Compact, powerful datalogger for automotive applications

LinkedIn +

Test and measurement specialist Saelig Company has introduced the x2e Xoraya ML-N4000, which it says is a compact, powerful datalogger for automotive applications, capable of recording data from multiple bus systems simultaneously at data rates of up to 4Gbit/s.

Each logger comes with six slots to enable individual interface configuration of the device for various automotive interface needs. This allows logging from LS-CAN, HS-CAN, CAN FD, FlexRay, RS-232, LIN, Ethernet, 100/1000Base-T1 (OABR), PSI5 and analog signals. Support for other bus systems is also possible. The ML-N4000 provides flexible configuration choices, allowing it to be assembled or retrofitted according to varying customer requirements. The unit’s modular construction enables the datalogger to be adapted to varying test conditions and ever-changing project needs.

All data is logged with a central timestamp offering 100ns resolution and saved either on the internal SSD or transferred via Ethernet to an external computer system or Xoraya external storage unit. A built-in supercapacitor unit bridges any power fluctuations and provides the ability to safely shut down the logger during power failures. The datalogger supports x2e’s own Distributed Logging Network (DLN) as well as the Probe Logger Protocol (PLP) to adapt different probes to the logger.

To increase the logger’s power, the built-in Xilinx FPGA and RAM can be exchanged for a more powerful FPGA module. The internal SSD memory can be expanded from the standard 120GB to as large as 1TB. Additional customer-specific solutions are available, ranging from unique cable sets to corresponding custom installation racks for test vehicles. Software provided includes the Logger OS (embedded Linux) with XorayaSuite and XorayaSDK for Microsoft Windows.
