Vector’s GL1000 and GL1010 compact loggers are used to log CAN and LIN data as well as analog measurement data. Messages are saved and evaluated based on the loaded configuration. GL1000 records data communication and supports logging of analog measurement data such as battery voltage as well as measuring internal ECU parameters. Its low current consumption in sleep mode makes it suitable for vehicle testing. The GL1010 is a variant with IP65 degree of protection for applications in harsh environments. Both loggers are equipped for in-vehicle test drives and for use in test fleets. A compact housing simplifies mounting in vehicles, and a 2-GB capacity memory card allows use for long-term recording. Start time is typically 150 ms, and a ring buffer can be used for long-duration or event-driven recordings.
