Ethernet Gateway LoRa 915MHz E90-DTU(900SL22) E MQTT 22dBm DC 8V~28V 5km RSSI SMA-K TCP UDP Transceiver Modem

Fully functional gateway configuration One-click view of device status.ModBus TCP to RTU,ModBus TCP to RTU Support standard ModBus TCP to RTU protocol automatic conversion. Active upload mode,Multi-host gateway mode,Multi-host gateway mode,Configurable Gateway Mode. Standard MQTT protocol Can be connected to multiple cloud platforms, loT platform that supports standard MQTT protocol.RSSI signal detection. Composed of data RSSI and environmental RSSI, Data RSS is the signal quality at the time of sending data, Environmental RSSI is the signal strength between the two communicating parties Multi-host mode Allows multiple network hosts to read and write slave data through the device without conflict. Automatic relay The device has the function of relay and forwarding to extend the communication distance. Take the initiative to report.The gateway can be used as the ModBus master stack to poll the slave devices, and the data returned by the device is directly sent to the server, without the need for the server to actively collect. Safe and reliable, can be used in hazardous chemical industry Explosion-proof certification;Built-in watchdog stable without crash.Built-in watchdog design, exception occurs Automatic restart, no need to be on duty, stable and reliable. Multi-protocol transparen transmission 
Adapt to a variety of loT communication protocols 
Meet the needs of local devices to upload data to the server.
