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.
