1. Product Introduction
1.1 Product Overview
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 and perform GPRS and 4G transmission. It can easily
complete the message recording and on-site monitoring of applications such as vehicles,
ships, elevators, wind turbines, and construction machinery.
CANDTU-200UWGR series products are storage-type 2-channel CAN bus data
recorders. The products can run independently from the PC and store CAN message data
for a long time, which facilitates analysis and troubleshooting. The recorder can transfer
the recorded data to a PC via an SD memory card. After format conversion of the raw data,
users can analyze and evaluate the recorded data offline by using CANoe and
CANScope.
CANDTU-200UWGR also supports 4G communication, which can upload the
data on the CAN bus to the specified server. Support GPS/Beidou positioning and
record the device localization real time.
The CANDTU-200UWGR is also a CAN-Bus bus communication device that
complies with USB2.0 high-speed specification protocol and integrates two CAN
interfaces. The PC can be connected to the CAN-Bus network through the USB bus of the
device to realize the data mutual transmission between the PC and the CAN-Bus network.

The switch output interface is a relay output type, and the interior is a relay contact.
The output control circuit is not limited by voltage and polarity, and can be 24 V DC or 220
V AC. Since it is a dry contact output, users need an external power supply to supply
power to alarm devices (such as buzzers). Figure 3.2 shows the connection.

Figure 3. 4 High-speed CAN typical network connection
The CAN bus adopts balanced transmission. ISO11898-2 stipulates: In the
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
3.4 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 4.2.1.
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.
3.3.5 LIN-Bus Interface
The device provides one independent LIN-Bus interface. The physical form of the
interface is a flange terminal. Table 3.9, Table 3.10, and Table 3.11 list the interface
diagrams, signal definitions,

3.4 USB Interface
The device provides one USB interface. The device communicates with the PC over
the USB cable. The interface conforms to the high-speed USB2.0 protocol specification
and can communicate with PCs compliant with USB1.1 and USB2.0 standards. The
physical form of the interface is a Type-B USB port.
3.5 SD Card Interface
The device provides one SD card interface, which can support SD memory cards of a
maximum of 32 GB 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.
Note: Do not forcibly pull out the card when the device is in use. Otherwise, data loss or memory card
damage may occur! If necessary, after pausing the recording by pressing the button (or configuration
tool), gently push in and eject the SD card.. For details about how to pause the recording, see 4.2.22.
3.6 SIM Card Interface
The device provides one SIM card interface, which supports 4G communication
