1.0 Overview
ECUsim 5100 is a small, lightweight, benchtop simulator that can be used for
testing and development of OBD devices and software. It supports all legislated
OBD protocols, fixed and user adjustable parameter IDs (PIDs), diagnostic
trouble codes (DTCs), freeze frames, and many other SAE J1979 services.
The unit has five knobs assigned to common PIDs, a “fault event” button, and
indicator lights for power, connection, and MIL (Malfunction Indicator Light).
Physical connection to the scan tool is made through a standard SAE J1962
female connector.
The simulator can accept from one to three plug-in modules (PIMs), each
configured for a different OBD protocol. The user is able to select any one of
the three protocols using a three position switch, or make them active at the
same time.
ECUsim 5100 features a USB connection which can be used to configure the
PIMs and to monitor OBD traffic.

2.0 User Interface
ECUsim 5100 can be used as a stand alone simulator, or in conjunction with a
PC. It features a number of interface elements on both the front and back of
the unit.
2.1 Front Panel
1. Power LED
2. Link LED
The function of this LED depends on the protocol in use:
a. ISO 9141-2 and ISO 14230-4 protocols: the LED is on while at
least one ECU is initialized. The LED dims when an OBD
message is received.
b. J1850 and CAN protocols: the LED blinks when an OBD
message is received.
3. Malfunction Indicator Light
4. Knobs assigned to the five commonly used Mode 1 PIDs.
5. FAULT button
When pressed, the following happens:
a. Set MIL and number of stored DTCs (Mode 1, PID 01)
b. Generate pending, stored, and permanent* DTCs
c. Generate freeze frame data
6. PIM indicators
a. OFF: PIM not present
b. RED: PIM is present, not selected
c. GREEN: PIM is active
*SAE J1979 defines permanent DTCs only for ISO 15765-4 (CAN)

ECUsim™ 5100 User Guide 7
2.2 Back Panel
1. PIM Select switch
2. USB connector
3. Diagnostic Link Connector (DLC)
4. Configuration DIP switch
a. PIM ALL. Down position: makes all three PIMs active at the
same time. Up position: PIM selection is controlled by the PIM
Select switch
b. 5BAUD/FAST. Selects the type of initialization for ISO 14230-4.
Down: 5 baud init, up: fast init.
c. 11/29 BIT. Selects the CAN frame ID type. Down: 11-bit, up:
29-bit.
d. 250K/500K. Selects the CAN baud rate. Down: 250 kbps, up:
500 kbps.
5. Power jack (12 VDC)
Use only the provided power supply to power the simulator.
Using a different power supply may cause permanent damage
which is not covered under the warranty.

8 ECUsim™ 5100 User Guide
3.0 Basic Operation
ECUsim is configured at the factory according to your specifications (number of
PIMs, assigned protocols) and is ready to be used out of the box. For custom
configuration, see Section 5.0, PIM Configuration.
3.1 Setup
To set up the simulator, follow these steps:
1. Use the Configuration DIP switch to set the desired options.
2. Plug the power supply into an available electric outlet.
3. Plug the 12 volt end of the power supply into the power jack of the
simulator.
4. Select the desired PIM using the PIM Select switch. The corresponding
LED on the front panel will turn green.
5. Connect the OBD connector of your OBD tester or OBD interface to
the DLC.
3.2 Using the Simulator
Once the simulator is set up and configured, you can use the PIM Select switch
on the back of the unit, to switch between PIM1, PIM2, and PIM3. When you
switch to a new PIM, two things should happen:
1. The corresponding PIM indicator LED should change from red to
green.
2. The Power, Link, and MIL LEDs will turn on and off in sequence, as the
PIM starts up.
To generate a malfunction event, press the FAULT button.
The Link light should be flashing or dimming as the messages are exchanged
between the tester and the simulator.
For more details, see the respective descriptions in Section 2.1.

ECUsim™ 5100 User Guide 9
4.0 UART Communication
ECUsim 5100 features a USB connection. On a Windows or Linux PC, the drivers
create virtual COM ports which allow communication using any suitable serial
port terminal (e.g., HyperTerminal).
Set PIM ALL switch to OFF
In order to communicate with a PIM, the PIM ALL switch must be
in the “up” (off) position.
4.1 Installing USB Drivers
To communicate with the ECUsim, make sure it is powered on, and connect it
to any available USB port. If the operating system does not find & install the
drivers automatically, you can download them from FTDI’s website.
FTDI Virtual Com Port Drivers
http://www.ftdichip.com/Drivers/VCP.htm
4.2 Terminal Setup
Almost any serial port terminal emulation program can be used to
communicate with the ECUsim. Some of the popular terminals include the
HyperTerminal, RealTerm, and TeraTerm.
The default communication settings are:
Baud rate: 115200 bps
Data bits: 8
Parity: none
Stop bits: 1
Turn off local echo
ECUsim echoes back what you type, so you may want to turn off
local echo to avoid “seeing double.”

RESET Reboot the PIM
SP xSet OBD protocol
MON 0/1
Turn OBD bus monitoring off (0) or on (1). On power up, OBD monitoring is on
by default. Under certain conditions, turning off bus monitoring can decrease
ECU response time.
