DeveLinkSTUDIO™: the all in one tool for integration and calibration activities

This proprietary tool allows the user to calibrate sensors, change product parameters, flash software updates, and introduce parameter tables.

DeveLinkSTUDIO™ can be applied in the initial phases as well as in the diagnosis, analysis and calibration of embedded software. This versatile tool allows both high-frequency and continuous signal capture, and is prepared for communications with USB, CAN, ETHERNET and UART/RS232 protocols.
