VT2710 and PSI5SENTpiggy

Serial Interface Module

The module VT2710 enables the test of serial communication between an ECU and one or several digital sensors. Either the ECU or the sensors can be simulated. Tracing of the communication between real ECU and real sensors is possible as well. The module addresses two groups of serial interfaces:

  • The automotive sensor interfaces PSI5 and SENT and
  • the universal digital interfaces SPI, I2C, UART, RS232, RS422, RS485 or LVDS.

To operate the automotive sensor interfaces, the CANoe option Sensor as well as one PSI5SENT piggy per channel is required additionally. VT2710 supports max. 4 automotive sensor channels per module.

Functions for Universal Digital Interfaces

  • Two digital interfaces with 8 I/O pins each
  • Internally generated or externally supplied digital voltage per interface
  • Each I/O pin can be used as input or output
  • Simulation of an SPI master or up to 5 separately controllable SPI slaves on 2 channels
  • UART or RS232 on 2 channels each (supported from CANoe 10.0 SP). For UART, the voltage level can be adjusted
  • Two RS485/RS422 channels for half duplex operation with switchable 120 Ohm termination resistor (supported from CANoe 10.0 SP)
  • I2C master or slave simulation in standard, fast or high-speed mode on two channels with switchable pull-up resistors for clock (SCL) and data (SDA) lines (supported from CANoe 11)
  • Two LVDS channels for sensor communication over higher distances, e.g. for the operation of spatially separated active probes. Additional power supply is provided from the module (supported from CANoe 10.0 SP)
