Unlimited single input (baud rate
≤
57600)
Continuous transmission without sub-package
C433-37
Unlimited single input (baud rate ≤57600)
Continuous transmission without sub-package
★ 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.
5.Operating mode
E90-DTU has four operating modes, if low power consumption is not required, normal communication is
recommended to configure the data transceiver for the normal mode (mode 0);
The factory default is normal mode (mode 0).

Description
Mode 0
Normal Mode
ON
ON
Open UART and RF，transparent transmission is on
Mode 1
Wake-up Mode
ON
OFF
Air wake-up mode, the packet comes with a
wake-up code,
Mode 2
Power-saving Mode
OFF
ON
The air wake-up receive mode, saving receive
power, the mode can not be transmitted
Mode 3
Sleep Mode
OFF
OFF
Parameter setting using the configuration
software
★ Note: no need to care about the wake-up mode (mode 1) and power saving mode (mode 2) if it doesn’t request low
power consumption.
