Serial to 4G, Bidirectional Transparent DataTransmission
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.
Modbus Gateway
Connect to PLC, SCADA system or user’s private server to achieve local or remote motoring.
FOTA Remote Upgrade
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.
Additional Features
-
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.
