2 Device installation 2.1 Device When installing device into a vehicle please obey these instructions, otherwise your device may not work properly. Device should not be seen or easily reached. Device should be firmly fixed to a flat surface. Please avoid mounting it near the metal surfaces or cables. Device cannot be fixed to heat emitting or moving parts. Device has a built in accelerometer, therefore it is sensitive to movement. It is recommended to choose a stable installation position, where it is not subjected to vibrations and/or oscillations. Device can be fitted with double sided stick tape or zipties. Wrong device mounting may cause malfunction. SIM card should be inserted in the device while the connector is plugged off (while device has no power). 2.2 Antenna It is recommended to place GPS/GLONASS antenna behind the dashboard as close to the window as possible. 2.3 FM device firmware and configurator We recommend to use only the most recent FM device firmware and Configurator versions. You can download them from here: doc.ruptela.lt 2.4 Connections to the Power supply, GND and Ignition wires These connections are always made directly to the wires or directly to the specific connector pins. Therefore it is crucial to ensure that all connections are properly insulated. We recommend using specialized insulation methods that ensure reliable long term performance under harsh field conditions. Heat shrink connectors, crimp or solder wire connectors, insulating tape and similar materials can be used.
3 Connection and configuration for CANbus data reading 3.1 EasyCAN adapters For some installations it is mandatory to use EasyCAN adapters. Two adapter versions are available. One for the connection to the J1939 CAN line and another for connection to the J1708 line. EasyCAN - J1939 EasyCAN Volvo - J1708 Adapters allow to read data from vehicle`s system without physically connecting to the CANbus wires. It is a safe, reliable and quick way to connect. Installation instruction, supported vehicle list or other information source provided by Ruptela will specify when to use these adapters. Some of these cases will be discussed below. 3.2 CANbus data reading from LCV vehicles LCV vehicle in this case is any vehicle that requires an LCV mode set in the FM device's configuration. Usually this includes light vehicles and vans. However, there might also be some exceptions. 3.2.1 Installation instructions for LCV vehicles Before installation please refer to our installation instructions for more information. These can be acquired from our support team upon request. Instruction itself usually contains all the necessary information such as: Connection location descriptions and illustrations, which will help you to locate CANbus wires. Connector and connection method a variety of different connects could be used to access CANbus wires. In most cases you will need an EasyCAN adapter for the connection. In other cases you might need to connect directly to the wires or pins. An appropriate connection method will be specified in the instruction. Configuration description this usually includes description on LCV Group and Sub group configuration and explanations, when it is necessary to set CAN interface into the Active mode.
3.2.2 Supported vehicles lists When installation instructions are not available you could also use data provided in the supported vehicles list: https://doc.ruptela.lt/display/ab/canbus It contains summarized information, which will help you to connect and configure your FM device. If there are any exceptions, this will be also mentioned. Group column contains recommendations for LCV group configuration. By default, with the LCV configuration, CAN Active should never be used. There are few exceptions to this rule and these are marked in the table with the line (Active). This also means that a direct connection to the wires is required. Connection column contains recommendations for physical connection type. By default an EasyCAN adapter must be used. Every exception will be marked in the table with this line: "Direct connection to the wires". 3.2.3 Default installation method for LCV vehicles When you do not have access to the previously mentioned data sources or when provided information is not clear enough, you should follow our basic rules listed below. These rules will help you to complete installation safely without damaging your vehicle: When installing FM devices and preparing them to read CANbus data always use an EasyCAN adapter for J1939 CAN line. Connect it to the CAN interface on the FM device. Locate CANbus wires in the vehicle. Place these wires in the EasyCAN. Set CAN interface into LCV mode. Choose preferred LCV Group and Sub group combination manually or use? button and select your vehicle by Make, Model and Manufacture year. In the FM device configuration always set configured interface into the "silent" mode (check box Active is NOT enabled).
