8. OPERATION The GDC64 receives aircraft data via several input methods, and then delivers that data to the ipad. The GDC64 has three input paths: ARINC 429 (4 ports) RS-232 (1 port) Discretes (8 input pins) The GDC64 has one output path: USB to ipad (1 port) An ipad app is used to configure the GDC64. The app (available on the App Store) is called GDC64. See TABLE IX for compatibility details. The ipad uses a system called the Core Location framework. The Core Location framework enables the ipad to determine its current position anywhere in the world 11. Many apps (developed by Apple or by third parties) make use of the Core Location framework in order to identify their current position. The Core Location framework takes inputs from a variety of sources including the ipad s onboard GPS, wireless network information, cellular network information (on select ipads only), and NMEA input. The GDC64 outputs an NMEA string for use by the Core Location framework. This enables any app which utilizes the Core Location framework to have access to the GDC64 NMEA output. TABLE IX. GDC64 App/Firmware Compatibility System Software Version Legacy GDC64 App Version 12 GDC64 0050 006A 11 Accuracy of this position is affected by the various inputs to the Core Location framework. 12 Due to software/app compatibility requirements, all units utilizing system software version 0050 or earlier must use the Legacy GDC64 app. Units utilizing system software version 006X or later must use the GDC64 app. Both apps can be found in the App Store. 1104-2510-01 Revision C Page 12 of 34
8.1. Inputs 8.1.1. ARINC 429 Input The GDC64 has four ARINC 429 input ports. These ports (0, 1, 2, and 3) are configured by default as shown in TABLE IX. TABLE X. Software Version 0050 Factory Default Label Sets Port 0 (FMS bus) Port 1 (GNSS bus) Port 2 Port 3 203 Altitude 076 Altitude 310 Latitude 103 Track Angle 311 Longitude 110 Latitude 312 Ground Speed 111 Longitude (user configured) (user configured) 313 Track Angle 112 Ground Speed 120 Latitude, Fine 121 Longitude, Fine When the GDC64 receives ARINC 429 data, it processes the data in two ways. 1. First, the values for altitude, latitude, longitude, ground speed, and track angle are replicated in NMEA format once per second. This NMEA data is delivered to the ipad for use in its Core Location framework. This enables any app which relies on the ipad s Location Services to obtain this data. 2. Second, all ARINC 429 data which is received by the GDC64 is delivered to the ipad and stored in a DAC special library. This library can be accessed by custom, third party applications which require access to aircraft position and flight data beyond what is included in the NMEA data set. 8.1.2. RS-232 Input The GDC64 is also capable of receiving serial data via its RS-232 port. This serial data is delivered to the ipad and stored in a DAC special library. This library can be accessed by custom, third party applications and may serve a variety of functions. An example of the utilization of this data would be the retrieval of weather data for use as an overlay in a mapping application or pass through of ADSB data, etc. 8.1.3. Discrete Inputs The GDC64 is configured with eight (8) discrete input pins. The discretes are not configured to perform a default function. Third party applications may be configured to read the discretes as necessary. 1104-2510-01 Revision C Page 13 of 34
8.2. Output All data output by the GDC64 is transmitted to the ipad via USB. 8.3. Software Installation 8.3.1. GDC64 The GDC64 is delivered from the factory with all required software installed. 8.3.2. ipad App An ipad app is used to manage the GDC64 configuration. The app, called GDC64 13, is available on the Apple App Store; simply search for GDC64. The app performs the following functions: 1. Provides the setup interface for configuration of the GDC64 2. Allows for selection of which labels will be passed through for each individual 429 input in addition to the default labels for Ports 0 and 1. 3. Provides a means to monitor each input port, discrete inputs, and system status 8.3.2.1. NMEA Output Without GDC64 app The ipad can utilize the GDC64 NMEA output without the GDC64 app being installed on the ipad. When the ipad is connected to the GDC64 without the GDC64 app installed an ios notification may be displayed indicating The device is not recognized. The Ignore option can be selected to disregard this message. NMEA output will continue to be delivered to the Core Location framework and the ipad will still be able to utilize this data. 13 See TABLE IX for more detail about the GDC64 app and system software/app compatibility 1104-2510-01 Revision C Page 14 of 34

APPENDIX A. GDC64 AIRCRAFT ENVIRONMENT TEST PROCEDURE This Appendix describes procedures that will test the Aircraft environment. The following tests are detailed below: Power/Charging Verification Serial Weather Input Verification ARINC 429/743 Input Verification A.1. Required Equipment/Configuration 19 ipad with ios 5.1 through ios 8.2 20 and the GDC64 App (obtained from the App Store) GDC64 installed IAW Installation Manual, 1104-2510-01 (this document), and any additional installation requirements GDC64 with SW version 0050 or later A.2. Power/Charging Verification This test will verify that when connected to the GDC64, the ipad recognizes the external power source and, if necessary, charges the battery as expected. A.2.1. Detailed Steps Connect ipad to GDC64 Ensure power is applied to the GDC64 Verify that the battery icon in the upper-right corner of the status bar indicates the ipad is either charging, or connected to a power source o NOTE: Power icons may vary in style depending on ios version installed on ipad Power/Charging verification complete 19 See TABLE IX for more detail about the GDC64 app and system software/app compatibility 20 ios 8.3 introduced a change which removes support for all hardware devices utilizing a specific interface protocol. This change prevents devices which utilize this protocol from accessing location information. ios 8.3 is not a supported version for use with the GDC64. 1104-2510-01 Revision C Page 30 of 34
A.3. Serial Weather Input Verification This test will verify the following: serial port wiring is correct XM receiver will send and receive data GDC64 transmits XM weather data to the ipad in a USB format suitable for display on the ipad A.3.1. Detailed Steps Remove power from the XM receiver Connect the ipad to the GDC64 Ensure power is applied to the GDC64 On the ipad, start the GDC64 maintenance app At the bottom of the screen, select ARINC to switch to the ARINC port monitoring tab (See FIGURE 8) FIGURE 9. ARINC Port Monitoring Tab Select Serial String Data to observe the data being received on the serial port (See FIGURE 9) FIGURE 10. Serial String Data 1104-2510-01 Revision C Page 31 of 34
Apply power to the XM receiver Using the ipad, verify the data stream in the Serial String Data Window displays data similar to Figure 10. o NOTE: Due to differences in weather receiver software versions, there may be variations between the example in FIGURE 11 and live data on the aircraft. The data stream should indicate hex data followed by ASCII characters similar to FIGURE 10. NOTE the last ASCII characters at the end of the string when connected should spell: X-Stream.(WX).V1.56.H9 The version may vary for different receivers depending on the receiver software installed. This verifies the GDC64 can receive serial data from an XM Receiver, reformat the data, and transmit it to the ipad. FIGURE 11. Serial String Data Display 1104-2510-01 Revision C Page 32 of 34
A.4. ARINC 429/743 Port Verification This test will verify the proper functionality of the known label inputs and data for the ARINC 429 inputs. NOTE: Refer to TABLE XII and TABLE XIII for complete listings of the supported label sets by software version. These labels comprise the NMEA thread the GDC64 sends to the ipad to store in the ipad Navigation Data location used by all Apps to gather info. To enable other labels on multiple ports requires user knowledge of aircraft 429 busses. A.4.1. Detailed Steps Connect the ipad to the GDC64 Ensure power is applied to the GDC64 On the ipad, start the GDC64 maintenance app At the bottom of the screen, select More FIGURE 12.
