E90-DTU address translation method：Populate the channel in the E830 with the address and channel in the E90。For example:
The E830 channel is 31, then the E90 parameter sets the channel to 31, and the address is set to 31, as shown below:

6.3 Number of retransmissions

When the DTU receiver does not receive data in the following mode, the transmitter will resend the number of times the data is sent,
which avoids data packet loss, but the more times it is retransmitted, the longer the transmission time will be; the actual number of
transmissions = the number of retransmissions + 1; the range is from 0~10 times, and the default is 2 times.
