DIGITAL TACHOGRAPH MONITORING

Project description

Millions of trucks roam highways and roads each and every day delivering goods far and wide in our planet. Logistics industry is strictly regulated in most parts of the world and especially in Europe, where digitization of tachographs is mandatory. This makes it a perfect scene for the implementation of remote data download and monitoring solution.

We glad that you decide to test our “Digital tachograph monitoring” solution.

Here you will find how to prepare and to test this solution.

What you need for a solution?

The first component of our solution is a device from Teltonika’s Professional devices family:

FMB640

FM6300

FMC640

FMM640

Any of these devices can receive tachograph and driver card files (.DDD, TGD, .V1B .C1B formats), tacho live data, and enriched Tacho/FMS data (TachoCAN) from digital tachograph via the same CAN line – it makes installation even easier. Also, the devices are capable of reading live data from digital tachograph via the K-line connection.

The next component is software dedicated to downloading and administrating digital tachograph files. There are two ways to do it. You can use special Web Tacho platform from Teltonika or develop your own software. In case you choose the latter scenario, you will be provided with a special communication protocol, which you will use when developing software solution. In case you choose Teltonika Web Tacho solution, you will be able to use our server or have application installed on your side. Either way, you are ready to go. One of the biggest advantages of using Teltonika Web Tacho application is that after the initial setup you will later receive files and data automatically.

Moreover, with the help of additional accessory Tacho Front Panel Cable you will be able to read data from the minibuses that work on 12V system. Activate the front panel interface on tachograph, connect the cable and you are ready to go.

Mounting recommendations

Connecting wires:

• Wires should be connected while the module is not plugged in.
• Wires should be fastened to stable wires or other non-moving parts. Any heat emitting and/or moving objects should be kept away from the wires.
• There should be no exposed wires. If factory isolation was removed while connecting wires, the isolation material should be applied.
• If the wires are placed in the exterior or in places where they can be damaged or exposed to heat, humidity, dirt, etc., additional isolation should be applied and the wires should not be loose.
• Wires cannot be connected to the board computers or control units.

Connecting power source:

• Be sure that after the car computer goes to sleep mode, power might be still available on the power wires. Depending on car, this may happen in 5 to 30 minutes period.
• When module is connected, measure voltage again to make sure it did not decrease.
• It is recommended to connect to the main power cable in the fuse box.
• 3 A, 125 V external fuse shall be used.

Connecting ignition wire:

• Be sure to check if it is a real ignition wire i. e. power does not disappear after starting the engine.
• Check if this is not an ACC wire (when key is in the first position, most of the vehicle electronics are available).
• Check if power is still available when you turn off any of vehicles devices.
• Ignition is connected to the ignition relay output. As alternative, any other relay, which has power output when ignition is on, may be chosen.

Connecting ground wire:

• Ground wire is connected to the vehicle frame or metal parts that are fixed to the frame.
• If the wire is fixed with the bolt, the loop must be connected to the end of the wire.
• For better contact scrub paint from the spot where loop is going to be connected.

|| NOTE: PAY ATTENTION! Connecting the power supply must be carried out in a very low impedance point of on-board vehicle network. These points in the car are the battery terminals. Therefore, we recommend connecting the power of FMB640, FMC640, FMM640 and FM6300 (GND and POWER wires) directly to the battery terminals. Another valid option is to connect the wires to the main POWER cable inside the fuse box (if there is none, then to the power supply where the fuses of vehicle’s computer are), GND wire must be connected in a special point, designed to connect GND vehicle computer. Connecting the GND at an arbitrary point to the mass of the car is unacceptable, as static and dynamic potentials on the line GND will be unpredictable, which can lead to unstable FMB640 operation and even its failure.

Configuration

2. Configuring Digital Tachograph Monitoring:

SUPPORTED TACHOGRAPHS AND FORMATS

Solution supports not only the standard DDD file extension, but also Spanish TGD and French V1B, C1B file formats. You simply set required one in Web Tacho user settings.