3.3 CANbus data reading from HCV vehicles HCV vehicle in this case is any vehicle that requires FMS, J1708 or HCV mode set in the FM device's configuration. FMS mode can be set on one of the CAN interfaces, it would looks something like this: J1708 mode can be set on RS485 interface, it would looks something like this: HCV mode is in many cases very similar to the LCV mode. It is used to read CANbus parameters from the Heavy Commercial Vehicles. In configurator it would looks something like this: HCV vehicles usually covers trucks, buses and specialized construction vehicles. However, there are also a few vans that fall under this definition. 3.3.1 Installation instructions for HCV vehicles Just as before, prior to the installation please refer to our installation instructions for more information. These can be acquired from our support team upon request. Instruction itself usually contains all the necessary information. 3.3.2 Supported vehicles lists Supported lists for trucks, buses and other vehicles in this case can be used to determine recommended CANbus data source. This can be J1939 CANbus, J1708 lines or CANbus line, where HCV mode is needed. https://doc.ruptela.lt/display/ab/canbus 3.3.3 Connection to the FMS via standard FMS connector The majority of modern trucks provide an interface for third party devices, which enables them to read truck data via FMS standard. Installation instructions by Ruptela usually describes where to find this interface, how to connect to it and what configuration to use. If there are some exceptions, this will be also mentioned. If this information is not available or provided description is not clear enough, you should follow our basic rules listed below. These rules will help you to complete installation safely without damaging your vehicle: Locate a standard FMS connector, which is usually placed somewhere in the truck's cabin. Connect FM device's CAN interface wires directly to the CAN pins in the FMS connector. In the device configuration, set CAN interface into the FMS mode, select 250 baud rate and check "Active" check box.
3.3.4 Connection to the FMS via other CANbus line There are trucks that do not have FMS connector in their standard equipment. Connection and CANbus data reading in these trucks is more complicated. As a rule some other CANbus line where data is being transmitted in FMS standard has to be used. Always use the EasyCAN for J1939 CAN for such connections. Installation instructions by Ruptela usually describes where to find CANbus wires, how to connect to them and what configuration to use. If there are some exceptions, this will be also mentioned. If this information is not available or provided description is not clear enough, you should follow our basic rules listed below. These rules will help you to complete installation safely without damaging your vehicle: Connect EasyCAN for J1939 CAN line to the CAN interface on the FM device. Locate CANbus wires where data is being transmitted in FMS standard. Place these wires in the EasyCAN. In the device configuration, set CAN interface into the FMS mode, select 250 baud rate and leave interface in the silent mode (check box "Active" NOT checked). 3.3.5 Connection to the J1708 Trucks and specialized construction vehicles manufactured in the USA, also some older trucks manufactured in Europe use J1708 standard to transmit data. In order to connect and read truck s data from such vehicles a different version of an EasyCAN adapter is required. EasyCAN Volvo is specially designed for connections to the J1708 lines. Unlike the ordinary EasyCAN for the J1939, this adapter has to be connected to the FM device s PortC (RS485) port. This means that a different configuration has to be used. Installation instructions by Ruptela usually describes where to find these J1708 wires, how to connect to them and what configuration to use. If there are some exceptions, this will be also mentioned. If this information is not available or provided description is not clear enough, you should follow our basic rules listed below. These rules will help you to complete installation safely without damaging your vehicle: In this case it is mandatory to complete FM device configuration first. For that set PortC interface into the J1708 mode. Only after device configuration you can begin device installation. Connect EasyCAN Volvo to the RS485 serial interface on the FM device. Locate J1708 wires in the vehicle. Place these wires in the EasyCAN Volvo. 3.3.6 Connection to the HCV profile J1939 CANbus line Some trucks, busses and construction vehicles use custom standards (no FMS) to transmit vehicle s data in its internal CANbus lines. To read this data you will need to configure your FM device accordingly and set a HCV mode. Always use the EasyCAN for J1939 CAN for such connections. Installation instructions by Ruptela usually describes where to find CANbus wires, how to connect to it and what configuration to use. If there are some exceptions, this will be also mentioned.
