CAN/LIN Line monitor

LE-170SA

●Supports CAN and LIN
●4.3 inch color touch screen
●Real-time display of communication data
●Supports USB flash as strage device
●Handheld, 5 hours work by AA size Ni-MH batter

LE-170SA is a compact hand-held size line monitor for CAN/LIN. It has a touch screen and can be control as for smartfones. It has 1 CAN channel and 1 LIN channel and it can monitor both CAN and LIN communication thus monitoring of the network which has both CAN and LIN is available. The monitor function can diplay the communication data in real-time while saving it. The simulation function can send/receive the test data instead of the original communication partner. The ID filtering and trigger function make your development/evaluation more efficient. It also can measure 4 external signals as degital signals or analog signals while monitoring the communication data. It is light (300g) and convenient for field testing. The line monitor is useful for not only development but also maintenance.

Supports CAN and LIN

For CAN connect using the attached Dsub 9-pin monitor cable with a CAN bus. For LIN connect using the attached 10-pin external I/O cable or optional 5-wire prove cable (LE-5LS) with a LIN bus.

Line Monitor Function

It monitors and displays in real time the communication frame, send/receive time (time stamp), external analog input signal, and external trigger signal condition while saving them. The saved data on the capture memory can be checked by scrolling display or search function.



It saves the logic and analog value of 4 external input. Measured data display and external analog display can be exchanged by touching the screen.

< Analog display of external input >

It can search the specified data from the data in capture memory. It also can count how much the data matches the condition. The serach condition can be set from trigger match, errors of LIN, communication data of the specific condition, external input, and timestamp range.

< Seach condition setting >

Simulation Function

It can send 16 types of pre-registerd frame manually. It also can sweep (change) a part of send data by specified condition and can simulate the change of value. For LIN master mode and slave mode can are selectable.

Auto Save Function

By the auto save function, you can automatically save communication data to a USB memory continuously for a long time. Since it is saved in multiple communication log files of the specified size (# nnnnnnn.DT: n is a serial number in the order of saving), you can find the communication logs before and after the failure by the time stamp of the files in the time zone when the communication failure occurred.

: Available by the firmware Ver.1.01 or later.


AUTO RUN automatic measurement function - convenient for unmanned measurement

By specifying the date and time of the start and end of the measurement, the specified period can be automatically measured. Since the measurement can be started in conjunction with the power-on (start of USB bus power supply) from the power-off state of this device, you can start the measurement on the power-on of the equipment and finish the measurement at the specified date and time.

: Available by the firmware Ver.1.01 or later.

The Trigger Function Can Be Synchronized with External Signals.

It can control the timer/counter or send a CAN frame by the trigger such as communication error, unusual signal from an external device, and a specified factor event.

Auto Backup Function

By the function the line monitor backups the latest about 30Kbyte data to the internal SRAM capture memory (battery powered) or all the data to a external USB memory connected with the line monitor.

Continuously Runs for 5 Hours by Batteries

It can continuously run for 5 hours by the attached two Ni-MH batteries. You can use alkaline battery too.

USB Memory Supported

The measured data and configuration settings can be stored into a USB flash. You can save the former and the latter part of the target data by using the trigger setting. Also by making the Auto Backup function valid, it automatically saves all the measured data to a USB flash when it finishes the measurement.
