The USB-CAN Analyzer is a cost-effective high quality and easy to use USB to CAN adapter. Compared with the 50$ or more expensive CAN Bus Analyzer, CAN Bus Tester, or CAN Bus Sniffer, the USB-CAN Analyzer only needs half the price, but it is even more convenient and easy to use. You can just communicate your CAN Bus device with your computer via the USB cable, then this tiny case will work as your can bus analyzer tool, can bus diagnostic tools, or can bus scanner.
We have released a wide variety of CAN BUS devices, this USB-CAN Analyzer can be used with these devices. You can easily import the acquired CAN BUS data to your computer for analysis. With the help of the supporting software, you can use this USB-CAN Analyzer to develop, test, manage, and maintain CAN Bus network, as well as receiving, sending, analyzing CAN data. We will continue to update the software, fix known bugs, and add new features. If you have problems or have good suggestions during use, please leave a message in the FAQ or post to the forum.
You can see an onboard green jumper cap as the following figure shown. When you add this jumper on, a 120Ω terminating resistor will be added to the circuit. Conversely, when you remove the jumper cap, the resistor will not be added into the circuit. Normally, you need to keep this jumper cap because the CAN device under test and the CAN analyzer are at the ends of the CAN network. If you want to know more, please check 120-ohm terminating resistor page from NI.
In the past, our resource was confusing, which have caused a lot of troubles for many customers. We have reorganized the resources and upgraded the software. Now you can find the complete instructions and the latest version of the software, as well as the window and Linux drivers in the document area.
Optimized the conversion protocol, improved conversion efficiency.
Saving the customized settings automatically.
Hex number converts to Decimal number visualized in the software. Decimal number show both value with symbol and without symbol, don’t need to use calculator.
Customized receiving ID, easy to debug.
Visualized CAN bus status. Convenient for analyze CAN Bus problem.
Can be saved as Excel or TXT file.
Receiving data can be refreshed and checked in order.
Integrated TVS Surge Protection
Including 120 ohm matched resistance.
Support CAN2.0A(Standard) and CAN2.0B（Expansion）
CAN baud rate（5K~1M）, customized CAN baud rate.
CAN send and receive data with time tag，can show the receiving data in order，can refresh data easily.
Data can be sent by single frame, multiple frames, manually, regularly, you can even set a certain time to send.
Response to data received from a certain ID.
Can check CAN Bus status manually.
Can set to receive from the wanting ID directly, without setting filtering ID or shield ID.
4 working mode
Standard Mode: CAN communication
Loop Mode: Self-testing, in this mode, the analyzer will send and receive data itself, and also send data to CAN Bus.
Quiet Mode: Only use to monitor CAN Bus without influence.
Loop Quiet Mode: Warm testing
Baud rate of virtual COM port can also be modified, default baud rate over 1M, so don’t need to worry about conversion efficiency.
All customized settings saved automatically.
Easy secondary development，only need to handle 1 command.
Transparent Transition function
Software supports English
Hi there, Please remove the green 120ohm jumper and see if the issue is solved. thanks.
Hi there, thanks for the sharing about the python-can. https://python-can.readthedocs.io/en/master/
The document is at least partially incorrect: the framing bytes 0xaa and 0x55 seem to be swapped. Also the first several 'bytes' do not seem to be bytes, but are instead the bits in the upper half of the next byte. The number of data bytes seems to be contained in the lower 4 bits of the same byte. I have not learned how to set the can speed yet.
This product is made by the third company.We do not have the souce code of firmware.Btw,you can download the software in this page below <Document>
Hi there~ First, please download the newest software in the link below.Then you can set the parameters as follow: BP1 CAN_BS1_6tq ~ BP2 CAN_BS1_5tq ~ Pre F 90.After that, you will get your 33.33Kbps. Regards # https://github.com/SeeedDocument/USB-CAN_Analyzer/tree/master/res/USB-CAN%20software%20and%20drive(v7.10)/Program #
Hi there~ First, please download the newest software in the link below.Then you can set the parameters as follow: BP1 CAN_BS1_3tq ~ BP2 CAN_BS1_2tq ~ Pre F 72.After that, you will get your 83.33Kbps. Regards # https://github.com/SeeedDocument/USB-CAN_Analyzer/tree/master/res/USB-CAN%20software%20and%20drive(v7.10)/Program #
Hi~Sorry for the late reply.We do help bill (The anonymous user,and he send us a email then) with his problem, and it turns out he did not set it right.We will write a more specific wiki to guide you and the other customers.The wiki is coming soon.Regards
Hi there~ This mode is easy to use, please contact our email so that we can help you.# email@example.com # Thanks
Hi there~ I Apologize for the trouble we have caused you.We will write a more specific wiki to guide you and the other customers.The wiki is coming soon.Before that,you can try this : 1.select the Loop back mode/2. check the COM bps.(when you plug into the USB port of the PC,the led flash one for 2000000/two for 1228800/three for 115200/four for 38400/five for 19200/six for 9600 ) By the way,not only 500Kbitps,in fact the max bps is 1M.We also will show you how to change the CAN bps at the wiki. Regards
Byte 0 header: 0xaa
Byte 1 header: 0xc8
Byte 2 CAN ID: 0x02
Byte 3 -11 are 8 bytes of CAN data: 0x00 0x11 0x22 0x33 0x44 0x55 0x66 0x77 0x88
Byte 12, packet end always: 0x55
-Set and start- button send 4 bytes: 0x00 0x00 0x00 0x17
Sir, I did the same test as you do.And it ended up with the right responding,received from ID 11 with 8bytes 00 01 02 03 04 05 06 07.So there sould be some setting erro, please contact our email , so that we can help you to make it right. # firstname.lastname@example.org # regards
Hi there~ The cycle Mode is easy to use. For instance, set the Loop back mode- add the frame you want to send- select Cycle box - click the button Set and Start.Then you will see the frame cycle. And you can download the newest software here # https://github.com/SeeedDocument/USB-CAN_Analyzer/tree/master/res/USB-CAN%20software%20and%20drive(v7.10)/Program # Regards
Hi there~ At first, please download the latest version # https://github.com/SeeedDocument/USB-CAN_Analyzer/tree/master/res/USB-CAN%20software%20and%20drive(v7.10)/Program # Then please refer to the new manual here # https://github.com/SeeedDocument/USB-CAN_Analyzer/raw/master/res/USB-CAN%20software%20and%20drive(v7.10)/USB-CAN%20User%20Manual(v7.10).pdf #.

Hi there, do not need to connect the GND. you can connect the CANH and CANL. thanks.
Enjoy it then, i'm not buying...
See the link under "Resources" above.
This product is made by the third company.We do not have the souce code of firmware.
No,we do not have .dll for C# or C++.
After few days work stable, now it have same problem. When i plug the usb port, two led on, and then off. Now it can send data, but can not receive. I have factory reset as above, but still not work. Can you help me, pls ?
