) 2.1.4 ANTENNA LIMITATIONS GARMIN'S GA 56 Antennas are recommended for installations where the airspeed of the aircraft will be subsonic. See the COMM antenna specification for its limitations. (GNC 250/GNC 250XL only) 2.1.5 VHF COMM INTERFERENCE OF GPS On many panel-mounted aircraft, VHF COMM's can radiate strong harmonics from both the comm itself and its antenna. The GNC 250/GNC 250XL COMM section will not interfere with its GPS section. However, placement of the UNITS GPS antenna relative to all COMM's and COMM antenna, including its own, is critical. Use the following guidelines, in addition to others in this document, when locating the UNIT and its antennas.
Av. Kit Install. Manual 190-00067-62 Rev. E Page 9

GPS Antenna:

Locate as far as possible from all COMM antennas and all COMMs (including the GNC 250/GNC 250XL). The GPS antenna will be much less sensitive to COMM antennas that use a 1.57542 GHz notch filter. Locate as far as possible from all COMM antennas.

If a COMM antenna is found to be the problem, a 1.57542 GHz notch filter (GPN 33000067-00) may be installed in the VHF COMM coax, as close to the COMM as possible. This filter (GPN 330-00067-00) is required for the GNC 250/GNC 250XL transmitter. If a COMM is found to be radiating, the following can be done: 1) Replace or clean VHF COMM rack connector to assure good coax ground. 2) 3) Place a grounding brace between the GNC 250/GNC 250XL/GPS 150XL, VHF COMM, and ground. Shield the VHF COMM wiring harness.
2.1.6 COMM ANTENNA INSTALLATION INSTRUCTIONS (GNC 250/GNC 250XL only) The COMM antenna should be installed according to the manufacturer's recommendations. 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 pilots 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
The recommended antenna cable type for both antennas is M17/155-0001 (RG-58A/ U) per MIL-C-17. Maximum allowable length for the GPS antenna using this cable type is 40 feet. Other cable types with 50 ohms nominal impedance and longer lengths can be used for the GPS antenna, provided the installer insures that the attenuation does not exceed 10dB at 1.5 GHz for the specific installation. Check that there is ample space for the cabling and mating connectors. Avoid sharp bends in cabling, particularly the COMM antenna cable (GNC 250/GNC 250XL only), and routing near aircraft control cables. Cabling for the UNIT should not be routed near components or cabling which are sources of electrical noise.
Av. Kit Install. Manual 190-00067-62 Rev. E Page 10
Do not route the COMM antenna cable near any ADF antenna cables. (GNC 250/GNC 250XL only) Route the GPS antenna cable as far as possible away from all COMMs and COMM antenna cable. 2.4 COOLING AIR
Cooling air is highly recommended for the UNIT, but not required. Cooling is recommended to maximize display performance for the GNC 250XL and GPS 150XL. As with any electronic equipment, reduced operating temperature can contribute to increased reliability. Additionally, location of the UNIT in a stack of other power dissipating equipment can produce unacceptably high ambient air temperatures around the unit. A 5/8 inch diameter air fitting is provided on the rear of the mounting rack for the purpose of admitting cooling air under such conditions. 2.5 ANNUNCIATORS

If the installation includes any electrical interface with other flight instruments, an annunciator may be required. Refer to current FAA directives. 2.6 EXTERNAL ALTITUDE INPUT
Pressure altitude input from an external source is not required but it may benefit the UNITS system performance during times of minimal satellite coverage or poor satellite geometry. Pressure altitude input from an external source may be derived from a RS-232 compatible serial altitude input or Parallel Greycode/Gillham Altitude (GNC 250/GNC 250XL only) as described in Section 4 of this manual. Gillham Altitude is not required when serial altitude is used.

RACK INSTALLATION

A. Figure 3-4 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 UNIT for portable use. Deformation of the rack may make it difficult to install and remove the UNIT. B. Install the rack in the aircraft panel using four #6-32 countersunk screws and four self-locking nuts or other FAA approved methods as per Advisory Circular 43.13-1A. The screws are inserted from the inside through the holes in the sides of the rack (see Figure 3-5). 3.5 UNIT INSTALLATION AND REMOVAL

The UNIT is installed in the rack by gently sliding it straight in until it rests against the back of the rack. A 3/32 inch hex drive tool is then inserted into the access hole at the bottom of the unit face. Rotate the hex tool clockwise while pressing on the left side of the Bezel until the unit is firmly seated in the rack. To remove the unit from the rack, insert the hex drive tool into the access hole on the unit face and rotate counter-clockwise until the mounting screw turns freely and the unit protrudes about 3/8 inch from the panel. Be sure not to over tighten the unit into the rack. The application of hex drive tool torque exceeding 15 in*lbs can damage the locking mechanism. 3.6 COMM ANTENNA INSTALLATION CHECK (GNC 250/GNC 250XL only)
Check for insertion loss and VSWR. VSWR should be checked with an in-line type wattmeter inserted in the coaxial transmission line between the transceiver and the antenna. Any problem with the antenna installation will most likely be seen as a high reflected power. A VSWR of 3:1 will result in a 25% loss in power. 3.7 PLACARD
After completing the installation, a placard stating that the UNIT is limited to VFR use 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 unit, or a suitable equivalent.
SECTION 4 POST INSTALLATION CONFIGURATION & CHECKOUT PROCEDURE

