1.5. Product Usage Notes

• To prevent ESD and EOS damage, a properly grounded ESD wrist strap should be worn

when the EVK case is opened

• Do not alter jumpers while power is applied

• Do not short the RF signal to ground if antenna supply voltage is connected. Damage to

the EVK or module may occur.

Always follow ESD safety precautions when utilizing the evaluation kit. For additional

information, contact your local sales representative.

This module shall be suppl ied by a limited power source co mplying with clause 2.5 of EN 60950-

1 and mounted on a V1 flammability class material or better.

2. Dead Reckoning Overview

Dead Reckoning (DR) is the process of estimating one’s current position based upon a previously

determined position or “fix”, and advancing that position based upon course and speed (which

could be either estimated or measured).

The SL869-ADR receiver provides the user with accurate estimates of a vehicle’s position and

speed, even during interruptions in GNSS information, combining the best features of GNSS and

Sensor navigation.

Figure 2-1 DR Operation in the absence of GNSS signals

When GN SS da ta is available, it pro v id es nav igation updates and corrections for sensor drift.

When the GNSS signal is interrupted, sensor data (speed and heading) are used to compute the

navigation solution.

The result is improved navigation in harsh environments such as urban canyons, etc.

2.1. DR Description

In a DR configuration, a discrete odometer or wheel pulse signal provides the un it w ith vehicle

speed data. This signal may be obtained from various locations in the vehicle such as the

transmission, speed display or a port on some car radios. The SL869-ADR can accept odometer

input pulses in the range of 12V.

An option for supplying the odometer or wheel tick pulse is through the on-board diagnostics

(OBDII) connector, which provides acc ess to the vehi c le’s controller area network (CAN) bus.

This can be achieved with the addition of an “OBD VSS Signal Generator” - a device that

generates a wheel pulse from the vehicle CAN bus data. Telit does not sell these dev ices.

Note: Telit currently does not support the dir ect conn e ctio n of a CAN bus.

A forward-reverse signal, usually provided by the vehicle’s transmission or a backup light circuit,

supplies directional data to the SL869-ADR module. For proper operation, th e rev erse sig na l

should be stable when on and not be pulsed.

The SL869-ADR Evaluat io n Kit (EVK) has a selection switch to invert the signal if necessary.

The SL869-ADR module also includes a set of MEMS gyros that are capab le of measuring rates

of angular motion around three axes, allowing the unit to maintain vehicle attitude data – heading,

pitch, and roll angles.

5.1. Vehicle Connections

 The SL869-ADR EVK main board is powered by the USB cable connected to a PC.

 Vehicle signals can be connected to the SL869-ADR Interface Board connector P1 (on

the EVK Unit rear panel) using the DR harness cable provided as follows:

1. An external 12 VDC supply is required.

• RED (Pin 1): +12V

• BLACK (Pin 2): Ground

2. A reverse sig nal from the vehicle is required.

• WHITE (Pin 3): Reverse signal (input)

3. The polarity of the reverse signal is set by SW1-switch 2 on the rear panel of the EVK to suit

the installation.

• If +12V signals Forward, set SW1-switch 2 UP

• If +12V signals Reverse, set SW1-switch 2 DOWN

• If not connected (e.g. for test purposes), set SW1-switch 2 UP to indicate Fo rward g ear.

4. A wheel tick signal is required.

• GREEN (Pin 4) Wheel Tick / ODO

5.2. EVK Mounting

The EVK must be positioned near the center of the vehicle and mounted securely.

The EVK must be mounted flat and with the front panel facing the front of the vehicle.

5.3. Computer Setup and Connection

Before operation, ensure that the EVK power switch is in the OFF (down) position and the

USB drivers are installed by performing the following steps:

1. Insert the USB flash drive and connect the EVK to the PC via the USB-1 connector on the

rear of the EVK. Then, turn the Power switch vertically UP to turn On the EVK.

2. As soon as the evaluation board is connected to the PC, it will be detected and the USB driver

installed.

