11 2 Electrical Installation Procedure 2.1 Special Tools Required A crimp tool meeting MIL specification M22520/2-01 and a positioner/locator are required to ensure consistent, reliable crimp contact connections for the rear D-sub connectors. Refer to Table 2-1 for a list of recommended crimp tools. Hand Table 2-1. Recommended Crimp Tools AWG [3] AWG Manufacturer Crimping Insertion/ Insertion/ Tool Positioner Positioner Extract Tool Extract Tool Military P/N M22520/2-01 M22520/2-08 M81969/14-02 M81969/1-02 M22520/2-09 M81969/14-01 M81969/1-04 Positronic N/A M81969/1-04 ITT Cannon N/A N/A N/A AMP N/A N/A Daniels AFM8 K13-1 N/A K42 N/A Astro N/A N/A Notes: [1] Contacts listed are not to be used for configuration module wiring. Use the contacts supplied with the configuration module when installing configuration module wires. [2] Non-Garmin part numbers shown are not maintained by Garmin and are subject to change without notice. [3] For configuration module pins, ensure that the crimp tool is set to crimp 28 AWG wire (indenter setting of 4 ). 2.2 Power Distribution Circuit protection devices for the GTS 8XX must be push-pull manually resettable circuit breakers (e.g. Klixon 7274 or 7277 series circuit breakers. A single circuit breaker must be dedicated to the GTS 8XX. Do not attempt to combine more than one unit on the same circuit breaker, unless specifically approved by the manufacturer. The GTS 8XX should be connected to an avionics bus (non-essential bus) so that power will be supplied to the GTS 8XX when the avionics master switch is turned on. 2.3 Electrical Load Analysis An electrical load analysis should be completed on each aircraft prior to installation in accordance with AC B, Chapter 11 and recorded on FAA Form 337. Use the following values for computation: LRU 14 Volt Current Draw 28 Volt Current Draw Typical Maximum Typical Maximum GTS ± 0.2 A 2.6 A 1.1 ±0.2 A 1.5 A GTS 820/ ± 0.3 A 3.2 A 1.3 ± 0.2 A 1.6 A NOTE Circuits should be protected in accordance with the approved data in this document (see Appendix C for recommended GTS 8XX LRU circuit breaker ratings) and the guidelines in AC B, Chapter 11, Section 4. Page 2-1 Rev

12 2.4 Cabling and Wiring Use #24 AWG or larger diameter wire for all connections unless otherwise specified. The minimum diameter wire size for all GTS 8XX installation wiring is #24 AWG, except in the case of Aircraft Power and Aircraft Ground and both shall be a minimum of #18 AWG. Refer to Table 2-2 for more information Electrical Bonding Electrical equipment, antennas, supporting brackets, and racks must be electrically bonded to the aircraft s main structure. Refer to SAE ARP 1870 section 5 when surface preparation is required to achieve electrical bond. The electrical bond should achieve direct current (DC) resistance less than or equal to 2.5 milliohms to local structure to where the equipment is mounted. Compliance should be verified by inspection using a calibrated milliohm meter. An equivalent OEM procedure may also be substituted. The antenna ground plane must be electrically bonded to the antenna baseplate. The electrical bond must achieve direct current (DC) resistance less than or equal to 2.5 milliohms. Do not remove paint on outer skin of aircraft under the footprint of the antenna baseplate unless necessary to meet bonding requirements. The painted surface prevents corrosion and should be left intact if possible. The resistance of 2.5 milliohms can be achieved through the mounting screws which are attached to the antenna doubler Shield Termination Considerations Shield termination at non-garmin equipment end must be as short as possible taking into consideration any non-garmin equipment s installation requirements. The shields may be connected to the metal connector backshell when the backshell is grounded to airframe chassis ground or the shield termination may be directly connected to airframe chassis ground. While the interconnects in Appendix C do not show intermediate connectors, all shields must have continuity at any intermediate connectors used unless otherwise specified. When shields are terminated to the aircraft ground or metal backshell to provide this continuity, the shield drain wire must be no longer than 3 inches, unless non-garmin equipment requires shorter length. The termination method from section may be used at these locations unless this conflicts with the requirement of Non-Garmin equipment. If intermediate connectors are used on an audio line, either run the shields through a pin on all intermediate connectors or terminate shield drain wires at the intermediate connector if they are grounded to airframe. The shields between any two connectors must only be grounded at one end to prevent ground loops. The shield must be terminated to ground at the GTS 8XX. If a connector at the opposite end from the GTS 8XX has overbraid then any wires from this connector to the GTS 8XX must also be overbraided. The overbraid must be terminated as close to the connector as possible taking into account any requirements imposed by the non-garmin equipment. These additional wires must be separately overbraided and ensure they are routed with the existing cable where possible Switch Selection and Location Depending on display capabilities, switches may be required as part of the installation to control the GTS 8XX. A standby/operate switch as well as a self test initialize switch are required if the chosen traffic display does not include provisions for control of this functionality. Refer to the appropriate drawing in Appendix C for switch selection and labeling. Both the Standby/Operate switch and the Self Test select switch must be mounted adjacent to the traffic display easily accessible to the pilot. Both switches must be mounted within the acceptable field of view of the pilot. Acceptable field of view is defined as 35 degrees left and right from the centerline of the control yoke in the pilot s normal seated position and 25 degrees vertically up and 35 degrees vertically down from horizontal. Page Rev. 2

