The serial port baud rate of a wireless data station at work，1200bps～115200bps
Support 8N1:no check ；8E1:even-check；8O1:odd-check；Both are 8-bit data bits and 1-bit stop bits.
Wireless communication rate, also known as air baud rate air rate high, data transmission speed, transmission
of the same data time delay is small, but the transmission distance will become shorter.
In order to ensure the working efficiency, it is recommended to use the maximum power. If the transmitted
power is reduced, the communication distance will become shorter and the required current will be reduced
The lost or interfered data can be partially corrected by complex encoding, which can improve the equivalent
receiving sensitivity by about 3dBm. Turning off this function can reduce the communication delay.
Transparent transmission, and send-as-received fixed points: data is sent at fixed points according to the
format
There is no direct relationship with the communication delay. If the customer needs low-power applications,
this option shall be adjusted as required. In the power-saving mode, the longer the wake-up time, the lower
the power consumption of the receiving end, and the greater the communication delay.
By default, select the internal TTL signal drive mode。
Internal address of wireless data station, stations with the same address as those independent of Modbus
address can communicate with each other. This feature can be used to realize software filtering grouping
input range :0~65535, decimal number.
It is equivalent to the working frequency of the wireless data transmission station. Each channel corresponds
to its different working frequency. Theoretically, different frequency channels cannot communicate with
each other. If there are multiple groups of wireless data stations in the same area, the communication
frequency interval is suggested to be 2~5MHz.
