1 1 8N1 (equal to 00)
5 4 3 TTL UART baud rate （ bps ）

UART baud rate can be different
between communication parties

The UART baud rate has nothing
to do with wireless transmission
parameters & won’t affect the
wireless
transmit / receive
features.

Air data rate （ bps ）

The lower the air data rate, the
longer the transmitting distance,
better
anti-interference
performance and longer
transmitting time

The air data rate must keep the
same for both communication
parties.

7 Fixed transmission enabling bit （ similar to MODBUS ）

In fixed transmission mode, the
first three bytes of each user's data
frame can be used as high/low
address and channel. The module
changes its address and channel
when transmit. And it will revert
to original setting after complete
the process.
0 Transparent transmission mode
1 Fixed transmission mode
6 IO drive mode (default 1)

This bit is used to the module
internal pull-up resistor. It also
increases the level’s adaptability
in case of open drain. But in
some cases, it may need external
pull-up resistor.


The transmit & receive module
work in mode 0, whose delay time
is invalid & can be arbitrary value.

The transmitter works in mode 1