13 The Traffic Advisory Acknowledge switch is used to mute TA audio. It should be mounted adjacent to the traffic display fully accessible to the pilot. This switch can also be mounted on top of the pilot s control yoke. The TA acknowledge switch location must not interfere with other switches or controls on the yoke GPA 65 Cable and Wiring Requirements The GTS 800 requires two sets of coaxial cable assemblies and the GTS 820/850 requires three sets of coaxial cable assemblies when a directional GA 58 antenna (or other Garmin approved antenna) is used for both top and bottom. Each set consists of four coaxial cable assemblies. Each set of four cables must be assembled using the same type of coaxial cable in order to meet phase and attenuation matching requirements. In order for the system to operate in compliance with manufacturer specifications, the coaxial cable assemblies must not exceed the attenuation specifications as stated in this section. If an optional low-profile antenna is installed, TNC connectors (not provided) must be installed on the antenna end of the coaxial cables. Note that due to the cable loss requirements, the GPA 65 needs to be mounted in close proximity to the TAS/TCAS antenna. Refer to Table 2-4 for the maximum cable lengths for the selected coaxial cable. Note that the GPA 65 circular connector kit ( ) comes with a bulkhead connector. It is not necessary to ground the bulkhead connector flange to aircraft ground. NOTE The maximum wiring length from the GTS 8XX to the GPA 65 is 45 feet. Refer to Table 2-2 below for further information. Table 2-2.

21 Coaxial Cable Assembly Instructions The following assembly instructions apply to coaxial cable assemblies using QMA connectors specified in Table 2-3 for use with RG-400 or RG-142 cable types: 1. Slide the heat shrink sleeve and crimp ferrule onto the cable. 2. Strip the cable to the dimensions shown in Figure 2-7. Figure 2-7. RG-400/RG-142 Coaxial Cable Stripping Dimensions 3. Slide the center contact onto the center conductor of the cable. Ensure the center conductor of the cable is visible through the inspection hole of the center contact and crimp using Tyco Tool and die assembly , or Tyco Tool and die assembly , or Tyco Tool Expand the shielding braid and insert the crimped center contact into the connector body until the cable dielectric is flush with the dielectric inside the connector body. Ensure the shield braid does not enter the connector body. Ferrule to be flush with Connector Body back end Connector Body Ferrule Coaxial Cable Ferrule Crimp Bellmouth Crimp Die Figure 2-8. Ferrule and Crimp Die Positioning Page 2-11 Rev

