Navigation Development System (NDS-1) Users Manual

Overview

Welcome to the Sparton Navigation Development System (NDS-1). The NDS-1 provides a simple way to

set up and evaluate Sparton’s line of navigation sensor modules, including:

–DC-4: Navigation Sensor

–GEDC-6: Gyro-Enhanced Navigation Sensor

To run the NDS-1 Navigation Development System, the following is required:

The NDS-1 Adapter Board with power adapter cord

A Sparton DC-4 or GEDC-6 navigation sensor module (purchased separately)

CD ROM disk containing the NDS-1 Host Application Software and documentation

A serial or USB cable for connection to a Windows based PC

The NDS-1 Adapter Board is shown in

Figure 1 with the navigation sensor module installed.

FIGURE 1: NDS-1 ADAPTER BOARD

The NDS-1 Adapter Board and the DC-4/GEDC-6 are

static sensitive devices. Please use proper

Electrostatic Discharge (ESD) protection procedures

when handling.

NDS-1 Navigation Development System Contents

•NDS-1 Adapter Board with power adapter (DC-4/GEDC-6 purchased separately)

•Non-magnetic Serial Cable

•USB Cable

•NDS-1 Host Application Software

•CD containing application software and documentation

FIGURE 2: NDS-1 HARDWARE

NDS-1 System Set Up

Please follow these instructions to get the NDS-1 system up and running:

1) Insert the NDS-1 Host Application CD-ROM disc into the PC (Note: PC Windows XP/Vista/7 only,

no MAC or Linux Support).

2) From ‘My Computer’ or Windows Explorer select and run setup.exe.

3) Follow the on-screen setup instructions.

4) The newly installed program can be found in the Windows ‘Start’ menu after installation.

Typically: "Start/All Programs/Navigation Development System/NDS-1".

5) Install the Sparton navigation sensor module (DC-4, GEDC-6) into the NDS-1 Adapter Board

connector (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).

Warning: Make sure the navigation sensor is mated correctly to the

interface board. Misalignment of the pins can cause serious electrical

damage to the compass. Sparton’s warranty does not cover faulty user

hardware setup.

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.

FIGURE 3: THE NDS-1 ADAPTER BOARD LAYOUT

130-7522-001

If you have chosen to connect to a PC via a RS232 port:

Short pins 1 and 2 of jumper P1 with provided jumper plug

Leave pins of jumpers P3, P4 and P7 open (factory default)

Plug the attached power adaptor into an AC outlet

Connect serial cable to DB9 connector J3. (Note: Use the provided non-magnetic serial cable to

avoid interference with sensor operations.)

If you have chosen to connect to the PC via a USB port:

Leave pins of jumper P1 open (factory default)

Leave pins of jumpers P3, P4 and P7 open (factory default)

There are two ways to apply power, either plug in the AC adapter or run the system using USB

power (+5V). It is permissible to leave the AC adapter unplugged. The AC adapter is designed to

provide clean power in electrically noisy environments.

Connect USB cable to Mini-B USB connector P2 on the NDS-1 Adapter Board.

Note 1: The USB cable has magnetic properties. An in-field calibration of the sensor must be

performed to compensate for this.

Note 2: The NDS-1 Adapter Board uses the FTDI USB to serial UART converter chip

FT232R. The target PC needs to have a USB driver for the FT232R chip installed. If not resident

on the 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). This may take a few minutes. Alternatively, the Setup Menu can be used to manually set

the COM port and baud rate.

Note 3: The NDS-1 GUI is different from that used for the Sparton SP300xD series navigation

sensores, and is required for use with the DC-4 and GEDC-6 products. The NDS-1 GUI is labeled as

such in the upper left hand corner of the GUI.

FIGURE 4: 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. Once the system connects, the COM port and baud rate are

displayed. Cancelling auto-search will bring up the dialog box for manual settings.

FIGURE 5: AUTODETECT AT BOOT UP

Manually Setting the COM port:

If auto-search is cancelled, a dialog box will be displayed (Figure 6) to allow manual entry of the COM

port and baud rate. Enter a COM port and baud rate, or choose auto detect to restart the auto detection

process. Choose cancel to exit the dialog box.

FIGURE 6: COM PORT DIALOG BOX

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. Tilt is displayed in the lower right hand corner.

Magnetic Error Meter Tilt Meter

FIGURE 7: HOME SCREEN DISPLAY

The dashboard has four pull down menus: File, View, Options and Help. The File menu allows the user to

enable the log file for data collection, download a new magnetic model to the device and exit the program.

FIGURE 8: FILE MENU

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. From this the pilot can tell whether the wings are level and if the aircraft nose is pointing above

or below the horizon. The sensor shows the imaginary aircraft's heading relative to magnetic north. The

three digital meters, roll, pitch and yaw display each reading in degrees, to a tenth of a degree.
