Stack Multi-Function Recorder -
MFR System Powerful, scalable single module data acquisition solution.
The Stack ST8956 Multi-Function Recorder (MFR) can monitor a range of values, known as performance parameters, needed for effective car and driver management in most competitive situations.
The system consists of a 14 input sensor module with a built-in 32 MB data recorder. All of the sensors may be recorded at rates up to 200 Hz. Data recording can be configured to start when a parameter, eg, Engine Speed, rises above a preset value.
The recorder can hold 30 Runs and those runs can be downloaded to your PC using the Stack DataPro software.
The MFR can be used to drive a configurable remote Liquid Crystal Display (LCD), ST8995-2, in real-time.
The Multi-Function Recorder can record up to 45 channels across the Stack CAN network as a whole, with a network capacity of up to 4000 samples per second.
A WiFi/WLAN data download option is available on the ST8956-W version of the MFR.
Stack's Multi-Function (Data) Recording system combines the proven benefits of integrated STACK Display systems with the latest STACK data-logging technology. The module has the basic functions available out of the box: the advanced functions can be made operational simply by PIN code activation.
