FAQs

Consider the CAN or CAN FD standard, number of channels, isolation, communication performance, operating system and secondary development requirements. For CANopen or advanced development applications, a model with corresponding software and development support may be more suitable.

Yes. With supported GCAN USB CAN analyzers, including selected PRO and PRO+ models, GCAN-TOOLS can be used for CANopen development and testing, including functions such as node scanning, NMT, SDO and PDO operations.

GCAN provides GCAN-TOOLS for CAN message transmission, reception, monitoring and analysis. Selected models also support additional CANopen-related functions through the corresponding software.

Yes. Developers can use the provided API, libraries and example code to create customized CAN monitoring, testing, data acquisition and control applications instead of relying only on the standard GCAN software.

GCAN USB CAN analyzers support Windows systems, with selected models and software also supporting Linux. Operating system compatibility depends on the specific analyzer and its corresponding driver and development package.

Depending on the model and software package, GCAN provides development examples for C#, C/C++, LabVIEW, Python, Qt, VB.NET and VB, helping developers build custom CAN applications.

Yes. GCAN provides APIs, development libraries and example programs for supported models, allowing users to integrate CAN communication into their own software and industrial applications.

GCAN offers USB CAN analyzers for different CAN communication requirements, including standard CAN and CAN FD models, with different channel configurations and performance levels.

Yes. Many CAN analyzers provide message filtering and data logging functions. Users can filter CAN IDs, monitor selected messages and record CAN traffic for later analysis, making it easier to diagnose complex or high-traffic CAN networks.

Many CAN analyzers support both message reception and transmission. Users can send individual or periodic CAN frames to test device responses, simulate CAN nodes and verify communication during development and troubleshooting.

CAN communication errors can result from incorrect baud rates, wiring problems, missing termination, excessive bus load, long cable stubs or electrical interference. Check the physical CAN network first, then verify analyzer and device configuration.

Check the CAN baud rate, CANH/CANL wiring, termination, power supply and analyzer channel settings. Also confirm that another CAN node is transmitting data. Incorrect bit rate or wiring is a common cause of missing CAN messages.

Yes. A high-speed CAN bus normally uses two 120Ω termination resistors, one at each physical end of the network. With power removed, a correctly terminated bus typically measures about 60Ω between CANH and CANL.

The CAN baud rate must match the other devices on the CAN network. Common rates include 125 kbit/s, 250 kbit/s, 500 kbit/s and 1 Mbit/s. Incorrect baud rate settings can prevent reliable CAN communication.

A CAN analyzer is mainly used to monitor, test and analyze CAN communication. A CAN gateway connects CAN with another interface or industrial network, such as Ethernet, RS-485, PROFINET or EtherCAT.

A USB CAN analyzer provides a practical connection between a CAN network and a PC. It allows engineers to monitor, transmit, record and test CAN communication without using a PLC or dedicated CAN controller.

A CAN analyzer connects a CAN network to a PC through a USB or other interface. The software displays CAN frames in real time, including CAN ID, data, DLC and timestamp, allowing users to monitor and analyze bus communication.

A CAN bus analyzer is a hardware and software tool used to monitor, transmit, record and analyze CAN bus messages. It helps engineers test CAN networks, troubleshoot communication problems and verify CAN devices during development and commissioning.
