LINEEYE develops multi-protocol analyzers for measurement/test of 1GbE/PoE and serial communication.

LINEEYE Co., Ltd. develops 4 models of multi-protocol analyzers "LE-8500X / LE-8500XR" which support measurement of 2-channel 1GbE or 1-channel PoE and "LE-8500X-RT / LE-8500XR-RT" which support RS-232C/RS-422/RS-485/TTL measurement and will start selling them one by one.


LE-8500X / LE-8500XR is a handy-type communication-protocol-analyzer equipped with a measurement board that can simultaneously measure and test the power supply status of one PoE (Power over Ethernet) and two lines of Ethernet communication data on a line (from 10BASE-T to 1000BASE-T). It can be widely used for diagnosis and testing of LAN networks and related devices by using its packet monitor function, packet generate (PG) function, statistical analysis function, PoE judgment function, etc. according to your test situation.
LE-8500X-RT / LE-8500XR-RT are successors of the conventional model "LE-8200 series" and take over the communication-analysis function of the models. They are equipped with the measurement board for RS-232C, RS-422/RS-485, and TTL as its standard board instead of the measurement board for 1GbE/PoE. Both models are equipped with a 7-inch wide-color LCD with a touch panel, thus you can check the measurement data immediately on-site without using a personal computer. You can log the data can be automatically saved to a USB flash memory etc. via USB 3.2 (Gen1), thus you can analyze the data in detail after the measurement.
In addition, as the time stamps that are time-corrected with high accuracy by GNSS signals can be added to the monitor data, by checking the time stamps you can compare and analyze the data measured simultaneously at two points for a long period of time to investigate a communication failure. Furthermore, by replacing the standard measurement board with another measurement board (sold as an option), the communication interface to be measured can be expanded later, so they can be widely used from network systems to development testing and maintenance of embedded communication equipment.
