Air Data Rate; Current; Tx And Rx Fifo And Sub-Packing Method; Function Description - Ebyte E90-DTU Manual

Chengdu Ebyte Electronic Technology Co., Ltd.
E90-DTU(400SL30P)
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
E90-DTU(400SL30
P)
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.

5.6 Current

Model
E90-DTU(400SL30
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.

5.7 TX and RX FIFO and sub-packing method

Model No.
E90-DTU(400SL30P
)
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 can not receive data which is more than the buffer capacity;

6. Function Description

6.1 Fixed Transmission（Hexadecimal）
During fixed-point transmission, the module recognizes the first three bytes of the serial data received as:
Address high + address low + channel, and use it as a wireless transmission target.
