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.

Transceiver Length and Sub-packing Mode
Model Buffer Sub-package
E32-DTU (915L30) 512Byte Automatically send 58 bytes per package
★ Note:
1. When the receiving data is more than a single packet capacity, the beyond part will be automatically assigned
to the second transmission until it is completed;
2. The data transceiver cannot receive data which is more than the buffer capacity;
