This manual is not a substitute for an approved airframe-specific maintenance manual, installation design drawing, or complete installation data package. Attempting to install equipment by reference to this manual alone and without first planning or designing an installation specific to your aircraft may compromise your safety and is not recommended. The content of this manual assumes use by competent and qualified avionics engineering personnel and/or avionics installation specialists using standard aviation maintenance practices in accordance with Title 14 of the Code of Federal Regulations and other relevant accepted practices. This manual is not intended for use by individuals who do not possess the competencies and abilities set forth above. NOTE Garmin recommends installation of the G5 by a Garmin-authorized installer. To the extent allowable by law, Garmin will not be liable for damages resulting from improper or negligent installation of the G5. For questions, please contact Garmin Product Support at 1-888-606-5482. 1.2 G5 Overview The G5 is an electronic instrument display capable of operating as a standalone flight display or a fully integrated backup instrument for G3X™ systems. It features a bright, sunlight readable, 3.5-inch color display which is sized to fit in a standard 3-1/8-inch instrument cutout. With integrated attitude/ air data sensors and GPS, the G5 replaces traditional electromechanical standby instruments by combining essential information into one easy-to-read display. The G5 seamlessly integrates with other G5 units in the same aircraft and with G3X systems using the CAN network. When installed as part of a G3X system, the G5 provides a redundant source of attitude and air data to the G3X displays, and additionally provides backup autopilot control allowing coupled GPS approaches to be flown or continued in the event the primary flight display is unavailable. When installed as a standalone system, the G5 can also perform the autopilot function. In the case of aircraft power loss, the optional battery backup sustains the G5 flight display with up to 4 hours of emergency power. 190-02072-01 G5 Installation Manual Rev. 10 Page 1-2 Figure 1-1 G5 Bezel Overview 1.3 Inventory of Materials This manual provides (and provides references to) mechanical and electrical information required for the installation of the G5. This manual is intended to be a step-by-step guide to the installation, therefore it is important the steps in all sections be performed in order. All materials that are required/optional for the installation of the G5 are listed in this section (as such, some of the information in this section is repeated in following sections). Before beginning the G5 installation, it is recommended the installer perform a complete inventory of all materials listed in this section (some materials are optional and may not be applicable to the installation). Section 1 should be used to verify that all components ordered from Garmin have been delivered correctly, and to identify any required materials that are not provided by Garmin. 1.4 Unpacking the Unit Carefully unpack the equipment and make a visual inspection of all contents for evidence of damage incurred during shipment. If any component of the G5 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 any equipment to Garmin until the carrier has authorized the claim. Retain the original shipping containers for storage. If the original containers are not available, a separate cardboard container should be prepared that is large enough to accommodate sufficient packing material to prevent movement.

Use the information in Section 2 to become familiar with all aspects of the installation before actually beginning the physical installation of any equipment into the aircraft. Garmin recommends the installer become familiar with all sections of this document before beginning the installation. In general terms, the below steps are recommended to be followed in order. 1. Inventory of all needed parts 2. Planning/layout of the installation 3. Installation of LRUs, antennas, and sensors 4. Construction of wiring harness, cables, and connectors 5. Software installation/configuration 6. Post-installation checkout procedure and calibration 2.1 Electrical Considerations This section presents information required for planning the electrical layout of the G5 installation. CAUTION To avoid damage to the G5 and other LRUs, take precautions to prevent Electro-Static Discharge (ESD) when handling connectors and associated wiring. ESD damage can be prevented by touching an object that is of the same electrical potential as the LRU before handling the LRU itself. 