Smart Sensor Simulator 2 Kit

$5,850.00

The Smart Sensor Simulator 2 is a universally compatible device that emulates the electronic systems of a truck. This “truck-in-a-box” technology enables investigators to retrieve data out of electronic control units (ECUs) from damaged vehicles and perform a forensically sound bench-top download. The SSS2 can provide a fault-free environment for a forensically neutral download of the data contained in an ECU. The SSS2 is adjustable by the user with our Smart Sensor Simulator Interface program so a single SSS2 can provide solutions across the wide array of ECUs found on the road.

Definitions and Capabilities:

CAN – Controller Area Network up to 1M bits/sec

LIN – Local Interconnect Network. This is programmed to simulate the shifter lever on Freightliners with an automated transmission.

PWM – Pulse Width Modulated with adjustable frequency and duty cycle. These are 0 to 5V square wave signals.

Digital Potentiometers

The digital potentiometers are 12V tolerant devices with independent terminal connection control. A potentiometer has three terminals: Terminal A, the Wiper, and Terminal B connected to ground. The potentiometer is rated to have a resistance from Terminal A to Terminal B. The wiper picks off from along the resistor string. The terminals can be configured to open and close independently. This gives you the ability to connect the potentiometer as a voltage divider, resistance to ground, or resistance to a high source. The terminals are connected by selecting the checkboxes on the SSS Interface under the Digital Potentiometers tab.

Digital potentiometers can simulate signals that are used for

  • Temperature Sensors
  • Pressure Sensors
  • Analog Accelerator Pedals
  • Actuator Presence (i.e. the presence of an actuator)

The digital potentiometers used in the SSS2 are the MCP41HV51  and MCP45HV51. The digital potentiometers have a limit such that the wiper plus the terminal is between 250 to 300 ohms.

Analog Output

Analog outputs generate signals from 0 to 5 V. The signal is generated by a Digital to Analog Converter (TI DAC7678) and buffered with an op-amp. Each signal is capable of sourcing 25 mA. 

Analog Outputs can simulate signals for:

  • Pressure Sensors
  • Switches to ground (by setting the output voltage to 0)

Analog outputs are similar to a voltage divider when examining the signal with a meter. However, voltage dividers based on a potentiometer sink current and analog outputs can both sink and source current.

Pulse Width Modulated Output

Pulse width modulated outputs are square waves from zero to +5V that have an adjustable frequency and duty cycle. These signals can be used to simulate analog values by adjusting the duty cycle. In other words, a voltmeter will read between 0 and 5v based on the duty cycle. A duty cycle of 0 means the output is driven to ground through an op-amp. A 100% duty cycle means the signal is always on at +5v. The frequency can be set from 0 to 5000 Hz. 

Pulse width modulated signals are the only way to simulate throttle position sensors for some ECUs, like Caterpillar and PACCAR MX.

These signals can also be used to generate speed signals for researching event data recorder capabilities.

Not all channels have independent frequency settings. The PWM1 and PWM2 signals have a common frequency that can only go as low as 245 Hz. PWM3 and PWM4 share the same frequency. PWM5 and PWM6 share the same frequency. The output of PWM 3 shares the pinout for a switched +12V supply and has a 10uF capacitor to ground. This capacitor acts like a low-pass filter, so high frequency values on PWM3 tend to be averaged out and do not show the switching behavior of the other PWM signals.

Smart Sensor Simulator Interface

A Graphical User Interface (GUI) to set configurations for the SSS2 to accommodate different ECUs for the entire fleet. This enables you to have just one Smart Sensor Simulator 2 for all your electronic control unit interface needs.

Current Release:

SetupSSS2Interface-1.0.8.exe

SetupSSS2Interface-1.0.8.zip (Try this in case your computer restricts downloading executable files.)

This installer includes a serial driver to communicate with SSS2 from Windows 7 and 8. Windows 10 should already have the driver installed. You may need administrator privileges.

The latest set of SSS2 settings files come bundled with the executable and are also available as a .zip file.

See Release Notes for previous releases, bug fixes, and new features.

Errata

The SSS2-R05 boards have a thin trace on the 12V supply side that can get too warm and fail under heavy loads. To fix this, we need to solder a wire to the board that bridges the thin trace. If you purchased your SSS2 prior to September 30, 2017, then you will want to get this wire added. Please contact Synercon Technologies to arrange this free repair.
