General Description 1 GENERAL DESCRIPTION 1.1 Scope The information in this manual is STC approved. Only the equipment interfaces covered in this manual are within the scope of this STC. Other equipment may be suitable for use with the GDL 69/69A, but use of such equipment is beyond the scope of this STC - additional FAA approval may be required if equipment not covered in this manual is used to interface to the GDL 69/69A. This document describes the GDL 69/69A operating with software Version 2.11, 2.13, 2.14, 3.00, 3.01, 3.02 and later. Refer to Section 6, Limitations for additional information. It is possible for installers to seek evaluation and approval of an alternate installation by means of the field approval process. This manual and all the data contained within may be used by the installer in pursuit of a field approval. 1.2 Introduction This manual presents mechanical and electrical installation requirements for installing the GDL 69/69A and XM antenna (GA 55, GA 55A and GA 57) as part of the G1000 Integrated Cockpit System (GDU 104x), connected to the MX20 Multi-Function Display (MFD), or the 400/500 series displays. (See Table 1-1 for a list of 400/500 series units). The GDL 69/69A can be integrated into a variety of airframes under an appropriate TC or STC. Each airframe installation may vary. Interconnect drawings and procedures that are approved by the aircraft-manufacturer should be used during actual installation. Figure 1-1. GDL 69/69A Unit View 1.3 Equipment Description The GDL 69/69A is an XM Satellite Radio data link receiver. Two models are available; the GDL 69 is a weather data receiver. The GDL 69A is the same as the GDL 69 with the addition of XM Satellite Radio audio entertainment. For display of weather information and control of audio channel and volume, the GDL 69/69A may be interfaced to the MX20 MFD or 400/500 series units via an RS-232 bus or the GDU104x via an Ethernet link. Audio volume and channel changes may also be controlled with remotely mounted optional switches located in the cabin. The GDL 69A is also interfaced to a Garmin audio panel for amplification and distribution of the audio signal. The XM Satellite Radio antenna receives the XM Satellite Radio data signal and passes it to the GDL 69/69A. GDL 69/69A Installation Manual 190-00355-02 Page 1-1 Revision E