2.1.1 Power Specifications The G5 is capable of operating at either 14 or 28 VDC. Table 2-1 lists the supply voltage and current draw information for the G5. Use this information when determining power supply requirements. All installed electrical appliances must be considered when determining total power requirements. The specified current draw listed in Table 2-1 is measured with the display backlight set to 100%. Table 2-1 G5 Power Requirements Configuration 14 V (Maximum) 14 V (Typical) 28 V (Maximum) 28 V (Typical) G5 Only 3.5 W, 0.250 Amp 2.8 W, 0.200 Amp 3.5 W, 0.125 Amp 2.8 W, 0.100 Amp G5 w/Battery 10.7 W, 0.760 Amp 2.8 W, 0.200 Amp 10.7 W, 0.380 Amp 2.8 W, 0.100 Amp 190-02072-01 G5 Installation Manual Rev. 10 Page 2-2 2.2 Wiring/Cabling Considerations Section 5 lists the pin information for the G5 and Section 7 contains interconnect drawings. It is recommended that all LRUs be installed before constructing the wiring harnesses and cables. Use MIL-W-22759/16 (or other approved wire) AWG #22 or larger wire for all non-shielded connections unless otherwise specified. Use MIL-C-27500 (or other approved wire) AWG #22 or larger wire for all shielded connections unless otherwise specified. The supplied standard pin contacts are compatible with up to AWG #20 wire. In cases where some installations have more than one LRU sharing a common circuit breaker, sizing and wire gauge is based on aircraft circuit breaker layout, length of wiring, current draw on units, and internal unit protection characteristics. RG400 or RG142 coaxial cable with 50 Ω nominal impedance and meeting applicable aviation regulations should be used when installing an optional external GPS antenna. 2.2.1 Wiring Harness Installation Use cable meeting the applicable aviation regulation for the interconnect wiring. Any cable meeting specifications is acceptable for the installation. Use the following precautions when routing cables: • All cable routing should be kept as short and as direct as possible. • Check there is ample space for the cabling and mating connectors. • Avoid sharp bends in cabling. • Avoid routing near aircraft control cables. • Avoid routing cables near heat sources, RF sources, EMI interference sources, power sources (e.g. 400 Hz generators, trim motors, etc.) or near power for fluorescent lighting. • Route the GPS antenna cable as far as possible away from all COM transceivers and other antenna cables. The installer shall supply and fabricate all of the cables. Electrical connections are made through the D subminiature connector. Section 5 defines the electrical characteristics of all input and output signals. Required connectors and associated hardware are supplied with the connector kit. Contacts for the connectors must be crimped onto the individual wires of the aircraft wiring harness. Table 1-2 lists contact part numbers (for reference) and recommended crimp tools. CAUTION Check wiring connections for errors before connecting any wiring harnesses. Incorrect wiring could cause internal component damage. 2.2.2 CAN Bus Considerations The primary digital interface used to exchange data between the G5 and other LRUs is the Controller Area Network, also known as the CAN bus. CAN was developed by Bosch GmbH in the 1980s, and its specifications are currently governed by ISO 11898-2. CAN is widely used in aviation, automotive, and industrial applications due to its simplicity and reliability. 190-02072-01 G5 Installation Manual Rev. 10 Page 2-3 2.2.3 CAN Bus Architecture The electrical architecture of the CAN bus takes the form of a linear “backbone” consisting of a single twisted wire pair with an LRU connected (terminated) at each end (Figure 2-1). The overall length of the CAN bus from end to end should be 66 feet (20 meters) or less. At each of the two extreme ends of the CAN bus, a 120 Ω resistor is installed to “terminate” the bus. Termination resistors are provided either within the LRUs themselves, or using termination adapters that plug into an LRUs CAN connection (see Section 2.2.5). Figure 2-1 CAN Bus Backbone Multiple LRU's may be connected in a daisy chain manner along the backbone of the CAN bus (Figure 2-2). Figure 2-2 CAN Bus Node Connections Daisy-chained LRUs (LRUs not at the extreme ends of the CAN bus) connect to the CAN backbone through short “stub” or “node” connections (Figure 2-3). The length of each node connection should be kept as short as possible, and should not exceed 1 foot (0.3 meter). The best way to connect devices between the ends of the CAN bus while maintaining short stub node lengths is to splice the connections as close to the device as practical. Unshielded wire sections should be kept as short as practical. Multiple devices must not connect to the CAN bus backbone at the same point. Rather than splicing two or more stub node connections together, the CAN bus should instead be daisy-chained from one device to the next (Figure 2-3). LRU LRU TERMINATION CONNECTIONS CAN BUS BACKBONE: CONSISTS OF TWISTED, SHIELDED PAIR WIRING CONNECTED TO CAN-H AND CAN-L OF EACH LRU, AND PROPERLY TERMINATED LRUs ON BOTH ENDS OF BUS.

The shields for each CAN bus wire segment should be interconnected, forming a continuously connected shield from one end of the CAN bus to the other (Figure 2-5). At a minimum, the CAN bus shield should always be grounded to the device connector backshells at the two extreme ends of the bus, but it is recommended to also ground the shield at all other devices on the CAN bus.