22 5. Slide the crimp ferrule over the shielding braid to the back of the connector body. Position the crimp tool flush with the back of the connector body and crimp using Tyco tool and die assembly , or Tyco tool and die assembly , or Tyco tool The crimp tool should be positioned such that a bellmouth (see Figure 2-8) is present in the crimp ferrule on the coaxial cable side of the crimp after crimping. 6. Slide heat shrink sleeve to back of connector body and shrink in place. Ensure that the heat shrink does not protrude past the connector body back end once it is shrunk into place. It is recommended that the color-coded heat shrink tubing provided in the kit be used. Place the colorcoded band on the coaxial cable near the connector body and shrink in place. Connector Body Ferrule Coaxial Cable Heat shrink not to protrude past This surface Figure 2-9. Heat Shrink Positioning NOTE Use of QMA connectors other than those specified in Table 2-2 for coaxial cable assemblies fabricated by the installing agency using either M17/128-RG400 or M17/60-RG142 coaxial cable will constitute the cable assemblies as being non-compliant with the GTS AML STC Coaxial Cable Assembly Repair and Rework In the event that an individual coaxial cable assembly requires rework, the following rules apply: Top or bottom GTS 800 to GA 58 (or other Garmin approved antenna) cables may be repaired with a reduction in length of 2 maximum. Top or bottom GTS 820/850 to GPA 65 cables may be repaired with a reduction in length of 2 maximum. GPA 65 to GA 58 (or other Garmin approved antenna) cables (on GTS 820/850 systems only) must be replaced if repair is required because connector replacement would cause the matched cable length requirement of 0.25 to be exceeded. Refer to Table 2-3 for recommended maximum cable assembly lengths for cable assemblies fabricated by the installer. NOTE If rework of a coaxial cable assembly is required, the reworked cable length must still meet the length tolerance requirements specified in Table 2-5. Page Rev. 2

23 2.4.6 Wiring Harness Allow adequate space for installation of cables and connectors. The installer supplies and fabricates all of the cables. Construct the wiring harness according to the information contained in this and the following sections. Cable lengths will vary depending upon installation. Strip all wires going to the connectors Insert the wire into the pin and crimp with one of the recommended (or equivalent) crimping tools. Insert the pin into the connector housing location as specified by the interconnect drawing in Appendix B. Verify that the pin is properly engaged into the connector by gently tugging on the wire. Route and secure the cable runs from the GTS 8XX away from sources of electrical noise. Appendix B provides the pinout information for the GTS 8XX. Required connectors and associated hardware are supplied with the connector kits. See Appendix C for interconnect wiring diagrams. CAUTION Check wiring connections for errors before connecting the cables to the LRUs. Incorrect wiring could cause component damage. Manufacturer Table 2-6.

25 Notes: 1. Non-Garmin part numbers shown are not maintained by Garmin and consequently are subject to change without notice. 2. Extracting a contact used for #18 AWG requires that the wire barrel be cut off from the contact. It may also be necessary to push the pin out from the face of the connector when using an extractor due to the absence of the wire. A new contact must be used when reassembling the connector. 3. Contacts for #16 AWG and Contact Crimp Tooling: Contact Garmin for information regarding contacts and contact crimp tooling. Note 2 also applies. 4. Alternate Contacts for Use With #18 AWG: As an alternative to the Positronic contacts listed, and provided in the installation kit, if the need arises the installer may use contacts made by ITT Cannon under P/N The particular contact is not compatible with the Daniels MFG K774, Positronics or Amphenol positioners. Only use postioner part numbers Daniels MFG K250, ITT Cannon and Astro QMA Connector Insertion and Removal To engage the QMA connectors, use the outer sleeve of the QMA plug to align the connectors and insert the plug into the jack until it snaps into place. There will be an audible snap when the connectors are fully engaged. Refer to the figure below. No tools are required for the insertion of a QMA plug onto a QMA jack. Engage Outer Sleeve Figure Engaging QMA Connectors To disengage the QMA connectors, pull back firmly on the outer sleeve of the QMA plug away from the jack connector (refer to the figure below.) This will disengage the locking mechanism that secures the plug connector to the jack connector. Pulling on or disengaging the QMA connectors in any other way is not recommended and may cause damage to both the connectors and coaxial cable. CAUTION Do not pull on the cable when removing the QMA plug from the jack. Page 2-15 Rev