If this information is not available or provided description is not clear enough, you should follow our basic rules listed below. These rules will help you to complete installation safely without damaging your vehicle: When installing FM devices and preparing them to read CANbus data always use an EasyCAN adapter for J1939 CAN line. Connect it to the CAN interface on the FM device. Locate CANbus wires in the vehicle. Place these wires in the EasyCAN. Set CAN interface into HCV mode. Choose preferred HCV Group and Sub group combination manually or use? button and select your vehicle by Make, Model and Manufacture year. In the FM device configuration always set configured interface into the "silent" mode (check box Active is NOT enabled). 3.3.7 Connection to the J1708 and J1939 CANbus lines In some special cases both standards J1708 and J1939 are used in one vehicle. Use two EasyCANs. EasyCAN Volvo for J1708 and EasyCAN for J1939 CAN lines. Installation instructions by Ruptela usually describes where to find wires both lines, how to connect to them and what configuration to use. If there are some exceptions, this will be also mentioned. If this information is not available or provided description is not clear enough, you should follow our basic rules listed below. These rules will help you to complete installation safely without damaging your vehicle: It is mandatory to complete FM device configuration first. For that set PortC (RS485) interface into the J1708 mode. Set CAN interface into the FMS mode, select 250 baud rate and leave interface in the silent mode (check box "Active" NOT checked). If this truck requires a HCV mode, then set CAN interface into HCV mode. Choose preferred HCV Group and Sub group combination manually or use? button and select your vehicle by Make, Model and Manufacture year. Check box "Active" NOT checked.
Connect EasyCAN Volvo to the PortC (RS485) serial interface on the FM device. Connect EasyCAN for J1939 CAN line to the CAN interface on the FM device. Locate J1708 and J1939 CANbus wires in the vehicle. Place J1708 wires in the EasyCAN Volvo. J1939 wires go into the ordinary EasyCAN. J1708 and J1939 CANbus lines: CAN parameters and their values In this case FM device s configuration pays an important role. Values for CAN parameters can be obtained from both CAN lines. Three common cases are described below. Configuration case 1 PortC on FM device: J1708 CAN/CAN2 interface on FM device: FMS - or - PortC on FM device: J1708 Parameter Source Description CAN engine speed CAN Actual engine percent load CAN fuel level1 CAN engine hours CAN high resolution total vehicle distance CAN fuel rate CAN engine total fuel used CAN high resolution engine total fuel used Remaining CAN parameters Dynamic J1708 J1939 CAN/CAN2 interface on FM device: HCV HCV Group: Tractor; HCV Subgroup: Tractor1 FM device can obtain parameter values via both interfaces, however J1939 interface has a higher priority. Device checks both interfaces. If parameter values from both sources are valid, than data from J1939 CAN line will be used. If there is no data form J1939 or parameter values are invalid, then data from J1708 will be used. If there is no data form J1708 or parameter values are invalid, then data from J1939 will be used. When J1708 interface is enabled in the configuration, FM device will use data from this source to calculate parameter values. This is true even when data from the J1708 CAN line is not available. Values for the remaining CAN parameters are always obtained from the J1939 line. This is true even when data from the J1939 CAN line is not available.
