Freematics OBD-II Emulator is a vehicle OBD-II port emulating device in a 12x8x3cm enclosure with a standard 16-pin female OBD-II port, 9 rotating knobs, 3 switches, a USB port, a DC 12V power input port and a power button. The OBD-II female port is identical to the one in a real car. OBD-II compliant devices plug into the emulator, get powered and work as if plugged into OBD-II port of a real car. The emulator is practically useful and cost effective in OBD-II application development by saving the time and fuel for debugging and testing programs with real cars.

 

Features

  • Emulating OBD-II port identical to one in a real car
  • Responding to standard OBD-II PIDs polls and VIN request
  • Switching among supported vehicle data bus by physical switches and USB serial terminal
  • Value of PIDs controllable by physical knobs
  • Providing both power and data for OBD-II compliant devices

Following protocols are supported:

  • CAN 500Kbps/11bit
  • CAN 250Kbps/11bit
  • CAN 500Kbps/29bit
  • CAN 250Kbps/29bit
  • ISO9141-2
  • KWP2000 Fast
  • KWP2000 5Kbps

By default following OBD-II PIDs can be controlled through the 9 knobs:

  • 0104 - Calculated engine load value
  • 010C - Engine RPM
  • 010D - Vehicle speed
  • 0110 - MAF air flow rate
  • 0111 - Throttle position
  • 012F - Fuel level input
  • 010A - Fuel pressure
  • 010B - Intake manifold absolute pressure
  • 015E - Engine fuel rate

Besides above OBD-II PIDs, other standard OBD-II PIDs are also accessible with a fixed value. The value of PID 011F (Run time since engine start) changes along with real time. VIN is also accessible.

To change additional OBD-II PIDs, or set DTC (Diagnostic Trouble Codes) and VIN (Vehicle Identification Number), check out the Freematics OBD-II Emulator MK2.

 

Configuration

Freematics OBD-II emulator can be configured by the 3 switches or USB serial command line interface.

The baudrate of CAN bus protocol simulation can be configured by the 250K/500K switch. The CAN ID switch can toggle between 29-bit and 11-bit CAN ID. The type of KWP2000 protocol (ISO9141-2 or ISO14230) can be altered by the thrid switch.

The simulated protocol can also be altered via the serial command line interface. To do this, connect the emulator to a computer with a USB cable, open serial interface (with any serial terminal program) with baudrate of 115200bps, and then enter one of the following commands followed by character 0x0D (\r).

  • CAN_11B_500K
  • CAN_29B_500K
  • CAN_11B_250K
  • CAN_29B_250K
  • KWP2000_FAST
  • KWP2000_5BPS
  • ISO9141_2