Connect all LRU power ground pins to a single common ground point - do not use local ground points or use the aircraft structure as a ground return path. 2.2.5 CAN Bus Termination At each of the two extreme ends of the CAN bus backbone, a 120 Ω resistor is installed to terminate the bus. Separate resistors are not required, termination resistors are provided either within the LRUs themselves, or using termination adapters that plug into an LRU’s CAN connection. • The GAD 13, GAD 29, GMU 11, GPS 20A, and G5 installation kits each provide a 9-pin termination adapter that provides CAN bus termination when attached between the LRU and the cable assembly. The termination adapter contains a 120 Ω resistor that is connected between pins 1 and 2 (Figure 2-6). • The GMC 507 and GSA 28 contain a 120 Ω resistor inside the unit that provides termination when the two CAN-TERM pins are connected together (Figure 2-7).

This adapter can be used when a GSA 28 is removed from the aircraft. The removal adapter keeps the node on the CAN bus in the same state as when the servo was installed (either terminated or un-terminated). The removal adapter also allows trim signals to pass through when no servo is installed. 2.2.7 CAN Bus Installation Guidelines For maximum reliability of the CAN bus, the following guidelines should be followed: • The CAN bus backbone must be a single linear path with exactly two distinct ends. CAN bus connections should be daisy-chained from device to device. Avoid “T”, “Y”, and "star" topologies, and do not use a hub device (Figure 2-4). • The overall length of the bus should not exceed 66 feet (20 meters). • Keep all stub node connections as short as practical. The maximum length of any stub node connection is 1 foot (0.3 meter). • Avoid connecting more than one device to the CAN bus backbone at the same point. Instead, daisy chain the CAN bus backbone from one device to the next. • Follow proper wiring, shielding, and grounding requirements described in Section 2.2.2. • Terminate the CAN bus at the two extreme ends of the bus, as described in Section 2.2.3. • When adding a new device to the CAN bus, evaluate proposed modifications to the CAN bus wiring connections to ensure compliance with all of the preceding requirements. 2.2.8 CAN Bus Troubleshooting The CAN bus is very simple, and a properly installed CAN bus is very reliable. If problems are occurring, the following steps can help to identify the issue. 1. Review the status LED of devices on the CAN bus such as the GSA 28 servos. The status LED indications are listed in Table 2-2. 2. Make sure the CAN bus is daisy-chained between CAN devices around the system, and that CAN devices are not connected using a single point (star topology) or routed through a hub device. This Table 2-2 Status LED Indications LED Indication Description No Light No power Steady Green On but not communicating through CAN bus Flashing Green On and communicating through CAN bus Red Hardware fault Alternating Red/Green CAN bus network error (two identical LRUs are configured with the same unit ID) 190-02072-01 G5 Installation Manual Rev. 10 Page 2-8 can cause unwanted signal reflections and “orphan” some devices on the bus and prevent their communication. 3. Make sure the CAN bus is terminated in only two locations, and only at the extreme ends of the CAN bus. 4. With power removed, remove the CAN bus connector from one of the devices that is not located at either of the extreme ends of the CAN bus. a) Using an ohm meter, verify the resistance between the CAN-H and CAN-L pins on the con- nector is 60 Ω. This will verify the CAN backbone is properly terminated at each end (two 120 Ω terminating resistors in parallel). b) A resistance of 120 Ω indicates that one of the two required CAN terminations is missing. c) A resistance of 40 Ω or less indicates that too many terminations are installed. 5. Verify the CAN-H and CAN-L signals are not swapped, shorted together, or open-circuited at any LRU connector. 6. Verify the CAN-H and CAN-L signals are not shorted to ground (this can happen when shielded wire is installed incorrectly). 7. Highlight each device on the configuration mode Device Information page and verify the value displayed for Network Error Rate is a steady 0%. Figure 2-10 Network Error Rate 8. Start only the #1 G5 unit and one other CAN device at a time, and verify the connection quality for each device. Sometimes a device will communicate only when it is the only powered device on the CAN bus, if one or more of the above issues is present. Evaluating each CAN device in turn can help narrow down a problem. 9. It is very important for each device on the CAN bus to share a common power/signal ground. Ground potential differences between devices on the CAN bus can cause communication errors. Ground devices to a common ground bus, not to the airframe or to multiple grounding buses. 