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).
