    If an aircraft license is required, make application for a license on FCC form 404, Application for Aircraft Radio Station License. The FCC also has a fax-on-demand service to provide forms by fax. The GDR 66 owner accepts all responsibility for obtaining the proper licensing before using the transmitter.

  • Page 14: Tso/Etso Compliance

    TSO/ETSO Deviation 1. Garmin was granted a deviation from TSO-C169a paragraph 4.a.2 to allow the unit to be perma- nently and legibly marked with a serial number and not the date of manufacture. The justification for this deviation is per FAA Memorandum “FAA Order 8150.1B, Technical Standard Order Pro- TSO-C169a gram, Policy Clarification”...

  • Page 15: Aviation Limited Warranty

    (iv) damage caused by service performed by anyone who is not an authorized service provider of Garmin; or (v) damage to a product that has been modified or altered without the written permission of Garmin. In addition, Garmin reserves the right to refuse warranty claims against products or services that are obtained and/or used in contravention of the laws of any country.

  • Page 17: Section 2 Installation Overview

    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...

  • Page 18: Installation Considerations

    In addition, the COM antenna must have at least 16 dB of isolation from other COM antennas to prevent damage to the GDR 66 COM receiver. For COM antennas mounted on the same side of the fuselage, 16 dB of isolation can be achieved by a physical separation of approximately 3 feet (0.9 meters).

  • Page 19: Cabling And Wiring

    Budget. Losses greater than 3dB can reduce transceiver range. Cabling for the GDR 66 should not be routed near components or cabling which are sources of electrical noise. Route the GPS, VOR/LOC, and Glideslope antenna cables as far as possible away from all COM transceivers and antenna cables.

  • Page 20: Mounting Requirements

    The GDR 66 must be mounted in the vertical position using the GDR 66 standalone rack. Approximately one inch of clearance should be provided on the left side of the GDR 66 to allow for cooling of the heat sink. Refer to Appendix A for outline and installation drawings.

  • Page 21: Section 3 Installation Procedure

    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.

    615725 M81969/1-04 NOTE 1. Non-Garmin part numbers shown are not maintained by Garmin and consequently are subject to change without notice. 2. Extracting the #18 or #20 contact requires that the expanded 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.

    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 Figure 3-1 TNC Connector Installation GDR 66 Installation Manual Page 3-3 190-00303-24 Revision A...

  • Page 28: 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.

  • Page 29: Serial Data

    P662 4.3.2 RS-232 The GDR 66 provides one RS-232 input and one RS-232 output. The RS-232 output conforms to EIA Standard RS-232C with an output voltage swing of at least ± 5V when driving a standard RS-232 load. The RS-232 port is used for testing and as a back up tuning port.

  • Page 30: Arinc 429

    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).

  • Page 31: Discrete I/O

    4.4.2 Key Event Out The GDR 66 provides one output to signal when the GDR 66 is transmitting, regardless of what mode the radio is in. KEY EVENT OUT* can be used as needed to decrease the sensitivity of other COM receivers on the aircraft when the GDR 66 is transmitting.

  • Page 32: 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.

  • Page 33: Acars/Selcal

    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.
