CW-141

CAN-Bus and CCP-Analyzer

The CW-141 makes it possible to study and analyze CAN networks. Designed as a portable, hand-held device in a rugged aluminium housing, it is particularly suitable for mobile use.

Utilizing the CW-141 in combination with its intuitively designed software operated via a touchscreen it is possible to measure and analyze the characteristics of CAN networks including the baud rate, terminating resistor, short-line faults, signal level and CAN data (data and error frames). As a consequence the battery-powered CW-141 makes troubleshooting on CAN buses in the field easier and eliminates the need to use extensive measurement technology or cabling.

In addition to analyzing physical bus parameters and their correct function the CW-141 offers the option at the same time to test remote CCP stations (CAN Calibration Protocol) in the CAN network. For this purpose the communication ID of the respective control unit or station is configured for CCP via an A2L file or entered manually. The CW-141 analyzes the connection to the station and displays the result on the touchscreen display.