26 Figure Disengaging QMA Connectors CAUTION Side-loading of the QMA connectors should be avoided during both the insertion and removal of the connectors. It is recommended that service loops with adequate length of coaxial cable be used to insure that side-loading on the connectors is minimized once the cable is securely fastened in the aircraft. Excessive side-loading may result in damage or premature failure of the QMA connectors. Page Rev. 2

27 2.4.8 Backshell Assembly and D-Subminiature Connectors The GTS 8XX connector kits include three Garmin backshell assemblies. The backshell assembly houses the configuration module. Garmin s backshell also gives the installer the ability to easily terminate shield grounds at the backshell housing. Refer to section for configuration module assembly instructions. List of Parts: Table 2-11 provides a list of parts needed to install a Jackscrew Backshell. Parts for this installation are included in the Jackscrew Backshell installation kits along with other Garmin installation kits, and some are to be provided by the installer.

30 Backshell Assembly Procedure NOTE For the following steps please refer to Figure (Figure references are in parenthesis) 1. The appropriate number of Jackscrew Backshells will be included in the particular LRU connector kit. Table Shielded Cable Preparations for Garmin Connectors Backshell Size Number of Pins Std/HD Float Min (inches) Float Max (inches) Ideal Float (inches) Window Min (inches) Window Max (inches) Ideal Window (inches) 4 37/ / At one end of a shielded cable (2) measure a distance between Window Min to Window Max and cut a window (max size 0.35 ) in the jacket to expose the shield as shown in Figure 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. NOTE The window cut should be accomplished with either coaxial cable strippers, thermal strippers, or a sharp razor blade. 3. Connect a Flat Braid (4) to the shield exposed through the window of the prepared cable assembly (2) 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 2-12). Make this connection using an approved shield termination technique. NOTE Refer to AC B Chapter 11, Section 8 (Wiring Installation Inspection Requirements) for termination techniques. Preferred Method: Slide a solder sleeve (3) onto the prepared cable assembly (2) and connect the Flat Braid (4) to the shield using a heat gun approved for use with solder sleeves. It may prove beneficial to use a solder sleeve with a pre-installed Flat Braid versus having to cut a length of Flat Braid to be used. The chosen size of solder sleeve must accommodate both the number of conductors present in the cable and the Flat Braid (4) to be attached. Page Rev. 2

31 Solder Sleeves with pre-installed Flat Braid A preferred solder sleeve would be the Raychem S03 Series with the thermochromic temperature indicator (S03-02-R , S03-03-R , S03-04-R ). These solder sleeves come with a pre-installed braid and effectively take the place of items 3 and 4. For detailed instructions on product use, refer to Raychem installation procedure. Individual Solder Sleeves And Flat Braid Secondary Method: Solder a Flat Braid (4) to the shield exposed through the window of the prepared cable assembly (2). 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. Slide a minimum 0.75 inches of Teflon heat shrinkable tubing (3) onto the prepared wire assembly and shrink using a heat gun. The chosen size of heat shrinkage tubing must accommodate both the number of conductors present in the cable and the Flat Braid (4) to be attached. Reference the following MIL-Spec for Teflon heat shrinkable tubing (M23053/5-X-Y). 4. At the same end of the shielded cable (2) and ahead of the previous shield termination, strip back Float Min to Float Max (See Table 2-12) length of jacket and shield to expose the insulated center conductors (see Figure 2-12). The Ideal Float length may be best to build optimally. Preferred Method: The jacket and shield should be cut off at the same point so no shield is exposed. Slide 0.75 inches minimum of Teflon heat shrinkable tubing (5) onto the cable and use a heat gun to shrink the tubing. The chosen size of heat shrinkage tubing must accommodate the number of conductors present in the cable. 5. Strip back approximately 0.17 inches of insulation from each wire of the shielded cable (2) and crimp a contact (6) to each conductor. It is the responsibility of the installer to determine the proper length of insulation to be removed. Wire must be visible in the inspection hole after crimping and the insulation must be 1/64 1/32 inches from the end of the contact as shown in Figure Figure Insulation/Contact Clearance 6. Insert newly crimped pins and wires into the appropriate connector housing location as specified by the installation wiring diagrams. Page 2-21 Rev

