Transmit Power Level; Current Parameters - Ebyte E90-DTU(433L30E) User Manual

E90-DTU(Ethernet) wireless transceiver

3.4 Transmit power level

Model
E90-DTU(433L30E)
E90-DTU(433C30E)
E90-DTU(433N30E)
★ Note: 1. 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.
2. In order to guarantee the transmitting efficiency of, the factory default is the maximum transmitting power.
3.5 Air data rate
Model
E90-DTU(433L30E)
E90-DTU(433C30E)
E90-DTU(433N30E)
★ 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 .

3.6 Current parameters

Model
E90-DTU(433L30E)
E90-DTU(433C30E)
E90-DTU(433N30E)
★ 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.
3.7 Transceiver Length and Sub-packing Mode
Model
E90-DTU(433L30E)
E90-DTU(433C30E)
E90-DTU(433N30E)
★ Note: 1. When the receiving data is more than a single packet capacity (100 bytes), the beyond part will be
automatically assigned to the second transmission until it is completed;
2. The data transceiver can not receive data which is more than the buffer capacity;
3. If one can not determine the amount of data sent and received, it is recommended to use C series.
