With this 4G modem, traditional serial devices can be connected to 4G network and send data to remote server via TCP/UDP/MQTT protocol. For MQTT protocol,
it supports SSL encryption whicn can protect the data from leaking.
Connect to PLC, SCADA system or user’s private server to achieve local or remote motoring.
With the management platform, it can realize the remote firmware upgrade. The upgrade package of difference algorithm is small, and the upgrade traffic and time are saved.
Heartbeat Packet Server can detect abnormal disconnection from the client using this feature(DR3X as an TCP client).
Registration Packet The server can identify different clients by using registration packets.
3 Practical Designs, Easy Your Installation.
Ultra-small size like a lipstick, can be applied to various scenarios, especially the small box.
Appearance patent number: 202130367085.8.
Push-type, pluggable wire connector, easy wiring, no need for additional tools such as screwdrivers.

Pluggable wire connector.
Watchdog Protection
Hardware & software dual watchdog to ensure stable operation.
EMC Protection: Level 2
Wide Operating Temp
-25℃ ~ 75℃, industrial grade design, stable operation in harsh environments.
Flame retardant rating: V0, burning stops within 10 seconds on a vertical part allowing for drops of plastic that are not inflames.
