LE-2500XR: Japanese model (with Japanese manual)
LE-2500XR-E: Abroad model (with English manual)

The LE-2500XR is a standard model of a stand-alone communication protocol analyzer which has a touch panel color display and adopted lithium ion battery while inheriting all the functions of the conventional model LE-2500/LE-2500R which have the monitor function, simulation function, and bit error rate test function necessary for communication analysis test.
Visualization of signal status and error data on the line monitor display is dramatically improved by colorizing the display. With the touch panel and the physical key switch, you can optimize the use of them - for example, swiping of the touch screen for display of a large amount of communication monitor data and key operation for MANUAL simulation mode (in which communication test data are assigned to the keys and transmission/reception test is executed). In addition, many key operations of the conventional model are inherited as shortcut key operations.
The newly designed housing is significantly smaller and lighter than the conventional model, reducing the burden for maintenance of communication device and trouble shooting of communication systems.
LE-2500XR is a high cost performance product which can be widely used for RS-232C serial communication around PCs, trouble analysis of RS-422/RS-485 lines of FA equipment, embedded development of I2C, SPI and UART devices, and in-vehicle communication test of CAN, LIN etc.
