11 SYSTEM EXTENSIBILITY OTHER SYSTEM CONNECTION: ETHERNET/ ASAM3 AGREEMENT When the engine is tested on test bench, according to the test standards and specifications, system may access certain special equipment. These special systems are often provided by other manufacturers or companies. User may request to integrate the measurement and control data from these instruments on the computer monitor or digital display. Besides, user may demand to have those measured results embedding in the same test report. FC3000 (Engine) Automatic Measurement and Control System can meet all above requirements. Measured data from peripheral instruments can be accessed through cables or various signal format to FC3000 data acquisition system (Digital signal can be directly transmitted to computer). By initialization setting of acquisition module, different forms of signal can be processed as digital signal and transmitted through Ethernet or ASAM3 agreement to display unit and computer terminal. All measured data can be displayed and printed. Emissions equipment and INCA equipment are the typical examples of peripheral instruments. Contact: Page 10

12 OTHER SYSTEM CONNECTION: CAN/ RS485 BUS PROTOCOL POWERLINK Motor Test (Eddy Current Dynamometer) When the engine is tested on test bench, according to the test standards and specifications, system may access certain special equipment, such as FC242 series (Engine) Coolant Temperature Control Device, FC243 series (Engine) Oil Temperature Control Device and other test devices etc. Contact: Page 11
