Overview
Introduction
USB-CAN-B is an industrial high-performance USB-to-CAN adapter, CAN-bus communication interface card, and CAN protocol data analyzer. Integrating dual independent channels with electrical isolation and multiple protection circuits. Supports Windows and Linux systems, and comes with drivers, CANTools-related software, secondary development examples, and tutorials. It can be connected to the PC or industrial control host via a USB port to realize transceiver control, data analysis, collection, and monitoring of the CAN bus network. Compact in size and easy to use, it can be used for learning and debugging of CAN bus, and secondary development and integration into various industrial, power communication, and intelligent control applications that require CAN bus communication.

Working with Windows PC
Driver Installation
Download the USB-CAN-B/FD Windows driver. Connect USB-CAN-B intelligent interface module to the PC with a USB cable correctly. The Windows will then auto-run an installation wizard called "new hardware is found" after the hardware is detected. Select "Install the software automatically (Recommended)".

Directions for Use
Connect the USB interface of the device with the PC via USB.
Run "USB-CAN-B Tool.exe" as shown in the following figure:
1.Title Bar
When the device is turned off, USB-CAN Tool V9.xx will be displayed, where V9.xx represents the current program version number; when a USB-CAN adapter is successfully opened, the model, serial number, firmware version number, and brand name will be appended to the above name.
2.Menu Bar
Most of the functions of this tool are in the menu, and the functions can be realized by clicking the corresponding menu.
3.Sending Setting Section
This section contains the setting information related to CAN information transmission, among which the "ID increment" function is that when sending multi-frame data, the ID value of the next frame of data is 1 greater than the ID value of the previous frame; The sent 8 bytes of data from a 64-bit number according to the byte order from low to high, and each time the data is sent, it is automatically incremented by 1. This function cooperates with the "receive incremental check" function to test the frame loss rate during high-speed transmission. Note: This function is generally used for internal testing and is not recommended for users. When the data length is set to be less than 8 bytes, it will be automatically filled with 0 and filled to 8 bytes.
4.Can Relay
The CAN relay function is configured in the menu "Device Operation" -> "Relay Mode Options". When configured in relay mode, the relay status will be displayed here. If you want to turn off this function, you can close in the menu "Device Operation" -> "Relay Mode Options". Note: After the relay function is enabled, the baud rate and other parameter settings are invalid, but the sending and receiving, and intelligent filtering functions can be used normally.
5.Intelligent Filtering Function
The two channels can be set separately, and the filter is only for reception. After enabling the filtering function, the ID in the filter list or the ID in the ID segment will be displayed and received, and the data outside the filter list will be masked and discarded. With flexible settings for intelligent filtering, any ID or ID segment can be allowed or blocked from being received.
6.Control Button
"Stop sending" - stop the current sending operation; "Send file" - store the sent frame information in a file in a specific format, and send it in the order of the frames stored in the file; "Open CAN reception" - the CAN receive is enabled, otherwise the CAN receiving function is in the "suspended" state, at this time the host computer will no longer display the CAN bus data received by the USBCAN device, but the USBCAN device is still receiving the data on the CAN bus; "Clear" - clear The contents of the current data list; "Real-time storage" - saves the real-time data to a file.
7.Statistics Area
Includes one-way rate and receives incrementing parity error counters for channel 1 and channel 2. "Frame rate R" - receiving rate, unit: fps (frames per second); "frame rate T" - sending rate, unit: fps (frames per second); "Parity error" (internal functions are hidden by default) - —Receive data increment parity error counter, this value is the total number of dropped frames when receiving increment parity.
8. Data list
The list for displaying the data sent and received.
Please refer to the USB-CAN TOOL Debugging Software User Manual documentation for details.
