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-400ER 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.

high-speed CAN, a 120 ohm terminal resistor needs to be connected to the network
terminal node to eliminate signal reflection on the bus and avoid signal distortion. Figure
3.2 shows the high-speed CAN network topology.
The device has a built-in 120 ohm terminal resistance, which can be configured to
turn on or off by using the configuration tool CANDTU. For operation details, see 4.3.1.
Note: The bus communication distance and communication rate are related to the
field application and can be designed according to the actual application and related
standards. The CAN-Bus cable can use ordinary twisted pair, shielded twisted pair or
standard bus communication cable. In long-distance communication, the terminal
resistance value needs to be selected according to the communication distance, cable
impedance and number of nodes.
3.6 Ethernet Interface
The device provides one Ethernet interface. The physical form of the interface is RJ45, which realizes the
communication between the device and the PC. The interface 100/1000M specification, interface
schematic diagram and signal definition are shown in Table 3.9.

RJ45 terminal
3.7 SD Card Interface
The device provides one SD card interface, which supports a maximum of 64 GB SD
memory card for storing CAN bus message data. The interface adopts a self-locking card
slot, and the SD card can be locked after the card is inserted according to the direction of
the casing logo to prevent accidental falling off during use. When pulling out the card, just
push it inwards to eject the SD card.
The SD card uses the EXT4 file system. Connecting the SD card through a card
reader cannot directly view the SD card data in the Windows system. You need to install a
tool plug-in that supports the EXT file system (for example, Ext2Fsd).
The device data can be obtained directly in the window by using the method in
section 4.3.5.
Note: Do not forcibly pull out the card during the device operation; otherwise, it
may cause data loss or damage to the memory card and device exceptions! If
necessary, after powering off the device, open the SD card slot cover, push in
gently and eject the SD card.
