Connectivity and CAN Bus Products

State-of-the-art products for faster development.


Intelligent Systems / Altran offers a complete range of products to support design, development and validation of connected system.

Although some of the product can be used in a lot of different way, it is possible to categorize the products in three different families:

  • Products for Fast-Prototyping and or Hardware-In-the-Loop : MUXlab4 or MUXLab2 with MUXLink
  • Products that enable PC-to-network connectivity as well as the tools used to assist systems development and validation: MUXy light , MUXy Box2, PCI Can cards, Traminator CAN and MUXy 2010
  • Test and measurements products that can be embedded in the system (vehicle or other): MUXlog R, BI-CAN I/O gateway and MUXtester


MUXlab4 et MUXlab2

MUXlab4 et MUXlab2

MUXlab4 or MUXlab2 with MUXlink provide hardware and software solutions used to activate embedded applications for real-time computing systems based on Simulink® and Stateflow®. MUXlink provides the kits of tools needed to operate all the resources in your Simulink models that are available in the MUXlab4 hardware base (I/O, memory, CAN and LIN) and to distribute the functions in the different real-time tasks. Automatic codes are generated by Real Time Workshop® and executed in RAM or Flash. The compilation and link processes are fully integrated into the Simulink® environment and a USB interface enables application download.


MUXLink is a Software library that supports Muxlab4 and Muxlab2 products.

MUXlink includes a toolbox facilitating the use within Simulink® models of all MUXlab4 platform resources (I/O, memory, CAN, LIN) and allows the distribution of various functions throughout the real-time tasks.

The automatic code generation is provided by Real-Time Workshop®, to be used in RAM or Flash memory. Compilation and links are fully integrated with Simulink® environment.



MUXy light

MUXy light is an intelligent interface which connects a PC to a CAN bus via a USB link. The embedded software manages CAN frame segmentation and flow control in accordance with the ISO 15765 standard.

MUXy Box2

MUXy Box2 is a smart interface which can link a PC to one or several multiplexed bus, via an USB link. All critical temporal constraints related to the emulation of diagnostic protocols in K, CAN or LIN are supported by the embedded microcontroller, thus relieving the PC time management. The embedded software manages CAN frame segmentation and flow control in accordance with the ISO 15765 standard.

Can cards for PC (version for PCI)

CAN cards for PC enable the connection of the CAN bus to systems equipped with PCI buses. These cards are available with or without galvanic insulation and are supplied with software interfaces for Windows.

Traminator CAN

The CAN Traminator is a CAN computer validation tool used to generate interference, such as line opening, earthing, error-frame transmission and bit destruction, that is controlled on a CAN bus.

MUXy 2010

MUXy 2010 lets users connect a PC directly to the OBD diagnostic connector of a multiplexed vehicle via the USB link. It manages three high-speed CAN channels (one of which interchangeable with a low-speed channel), one K channel, one 2.1 fixed LIN channel (functioning as a master or slave), and two 2.1 master LIN or K channels and can be used to:

  • download the ECU’s firmware/software from within the vehicle via the BSI switched CAN
  • carry out diagnostics testing via channels K, CAN (Diag on CAN) and LIN (Diag on LIN)



MUXlog R

MUXlog R is a tool for data logging the activity of CAN and LIN vehicle buses. It can be pre-programmed to trigger a sequence of network and/or external events and features an internal clock, a high-speed CAN activated wake function and a controlled power output.

BI-CAN I/O gateway

The Bi-CAN I/O gateway lets users:

  • convert wire signals into CAN frames
  • control actuators from CAN frames
  • establish a gateway between two CAN networks (typically 250KB and 500KB)                             
  • generate analogue voltages from CAN signals


MUXtester is a hand held tool designed for full diagnostic measurement on CAN High Speed and CAN Low Speed Networks. It is a tool for use on-site and is very easy to use for non-specialists of multiplex technologies to check physical and software signals. It can check the integrity of cable beams for the embedded cable network. It provides a diagnosis support in case of failure like a multimeter. It can also visualise and check the conformity of the messages on the network by using a database downloaded by USB in the tool.

Case Reference


A major OEM needed to do functional validation on prototypes for new functionalities on old electronic architecture with some new ECUs (Electronic Central Unit). They used the MUXlab4 solution as a gateway between old and new ECUs.


A fast prototyping tool was necessary to demonstrate the feasibility of the design and respecting the tight project schedule.
Intelligent System / Altran provided the OEM with a solution based on MUXLab4 and the necessary support for the integration.
