New datalogger records simultaneously from multiple sources

LinkedIn +

US-based testing electronics specialist Saelig has introduced the X2E Xoraya Z7 automotive datalogger, which it says can record data from multiple different automotive bus systems simultaneously. All data is logged using a central timestamp with 100ns resolution and either saved on an internal SSD or transferred to an external computer system via Ethernet.

Optionally, logged data can be stored in a Xoraya external storage unit. Logging is currently implemented for LS-CAN, HS-CAN, CAN FD, FlexRay, RS-232, LIN, MOST25, MOST150, Ethernet, BroadR-Reach (OABR), PSI5 and analog signals, with additional bus systems in development. Harman-Becker’s GNLog protocol and the DLT protocol can also be recorded via Ethernet, OABR and RS-232.

A built-in supercapacitor unit bridges power fluctuations and shuts the datalogger down safely in case of power failures. The operational interfaces are on the front panel, including connectors, buttons, SD card slot and LED process/bus activity indicators. A four-port Gigabit Ethernet switch is used for configuration and to download the logged traces at speeds of up to 800Mbit/s. The recording interfaces are at the rear of the datalogger.

Each unit comes equipped with 20 HS-CAN channels (upgradable to CAN FD), eight RS-232 channels, one Dual-FlexRay card and four Gigabit Ethernet ports. Three additional slots for plug-in cards allow flexible interface configurations to suit specific customer requirements. An add-on board is also available to provide the datalogger with 12 OABR ports. The unit’s modular construction allows the Xoraya Z7 datalogger to be quickly and efficiently adapted to varying test conditions and ever-changing project needs.

The Z7 is specified for operation from -40°C to +65°C, operating from a 6-36V source. In automatic sleep mode, it can be woken by CAN, FlexRay, RS-232, LIN, MOST, PSI5, wake line or a trigger signal.