190-02072-01 G5 Installation Manual Rev. 10 Page 2-9 10. Advanced CAN diagnostics are available by selecting Device Information, Diagnostics, CAN Network. Any increase of these parameters above zero is an indication of a CAN bus issue. Figure 2-11 CAN Diagnostic Page 2.2.9 Cable Connector Installation A coaxial cable connection is required for the optional external GPS antenna. 1. Route the coaxial cable to the unit location. Secure the cable in accordance with good aviation practices. 2. Trim the coaxial cable to the desired length and install the BNC connector. If provided, follow the connector manufacturer’s instructions for cable preparation. 190-02072-01 G5 Installation Manual Rev. 10 Page 2-10 2.3 Mechanical Considerations This section presents all information required for planning the physical layout of the G5 installation. 2.3.1 Physical Specifications Table 2-3 lists panel requirements. All width, height, and depth measurements are taken with unit mounting ring and connectors (if applicable). 2.3.2 Cooling Requirements While no forced cooling air is required for the G5, it is highly recommended the air behind the panel be kept moving (by ventilation or a fan). Units tightly packed in the avionics stack heat each other through radiation, convection, and sometimes by direct conduction. Even a single unit operates at a much higher temperature in still air than in moving air. Fans or some other means of moving the air around electronic equipment are usually a worthwhile investment. NOTE Avoid installing LRUs near heat sources. If this is not possible, ensure that additional cooling is provided. Allow adequate space for installation of cables and connectors. The installer will supply and fabricate all of the cables. All wiring should be in accordance with FAA AC 43.13-1B and AC 43.13-2B. 2.3.3 Compass Safe Distance After reconfiguring the avionics in the cockpit panel, if the unit is mounted less than 12 inches from the compass, recalibrate the compass and make the necessary changes for noting correction data.

See Figure 7-3 for LPM Wiring Interface 190-02072-01 G5 Installation Manual Rev. 10 Page 3-3 3.3.2 Additional Equipment Required A 3/32” hex drive tool is required to secure the G5 to the panel as described in Section 3.6.3 and shown in Figure 3-4. Air hoses and fittings are required to connect pitot air and static air to the G5. The G5 uses a female 1/8-27 ANPT fitting for each of these ports. Use appropriate aircraft fittings to connect to pitot and static system lines. 3.4 Unit Installation Fabrication of a wiring harness is required. Sound mechanical and electrical methods and practices are recommended for installation of the G5. Refer to Section 2.2 for wiring considerations, and to Section 5 for pinouts. Connector kits include backshell assemblies. Garmin’s backshell connectors give the installer the ability to quickly and easily terminate shield grounds at the backshell housing. Instructions needed to install the Jackscrew Backshell and Shield Block Ground can be found in Section 6. 3.4.1 Mounting Requirements The G5 includes an extremely sensitive inertial measurement unit. Consider the following when selecting a mounting location: • Mount the G5 with the connector aligned to within 15.0° of the longitudinal axis of the aircraft (display bezel parallel to the wing spar). Configuration allows for direct manual entry of the present yaw offset when the instrument panel to which the G5 is mounted is not perpendicular to the aircraft centerline. • The G5 should be rigidly mounted to the aircraft panel. To avoid degraded accuracy, the aircraft panel should be rigid and panel flexing should be minimized. • The G5 should be mounted to the aircraft panel with the connector facing toward the front of the aircraft. • The G5 should be mounted within 13 feet (4 meters) longitudinally of the aircraft CG (center of gravity). In cases where the longitudinal distance from the CG is planned to be greater than 6.5 feet (2 meters), it is preferable to mount the G5 forward of the aircraft CG, if possible, to improve autopilot performance. • To prevent degraded accuracy, avoid placing the G5 near areas that are prone to severe vibration. • The G5 must be leveled to within 30.0° of the flight level cruise attitude. An aircraft leveling and offset calibration procedure must additionally be carried out before flight. • The mounting location for the G5 should be protected from rapid thermal transients, in particular large heat loads from nearby high-power equipment. • Avoid placing the G5 within 1 inch of magnetically mounted antennas, speaker magnets, or other strongly magnetic items. 3.4.2 Unit Mounting For final installation and assembly, refer to the outline and installation drawings in Section 3.7. 1. Mount the G5 in a suitable location using the installation kit (Table 3-1) per the requirements in Section 3.4.1. 