4.4 Electronic parameters

Mode
E92-DTU(2G4HD12)
★Note: 12V transient transmission MAX current: 66mA, 24V transient transmission MAX current: 33mA, it is
recommended to keep ≥50% MAX current margin when selecting the power supply, which is conducive to the long-term
stable operation of the radio.

4.5 Default parameters

5 Detailed function

5.1 Point-to-point communication mechanism

The valid range of communication link value is 1 to 9999, which can be set by AT command or upper computer. The
factory default setting of the communication link value is "1";
If the connection is disconnected due to power failure, excessive distance, or strong interference, it is recommended
to adjust the distance appropriately or avoid obstacles, and the radio enters the search state again until it searches for
the device with the same link and establishes a connection.
If there are two or more E92-DTU (2G4HD12) bridges with the same communication link, and they are powered on
at the same time, a random connection will be established in pairs. If it involves multiple bridge applications, it is
recommended to configure the link value of each pair of bridges in advance to distinguish them.

5.2 Full duplex/high-speed continuous transmission

During two-way communication, especially when transferring files, the channel resources occupied by the two ends
are different, which will cause the transmission rate of one end to be slower than the other end, which is normal;
During continuous data transmission, such as sending large files, to make full use of the transmission rate, please
ensure that the data stream is continuous. Frequent small data frame breaks may reduce wireless transmission
efficiency.
