Frequency range and channels
5.3.
Model
E62-DTU (433D20)
★
Note: In the same area when mu ltip le data transceivers are commun icating 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.
Transmit power level
5.4.
Model
E62-DTU (433D20)
★ 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 maximu m transmit power.
Current parameters
5.5.
Model
E62-DTU (433D20)
★ Note: It is recommended to retain more than 50% o f the current marg in when selecting the power supply, which will
help the data transceiver to work steadily for a long time.

★ Note:
1. When the receiving data is more than a single packet capacity, the beyond part will be automat ically assigned
to the second transmission until it is completed;
2. The data transceiver cannot receive data which is more than the buffer capacity;
