Key Features

ALL-IN-ONE INDICATING SYSTEMS

Key features	Description
GigaBit Ethernet	All AVL indicating systems are equipped with a GigaBit Ethernet interface for the PC communication. Due to this interface technology raw data can be streamed to the PC's memory, which enables very long measurement durations and various measurement modes.
OHI interface	With the operating and control software AVL IndiCom^TM it is possible to transfer cyclic result values to the calibration software INCA. Hence cyclic combustion information can be recorded time-synchronously with other engine characteristics. INCA also assumes the role of master during this operating mode, so that AVL IndiCom^TM is fully remotely controlled.
Standalone Mode	The AVL IndiMicro^TM indicating system is able to operate fully stand-alone. Initially parameterized it is able to calculate cyclic results out of the acquired raw data and make it those results available via CAN out
IFile Format	The IFILE is a specific file format developed for the storage of combustion data. Besides the measured raw data and calculated result values, information about the indicating measurement is stored to enable full traceability. Mistakes in the parameterization can be easy detected.
Real Time CAN	Combustion characteristics are available for other acquisition systems via the built-in realtime CAN output interface. The operating software AVL IndiCom^TM enables the generation of the necessary description file in two different formats (a2l or canDB format)
