Chapter - 3 Operating Instructions
All editions of Au SAE J1939 Simulator Gen II 1.00A can be operated by just controlling 3 push buttons. It generates
SAE J1939 signals for product developers, testers, operators and manufacturers.
3.1 Power On
Mate the DB9 female connector of a 6-wire cable (Part#: CBL-CAN-485-01) to the BUS side DB9 male connector of
Au SAE J1939 Simulator, connect the Red wire to +12 ~ +14.2V DC power supply, Black wire to ground, Yellow
wire to CAN-H, Green wire to CAN-L. The Power LED on simulator will light up, and the simulator will resume the
last saved operating mode (static mode or dynamic mode).
3.2 Operating Mode (Static/Dynamic)
After power on, Au SAE J1939 Simulator will work in either static mode or dynamic mode.
•Static mode: Au SAE J1939 Simulator Gen II generates steady SAE J1939 signals. In this mode, two push
buttons (Up and Down) can be used to change the data outputs. When no button is pushed, all data will
remain at the last value.
•Dynamic mode: The value of all data will change automatically every second in SAE J1939 defined range
•Switch between dynamic mode and static mode: Press and hold both Menu and Up buttons until a long
beep is heard if buzzer is enabled; or both the "▼0% LED" and "▲100% LED" flip their status (from on to
off or vice versa)
Au SAE J1939 Simulator Gen II equipped with 3 push buttons (Menu, Down, Up) and 9 LEDs (Figure 3-1). Each
LED is named after its function.
Figure 3-1
3.3 Push Button Functions
•Press Menu button:
oMenu button is used to control Warning LED on/off. A single press on Menu button will turn on the
Warning LED if the Warning LED was off, and vice versa.
oThe Menu button function is available only on Engine Premium editions and Vehicle Platinum editions.
For Value Package editions and Engine Basic editions, Menu button is not used. Warning LED will be
constant off.
oIf buzzer is enabled, a short beep will be heard upon a press on the Menu button.
In dynamic mode, the simulator automatically adjusts the control step value by itself. This will generate dynamic
J1939 signals. In static mode, all* simulated SAE J1939 signal will be controlled by the control step value, which is
still able to be manually controlled by the Up and Down buttons.
Note: * The Engine Clock is not controlled by the control step value and push buttons; it runs all by itself just like a real clock.
•Press Down button:
oDown button is used to decrease the values of all J1939 signals. A single press will decrease all data
one step from previous values until they reach the minimum values. ▼0% LED will be triggered on/off.
oIf ▼0% LED is on, press Down button one time, ▼0% LED will be off.
oIf ▼0% LED is off, press Down button one time, ▼0% LED will be on.
o80% LED blinks when control step value equals to 80%,
o60% LED blinks when control step value equals to 60%,
o40% LED blinks when control step value equals to 40%,
o20% LED blinks when control step value equals to 20%,
o▼0% LED blinks when control step equals to 0%,
oIf buzzer is enabled, a short beep will be heard upon a press on Down button.

•Press Up button:
oUp button is used to increase the values of all J1939 signal. A single press will increase all simulated
data one step to next data level until they reach the maximum values, ▲100% LED will be triggered
on or off.
oIf
▲100% LED is on, press Up button one time, ▲100% LED will be off.
oIf
▲100% LED is off, press Up button one time, ▲100% LED will be on.
o20% LED blinks when control step value equals to 20%,
o40% LED blinks when control step value equals to 40%,

•Delay is the time that specify how many seconds to wait before running another script command. If delay time is
not set, all script commands will run once and then remain at those values except for Engine Hour and TVD..
•The input of Engine hour and Total vehicle distance will change their initial values, both Engine Hour and Total
Vehicle Distance will accumulate over time.
4.3.3 Script Syntax for Au J1939 Simulator
•Each line of script end with \r\n,
•All line comments are preceded by a semicolon (;)
•Always use the script commands generated by Au J1939 Simulator Script generator as any other script may not
work properly. For example, the script generated from Au J1708 Simulator will not work for Au J1939 Simulator
and vice versa.
