Hello, I a QJ71C24N-R2 QJ71C24N-R2, QJ71C24N-R2 a-channel and two-channel switch settings are the same, but the data read back a second channel, don't know how to thank your support!

Serial ince communication module communication receives in two ways: 1 receive 2, fixed-length, ending codereceives. Fixed-length received, number of external devices send data must be consistent with the defined length of the received data; end of code received, send data to external devices must have the 0D0A at the end of (the default) end code.
