FMB641 supports CAN adapters over RS232 connection. CAN adapter support is added from 02.02.11.Rev.00 firmware
Easy steps to install and configure following CAN adapters on FMB641 device:

Installing CAN adapter with FMB641 device

Installing LV-CAN200

You can watch LV-CAN200 installation video in our YouTube channel here or follow connection instructions below.

Tools needed for installation

  • LV-CAN200
  • Connection scheme (Please contact Teltonika Sales Representative and provide information about vehicle manufacturer, model and year.
  • FMB641 device
  • Pliers
  • Quick splice connectors (If vehicle CAN bus wires are very thin CAN adapter wires should be connected directly)
  • Plastic pry tool
  • Zip ties

Installation steps

  1. Be ready with a vehicle connection scheme that you have received from a Teltonika Sales Representative.
  2. Check the scheme for the current vehicle connection. Look for connectors matching PINs numbers and colors (maybe different) according to the connection scheme.
  3. Connect CAN adapter with FMB641:
    1. Connect CAN adapter's RS232 to RJ45 of FMB641.
  4. Connect CAN adapter CAN wires (CAN L, CAN H) as specified in connection scheme.

     
    Do not swap CAN L and CAN H lines.
    Not all CAN adapter wires may be used in the vehicle.

  5. Connect CAN adapter positive and ground wires to the vehicle power supply lines or near FMB641 power wires.

     
    Do not swap power supply lines.
    Make sure that voltage does not exceed 30V.

  6. Switch vehicle ignition to ACC position. CAN adapter LED diode on the back should start blinking.
  7. Configure CAN adapter to read CAN bus data or control vehicle by setting its program number - CAN Adapter configuration


 
LV-CAN200 connection example. This is not a connection diagram for your vehicle. Every vehicle has a specific scheme.


Installing LV-CAN200 + ECAN02

Tools needed for installation

  • LV-CAN200
  • Connection scheme (Please contact Teltonika Sales Representative and provide information about vehicle manufacturer, model and year.
  • ECAN02 (Used for contactless connection. If two CAN lines need to be connected, ECAN02 must be used.)
  • FMB641 device
  • Pliers
  • Quick splice connectors (If vehicle CAN bus wires are very thin CAN adapter wires should be connected directly)
  • Plastic pry tool
  • Zip ties

Installation steps

  1. Follow the same 1, 2, 3 installation steps as with LV-CAN200 installation.
  2. Connect the appropriate CAN bus pair of wires between the CAN adapter and ECAN02:
    If CAN1 line need to be connected as specified in the connection scheme:
    1. Connect CAN adapter CAN1 L to CAN L of ECAN02.
    2. Connect CAN adapter CAN1 H to CAN H of ECAN02.
    If CAN2 line need to be connected as specified in the connection scheme:
    1. Connect CAN adapter CAN2 L to CAN L of ECAN02.
    2. Connect CAN adapter CAN2 H to CAN H of ECAN02.

       
      Do not swap CAN L and CAN H lines.
      Not all CAN adapter wires may be used in the vehicle.

  3. Fasten ECAN02 on vehicle CAN bus wires according to the connection scheme. Make sure CAN H and CAN L of vehicle corresponds to CAN H, CAN L markings on ECAN02 PCB.

  4. Connect CAN adapter positive and ground wires to the vehicle power supply lines or near FMB641 power wires.

     
    Do not swap power supply lines.
    Make sure that voltage does not exceed 30V.

  5. Configure CAN adapter to read CAN bus data by setting its program number - CAN Adapter configuration


CAN Adapter Configuration

CAN Adapter program number selection


CAN Adapter must be set to the program number which depends on the vehicle model. Needed program number is always written on CAN Adapter mounting scheme. In order to be able to enter the program number in the adapter Software date of the CAN adapter must be newer than the connection scheme date. CAN adapter Software date can be checked:

The number of digits required to enter the correct Program No. may vary depending on the Software and manufacture date of your CAN Adapter:

Entering via SMS command


Required conditions:

  • CAN adapter properly connected to FMB641 device

CAN adapter program number can be set remotely, using an SMS command. Send following SMS command to FMB641 device:

  • If you have set SMS login and password: login pass lvcansetprog X
  • If SMS login and password are not set leave two spaces before the command:   lvcansetprog X

Command example:   lvcansetprog 11434
SMS response: LVCAN ProgNum: 11434

If during SMS command FMB641 was in the following Sleep mode:

Entering via Teltonika Configurator


Required conditions:

  • CAN adapter properly connected to FMB641 device

CAN adapter program number can be set via Teltonika Configurator → LVCAN → Program Number. When the program number is entered press   Save to device button that saves the entered program number into FMB641.

 

Entering manually


Required conditions:

  • CAN adapter properly connected to FMB641 device
  • Vehicle ignition must be ON

Depending on the used CAN Adapter, the length of the setup sequence will vary.

Steps to set program number:

 
LV-CAN200 back
For LV-CAN200
3 digit
For LV-CAN200
4 digit
For
LV-CAN200
>5 digit
1. Hold SWITCH down until LED stars blink.
2. Release the SWITCH.
3. Then the LED starts blinking and counting the first digit of the program number (one blink means digit 1, two blinks mean digit 2, etc). To stop the counter, push SWITCH.
4. Release the SWITCH, then the LED starts blinking and counting the second digit of the program number. To stop the counter, push SWITCH.
5. Release the SWITCH, then the LED starts blinking and counting the third digit on the program number. To stop the counter, push SWITCH.
6. Release the SWITCH, then the LED starts blinking and counting the fourth digit on the program number. To stop the counter, push SWITCH.
7. Release the SWITCH, then the LED starts blinking and counting the fifth digit on the program number. To stop the counter, push SWITCH.
All Devices 8. Release SWITCH, if programming is successful LED will blink 10 times.

Send data with 0 if the ignition is off

Depending on CAN Adapter I/O parameters and ignition status, FMB641 can send locked (last known) CAN Adapter I/O and active (real-time) parameter values or reset values to 0. When the ignition is off, CAN Adapter I/O parameters values sent to the server are:

SMS/GPRS Commands

CAN Adapters have several dedicated SMS/GPRS commands.
SMS command structure:

<SMS login><space><SMS password><space><command><space><value>

SMS command lvcangetinfo example:

  • If you have set SMS login and password: login pass lvcangetinfo
  • If SMS login and password are not set leave two spaces before the command: aalvcangetinfo


GPRS commands require Codec 12 protocol.
