Stand-Alone Operation with Non-plus Editions
The Non-plus editions of the Au J1708/J1587 Simulator are designed for standalone operation, eliminating the need for a personal computer. These devices can independently generate a full spectrum of J1708/J1587 signals, controlled through three intuitive push buttons. This makes them incredibly convenient for quick tests and demonstrations in various environments.
Enhanced Control with Plus Editions
Plus Editions build upon the functionality of the Non-plus versions by incorporating remote terminal GUI display and control capabilities. While retaining the ability to operate independently, the Plus editions offer an optional PC-based “Remote Terminal GUI.” This software connects to the simulator via serial communication, providing a user-friendly interface to monitor simulator information, adjust settings, perform license upgrades, and visualize simulated J1708 signals on a computer screen.
Script Control for Advanced Simulation with Script Editions
Script Editions represent the most advanced tier, adding script control capabilities to the already feature-rich Plus Editions.
- Engine Basic Script Edition: Includes all features of the Engine Basic Plus Edition, enhanced with script control.
- Engine Premium Script Edition: Incorporates all functionalities of the Engine Premium Plus Edition, along with script control.
- Vehicle Platinum Script Edition: Combines all features of the Vehicle Platinum Plus Edition with script control.
Script control enables users to precisely set six key parameters—Engine RPM, Vehicle speed, VIN, Battery voltage, Engine hour, and Total vehicle distance—within the SAE-J1708 specification limits. Users can generate and execute pre-saved script segments, introducing delays, repetitions, and even white noise for more realistic simulations. The script control also manages CAN bus on/off switching. Notably, Engine hour and Total vehicle distance parameters accumulate over time, mirroring real-world vehicle behavior.
Visualizing a Typical J1708 Network Topology
Understanding how the Au J1708/J1587 Simulator integrates into a network is crucial. A typical J1708 network topology with a simulator is depicted below:
