CAN Bus Multiplex Trainer

SKU: MP-1918-1

The MP-1918-1S is a single-sided CAN Bus Multiplex trainer that communicates in J-1939 protocol. Digital and analog inputs and outputs can be activated. Analog signals can be displayed using the J-1939 display. The trainer utilizes the “Moduponent®” design feature which allows unlimited expansion capabilities. This unit is equipped with an integrated electronic fault box containing 12 faults.

Spec Sheet




  • The MP-1918-1S Trainer uses SAE J1939 communications protocol to operate a 4 module CAN Bus network , which includes both a DLC and a Deutch Connector;
  • The trainer demonstrates common multiplexing circuit controls via a high speed CAN Bus network;
  • Students connect modules and components using included jumper wires;
  • The MP-1918-1S can be used as a CAN Bus demonstration trainer, or, using the included comprehensive student lab manual, as a CAN Bus training course;
  • Built in electronic fault box allows fault insertion into circuits for diagnostic training and student comprehension;
  • CAN Bus diagnostics can be taught using a DMM and DSO to look at Bus resistance, wake up signal and high speed information packets;

  • THE MP-1918-1 CAN BUS MULTIPLEX-SYSTEM TRAINER IS NOW AVAILABLE WITH ELECTUDE COURSEWARE (SOLD SEPARATELY).The CAN bus Multiplex Trainer consists of a practical set-up and the associated E-learning.

    The Trainer has a completely functioning CAN bus network consisting of four control modules, which communicate via the J-1939 protocol. The CAN bus components are connected to each other using the associated wiring set. By operating switches and sensors, analogue signals are converted to (digital) serial communication. Via measuring connections, both analog and digital signals can be measured with a multimeter or oscilloscope. In addition, sensor values can be read via the informa- tion display. The Trainer has a fault box with 12 faults and a CAN bus controlled lighting system. This makes the Trainer extremely suitable for teaching CAN bus networks, CAN bus communication, CAN bus diagnosis and CAN bus lighting systems.

    Through the preparatory theory and practical assignments, the participant learns :

  • Theoretical knowledge about CAN bus communication systems.
  • To identify the function and applications of the various CAN bus components.
  • To connect the CAN bus network step by step.
  • To measure, analyze and evaluate the power supplies, grounds, signal voltage and network resistances using a multimeter.
  • To measure, analyze and evaluate the CAN bus signal using an oscilloscope (1-channel and 2-channel).
  • To measure the wake-up signal and explain its function.
  • To observe the applications and benefits of serial communication (sharing information).
  • To apply and explain different network structures (topology).
  • In-depth knowledge about serial communication by decoding a CAN bus message.
  • To identify and explain various wiring problems and network failures using an oscilloscope (1-channel and 2-channel).
  • Includes 15 learning modules for a total of 17 hours of instruction.