See Section 4.1 to get to this page. 4.3.1 POWER TEST Select the Power Test page. This page reports the status of the UNIT external power source, remote battery and internal memory battery. In the below voltage represents the voltage currently measured for that function.
Av. Kit Install. Manual 190-00067-62 Rev. E Page 19
The first line of power information shows the source of external power as shown below: External Power voltage Battery Power Wall Adapter The presence of a Wall Adapter will overide the other two sources. Battery Power will not be shown unless on the Configuration Page the Remote Battery is selected as Installed. The higher voltage of External Power or Battery Power will determine which is shown. The next line shows the status of the Remote Battery as shown below: Rmt Pak none (If on the Configuration page Remote Battery is selected as none) Rmt Pak voltage mode auto status mode represents the mode of the charger enable to the remote battery pack and is selectable. On enables the charger. Off disables the charger. Auto enables the charger if the External Power is the current source and its voltage is high enough. When in Auto mode auto status will be either on or off reflecting whether the charger is enabled or disabled. The next line reports the status of the internal memory battery as shown below: Mem Batt ok/low. Note that the TX field will light on the display but the transmitter will not actually transmit when the UNIT is powered from the wall charger. 4.3.2 CDI AND FLAG TEST Select the the CDI Test Page. Using the controls on the UNIT front panel, make the selections indicated below and verify the interfaces as appropriate: CDI Full scale left Full scale right Centered Ensure the CDI is deflected full scale left (5 dots) Ensure the CDI is deflected full scale right (5 dots) Ensure the CDI is centered Ensure TO flag is visible Ensure FROM flag is visible Ensure TO and FROM are NOT visible Ensure CDI flag is in view Ensure CDI flag is out of view

b) See that the NAV flag is out of view c) Select 121.15 MHZ on COMM1
Av. Kit Install. Manual 190-00067-62 Rev. E Page 22
d) Transmit for a period of 20 seconds e) f) Verify that the flag does not come into view Repeat steps d) and e) for the following frequencies: 121.175, 121.20, 131.250, 131.275 and 131.300 g) Repeat steps c-f for all COMMs installed in the aircraft
h) If the NAV flag comes into view, refer to Section 2.1.5 for options to improve performance. 4.3.10 VHF COMM CHECK (GNC 250/GNC 250XL only) A flight test is recommended after the installation is completed to insure satisfactory performance. To check the communications transceiver, maintain an appropriate altitude and contact a ground station facility at a range of at least 50 nautical miles. Contact a ground station close in. Press the squelch disable button to defeat the automatic squelch feature and listen for any unusual electrical noise which would reduce the COMM receiver sensitivity by increasing the squelch threshold. If possible, verify the communications capability on both the high and low end of the VHF COMM band.

SECTION 5 CERTIFICATION

The GNC 250/GNC 250XL/GPS150XL is certified to the airworthiness criteria in Advisory Circular 20-138 for VFR use in the en route and terminal phases of flight. The GNC 250/GNC 250XL/GPS 150XL initial certification was accomplished via a STC by GARMIN in a Mooney M20J. See Appendix C for a copy of each STC. All installations must be certified. For more information, see FAA Advisory Circular "Airworthiness Approval of Global Positioning System (GPS) Navigation Equipment for use as a VFR and IFR Supplemental Navigation System", Appendix 1. All new certifications after GARMIN's Mooney installation will be "Follow-On".
SECTION 6 CONTINUED AIRWORTHINESS
Maintenance of the GPS 150XL/GNC 250/GNC 250XL is on condition only. Periodic maintenance of the GPS 150XL/GNC 250/GNC 250XL is not required.

CONNECTOR CHANGES
STAMPED CONTACT CONNECTOR USAGE
Garmin panel mount GPS radios have previously been shipped with stamped crimp type contacts. All products are now being shipped with machined mil-spec contacts with color-coded barrels. The following figures can be used to identify which type contact you have:
Some contacts are pins as shown, while others are the socket type. The type used will vary with the installation. When working with the stamped crimp type contacts, the following tools should be used: Tools supplier Amp ITT Cannon Cinch 37 and 9 position connectors Crimp Tool Extraction Tool 58448-2 91067-22 995-2000-000 980-0008-124 HTD-544 CIET-20-HDB 26 position connector Crimp Tool Extraction Tool 90430-1 91285-1 995-2000-022 980-00004-804 HTD-544 HTD-520
Part numbers shown are not maintained by Garmin and consequently are subject to change without notice. When stamped contacts are used special considerations must be made for aircraft power and remote battery (optional) connections, as shown in the following diagram:
Av. Kit Install. Manual 190-00067-62 Rev. E Page 39
REMOTE BATTERY PIN ASSIGNMENTS
A change was made to the remote battery connectors starting with serial numbers 33050055. Units with lower serial numbers have pin contacts on the battery pack. Units 33050055 and up use socket contacts on the battery and the pin number assignments are different, however the individual contact locations are unchanged. The following table shows the pin assignments for the two different types of connectors:
