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 the App Store) is called GDC64.
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 world9. 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 a 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.
9
Accuracy of this position is affected by the various inputs to the Core Location framework.

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 IX. Software Version 0050 Factory Default Label Sets
Port 0 (FMS bus)
Port 1 (GNSS bus)
203 Altitude

112 Ground Speed
Port 2
Port 3
(user configured)
(user configured)
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.
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 B

DAC International, Inc.
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, 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.

*NOTE: Output current from the GDC64 is sufficient to charge and maintain power for all models of iPad however, due to
voltage drop in installation wiring, the recommended maximum length for USB cabling is 9ft. See FIGURE 1 for more
information.
*NOTE: Newer models of iPad and iOS require use of Apple approved USB cables only. Third party cables may not
function properly.

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



iPad with iOS 5.1 or later and the GDC64 App, version 0020 or later (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




1104-2510-01 B.docx
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

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 8. ARINC Port Monitoring Tab

Select Serial String Data to observe the data being received on the serial port (See FIGURE
9)
FIGURE 9. Serial String Data
1104-2510-01 B.docx
Installation Manual, GDC64
1104-2510-01 Revision B
Page 31 of 34
DAC International, Inc.



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.

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 11. Software System Environment






In the left pane select Enable Label
Select the desired port # and the label to enable
Press Enable
Select any additional ports/labels, as desired
After selecting the desired ports/labels, at the bottom of the screen, select ARINC to switch
to the ARINC port monitoring tab (See FIGURE 8)
Ensure Label Data is being displayed for the selected ports and labels
o

A.5. Maps, Current Location
Any navigation program using the iPad Core Location framework will either indicate the current
location on its map or center the map on the current location. See FIGURE 12 for an example of the
iPad Maps app utilizing the GDC64 current location.