Configuration case 2 PortC on FM device: J1708 CAN/CAN2 interface on FM device: HCV HCV Group: Volvo; HCV Subgroup: Volvo6 Parameter Source Description CAN engine speed CAN fuel level1 CAN fuel rate CAN engine total fuel used CAN high resolution engine total fuel used CAN engine hours Remaining CAN parameters Dynamic J1708 J1939 FM device can obtain parameter values via both interfaces, however J1939 interface has a higher priority. Device checks both interfaces. If parameter values from both sources are valid, than data from J1939 CAN line will be used. If there is no data form J1939 or parameter values are invalid, then data from J1708 will be used. If there is no data form J1708 or parameter values are invalid, then data from J1939 will be used. When J1708 interface is enabled in the configuration, FM device will use data from this source to calculate parameter values. This is true even when data from the J1708 CAN line is not available. Values for the remaining CAN parameters are always obtained from the J1939 line. This is true even when data from the J1939 CAN line is not available. Configuration case 3 PortC on FM device: J1708 CAN/CAN2 interface on FM device: HCV HCV Group: Any; HCV Subgroup: Any - or - PortC on FM device: J1708 CAN/CAN2 interface on FM device: LCV LCV Group: Any; LCV Subgroup: Any Parameter Source Description All CAN parameters J1939 and J1708 FM device can obtain parameter values form both CAN lines. Some parameters in records can have values form J1939 data, other from J1708.
3.3.8 Tachograph data reading Detailed descriptions about tachograph data reading, FM device connection and configuration can be found at doc.ruptlea.lt. Before any action regarding tachograph connection refer to this instruction first: FM-Tco4 HCV + Ruptela Tachograph Solution Below you will find just a few key points that are important to mention considering CANbus data reading: An interface for third party devices, which enables them to read truck data via FMS standard, sometimes allows tachograph data reading. This is possible when truck supports such a feature. Connection in this case should be made directly to the FMS connector pins. Also CAN interface on the FM device must be set in Active mode. In all other cases, where truck does not support such feature, standard FMS connector is not available or when EasyCANs are used (direct connection to the wires is not allowed), tachograph data cannot be obtained via same CANbus line. Then, to read tachograph you will be required to make a second connection directly to the tachograph. For that a second CAN port on the FM device can be used. It also have to be configured accordingly. A likely configuration example for such case is showed below. Here connection was made to the CANbus line, where data is transmitted in FMS standard. If this truck requires a HCV mode, then configuration would look like this:
4 Connection and configuration for OBD DTC reading Note It is possible to configure OBD on one CAN interface and LCV or FMS on the other. If LCV+OBD or FMS+OBD is configured, it is important that the OBD interface works properly! If the OBD is not receiving information (no communication), then the other interface (FMS or LCV) will not work. OBD Diagnostic Trouble Code reading is a different functionality based on other principles than previously discussed CANbus data reading. To read the codes, you will have to connect/plug the device into the 16-pin OBD II diagnostic connector, which is usually located under the dash near the steering column. For OBD DTC reading EasyCAN adapters are not needed. OBD DTC reading functionality is supported by: FM-Plug4+ FM-Tco4 HCV & FM-Tco4 LCV FM-Tco3 (special firmware version needed) All these devices support the following OBD II signal protocols: ISO 9141-2 / ISO 14230-4 ISO 15765-4 Recommendations for FM-Plug4+ configuration and connection FM-Plug4 and FM-Plug4+ are meant to be connected to the OBD II (SAE J1962) socket. Other types of OBD sockets, that conform to different standards (OBD-I; OBD-1.5; etc.) are not supported. Only FM-Plug4+ can read OBD DTC. For some vehicles OBD DTC can be obtained through the OBD CAN interface, for others through the OBD K-line. During device configuration, when preparing it to read the OBD DTC, you can choose what interface to enable. Refer to supported OBD vehicle list. In its 4th column named "Connection you will find recommendations: https://doc.ruptela.lt/display/ab/obd If a vehicle from this list in "Connection" column has K-line listed as recommended interface, then during FM-Plug4+ configuration it is also recommended to enable K-line interface. If a vehicle from this list in "Connection" column has CAN listed as a recommended interface, then during FM-Plug4+ configuration it is also recommended to enable CAN interface.
Recommendations for other FM devices Other FM devices are connected directly to the OBD CAN or OBD K-line interfaces via wires. Connection instructions available at doc.ruptela.lt. Similarly, during device configuration, when preparing to read the OBD DTC, you can choose what interface to enable. Again, refer to supported OBD vehicle list for the recommendations.
