Air data rate
Wireless communication rate, also called air baud rate. The air rate is high, the data transmission
speed is fast, and the time delay for transmitting the same data is small, but the transmission distance
will be shortened.
Frequency
channel
The working frequency of the DTU, each channel corresponds to its different working frequency, in
theory, different frequency channels cannot communicate with each other. If there are multiple groups
of wireless data transmission stations in the same area, it is recommended that the communication
frequency be separated by 2~5MHz.
TX power
The output power is the power radiated to the outside. In order to ensure the working efficiency, it is
recommended to use the maximum power. If the transmit power is reduced, the communication
distance will be shortened, and the current consumed will be reduced.
DTU address
The internal address of the DTU has nothing to do with the Modbus address. Only DTU with the
same radio address can communicate with each other. This feature can be used to realize software
filtering and grouping. Input range: 0
～
65535, decimal number.
TX method Transparent transmission
；
Fixed point: send data to fixed point in Hex format
Wake-up time
It is not directly related to the communication delay. If customers need low-power applications, they
need to adjust this option as required. In the power saving mode, the longer the wake-up time, the
lower the power consumption of the receiver, and the greater the communication delay.
