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:
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;
6. Operating mode
E34-DTU(2G4H27) has four operating modes, if low power consumption is not required, normal communication is
recommended to configure the data transceiver for the normal mode (mode 0);
The factory default is normal mode (mode 0).
