CAN–bus / Modules

CAN GATEWAY 

Forwarding messages between two CAN buses

The CAN-GW functions as a “gateway”, resending messages between two CAN buses. An extended version, the CAN-GW LOG, also saves in its internal memory  records on basic operating event and dignostic error messages DM1 and EDM in its memory.

Functions:

  • Gatewaying (CAN-GW)
    Information on CAN transfer speed and message table are saved in internal memory. These messages are immediately resent to the second CAN-bus after being read by the first CAN-bus. CAN-buses can have a different transfer speed.
    Resending can be set for multi-packet messages (acording to SAE J1939/21).
    The CAN-GW can analogically change a message idetifier, or modify the data field based on specific requirements.
  • Logging (CAN-GW LOG)
    These records are saved on an internal 4 MB memory:
    Key on/Key off
    Start/End of travel
    Start/End of DM1 and EDM diagnostic code error messages

All records can be supplemented with information on time and position, obtained from a GPS signal. Records on travel and diagnostic errors also contain data from the odometer. Records from the CAN-GW memory can be read and managed through the CAN.

CAN UnIO

CAN – Inputs / Outputs

The input/output convertor is used in commercial vehicles and mobile machinery. Controlling and sensing inputs/outputs and their conversion on the CAN bus according to input (possible modifications can be ordered). The actual functionality is determined by the firmware version loaded in the module.

UnIO std (Inputs / Outputs)

  • full version, contains inputs / outputs according to specification

UnIO eco (outputs only)

  • partial version, contains only outputs according to the specification

order no.:  CANUNiO

USB2CAN

USB / CAN-bus Interface

USB2CAN is an adapter to connect the CAN bus to a PC via USB. The device uses an FTDI circuit for USB communication. The SJA1000 circuit is used as a CAN bus controller, which is today the standard for the CAN – PC interface. An 18-series PIC microprocessor is inserted between the two circuits to operate both circuits, perform data transformation, and serve as an additional buffer layer. This microprocessor contains a bootloader and allows you to update the original firmware, or load specialised user firmware.

In addition to the standard sending, receiving and filtering of messages, the converter firmware contains 16 special message buffers, which are used to automatically generate these messages on the CAN bus. The generation period is adjustable from 1 to 65534 ms. The buffer for receiving messages consists of both the microprocessor memory and the FIFO memory of the SJA1000 circuit. Messages received from CAN are supplemented in the converter by a time stamp, which precisely determines the time of arrival of the message. The resolution of this timestamp is 250 microseconds.

CAN Control Center + CAN Suite 6

  • CAN Suite is a set of software applications for monitoring and analysing data transmitted via CAN buses (according to ISO 11898), especially the SAE J1939 protocol, which is widespread in commercial vehicles (trucks, buses) and mobile machinery
  • Supports other converters from other manufacturers such as UCINT II, TinyCAN, Vector, PCAN, etc.
  • Detailed information on all applications can be found here

CAN-FIRE converter

Fire vehicle system

This convertor is used in commercial vehicles and mobile machinery.

  • Vehicle fire system control unit
  • Used to indicate an increase in temperature (up to 6 heat sensors) in random parts of the vehicle and the resulting extinguishing
  • Includes software for configuring the module

 

order no.:  36-CAN_FIRE

CAN TPL4

Temperature + DM1 Converter

This convertor is used in commercial vehicles and mobile machinery.

  • To obtain information on air temperature around the vehicle (up to 4 heat sensors)
  • To facilitate implementation of the on-board DM1 diagnostics based on SAE J1939

An advantage is the user-friendly module setup using a sw application

The temperature is measured once per second.

DTC (Diagnostic Trouble Code) error codes from all DM1 diagnostic messages are stored in the convertor’s memory (i.e., “single” and multi-packet messages). The periodic “single” message includes information on the status of the diagnostic warning lights from the most important units and one selected DTC error code. The user message can be used to switch the transmission of other current error codes.

 

order no.:  36-CAN_TPL4

CANI V6R1

Converter CAN-bus / Inputs (6x voltage, 1x resistance, DM1)

The converter is used to transfer signals from analog sensors (pressures, temperatures, fuel supply…) and state switches to CAN-bus messages. To simplify the implementation of an on-board diagnostics DM1 according to SAE J1939.

The converter measures current values of 6 voltage inputs and 1 resistance input. It transmitts detected values in two CAN-bus messages periodically. In one message also the current value of supply voltage is transmitted. One version of a standard firmware interprets one of voltage inputs as an “address” – it enables to connect 4 converters on one CAN-bus (customization of the firmware is needless).

DTCs (Diagnostic Trouble Codes) from all diagnostic messages DM1 (it means “single” and also multi-packet messages) are saved in a memory of the converter. The information about a state of diagnostic lamps the most important aggregates and one selected DTC are transmitted in a periodical “single” message. Transmitting other DTCs can be switched by a user’s message.

order no.:  36-CANI_V6R1

CANO D7

Converter CAN-bus / Outputs (7x digital)

The converter is used in commercial vehicles and mobile machinery to control up to 7 state outputs by a CAN-bus message. One of firmware versions is extended by transmitting request for information about total fuel consumption to the engine.

The request is formed for two fuel options:

  • Diesel – engine responds by Fuel Consumption – Liquid message (FC_L, 18 FE E9 00)
  • CNG – engine responds by Fuel Consumption – Gas message (FC_G, 18 FE AF 00)

order no.:  36-CANO_D7

CAN-AKCEL 

Converter / Accelerator pedal convertor

This convertor is used in commercial vehicles and mobile machinery.

The CAN_AKCEL module processes analogue signals transferred from the accelerator; i.e., converting them into a value to be sent with the message, checking whether they exceed the limit values and logically checking their relations. Any errors are processed for values for transmitted error message.

order no.:  36-CAN_AKCEL
