CANDTU-400EWGR
CAN Bus Message Records and Wireless Data Transmission Equipment Series Products
1. Product Introduction
1.1 Product Overview
It mainly includes: product introduction (overview), product pictures (function
instructions may not be provided), and a detailed list of functions.
In the CAN bus troubleshooting, the biggest difficulty is occasional faults. This makes
engineers or even CAN experts unable to accurately identify the fault cause. For example,
the pitch system of the wind turbine had a CAN data transmission interruption in 72 hours;
the dashboard of a new energy vehicle appeared "blank" once during a 10,000 km drive,
but this could not reoccur; the high-speed train experienced an emergency deceleration
due to abnormal CAN communication during a 2,000 km journey. These occasional
CANFD communication exceptions have frightened engineers like time bombs. If one
CAN bus data recorder is installed on an occasion prone to faults, it is equivalent to a
"black box" to record CAN data, which helps analyze the fault cause.
Guangzhou ZLG Electronics Co., Ltd., as a leading manufacturer of the domestic
CAN bus, has developed CANDTU series products for troubleshooting CAN buses, which
can record CAN messages offline. It can easily complete the message recording and
on-site monitoring of applications such as vehicles, ships, elevators, wind turbines, and
construction machinery.
CANDTU-400 series products are 4-channel CAN bus data recorders with storage,
which can run independently from PC and store CAN message data for a long time, which
helps users analyze and troubleshoot. The recorder can transfer the recorded data to a
PC via an SD memory card on the Ethernet. After format conversion of the raw data, users
can carry out offline analysis and evaluation of the recorded data by using CANoe and
CANScope.
