(the connector is keyed) per Figure 1. 6) Connect the NDS-1 Adapter Board to the PC using one of the provided cables. (Note: It is preferential, although not required, to use the serial cable due to its non-magnetic properties). - Page 6 130-7522-001 7) The NDS-1 Adapter Board has several jumper blocks (Figure 1) as noted by Adapter Boards silkscreen as P1, P3, P4 and P7. These connectors are further described in the NDS-1 Navigation Development System Users Guide. Follow the applicable instructions below depending upon whether USB or RS232 cable connectivity is chosen.
- Page 7 PC, the driver and the applicable instructions can be downloaded from FTDI website: http://www.ftdichip.com/FTDrivers.htm 8) Start the NDS-1 Host Application by double clicking on the NDS-1 icon as found on the ‘Start’ menu bar. The software will search for the correct COM port and baud rate (factory default is 115.2K baud, COM1).

Page 8: Guided Tour Of The Nds-1 Host Application
Guided Tour of the NDS-1 Host Application Boot up screen: When the program is started, a dialog box will be displayed as the system searches for the NDS-1 adapter board and DC-4/GEDC-6 navigation sensor module. The status is displayed in the lower left hand corner as the system scans available COM ports. - Page 9 130-7522-001 Home Screen: After successfully connecting to the NDS-1 adapter board, the NDS-1 Host Application dashboard will be displayed. The home screen dashboard includes meters to display the sensor heading, pitch, roll and magnetic error. In addition, the raw data from the magnetometer, gyro (if applicable), accelerometer and heading are displayed.
- Page 10 130-7522-001 The View menu provides access to the strip chart recorder, cockpit display and device variables. FIGURE 9: VIEW MENU The cockpit view is shown in Figure 10. It is designed to emulate the view within an airplane’s cockpit. The attitude indicator (also known as an artificial horizon) shows the aircraft's attitude relative to the horizon.
- Page 11 130-7522-001 The strip chart recorder displays data from all six sensors, magnetometers in milligauss, accelerometers in mili-g, and gyro data in degrees per second. FIGURE 11: STRIP CHART VIEW Selecting the File menu ( Figure 12) reveals the Save Log As menu. Selecting this option will save strip chart data to a log file. The log file is a .cvs file and can be imported into a spreadsheet for analysis.
- Page 12 130-7522-001 The Options menu provides access to the following commands: Settings, Auto Variance, Calibration, Orientation, Baud Rate, Terminal Emulator, Reconnect and Test Commands. FIGURE 13: OPTIONS MENU Auto Variance: Entering latitude, longitude, altitude and the day into the auto variance calculator will compute the magnetic variance value.
- Page 13 This drop down provides the options for mounting the DC-4 or GEDC-6 navigation sensor in the mounting platform. There are five choices (horizontal, vertical, left Edge, right Edge or inverted). For more information and graphical representations of these orientations please reference the Sparton Navigation Sensor product Guide.
- Page 14 The Baud Rate menu allows manual selection of the Baud rate for communicating with the NDS-1 adapter board. Due to the large amount of data required to update the GUI display, baud rates below 9600 are not allowed when using the NDS-1 GUI software. Note: Jumper P3 and P4 must not be present for proper operation.

Page 29: Using The Terminal Emulator
The 2-D in-field magnetic calibration mode exists for applications that move in a plane such as a ground vehicle. Applications like this are usually constrained to rotation on a single axis. Sparton’s navigation products are capable of being calibrated in any one of three planes defined by XY, YZ, or XZ relative to the sensor. -