2. Assemble the wiring harness and backshell connector. 3. Assemble the pneumatic hoses and connector. 4. Connect the CAN terminator if required (see Section 2.2.5). 5. Connect the backshell connector and hoses. 190-02072-01 G5 Installation Manual Rev. 10 Page 3-4 3.4.3 Pneumatic Plumbing The G5 has two ports that are connected to the aircraft’s pitot and static pressure sources. The ports are labeled on the unit using the abbreviations “P” and “S” respectively (Figure 3-1). The pressure ports have 1/8-27 ANPT female threads. The mating fitting must have 1/8-27 ANPT male threads. NOTE The temporary port plugs attached to the pressure ports on a new G5 are not suitable for flight and must be removed before the installation of the G5 into the aircraft. NOTE In an installation with dual G5 units, pitot/static plumbing must be connected to both units. Figure 3-1 G5 Air Hose Fitting Locations Use appropriate air hoses and fittings to connect the pitot and static lines to the unit. Avoid sharp bends in the tubing and attempt to route hoses away from aircraft control cables. The G5 should not be at the low point of the pneumatic plumbing lines to avoid moisture or debris collecting at or near the unit. Ensure that no deformations of the airframe surface have been made that would affect the relationship between static air pressure and true ambient static air pressure for any flight condition. Refer to CFR Part 43, Appendix E for approved practices while installing hoses and connections. NOTE A G5 installed as a standalone unit may optionally be configured to disable its internal air data sensors. In this case, no connection to the aircraft's pitot/static system is required. If not connected, the pitot/static fittings on the G5 should be covered with dust caps. A G5 with air data disabled does not support autopilot functionality. 190-02072-01 G5 Installation Manual Rev. 10 Page 3-5 3.4.4 Pneumatic Connections The following steps should be used to aid in the fabrication of pneumatic hose connections and in attaching the aircraft pitot pressure source and aircraft static pressure sources to the G5. NOTE Whenever the aircraft is connected to a pitot-static tester, such as during Part 43 Appendix E altimeter tests, the pitot port must be covered by a pitot adapter that is controlled by the pitot- static tester. Failure to do so will result in overpressuring and damaging the internal airspeed sensor. NOTE Use of different colored tubing is recommended for static and pitot plumbing to avoid plumbing connection errors. Incorrect plumbing connections will result in erroneous air data information calculated by the G5. Follow these cautions when connecting pneumatic lines: 1. Make sure the aircraft static pressure port is plumbed directly to the unit static pressure input port and the aircraft pitot pressure port is plumbed directly to the unit pitot pressure input port. 2. Seal the threads of pneumatic fittings at the connector ports. Use caution to ensure there are no pneumatic leaks. 3. Use care to avoid getting fluids or particles anywhere within the pneumatic lines connected to the G5. 3.5 Antennas Refer to Section 4 for antenna installation information. 190-02072-01 G5 Installation Manual Rev. 10 Page 3-6 3.6 Mounting Instructions Refer to Section 3.7 for outline and installation drawings. NOTE In addition to the mounting requirements listed in Section 3.4.1, it is critical the G5 be installed with its display bezel perpendicular to the aircraft's longitudinal axis (display bezel parallel to the wing spar) and as close to level in the roll axis as possible. Small roll offsets, and pitch offsets up to 30°, can be corrected for during calibration. 3.6.1 Panel Cutout Template The G5 Mounting Ring (115-02251-03) or Figure 3-10 can be used as a template when marking the panel for cutout. See Figure 3-9 for complete cutout dimensions (the dimensions on Figure 3-9 are to verify the accuracy of the printout only). 3.6.2 Mounting Ring Installation Secure the mounting ring to the aircraft panel using the supplied #6-32 pan head Phillips mounting screws. Evenly torque the mounting screws to 10-12 in-lb.

For installations with a panel thickness greater than 0.150 inch, the captive mounting screw can be replaced with a standard #6-32 hex socket head screw. To replace the screw, remove the two #4-40 flat head Phillips mount plate screws, the G5 screw mount plate, and the captive screw as shown in Figure 3-5. Reverse this process to install the longer #6-32 hex socket head screw. Ensure correct orientation of the screw mount plate before applying 6-8 in-lb of torque to the #4-40 mount plate screws. NOTE Standard #6-32 hex socket head screws use a 7/64” hex drive feature. The access hole in the G5 bezel is large enough to accommodate this increase in hex tool size.

