5.3. Transmit power level

Mode
E90-DTU (170L30)
★ 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 (170L30)
★ 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.

5.5. Current parameters

Model
E90-DTU (170L30)
★ 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.

5.6. Transceiver Length and Sub-packing Mode

Model
E90-DTU (170L30)
★ Note:
1. If the data received by the station in a single time is larger than the capacity of a single packet, the exce ss data
will be automatically allocated to the second transmission until the completion of transmission.
2. The data transceiver cannot receive data which is more than the buffer capacity;
