2 INSTALLATION OVERVIEW 2.1 Introduction This section provides hardware equipment information for installing the GDR 66, related hardware, and antennas. Installation of the GDR 66 must follow the aircraft TC or STC requirements. Cabling is fabricated by the installing agency to fit each particular aircraft. The guidance of FAA advisory circulars AC 43.13-1B and AC 43.13-2B, where applicable, may be found useful for making retro-fit installations that comply with FAA regulations. 2.
2.3 Installation Considerations Fabrication of a wiring harness is required. Sound mechanical and electrical methods and practices are required for installation of the GDR 66. 2.3.1 Antenna Considerations Antenna installations on pressurized cabin aircraft require FAA approved installation design and engineering substantiation data whenever such antenna installations incorporate alteration (penetration) of the cabin pressure vessel by connector holes and/or mounting arrangements.
2.4 Cabling and Wiring Refer to the interconnect examples in Appendix B for wire gauge guidance. The power connection can be run with three AWG #18 wires back to the breaker or can be spliced near the unit to one AWG #16 or larger wire. Special thin-wall heat shrink tubing is also provided to insulate the extended barrels inside the backshell. If using AWG #18 barrel contacts, ensure that no two contacts are mounted directly adjacent to each other.
2.6 Mounting Requirements R AF T The GDR 66 mounting surface should be capable of providing a sufficient electrical bond to the aircraft to minimize radiated EMI and provide protection from High-Intensity Radiation Fields (HIRF). Bonding resistance measured between the GDR 66 standalone install rack and the airframe should be less than 2.5 mlliOhms. The GDR 66 must be mounted in the vertical position using the GDR 66 standalone rack.
3 INSTALLATION PROCEDURE 3.1 Unpacking Unit Carefully unpack the equipment and make a visual inspection of the unit for evidence of damage incurred during shipment. 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. Retain the original shipping containers for storage.

3.4 Cable Installation R AF T 1. Route the coaxial cable to the rack location keeping in mind the recommendations of Section 2. Secure the cable in accordance with good aviation practice. 2. Trim the coaxial cable to the desired length and install the TNC connector per the cabling instructions on Figure 3-1. If the connector is provided by the installer, follow the connector manufacturer’s instructions for cable preparation.
3.5 Backshell Assembly The GDR 66 connector kit includes two Garmin backshell assemblies. Garmin’s backshell gives the installer the ability to easily terminate shield grounds at the backshell housing. Refer to the Jackscrew Backshell Installation Instructions (Garmin part number 190-00313-11) for backshell assembly instructions. 3.6 Final Installation For final installation and assembly, refer to the outline and installation drawings shown in Appendix A of this manual.

4.2 Power Functions 4.2.1 Aircraft Power The GDR 66 provides two aircraft power bus inputs. Pins 28, 30, and 32 of P662 are internally connected to form AIRCRAFT POWER 1. Pins 34, 36, and 38 of P662 are internally connected to form AIRCRAFT POWER 2. AIRCRAFT POWER 1 and AIRCRAFT POWER 2 are “diode ORed” to provide power redundancy. Use of three AIRCRAFT POWER pins (either AIRCRAFT POWER 1 or AIRCRAFT POWER 2) and three POWER GROUND pins is recommended for all installations.

4.3.3 ARINC 429 The GDR 66 provides five configurable ARINC 429 inputs and two configurable ARINC 429 outputs conforming to ARINC Specifications 429P1-17, 429P2-16 and 429P3-18. The ARINC 429 outputs conform to ARINC 429 specifications when loaded with up to five standard ARINC 429 receivers. The speed of the ARINC 429 outputs can be configured for low speed (14.29 kHz) or high speed (100 kHz).
4.4 Discrete I/O 4.4.1 Active Low Discrete Inputs The GDR 66 provides 8 configurable discrete inputs conforming to: Low: 0 VDC < Vin < 3.
4.5 Audio When the GDR 66 is in analog voice mode (ARINC 716 Voice), audio from the microphone and audio to the headset can be transferred to/from the GDR 66 as analog audio or digital audio. If analog audio is used, the COM MIC KEY* discrete input must be used. If digital audio is used all of this information is transferred in the digital audio stream. 4.5.1 Analog Audio 4.5.1.1 Com Mic Audio T The GDR 66 provides one microphone audio input.
4.5.1.4 Com Remote Transfer The GDR 66 provides one COM REMOTE TRANSFER* input which allows the COM Emergency State to be entered or exited. When the GDR 66 enters Emergency State, it automatically switches to AM COM mode and tunes to the emergency channel, 121.500 MHz. When in Emergency State, the GDR 66 ignores inputs from the front panel controls for COM selections and cannot be used for digital data link.
