Au SAE J1708 / J1587 Simulator (plus) edition is a stand-alone device which is capable of simulating the most frequently used J1708 / J1587 engine parameters.

This device can run independently, no PC is required.

As a handy option for new product development and product validation, a PC software (remote Terminal) is also included. The so-called “Remote Terminal” software can remote control the device, and display simulated J1708 signals on a personal computer (PC). This user-friendly GUI (Graphic User Interface) of remote terminal software is useful for new product development and product validation.

This device is designed with assembly line operator and sales person in mind, which makes it very easy to use. No decent knowledge or experience of J1708/J1587 is required to operate this device.

Simply connect the device to a J1708 network, power it up, you are all set.

Au J1708/J1587 Simulator Value Package is designed to simulate the following Message ID and PIDs (parameter identification) on a J1708/J1587 network:
• Message ID: 128 (Engine #1)
• PID list:
* Request Parameter (PID: 0)
* Percent Engine Load (PID: 92)
* Engine Oil Pressure (PID: 100)
* Engine Coolant Temperature (PID: 110)
* Fuel Rate (Instantaneous) (PID: 183)
* Engine Speed (PID: 190)
* Engine Hour **(PID: 247)
(Note: * *On Request per SAE J1587 definition)

• 1 DB9 Male "BUS" Interface: for power supply and J1708 network connection
• 1 RS232 interface: for in-field firmware update, license management and remote control.
• TVS (Transient Voltage Suppressor) protection on J1708 bus
(Note: * Warning LED is not used in Value package editions)

Major Operating Features:
• Smart features: Recall last operating mode at power-on, capable of generating dynamic data, etc.
• Ease of use: Easy-to-operate design with production line operator and sales person in mind. No software setup experience or J1708 protocol configuration skill is required. After a network is physically connected, it will dynamically generate J1708 data when it enters dynamic mode.
• Static mode and dynamic mode:
* Static mode output static J1708 signals. In this mode, signal can be changed manually
* Dynamic mode automatically changes the output value of J1708 signals
* Two modes can be switched easily
• "Remote Terminal" software: Display simulated J1708 signals on a computer screen.
• All push button control functions are available on PC "Remote Terminal" software
• Easy in-field license upgrade feature
• In-field firmware update capability
• Annual support and minor upgrade services are available (SVS-SIM-J1708)
• Custom design is available upon request.
