E30-433T20S3 User manual
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.
00H-FFH，for 425 ~ 450.5MHz
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.
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 can

transmit the preamble code of the
corresponding time continuously.
When the receiver works in mode 2,

the time means the monitor interval
time(wireless wake-up). Only the
data from transmitter that works in
mode 1 can be received.
