PC-connectable protocol analyzer
/ Data logger


  • ●2-way operation of PC-connected protocol analyzer / logger
  • ●2-channel measurement by combination of CAN and LIN
  • ●pass / cut filter and powerful trigger function makes the analysis more efficient
  • ●Can check the log file without stopping the logging
  • ●Robust design to withstand use in harsh field environments

*1:Only “Hr:Min:Sec”, “Min:Sec:x1ms”is available on Analog mode.

*2:Only SDHC card sold by LINEEYE is supported.

*3:Wi-Fi function is available only in Japan, USA, Canada, and EU nations where the product is needed to be compliant with RE directive (2014/53/EU). The Wi-Fi function of this product is set to invalid depending on the country where it is shipped. Please contact LINEEYE for the detail.

*4:AC adapter is sold separately. In the Remote mode (with PC), the analyzer runs by the USB bus power. In the Logger mode (PC-less), you need to have the optional AC adapter (6A-181WP09) or use the proper external power.
*5:Power supply from connector 1pin consumes abou 30mA even when the power is turned off. If you want to save the power consumption use OBD2-DB25C-1 cable etc.
