    Industrial 4G LTE Router
    With Serial Port

    Serial Modem

    G781 integrates with routing and serial modem, which can easily achieve the
    bi-directional data transparent transmission between RS485/RS232 devices
    and 4G network, supports connecting to various cloud platforms.
    It also supports user-defined register & heartbeat packets to ensure the
    device online

    Transparent Transmission

    Provide data two-way transparent transmission between field serial devices and the
    central control server Support 4 Socket connections, support TCP Client and UDP
    Support custom heartbeat package and registration package
    Private protocols can be customized

    HTTPD Client

    submit serial data to the designated server by HTTP (GET/POST) method

    Modbus RTU to TCP

    Modbus RTU/Modbus TCP protocol conversion for industrial SCADA
    systems and field devices.

    Registration Package plus Heartbeat Package

    The registration packet is sent to the server to identify the device.
    The heartbeat packet is used to judge the active state of the device when
    sent to the server, and actively collect data when sent to the serial terminal.
    The contents of registration package and heartbeat package,
    heartbeat interval can be modified by AT command.

    Industrial Design, Fit into Any Harsh Environment

    ESD, Surge, EFT protection, wide input voltage.Built-in hardware watchdog,
    7*24 hours stable operation in harsh environment or industrial site with strong
    electromagnetic interference.
    All components are selected according to industrial standards,Thicker and durable
    metal shell, ground screw protection.

    Data Security, Multiple VPN

    Supports mainstream VPN protocols, including PPTP, L2TP, IPSec, OpenVPN,
    and GRE. Multiple safe encryption methods make data safe
    transmission up to financial grade.

    Flexible networking

    Video Surveillance

    Through 4G networking, it provides high-speed network access for cameras,
    and other devices that require large data transmission,
    so that staff can remotely monitor the details of the field.
