Note: In the same area when multiple data transceivers are communicating one to one at the same time , it is
recommended to set the channel spacing between each group of data transceivers at 2MHz or more.

Note: The lower the transmit power, the closer the transmission distance, but the working current won’t be
declined in exact proportion , it is recommended to use the maximum transmit power.

Note: The higher the air data rate, the faster the transmission rate, the transmission distance is also closer; when
the rate meets the requirements , the lower air data rate, the better quality.

Note: It is recommended to retain more than 50% of the current margin when selecting the power supply,
which will help the data transceiver to work steadily for a long time.

Sub-packing method
E32-DTU(433L33)-V8
512 byte
Automatically send 58 bytes per packet
★
Note: 1. If the data received by the radio station at a time is larger than the capacity of a single packet, the excess data
will be automatically allocated to the second transmission until the transmission is completed;
2. The data received by the radio at a time cannot be larger than the buffer capacity;
6 Operating mode
There are
four operating modes, if low power consumption is not required, for normal communication it is