Garmin recommends the antennas shown in Table 4-2. However, any equivalent antenna that meets the specifications listed in Table 4-3 will work with the G5. The G5 can receive GPS position information using the unit's internal antenna or by connecting an external antenna. It is recommended to verify the ability of the G5 to receive GPS information from the unit's internal antenna as GPS reception quality is dependent upon the installation (see Section 8.4.13.1 GPS Reception). The G5 will share GPS information with any connected GDU™ 37X/4XX. The G5 can additionally receive GPS position information from a GPS 20A or GDU 37X/4XX. A minimum of one GPS antenna is required for G5 installations receiving GPS information from another LRU. Additional GPS antennas may be used for redundancy, but are not required. A GPS 20A (and connected GPS/WAAS antenna) can be used as the sole GPS source for a G5 system, however it is recommended to also install a GPS antenna on a G5 or GDU 37X/4XX for redundancy. If the G5's GPS receiver is not used in a particular installation, it may be disabled in configuration mode (see Section 8.4.13). 4.1 Non-Garmin Antennas Table 4-1 lists non-Garmin antennas currently supported by the G5. For non-Garmin antennas, follow the manufacturer’s installation instructions. It is the installer’s responsibility to ensure the chosen antenna meets FAA standards according to the specific installation. 4.2 Garmin Antennas NOTE See the G3X™/G3X Touch™ Installation Manual (190-01115-01) for detailed GPS antenna installation information. All antenna mounting and unit installation recommendations applicable to the GDU37X/4XX also apply to the G5. NOTE It is the installer’s responsibility to ensure the chosen antenna meets FAA standards according to the specific installation.

At one end of a shielded cable (item 2, Figure 6-1 or Figure 6-2) measure a distance between Window Min and Window Max (Table 6-5) and cut a window (with a max size of 0.35 inch) in the jacket to expose the shield. Use caution when cutting the jacket to avoid damaging the individual braids of the shield. When dealing with a densely populated connector with many cables, it may prove beneficial to stagger the windows throughout the Window Min to Window Max range. If staggering is not needed, the Ideal Window length is recommended. The following tools are recommended to make the window cut: • Coaxial Cable Stripper • Thermal Stripper • Sharp Razor Blade 2. Connect a flat braid (item 4, Figure 6-3) to the shield exposed through the window of the prepared cable assembly from the preceding step. The flat braid should exit the front of the termination and towards the connector. The flat braid should not exit the rear of the termination and loop back towards the connector. Make the connection between the flat braid and the prepared cable assembly using an approved shield termination technique. NOTE FAA AC 43.13-1B Chapter 11, Section 8 (Wiring Installation Inspection Requirements) may be a helpful reference for termination techniques.

Using a solder sleeve with a pre-installed flat braid may ease the assembly. The chosen size of solder sleeve must accommodate both the number of conductors present in the cable and the flat braid. Solder sleeves with pre-installed flat braid The preferred solder sleeve is the Raychem S03 Series with a thermochromic temperature indicator (S03-02-R-9035-100, S03-03-R-9035-100, S03-04-R-9035-100). These solder sleeves come with a pre-installed braid and effectively take the place of items 3 and 4 in Figure 6-3. Reference the Raychem installation procedure, RCPS 100-70, for detailed instructions. Raychem recommends the following heating tools: • HL1802E • AA-400 Super Heater • CV-1981 • MiniRay • IR-1759 Individual solder sleeves and flat braid Solder Sleeves: Reference the following MIL-SPECs for solder sleeves: • M83519/1-1 • M83519/1-2 • M83519/1-3 • M83519/1-4 • M83519/1-5 Flat Braid: Flat braids should conform to the ASTMB33 standard for tin-plated copper wire and be made up of 36 AWG strands to form an approximately 19-20 AWG equivalent flat braid. A circular mil area range of 1000 to 1300 is required. The number of individual strands in each braid bundle is not specified. Reference MIL-SPEC flat braid QQB575F36T062. NOTE Flat braid, as opposed to insulated wire, is specified in order to allow for a visual inspection of the conductor as required for continued airworthiness. Secondary Method: Solder a flat braid 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 conductor(s) and shorts the shield to the signal wire(s). Slide a minimum of 0.75 inch of Teflon heat shrink tubing (item 3, Figure 6-3) onto the prepared wire assembly and shrink using a heat gun. The chosen size of heat shrink tubing must accommodate both the number of conductors present in the cable and the flat braid. Teflon heat shrink tubing Reference MIL-SPEC Teflon heat shrink tubing M23053/5-X-Y. 190-02072-01 G5 Installation Manual Rev. 10 Page 6-7 3. At the same end of the shielded cable and ahead of the previous shield termination, strip back the jacket and shield from the end of the shielded cable to a distance between Float Min and Float Max (Table 6-5) to expose the insulated center conductor(s). If possible, the Ideal Float length is recommended. Preferred Method: Cut the jacket and the shield off at the same point so that no shield is exposed. Slide a minimum of 0.75 inch of Teflon heat shrink tubing (item 5, Figure 6-3) onto the cable and use a heat gun to shrink the tubing. The chosen size of heat shrink tubing must accommodate the number of conductors present in the cable. Secondary Method: Leave a maximum 0.35 inch of shield extending past the jacket. Fold this section of shield back over the jacket. Slide a solder sleeve (item 5, Figure 6-3) over the end of the cable and use a heat gun approved for solder sleeves to secure the connection. The chosen size of solder sleeve must accommodate the number of conductors present in the cable. 