Parameter
Description
Baud rate
The serial port baud rate when the wireless digital radio is working, 1200bps
～
115200bps.
Parity
Support 8N1: no parity; 8E1: even parity; 8O1: odd parity; both are 8 data bits and 1
stop bit.
Air data rate
Wireless communication rate, also called air data rate.
Frequency
channel
The working frequency of the wireless modem, 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 modem in the
same area, it is recommended that the communication frequency be separated by
2~5MHz.
Transmit
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.
Modem
address
The internal address of the wireless modem has nothing to do with the Modbust
address. Only modem 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.
Transfer
method
Transparent transmission, what you send is what you get. Fixed point: Send data at
fixed point according to the 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.
