UniCAN3 Data Logger CSM

The UniCAN 3 is a stand-alone data logger. Microcontroller-based CAN bus data loggers of the UniCAN line are very powerful and feature unique properties that are normally found only in larger devices. This is because key functions are implemented directly in the hardware (FPGA). In addition, the CSM file system supports the specific features of cutting-edge ATA flash-memory cards in terms of fast data storage rates and maximum data security.

System Features
Fail-safe data acquisition
The firmware detects interruptions to the power supply and the removal of the CF card during data recording. No data recorded up to this time is lost. Data recording restarts automatically as soon as the card is inserted again and the supply voltage restored.

Simultaneous acquisition
CAN messages and signals, each up to a maximum of eight separate groups, can be recorded in parallel. Each group has individual trigger and filter criteria and can be used as linear- or ring buffers.

Trigger- and filter criteria
Wide trigger criteria and pre- and post-trigger ranges can be defined per channel/message group. As the capacity of the CF card is the only limit to the size of a pre-trigger, the occurrence of a trigger event can practically contain any amount of trigger data. Edge, gate and flip-flop trigger modes are available.

Optimized memory access to CF cards
Contrary to data loggers with standard file systems, the write access of a UniCAN 3 logger to a memory card is not impaired by the increased segmentation of the memory device. The data is compressed during recording.

Quick start-up
Data recording starts approximately 600 ms after “power on”. The logger stands out for its very low power consumption in stand-by mode.

Start delay
A delay between ignition and the start of data recording can be defined.

Remote data transmission
Data can be transmitted via UMTS/GPRS/ CDMA modem while data recording continues without interruption. Measurement data can be read directly from the CF card or remotely via modem/FTP server (data formats are, for example: MDF, ASCII). For maximum data security, the data transmission is binary.

Data transmission modes
Data transmission can take place after “ignition off” or according to a pre-defined time, e.g. every hour, while the data recording process continues to run.

Data integrity and data security
If the internet is used for data transmission, data integrity can be ensured by using the ftp command XCRC. SSH2 provides protection against data theft and data corruption.

UniCAN 3 Professional Tools
This package includes easy to operate software tools for configuration, fleet- and measurement data management on local Windows computers. Furthermore, CSM offers data processing software for automated conversion and pre-processing of measurement data on server
structures.
