Parameter

Baud rate

Baud rate when operating 1200bps～115200bps

Parity

8N1:none；8E1: odd；8O1:even；8 data bit，1 stop bit

Wireless communication rate, also called air baud rate. The air rate is high, the data transmission

Air data rate

speed is fast, and the time delay for transmitting the same data is small, but the transmission distance

will be shortened.

The output power is the power radiated to the outside. In order to ensure the working efficiency, it is

TX power

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.

The lost or interfered data can be partially corrected through a complex coding method, which can

FEC

improve the equivalent receiving sensitivity by about 3dBm. Turning this feature off can reduce

communication delays.

TX method

Transparent transmission；Fixed point: send data to fixed point in Hex format

It is not directly related to the communication delay. If customers need low-power applications, they

Wake-up time

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.

IO MODE

NONE

The internal address of the DTU has nothing to do with the Modbus address. Only DTU with the

DTU address

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.

The working frequency of the DTU, each channel corresponds to its different working frequency, in

Frequency

theory, different frequency channels cannot communicate with each other. If there are multiple groups

channel

of wireless data transmission stations in the same area, it is recommended that the communication

frequency be separated by 2~5MHz.
