FAQ
Question : What is CP-CANFD?
Answer : CAN FD (Controller Area Network Flexible Data-rate) is an enhanced version of the original CAN (Controller Area Network) protocol. It is designed to provide higher data rates and support increased data payload sizes, making it more suitable for modern, data-intensive applications.
Our CP-CANFD supports both CAN FD and Classical CAN protocols.
Advantages of CANFD Over Classical CAN Bus:
- Increased Data Rate: CAN FD supports data rates of up to 8 Mbps, allowing for a significantly higher bit rate during the data phase of the message, compared to the 1 Mbps maximum in classical CAN.
- Larger Data Payload: CAN FD supports data payloads of up to 64 bytes per frame, a substantial increase from the 8-byte limit in classical CAN.
- Backward Compatibility: CAN FD is designed to be backward compatible with classical CAN, meaning CAN FD controllers can communicate with classical CAN controllers, allowing for a mixed network.
- Improved Efficiency: With the ability to transmit more data in a single frame at a higher data rate, CAN FD enhances overall network efficiency, reducing bus load and increasing available bandwidth.
Question : Is termination essential for CAN FD (Controller Area Network Flexible Data-rate)?
Answer :Yes, termination is crucial for a CAN FD network. Proper termination is necessary to maintain the integrity of communication on the CAN bus, including CAN FD networks. This involves placing termination resistors at both ends of the bus to ensure signal integrity and reduce reflections. Our CP-CANFD adapters are equipped with built-in 120 Ohm termination resistors on each channel, with a selectable jumper providing flexibility for the user. For more details, please refer to the datasheet.
Question : How can I know the status of CP-CANFD adapter?
Answer :The CP-CANFD adapter includes status LEDs on the top panel for each CAN FD port, providing clear indications of data transfer, error status, and power. The green LED shows CAN bus data activity, while the red LED indicates a CAN bus error. For more detailed information, please refer to the datasheet.