4. Strip back approximately 0.17 inch of insulation from each wire of the shielded cable (item 2, Figure 6-4) and crimp a contact (item 6, Figure 6-4) to each conductor. It is the responsibility of the installer to find the proper length of insulation to be removed. The wire must be visible in the inspection hole after crimping and the insulation must be 1/64 – 1/32 of an inch from the end of the contact as shown in Figure 6-4. Figure 6-4 Insulation/Contact Clearance 6 2 190-02072-01 G5 Installation Manual Rev. 10 Page 6-8 5. Insert the newly crimped pins and wires into the appropriate connector housing location as specified by the installation wiring diagrams. 6. Cut the flat braid to a length that, with the addition of a ring terminal, will reach one of the tapped holes of the Jackscrew Backshell (item 1, Figure 6-1 or Figure 6-2). An appropriate amount of excess length without looping should be given to the flat braid to allow it to freely move with the wire bundle. NOTE The window splice should be positioned so the flat braid is no longer than 4 inches. 7. Guidelines for terminating the flat braid with an insulated ring terminal: • Each tapped hole on the Jackscrew Backshell may accommodate a maximum of two ring terminals. • Each ring terminal may accommodate a maximum of three flat braids. However, it is recommended to terminate a maximum of two flat braids per ring terminal. • A #8, insulated, 18-22 AWG ring terminal is recommended for terminating a single flat braid (reference MIL-SPEC MS25036-149). • A #8, insulated, 14-16 AWG ring terminal is recommended for terminating two flat braids (reference MIL-SPEC MS25036-153). • A #8, insulated, 10-12 AWG ring terminal is recommended for terminating three flat braids (reference MIL-SPEC MS25036-156). 8. Repeat the preceding steps as necessary for the remaining shielded cables. 9. Terminate the ring terminal to the Jackscrew Backshell by placing the following items on the screw (item 8, Figure 6-1 or Figure 6-2) in order: split washer (item 9, Figure 6-1 or Figure 6-2), flat washer (item 10, Figure 6-1 or Figure 6-2), ring terminal (item 7, Figure 6-1 or Figure 6-2). This assembly can then be screwed into the tapped holes on the Jackscrew Backshell. 10. It is recommended to wrap the cable bundle with silicone fusion tape (item 11, Figure 6-1 or Figure 6-2) at the point where the backshell clamp (item 12, Figure 6-1 or Figure 6-2) and backshell housing will contact the cable bundle. NOTE Use of silicone fusion tape is at the discretion of the installer. 11. Place the smooth side of the backshell clamp across the cable bundle and secure using the provided screws (item 13, Figure 6-1 or Figure 6-2). WARNING Placing the grooved side of the backshell clamp across the cable bundle may cause damage to the wires. 12. Attach the backshell cover (item 14, Figure 6-1 or Figure 6-2) to the backshell using the provided screws (item 15, Figure 6-1 or Figure 6-2). 190-02072-01 G5 Installation Manual Rev. 10 Page 6-9 6.4 Shield Termination Technique – Method A.2 (Daisy Chain) In rare situations where more flat 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 before terminating to the ring terminal (Figure 6-5). All other restrictions and instructions for the shield termination set forth in Method A.1 are still applicable. NOTE The maximum length of the combined braids should be 4 inches. Figure 6-5 Shield Termination Technique Method A.2 190-02072-01 G5 Installation Manual Rev. 10 Page 6-10 6.5 Shield Termination Technique – Method B.1 (Quick Term) If desired, the drain wire termination (item 3, Figure 6-1 or Figure 6-2) and the floating shield termination (item 5, Figure 6-1) can be effectively combined into a “Quick Term”. This method eliminates the float in the cable insulation and moves the placement of the window described in Method A.1. This technique is depicted in Figure 6-6. NOTE The original purpose for separating the shield drain termination from the float termination in Method A.1 was to allow for a variety of lengths for the drain wires so the shield drain terminations would not all bunch up in the harness and to eliminate loops in the drain wires. If Method B.1 is used, care must be taken to ensure that all drain shield terminations can still be inspected. Garmin recommends using Method A.1 on connectors which require a large number of shield drain terminations, as this will allow these terminations to be dispersed across a larger area. Figure 6-6 Shield Termination Technique Method B.1 1. At one end of a shielded cable (item 2, Figure 6-1 or Figure 6-2) measure a distance between Window Min and Window Max (Table 6-6) and cut a window (with a max size of 0.35 inch) in the jacket to expose the shield. Use caution when cutting the jacket to avoid damaging the individual braids of the shield. When dealing with a densely populated connector with many cables, it may prove beneficial to stagger the windows throughout the Window Min to Window Max range.

