Frequency range and channels

Model
E90-DTU(433C30)
★
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.

5.3. Transmit power level

Mode
E90-DTU (433C30)
★ 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.

5.4. Air data rate

Model
E90-DTU (433C30)
★ Note: The higher the air data rate, the faster the trans mission rate, the transmission distance is also closer; when the
rate meets the requirements, the lower air data rate, the better quality.

5.5. Current parameters

Model
E90-DTU (433C30)
★ 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.
