Chapter 3 Operating Instructions
All editions of Au SAE J1939 Simulator (Gen II) 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
Plug in a 4-wire cable (e.g. Au Part#: CBL-CAN-01) to the Au SAE J1939 Simulator (Gen II) DB9 male connector (on
BUS side). When the CBL-CAN-01 cable is used, connect the Red wire to +12 ~ +24V DC power supply, Black wire to
ground, White wire to CAN-H, Green wire to CAN-L. The Power LED on simulator will light up, and simulator will
resume the last saved operating mode (static mode or dynamic mode).
Note: the 4-wire cable (CBL-CAN-01) is color coded as shown in Table 1-2 (Chapter 1) and is ordered separately.
3.2. Operating Modes (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 stay at
the last value.
•Dynamic mode: The value of all data will change automatically 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 the "▲100% LED" flip their status (from on to off or vice
versa)
