Example 5: Write register using 06 function: output DO2 of 01 ARD3M.The indicating register
address of switch input/output state is 0013H, bit 0-9 corresponds to Di1-10, bit 10 corresponds to
DO6, and bit 11-15 corresponds to DO1-5.
Check data frame
01 06 00 13 10 00 75 CF
Return
data

01 06 00 13 10 00 75 CF
Example 6: Write register with 16 function: output DO2 of 01 ARD2F.The indicating register
address of switch input/output state is 0013H, bit 0-9 corresponds to Di1-10, bit 10 corresponds to
DO6, and bit 11-15 corresponds to DO1-5.
Check data frame