The following tools are recommended to make the window cut: • Coaxial Cable Stripper • Thermal Stripper • Sharp Razor Blade 190-02072-01 G5 Installation Manual Rev. 10 Page 6-11 2. Strip back the jacket from the end of the shielded cable to a distance between Quick Term Min and Quick Term Max (Table 6-5) to expose the shield. Next trim the shield so that a maximum of 0.35 inch of shield extends beyond the jacket. Fold this section of shield back over the jacket. 3. Connect a flat braid (item 4, Figure 6-6) to the folded back shield of the prepared cable assembly. The flat braid should exit the front of the termination and towards the connector. The flat braid should not exit the rear of the termination and loop back towards the connector. Make the connection between the flat braid and the prepared cable assembly using an approved shield termination technique. NOTE FAA AC 43.13-1B Chapter 11, Section 8 (Wiring Installation Inspection Requirements) may be a helpful reference for termination techniques.

All other restrictions and instructions for the shield termination set forth in Method A.1 and B.1 are still applicable. NOTE The maximum length of the combined braids should be 4 inches. Figure 6-8 Shield Termination Technique Methods A.1 and B.1 190-02072-01 G5 Installation Manual Rev. 10 Page 6-15 6.8 Unit ID (Strapping) The Unit ID Program Pin on the G5 provides a ground reference used by the hardware as a means of configuring the unit for system identification. When installing two G5 units, the second unit must have its UNIT ID pin (J51 pin 3) connected to ground. For the first G5, this pin should be left unconnected. The following instructions illustrate how this ground strapping should be accomplished with the Jackscrew Backshell. 1. Cut a 4-inch length of 22 AWG insulated wire. WARNING Flat braid is not permitted for this purpose. Use only insulated wire to avoid inadvertent ground issues that can occur when using exposed conductors. 2. Strip back approximately 0.17 inch of insulation and crimp a contact to the 4-inch length of wire. It is the responsibility of the installer to find the proper length of insulation to be removed. The wire must be visible in the inspection hole after crimping and the insulation must be 1/64 – 1/32 of an inch from the end of the contact as shown in Figure 6-4. 3. Insert the crimped pin and wire into the appropriate connector housing location as specified by the installation wiring diagrams. 4. At the opposite end of the wire, strip back 0.2 inch of insulation. 5. Terminate this end of the wire in conjunction with the flat braids of the shield terminations. If this ground strap is the only termination, use a #8, insulated, 18-22 AWG ring terminal for the termination (reference MIL-SPEC MS25036-149). 190-02072-01 G5 Installation Manual Rev. 10 Page 6-16 6.9 Splicing Signal Wires Figure 6-9 shows an example two wire splice. Note the splice must be made within 3 inches of the Shield Block. A signal wire should be spliced into a maximum of three wires. This wire splicing technique can be used with all the shield termination methods outlined in the previous sections. The following wire splice parts are recommended: • Raychem D-436-36/37/38 • MIL-SPEC MIL-S-81824/1 WARNING Keep the splice out of the backshell for pin extraction, and outside of the strain relief to avoid preloading.
