2.5 Antenna Considerations This section contains mounting location considerations for the antennas required for the GTR 200/200B. For mounting the COM antenna, refer to the aircraft manufacturer’s data. 2.5.1 COM Antenna Location The GTR 200/200B COM 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 inch square, minimum).

NOTE Canadian installations are required to meet Industry Canada specifications for maximum radiation as documented in Radio Specifications Standard 102 (RSS-102). For more information about RF exposure and related Canadian regulatory compliance, contact: Manager, Radio Equipment Standards Industry Canada 365 Laurier Avenue Ottawa, Ontario K1A 0C8 In accordance with Canadian Radio Specifications Standard 102 (RSS 102), an RF safety...
2.6 Mounting Considerations The GTR 200/200B is designed to mount in the avionics stack in the aircraft instrument panel within view and reach of the pilot. The primary unit location should minimize pilot head movement when transitioning between looking outside of the cockpit and viewing/operating the GTR 200/200B. The location should be such that the GTR 200/200B unit is not blocked by the glare shield on top, or by the throttles, control yoke, etc.
2.7.2 CAN Bus Considerations The CAN (controller area network) bus (Figure 2-1) is an interface format used to establish communication between several LRUs in the G3X system. Each end of the CAN bus “backbone” must be terminated. Each node length (distance from CAN bus backbone to each LRU) must be 0.3 meter or less in length (keeping the node lengths as short as practicable is recommended).
2.8 Air Circulation and Cooling The GTR 200/200B unit meets all requirements without external cooling. However, as with all electronic equipment, lower operating temperatures extends equipment life. Reducing the operating temperature by 15° to 20°C (27° to 36°F) reduces the mean time between failures (MTBF). Units tightly packed in the avionics stack heat each other through radiation, convection, and sometimes by direct conduction.
If the unit is damaged, notify the carrier and file a claim. To justify a claim, save the original shipping container and all packing materials. Do not return the unit to Garmin until the carrier has authorized the claim.
3.3 Backshell Assembly Refer to Appendix A for backshell and Shield Block ground assembly instructions. 3.4 Mounting Requirements 3.4.1 Rack Installation Use the dimensions shown in Appendix C to prepare the mounting holes for the unit. You may also use the GTR 200/200B unit mounting rack itself as a template for drilling the mounting holes.
3.5 Antenna Installation and Connections The GTR 200/200B requires a standard 50 vertically polarized antenna. Follow the antenna manufacturer’s installation instructions for mounting the antenna. The antenna should be mounted on a metal surface or a ground plane with a minimum area of 18 inches x 18 inches.
3.6 Post Installation Configuration and Checkout Procedures 3.6.1 System Configuration Overview This section contains checks to ensure the system is properly installed and functioning correctly as well as instructions for configuring the GTR 200/200B to the specific installation.

3.6.7 Flight Checks 3.6.7.1 COM Flight Check After the installation is complete, perform the following required flight checks to ensure satisfactory transceiver performance. Check the communications transceiver at a range of at least 50 nautical miles: (This check verifies unit receiver sensitivity test and transmitter range) 1.
The Software Update page (Figure 3-17) allows the installer to load unit software using a micro SD software loader card. Section 3.7.3 lists instructions on creating the loader card NOTE Garmin recommends the use of a Sandisk® brand 4GB micro SD card for updating unit software. Figure 3-17 Software Update Page 190-01553-00 GTR 200/200B Installation Manual Rev.
2. Download the GTR 200/200B System software to your PC. 3. Ensure that you have a micro SD card (Garmin recommends a Sandisk® brand 4GB micro SD card) connected to the PC in the micro SD card slot or by using an SD card adapter that allows a micro SD card to be used.
GTR 200B reboots. While a Bluetooth firmware update is being performed in the GTR 200B, the status on the Bluetooth menu page in normal mode will report UPDATING FIRMWARE. When the Bluetooth update is completed, the Bluetooth functions will return to normal operation.
NOTE Once disabled, the GTR 200B Bluetooth function does not remain disabled after turning the unit off and back on. The GTR 200B Bluetooth function is always enabled following a power cycle. 3.9 Continued Airworthiness Other than for regulatory checks, maintenance of the GTR 200/200B is ‘on condition’ only. Periodic maintenance of the GTR 200/200B is not required.

4.11 Receiver Audio RECEIVER AUDIO OUT is a 40 mW audio output that is intended to drive a recording device or an audio panel. RECEIVER AUDIO OUT supplies 40 mW (4.9 Vrms) into a 600 load, and is generally connected to the audio panel (if used).
4.14 Discrete Inputs These discrete inputs are active low and are configurable. Active-Low discrete inputs are considered active if either the voltage to ground is ≤3.5 VDC or the resistance to ground is ≤375 Ω. These inputs are considered inactive if the voltage to ground is 6.5-33 VDC or the resistance to ground is >100 kΩ.
APPENDIX A SHIELD BLOCK CONNECTOR INSTALLATION INSTRUCTIONS A.1 Shield Block Installation Parts Table 2-3 and Table A-1 list the parts needed to install a Shield Block. Parts listed in Table 2-3 supplied in the GTR 200/200B Connector Kit (011-003240-00) and the GTR 200/200B Connector Kit FAA-PMA (011-003240-01).

Page 55
Connect a Flat Braid (item 4, Figure A-2) to the shield exposed through the window of the prepared cable assembly from step 2. The Flat Braid should go out the front of the termination towards the connector. It is not permitted to exit the rear of the termination and loop back towards the connector (see Figure A-2).
Secondary Method: Solder a Flat Braid (item 4, Figure A-2) to the shield exposed through the window of the prepared cable assembly. Ensure a solid electrical connection through the use of acceptable soldering practices. Use care to avoid applying excessive heat that burns through the insulation of the center conductors and shorts the shield to the signal wire.
Page 57
NOTE Refer to Figure A-1 for all item numbers in the following steps 6-13. 6. Insert newly crimped pins and wires into the appropriate connector housing location as specified by the installation wiring diagrams. 7. Cut the Flat Braid (item 6) to a length that, with the addition of a ring terminal, will reach one of the tapped holes of the Shield Block backshell (item 1).
A.3 Shield Termination Technique - Method A.2 (Daisy Chain) In rare situations where more braids need to be terminated for a connector than three per ring terminal it is allowable to daisy chain a maximum of two shields together (see Figure A-4) before coming to the ring terminal.
Connect a Flat Braid (item 4, Figure A-5) to the folded back shield of the prepared cable assembly. The flat braid should go out the front of the termination towards the connector. It is not permitted to exit the rear of the termination and loop back towards the connector (Figure A-5). Make this connection using an approved shield termination technique.

A.6 Daisy Chain between Methods A and B In rare situations where more braids need to be terminated for a connector than three per ring terminal and a mixture of Method A.1 Method B.1 have been used, it is allowable to daisy chain a maximum of two shields together from a Method A termination to a Method B (Figure A-7).
