Versatile automotive data logger captures multiple data streams simultaneously

09-06-2022 | Saelig | Automotive Technologies

Saelig Company, Inc has released the X2E XORAYA Z7 Automotive Datalogger, which simultaneously records data from multiple automotive bus systems. All data is logged with a precise, central timestamp with 100ns resolution and saved on the internal SSD or transferred to an external computer system via Ethernet. Optionally, the logged data may be stored on a XORAYA external storage unit. Currently, logging is implemented for LS-CAN, HS-CAN, CAN FD, FlexRay, RS-232, LIN, Ethernet, MOST25, MOST150, BroadR-Reach (OABR), PSI5 and analog signals, with further bus systems in development. Harman-Becker’s GNLog protocol and the DLT protocol may also be recorded via Ethernet, OABR, and RS-232.

A built-in supercapacitor unit can bridge power fluctuations and shut the data logger down safely if there is a power failure. The operational interfaces are found on the front panel of the XORAYA Z7: connectors, SD card slot, buttons, and LEDs process/bus activity indicators. A four-port Gigabit Ethernet switch is employed for configuration and downloading the logged traces at speeds of up to 800Mbit/s. The recording interfaces are found at the back of the data logger. 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 further slots for plug-in cards enable flexible interface configurations to meet specific customer needs. An add-on board is also offered to provide the data logger with 12 OABR ports. The unit’s modular construction enables it to be quickly and efficiently adapted to multiple test conditions and can be altered to ever-changing project demands.

These data logging systems are flexible and powerful devices and can simultaneously collect various signals, comprising OBD, CAN, analog, and GPS. Created for vehicle test and OEM engineering data acquisition, these devices can capture real-time data from multiple sources, incorporating temperatures, RPM, brake and accelerator settings, GPS data, speed, and more, with no extra instrumentation or user interaction for long periods.

Compact (9.85” x 8.1 x 2.2”) and rugged, the device is specified for operation from -40C to +65C, operating from a 6V to 36V source. In automatic sleep mode, it can wake up by CAN, FlexRay, RS-232, LIN, MOST, PSI5, wakeline, or trigger.