32 7. Cut the Flat Braid (4) to a length that, with the addition of a ring terminal, will reach one of the tapped holes of the Jackscrew backshell (1). An appropriate amount of excess length without looping should be given to the Flat Braid (4) to allow it to freely move with the wire bundle. NOTE Position the window splice to accommodate a Flat Braid (4) length of no more than 3 inches. 8. Guidelines for terminating the newly cutoff Flat Braid(s) (4) with insulated ring terminals (7): Each tapped hole on the Jackscrew Backshell (1) may accommodate only two ring terminals (7). It is preferred that only two Flat Braids (4) be terminated per ring terminal. Two Flat Braids per ring terminal will necessitate the use of a Ring terminal, #8, insulated, AWG (MS ). If only a single Flat Braid is left or if only a single Flat Braid is needed for this connector a Ring terminal, #8, insulated, AWG (MS ) can accommodate this single Flat Braid. If more braids exist for this connector than two per ring terminal, it is permissible to terminate three braids per ring terminal. This will necessitate the use of a Ring terminal, #8, insulated, AWG (MS ). 9. Repeat steps 2 through 8 as needed for the remaining shielded cables. 10. Terminate the ring terminals to the Jackscrew Backshell (1) by placing items on the Pan Head Screw (8) in the following order: Split Washer (9), Flat Washer (10) first Ring Terminal, second Ring Terminal (if needed) before finally inserting the screw into the tapped holes on the Jackscrew Backshell. Do not violate the guidelines presented in Step 8 regarding ring terminals. 11. It is recommended to wrap the cable bundle with Silicone Fusion Tape (11) (GPN: or a similar version) at the point where the backshell clamp and cast housing will contact the cable bundle. NOTE Choosing to use this tape is the discretion of the installer. 12. Place the smooth side of the backshell clamp (12) across the cable bundle and secure using the three screws (13). Warning: Placing the grooved side of the clamp across the cable bundle may risk damage to wires. 13. Attach the cover (14) to the backshell (1) using the two screws (15) Configuration Module Assembly To assemble the configuration module, refer to Figure 2-16 (Figure references are in parenthesis) and complete the following steps: 1. Strip back approximately 0.17 inches of insulation from each wire of the four conductor wire harness (3) and crimp either a pin (4) or a socket (9) to each conductor. It is the responsibility of the installer to determine the proper length of insulation to be removed. Wire must be visible in the inspection hole after crimping and the insulation must be 1/64 1/32 inches from the end of the contact as shown in Figure Insert newly crimped pins (or sockets) and wires (3 and 4) into the appropriate connector housing (5) location as specified by the installation specific wiring diagram Page Rev. 2

33 3. Attach the module (1) to backshell (6) using screw (10). 4. Plug the four conductor wire harness (3) into the connector on the module (1). 5. Orient the connector housing (5) so that the inserted four conductor wire harness (3) is on the same side of the backshell (6) as the module (1). 6. Attach cover (7) to backshell (6) using screws (8). Figure Insulation/Contact Clearance Figure GTS 8XX Jackscrew Backshell Installation Page 2-23 Rev