Supported devices are: Siemens VDO Digital Tachograph – DTCO 1381 (release 1.3a, 1.4 or later) and Stoneridge Tachograph – SE5000 (release 7.1 or later). Version can be checked on tachograph or in cheque as shown in pictures below:

CONNECTING TO TACHOGRAPH

Before connecting tachograph wires, it is required to measure CAN line resistance while tachograph is switched off:

    1. Turn off the vehicle ignition;

    2. Measure resistance between the C5 (CAN2 H) and C7 (CAN2 L) contacts;

    3. If the multimeter shows ~120 Ohms, skip the next step;

    4. If the multimeter shows kilo Ohms resistance then it is needed to connect tachograph C8 (CAN-RES) and C7 (CAN2 L) contacts with wire and then perform further actions;

    5. Re-measure the resistance of the line – it has to be ~120 Ohms.

    6. Connect CAN2 L and CAN2 H wires to tachograph (C5 (CAN2 H) and C7 (CAN2 L))

• All of the same level CAN-L and CAN-H wires must be interlaced with each other.

• CAN wires need to be installed as far as possible from GSM antenna.

Below is wiring diagram of Tachograph and FM6400/FMB640 device:

CHECKING CONNECTION (TACHOCHECK SMS)

After successful connection “tachocheck” sms message can be sent to device for checking if data presented on connected lines, by another words if connections were done correctly. It is used for getting status information. SMS response is of such structure: CAN_2:[TRC],[ABCD], K-Line:[K]

[T] – Tachograph presence on bus:

 • 0 – Tachograph doesn’t respond on bus;
 • 1 – Tachograph responds on bus.

[R] – Response to Open Remote Session validity check:

 • 0 – Wrong or unknown response (failed to open Remote Session);
 • 1 – Tachograph responds positively (Remote Session opened successfully).

[C] – Response to Close Last Authentication Session validity check:

 • 0 – Wrong or unknown response (failed to close last authentication session);
 • 1 – Last authentication session closed successfully, device is ready to open new authentication session.

[K] – K-Line data presence on bus:

 • 0 – K-Line data not present on bus;
 • 1 – K-Line data present on bus. 7 [ABCD] – FMS data presence on bus:

• 0000 – FMS data not present on bus

• Non-zero – FMS data detected on bus.

SMS answer which shows correct line connections looks like “CAN_2:[111],[ABCD], K-Line:[K]”. Such SMS answer means DDD files can be downloaded from tachograph.

CONFIGURING DEVICE

In FMB640 configurator “CAN/Tachograph” section tachograph settings should be set in order to download files.

DDD download source – to which CAN line tachograph is connected;

Tachograph ignition source – which DIN is connected to vehicle ignition ("Ignition" parameter - tachograph ignition source will be the same as configured in "System" -> "Ignition Source");

WEB Tacho Settings:

Status - functionality enabling;

Domain – server domain where files will be send;

Port – server port where files will be send;

Start delay – delay after turning on ignition to start procedure of file sending.

Remote Data Download (RDD) via FMS

When RDD (Remote Data Download) signal available on FMS.

Applies to:

• DAF CF - LF - XF
• IVECO Stralis I / II/ Hi-Way
• Renault D / Magnum DXI & E-TECH / Midlum DXI / Premium DXI / Renault T-K-C
• Volvo FH - FM - FL

If the RDD signal is available on the FMS interface, no additional connection is required. In this case, the CANx LOW and HIGH wires from the FMx640 are connected to PIN 6 and 9 on the FMS connector. Additionally, PIN 10 can be used for ignition detection using DIN1 wire.

More information about FMS CABLE can be found on Teltonika Page

For the following vehicles regarding the RDD, please contact the manufacturer:

• MAN TGX - TGA - TGL - TGM
• Mercedes Actros / Antos / Atego / Arocs / Axor II
• Scania R - P - G - S

If the RDD signal is NOT available on the FMS interface, you need to retrieve the RDD data by connecting to the tachograph's C connector using provided instructions below.
