Parameter Description
Baud rate
The serial port baud rate of a wireless data station at work
，
1200bps
～
115200bps
。
Odd-even check
Support 8N1:no check
；
8E1:even-check
；
8O1:odd-check
；
Both are 8-bit data bits and 1-bit stop bits.
Air data rate
（
bps
）
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.
Transmitting power
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
FEC
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.
Transmission mode
Fixed length transmission: automatic subcontracting in traditional wireless transmission mode, with a
maximum of 77 bytes per packet.
Continuous transmission: unlimited packet length, supporting wireless continuous transmission.
Wake Up Time
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.
