[Introduction]：E90-DTU(433L30)E est une passerelle sans fil (radio de transmission de données d'interface Ethernet) qui prend en charge un débit de 10 M/100 M et est développée par Chengdu Ebyte sur la base de la technologie de communication LoRa et du protocole Ethernet.La coque adopte un revêtement à trois niveaux : antifongique, anti-humidité et anti-sel. Prend en charge le socket bidirectionnel, fournit six modes de fonctionnement : serveur TCP, client TCP, serveur UDP, client UDP, client HTTP, client MQTT et prend en charge les connexions client à six voies en mode serveur TCP.

【Note】
1.
When using multiple groups of digital transmission radio stations for
simultaneous one-to-one communication in the same area, it is
recommended that each group of digital transmission radio stations set a
channel spacing of more than 2MHz;
2. The lower the transmission
power, the closer the transmission distance, but the operating current
will not decrease proportionally. It is recommended to use the maximum
transmission power;
3. The power adjustment function cannot
accurately feedback the actual transmit power of "medium", "low" and
"extremely low". The values in the table are for reference only and
other powers can be customized;
