Fast and convenient, easy to deploy

Support 4G, 3G, PPPoE, Wi-Fi network, digital IO input and output, serial terminal communication, and provide different solutions for different applications.

High-speed access, network-wide deployment

Support 4G (TDD LTE/FDD LTE), 3G (HSPA+/CDMA2000-EVDO/TDSCDMA), GPRS and other networks, fully covering all 4G/3G networks at home and abroad. To meet the needs of wireless access, it is easy to build a wireless local area network with a rate of up to 300Mbps.

Industrial grade design

Support 6V~35V wide voltage power supply, -20℃~70℃ industrial grade wide temperature design, adapt to more application sites with power supply requirements and temperature requirements. With IO control function, making remote control easy to achieve. With its own RS-232/RS-485 serial port wireless data terminal communication function, it is more in line with the needs of industrial customers. At the same time, it also has the following characteristics:
1)Metal shell, the protection level is IP30.
2)The EMC level indicators are up to level 3.
3)The Ethernet port supports 1.5KV isolation transformer protection.
4)The serial port supports 15KV ESD protection.

High reliability design

1) Link detection design: Support link real-time detection, realize automatic redialing of dropped calls, and maintain long link connections.
2) Equipment fault self-healing design: Embedded hardware watchdog and software watchdog technology, equipment operation fault self-healing, to ensure the equipment maintains high availability.
3) System Security Guard: Through the system security guard, real-time detection of system status and application status, prevention and recovery of unsafe and unstable nodes of the system.

Powerful security features

1) Data transmission security: Support L2TP, PPTP, IPSec VPN, Open VPN, and CA certificates to ensure secure data transmission.
2) Network protection security: Powerful firewall function, which can customize a full range of protection strategies according to customer needs, such as supporting SPI full state detection, Secure Shell (SSH), intrusion protection (forbidding Ping), DDoS defense, attack defense, IP -The wall function such as MAC binding protects the network from external attacks.

Simple to use, easy to operate and maintain

The WEB interface is user-friendly, with clear logic and clear at a glance, which greatly improves the efficiency of user configuration.
1) Supports reading logs locally or remotely, regardless of whether the management platform, WEB, or CLI are used, the logs read are clear and easy to understand, and the logs can help engineers quickly locate problems and improve work efficiency.
2) Querying the status information of the device router, such as CPU load, memory usage, network status, and device port status, is very important for troubleshooting.
3) Support engineers' advanced diagnosis function, which is convenient for quickly finding and repairing fault points during project construction

Support serial DTU transmission function

Support DTU serial transmission protocols such as WDTCP, WDUDP, TCP, UDP, etc., and support customized professional intelligent conversion protocols according to the needs of different industries.

Open platform, customized development

The computing power of up to 880x2 DMIPs is capable of various complex calculations; the rich system resources are suitable for developing various complex applications. Adopting the open platform design concept, customers can develop corresponding APPs by themselves or by the IoT development team and load them into the routing system according to specific application scenarios and application requirements.
