XTool M811 CAN FD Protocol Adapter Connector For Diagnostic Tool Fit For GM 2020-2022

Xtool CANFD Adapter is designed for diagnosing ECUs systems of cars meeting with CANFD protocols. It's used with XTOOL's tablets series products. It's high-performance and easy operation. When the user selects the CANFD model, if the current device does not support CANFD communication, the user needs to be prompted to use the CANFD adapter to connect.

The CAN-FD adapter supports 2020 and newer model year vehicles using the Controller Area Network Flexible Data-Rate protocol, and is an extension to the original CAN bus protocol that was specified in ISO 11898-1.

Data rate transmits up to 5 times faster than the original CAN data allowing more data to be sent between modules required on newer vehicles when diagnosing ECUs and programming new modules.

This adapter simply replaces the standard OBD2 Connector on the Xtool tablets' main data cable. No other software or hardware is required, once installed the adapter can be used with existing software and can be interchanged with the standard OBD2 connector.

CAN-FD data frame format
*CAN-FD data frame newly adds EDL bit, BRS bit, ESI bit in the control field, and adopts new DLC encoding method and new CRC algorithm (CRC field is extended to 21 bits)
*According to the length of the data field, different CRCs are used, such as CRC_17 (0-16Bytes), CRC21 (17-64Bytes)
*Does not support remote frames (no RTR bit)

CAN-FD application scenarios
For the conversion of the existing CAN system, the current mainstream has the following rules for compatibility with CAN and CAN-FD:
*Use separate two hardware channels in one system
*Under the unified platform, keep the original CAN processor and improve the CAN transceiver
*When using CAN-FD communication, sleep CAN node

(PAY ATTENTION !!need to connect with XTOOL tablet X100PAD3, EZ400PRO, A80 Pro etc.)
