Hardware and software


The PSI5-Simulyzer is an interface box, with which data can be read out quickly and easily on the one hand, and on the other hand, simulation data can be used to actively intervene in the process.

  • Simplified development of sensor technology
  • Visualization / analysis tools in the PSI5 software
  • Test and simulation function

Professional data simulation

Facts about the PSI5-Simulyzer

In addition to the standard version, SesKion also offers modified versions as well as advanced hardware and software solutions for special measurement requirements.

  • Standard Windows Gui application (optional): The protocol-specific Gui application offers a wide range of settings from the definition of signals, baud rates and error detection to trigger events. The visualization of the PSI5 bus communication facilitates troubleshooting and can also be easily saved. The PSI5 data is recorded with time stamps, whereby both import and export of data is possible.
  • API-ANSI-C (included in the box)
  • LabVIEW Lib (optional)
  • EMC Test (optional)
  • Sensor Programmer-Software (optional)
  • Sensor test software for up to 5 PSI5 boxes (optional)

PSI 5 is a cost-effective sensor interface which is frequently used in the automotive sector. The control unit communicates with one or more peripheral sensors. Sensor data is transmitted by current modulation on the supply lines.
PSI5 uses data frames with two start bits, 8 to 24 user data and one parity or optional three CRC bits. A data transmission period is initiated by a voltage synchronization signal from the ECU.


    The optoPSI5 by mk-messtechnik GmbH is an optical transmission system of PSI5-signals which can be used in EMC test environments to bring a PSI5 interface with fiber optics into the test camber.
