Example: 91H, 03H, 00H, 08H, 00H (Reception data)
91H, 03H, 00H, 77H, 00H (Transmission data)
When abnormal data is received, the data is to be inverted and transmitted.
Example: 91H, 03H, 00H, 00H, 6AH (Reception data)
91H, 03H, 00H, 00H, 15H (Transmission data)
When data other than channel data is received and the data is outside of the range, no data
is transmitted.
Example: 91H, 03H, 05H, 00H, 6AH (Reception data)
No response
