5.3. Frequency range and channels
Default frequency
Model
E32-DTU
(900L30)-V8
★ 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.
5.4. Transmit power level
Model
E32-DTU (900L30)-V8
★ 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.
5.5. Air data rate
Model
E32-DTU
(900L30)-V8
★ Note: The higher the air data rate, the fast
rate meets the requirements, the lower air data r ate, the better quality.
5.6. Current parameters
Model
E32-DTU
(900L30)-V8
★ Note: It is re
commended to retain more than 50% of the current margin when selecting the power supply, which
will help the data tra nsceiver to work steadily for a long time.
