OBDII Interface (USB)

OBDII interface for engine data recording

This OBDII interface allows you to quickly and reliably read the engine speed (RPM) directly from the vehicle bus.
The solution is particularly useful in diesel engines where the capacitive and inductive terminals are not able to read the engine speed correctly.

Functions and Features

• USB interface with 6 meter cable
  – data transmission in serial form along the entire length of the cable
  – conversion to USB is carried out only at the end of the cable
  – high immunity to electromagnetic interference

• Full integration with SportDyno software (version 3.8.3 or later)
  – independent of SP1 / SP3 / SP4 / SP5

• Support all OBDII protocols:

  • SAE J1850 PWM (41.6 kbaud)

  • SAE J1850 VPW (10.4 kbaud)

  • ISO 9141-2 (5-baud initialization, 10.4 kbaud)

  • ISO 14230-4 KWP (5-baud initialization, 10.4 kbaud)

  • ISO 14230-4 KWP (Fast Initialization, 10.4 kbaud)

  • ISO 15765-4 CAN (ID 11-bit, 500 kbaud)

  • ISO 15765-4 CAN (ID 29-bit, 500 kbaud)

  • ISO 15765-4 CAN (ID 11-bit, 250 kbaud)

  • ISO 15765-4 CAN (ID 29-bit, 250 kbaud)

  • SAE J1939 CAN (ID 29-bit, 250 kbaud)

• Power supply from the vehicle installation:

  • 12 V

  • current consumption: 45 mA
