SIMJ1708-002: Au SAE J1708 / J1587 Simulator Engine Basic (Non-plus) Edition

SIMJ1708-006: Au SAE J1708 / J1587 Simulator Engine Basic Plus Edition

The Au J1708 simulator Engine Basic editions generate 18 most frequently used engine parameters in SAE J1708 / J1587 format. PC remote terminal software is included for the Plus edition.



Optional PC remote terminal software:

Typical J1708 network topology:


Au SAE J1708 / J1587 Simulator engine basic editions are capable of simulating 18 most frequently used J1708 / J1587 engine parameters.

As the non-pus editions, the plus editions can still work independently (without a PC). The optional remote terminal software can be used to control and display simulated J1708/J1587 data.

Au J1708 Simulator Engine Basic Plus Ed. = Engine Basic non-plus Ed. + Remote Terminal on PC

These device are very easy to use. No decent knowledge or experience of J1708/J1587 is required to operate them. Simply connect the devices to a J1708 network, power up, you are good to go.

Au SAE J1708 / J1587 Simulator Engine Basic Editions are designed to simulate all 6 parameters supported by value package edition plus 12 more Basic Engine parameters on a J1708 / J1587 network (18 parameters altogether):

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 ("Plus" edition only): Display simulated J1708 signals on a computer screen.
• All push button control functions are available on PC "Remote Terminal" software ("Plus" editions only)
• Easy in-field license upgrade feature
• In-field firmware update capability
• Annual support and minor upgrade services are available (SVS-SIM-J1708 )
