Command word: the command word in the response frame is the same as that in the command frame,
namely 0x02.
Data length: 1 byte, the number of data bytes in the data field within the frame, which is fixed at 4 (i.e.
0x04).
Data field: 4 bytes, product hardware identification information.
Check word: 1 byte, which is exclusive OR of all previous bytes.
2. Verify product hardware identification response frame
After receiving the command frame for verifying product hardware identification, TD5(3)USPCAN will
identify the hardware identification in the command frame with its own hardware identification.
Match the knowledge, and return the comparison result to the main control terminal through the
response frame. The format of the response frame for verifying product hardware identification is shown in
Table 4.9.
