Au SAE J1708 Simulator Non-plus editions

Au J1708/J1587 Simulator non-plus editions are stand-alone devices. They can be operated independently without a PC. Full range of J1708/J1587 signals can be generated by controlling 3 push buttons.

Au SAE J1708 Simulator Plus editions

Plus Edition = non-Plus Edition + Remote Terminal GUI Display and Control capabilities

Au J1708 Simulator plus editions have all the functions of non-plus edition, plus PC Remote Terminal program. Like the non-plus editions, all the plus editions can still work independently without a PC. The optional "Remote Terminal GUI" connects Au J1708 Simulator to a PC through serial communication. It displays the simulator information, alters and displays the simulator settings, and performs license upgrading for all editions. It also shows simulated J1708 signals on a computer screen for "Plus" editions and "script" editions.

Au SAE J1708 Simulator Script editions

Script Edition = Plus Edition + Script Control capabilities

  • The Engine Basic Script edition includes all Engine Basic Plus Edition functions, plus script control capabilities
  • The Engine Premium Plus edition includes all Engine Premium PlusEdition functions, plus script control capabilities
  • The Vehicle Platinum Script Edition includes all Vehicle Platinum Plus Edition functions, plus script control capabilities

Script control sets six parameters to any value in the SAE- J1708 specification allowed range: Engine RPM, Vehicle speed, VIN, Battery voltage, Engine hour, Total vehicle distance. It could generate a few frequently used script segments and run a saved script file. The script can be delayed, repeated, with or without white noise. Script control can also switch CAN bus on-off. Engine hour and Total vehicle distance will accumulate over time.

All editions can statically or dynamically simulate the SAE J1708/J1587 data. Two push buttons (UP and DOWN buttons) are used in the static mode to control the data outputs. The dynamic mode will automatically cycling the data in its range. LEDs will indicate the control status. And buzzer sound reflects push button inputs. The buzzer sound can also be disabled.

After a network is physically connected, simply powering up the simulator will get it transmitting operating data on SAE J1708/J1587 network. No software setup and No CAN protocol configuration skill are required.

Static mode will generate steady SAE J1708/J1587 data, Dynamic mode will generate constant-changing SAE J1708/J1587 data automatically.
