Freematics OBD-II Emulator – with J1850 PWM–

1.52

Introduction

Freematics OBD-II Emulator – with J1850 PWM is worlds smallest OBD-II emulator with KWP2000, ISO9141 and CAN bus simulation. It provides an 16-pin female OBD-II port which is identical to that of a real car and responds to requests for standard OBD-II PIDs from plugged-in OBD-II compliant device. It emulates up to 6 active vehicle diagnostic trouble code (DTC) as if a real car has when encountering a component malfunction or fault. Request for VIN is also responded and the VIN can be altered.

The emulator connects to PC via USB cable and is operated via an easy-to-use software GUI. Secondary development is possible with serial TTL connector available for connection of interaction with Arduino or other embedded system with source of data (e.g. sensors).

Freematics OBD-II Emulator is practically useful and cost effective for OBD-II related application development on desk. Once extended with external data source, it can even be used to provide an OBD-II port for vehicles that dont have a real one and thus existing OBD-II device/software can also work with the vehicle.

The emulator is controlled by
GUI software
via USB interface. The BLE enabled version provides additional wireless control by iOS device (iPad/iPhone) with our
Freematics Emulator App
.
