CAN key panel function setting The communication node number and port rate of the CAN keyboard are set by the CAN bus data. When setting the CAN panel, the ID number is fixed to 0x7FF and the data format is as follows:
CAN panel function setting the data format The setting parameter (BCDE) exceeds 10 when setting the port rate is invalid; ID number (BCDE) exceeds 0x7FF when setting the standard frame; invalid ID number (BCDE) exceeds 0x1FFFFFFF when setting the extended frame; and invalid BCDE is not 0 or non-0 xFF when setting the power button function. When the setting of node, port rate parameters and power button function meets the requirements, the
parameters will take effect immediately after the setting. Uploading of the system parameter information
In 1S before the panel is powered on (A1-2 indicator light), the CAN key panel sends the system parameter information through 0x7FE at a baud rate of 250 Kbit/s, the specific format is:: CAN Key-press panel system information