3. Note: If a software Installation warning appears, select “Continue Anyway” option.

Figure 5-1 Hardware Installation Warning Screen

4. After the EVK is connected, check the “Device Manager” window for the evaluation board

COM port number. This information is needed for use with the GPS tools.

5. Connect the provided Active Antenna to the SMA connector.

NOTE:

On some occasions, Windows will install a Microsoft Serial BallPoint mouse after connecting

the USB. Uninstall the Microsoft Serial BallPoint mouse if Windows mistakenly installs it.

• SL869-ADR software from TELIT

• TESEOIII X-Loader v1.11 (or newer) from TELIT

7.2. Flashing Instructions

1. I nstall a shunt jumper on Main Board SL869 BOOT (pins 2 & 3), tying both pins together.

2. Connect the USB connector and let the Host PC machine enumerate the USB connection.

3. Set SW201 (Main Power) ON (up) to power the SL869-ADR receiver.

4. Launch the TESEOIII X-Loader and set the selections as shown in the figure below.

5. Click on the Load button then locate and select the provided software by Telit.

6. Verify select ions as follow s :

• “Target device” is SQI flash

• “Loading settings” is UART mode

• “Options” is “Erase NVM ”

• “STA8090FG Only” is selected

7. After selecting the correct configuration and the selected COM port is properly identified

(Look under Device Manager in Windows OS for COM port if cannot be identified/found),

click on “Send” to program the device.

When done, a pop up window will confirm, “Device successfully programmed”.

8. Remove the shunt jumper from Step 1.

9. Cycle power to EVK. Verify NMEA data is streaming out with TelitView under the NMEA

Monitor window.

8. Calibration

Once the system has been installed with desired firmware and co nnected to vehicle wheel ticks,

proper calibration is required for optimum performance.

Steps:

1. First, choose a location where there is open sky over the entire course for a good GNSS

signal. Calibration will require the vehicle to be moving.

2. Place the EVK on a flat and secure surface with the power switch facing toward the front of

vehicle and as close as possible to the center of vehicle. This will allow the gyro to stabilize

and the DR FW to store starting point parameters. Once oriented in this position, it should

remain in same direction and location to keep results consistent.

Ensure a rigid mount.

3. Connect USB from the laptop PC to the EVK port USB1, located at opposite side from the

SMA antenna connection.

4. Run TelitView on the laptop to verify NMEA output activity from the EVK when powered

on. TelitView will also allow you to see and record data from the EVK output.

5. Turn on car and the power up the EVK.

6. Synchronize the EVK to Telit view.

Note: Make sure to select correct COM port and set baud rate 115200.

7. Wait approximately 2 minutes in a stopped position with the EVK and vehicle on. This

allows the unit to initialize the yaw rate offset with reliable values. Verify a valid GNSS

position fix.

8. After 2 minutes, drive in a straight line direction for at least five minutes at a constant speed.

The speed should be greater than 35 km/h (approx. 22mph).

9. Following the straight drive, make several left and right turns of at least 90 degrees allowing

the system to calculate the gyro yaw rate gain.

Note: Calibration will be improved with more turns completed. A minimum of 10 turns is

recommended.

10. Calibration should be performed in an open sky environment. Avoid urban canyons, tunnels,

parking garages, dense foliage, etc.

To complete calibration, the vehicle should stop and remain stationary for at least 10 seconds.

For a full calibration to be successful, the above procedure must be followed.

11. Verify through the TelitView DR Control Panel that the DR Calibration Status fields are all

checked and highlighted in green as shown in Figure 6-9 DR Control P a nel View.

Another way to verify that calibration is completed is by checking NMEA message

$PSTMDRCAL,A,B,C,D,xx

If the highlighted fields (A, B, C, D) have values of ‘1’, a coarse calibration was achieved.

12. To clear calibrat ion (for testing purposes), click the “Clear Cal” button on the TelitView DR

Control Panel screen. Follow the instructions and issue a reset to complete the process.
