RTU mode

In RTU mode, the modbus minimum idle time between frames should be no less

than 3.5 bytes. The checksum adopts CRC-16 method. All data except checksum

itself sent will be counted into the calculation. Please refer to section: CRC Check

for more information. Note that at least 3.5 bytes of modbus idle time should be

kept and the start and end idle time need not be summed up to it.
