IOLITE LX
Embedded Data Acquisition System AND DATA LOGGER

Embedded DAQ
With Low-power ARM Processor and Linux OS

For the first time in history, the Dewesoft device is hosting an embedded low-power ARM processor. And what a processor it is...

Borrowed from cutting-edge technology of mobile devices, the integrated ARM CPU can do powerful things, and all this with very low power consumption.

The ARM processor is running brand new Dewesoft RT data acquisition software on Linux OS. The combination of Linux OS, ARM CPU technology, and Dewesoft RT makes IOLITE LX an incredibly flexible device with usages ranging from stand-alone data logging applications, real-time control systems, or just a signal conditioning system with cloud or Industry 4.0 connectivity. Possibilities are unlimited, and we have only just begun!

IOLITE LX is getting constant free software and firmware updates enabling new features. As always we will be listening to customers' needs and we will steer our R&D roadmap to integrate these needs. IOLITE LX is more than just a standard data acquisition system. It is a platform that will evolve and grow!

Integrated Data Storage for Stand-Alone Data Logging Applications

IOLITE LX has an internal 32 GB of data storage. In addition to that, we have included a storage expansion slot that supports up to 1 TB standard SD cards and a USB Type-C port for external drives. This transforms IOLITE LX into a stand-alone data logger, where data can be logged either into an internal or external connected SD card. 

It is able to store any number of channels with a maximum sampling rate making it the perfect instrument for embedded data acquisition.

Stored data files can be reviewed and analyzed by anyone using the included powerful and award-winning DewesoftX data acquisition and signal processing software.

Great Connectivity With Standard Interfaces and Protocols

The acquired data is available to other data systems or controllers using standard data protocols included with IOLITE LX:

• EtherCAT is an industry-standard for real-time control applications. IOLITE LX uses two EtherCAT buses in parallel. When it is switched to external master mode, the primary EtherCAT bus is used for full speed buffered data acquisition to a computer while the secondary bus is mainly used to serve data in real-time to any 3rd party control system.
• OPC UA is a leading standard for Industry 4.0 applications. The data can be served to SCADA, ERPs, and MES systems as well as mobile clients in real-time.
• CAN and XCP on Ethernet provide the data to ECU calibration software such as ETAS INCA or Vector CANape in real-time with minimum latency.
