Power and current are nonlinear, and
power efficiency is highest
maximum power.
The current does not decrease in
proportion to the decrease in power.
Actual frequency= 410.125 + CH
*1M
When enabled, the module receives
wireless data and it will follow an
RSSI strength byte after output via
the serial port TXD
.----------------------------------
The module recognizes the first
three bytes of the serial data as:
address high + address low +
channel and takes it as the wireless
transmitting target.
---------------------------------------
After the reply function is enabled, if
the target address is not the module
itself, the module will forward it
once.
In order to prevent data return-back,
it is recommended to use it in
conjunction with the fixed point
mode. That is: the target address is
different from the source address.
-----------------------------------
When enabled, wireless data will be
monitored before it is transmitted,
which can avoid interference to a
certain extent, but may cause data
delay.
Only valid in Mode 1.
After the WOR receiver receives the
wireless data and outputs it through
the serial port, it will wait for
1000ms before entering the WOR
again. Users can input the serial port
data and return it via the wireless
during this period. Each serial byte
will be refreshed for 1000ms. Users
must transmit the first byte within
1000ms.
--------------------------------------
Only valid in Mode 1.
