Reliable connectivity. Intelligent backup. Industrial durability.

The HoweVis HVT-IR557-52X Series Industrial 5G RedCap/4G/3G 5-Port Cellular Gateway Router is designed to deliver secure, stable, and always-on connectivity for Industrial IoT, remote monitoring, automation systems, and unattended equipment. Combining high-speed cellular communication, wired Ethernet, optional Wi-Fi, serial connectivity, VPN security, and industrial-grade hardware protection in one compact device, it provides a dependable networking solution where fixed broadband is unavailable, unstable, or difficult to install.

With one configurable WAN/LAN port and four LAN ports, the HVT-IR557-52X Series can connect multiple Ethernet devices through a single gateway. It is ideal for PLCs, HMIs, industrial PCs, IP cameras, sensors, controllers, smart lockers, digital signage, self-service terminals, and other network-enabled equipment. The built-in RS232 port, optional RS485 port, and optional I/O interfaces also enable convenient integration with serial devices, field instruments, and industrial control systems.

The router supports flexible cellular options, including 5G RedCap, 5G, 4G, and 3G connectivity. 5G RedCap provides an efficient option for IoT applications that need the extended coverage and low-latency advantages of 5G while optimizing device complexity and deployment cost. Selected 5G models support both SA and NSA networking, while 4G models can support CAT1, CAT4, or CAT6 configurations. Optional 2.4 GHz Wi-Fi, single-SIM, and dual-SIM versions allow customers to select the right configuration according to local carrier coverage, data demand, and project requirements.

Built for continuous operation, the HVT-IR557-52X Series supports wired broadband, cellular WAN, and optional Wi-Fi access with intelligent network backup. When the primary network becomes unavailable, the router can switch to an available backup connection to help maintain data transmission. Optional dual-SIM failover, link detection, automatic redial, communication module restart, and watchdog-based recovery functions reduce downtime and limit the need for onsite service. This makes the router especially suitable for remote and unmanned locations where network stability is essential.

Security is integrated into the router’s network architecture. The device supports VPN technologies including IPSec, OpenVPN, PPTP, L2TP, and GRE for secure remote communication. Additional protections include SPI firewall, DoS defense, ACL access control, NAT, port forwarding, DMZ, IP/MAC binding, and multi-level user management. These functions help protect communications between field devices, cloud platforms, control centers, and remote maintenance teams.

For Industrial IoT integration, the router supports MQTT, Modbus TCP, Modbus RTU, EtherNet/IP, NTRIP, and other communication functions for data collection, protocol conversion, remote control, and cloud connectivity. It also supports remote configuration, firmware upgrades, system logs, SNMP, and TR-069 management, helping operators manage distributed devices more efficiently.

Designed for demanding industrial environments, the HVT-IR557-52X Series features a rugged metal enclosure, IP31 protection, 7–32 VDC wide-voltage input, reverse-polarity and overvoltage protection, Ethernet isolation, and ESD protection. With an operating temperature range of -35°C to 75°C, it is a reliable connectivity solution for smart manufacturing, transportation, energy, utilities, environmental monitoring, security, and remote asset-management applications.

Online maintenance of patented technology

• Supports the online maintenance function to prevent offline processing. Uses special algorithms to continuously communicate with the base station and activate the online status of devices to ensure online stability.
• Re-establish the dial-up mechanism. Even if the call is disconnected, the system will go online again within tens of milliseconds. The time is so short that people cannot notice it at all.
• Restart the communication module and establish a new connection.
• Power off the equipment and restart the whole machine, eliminating the need for manual on-site power removal, reducing maintenance costs for enterprises.

 Network backup

• The device supports LAN WIFI function and wide area network 3G/4G/5G wireless network function;
• Supports switching between wired and wireless networks to achieve network backup function.
• Supports network backup with dual SIM cards (optional).

 Full network

• 5G cellular access, supporting SA and NSA networking.
• 4G cellular access, CAT1, CAT4/CAT6 networking, backward compatible with 3G/2G networks;

Supports large-scale deployment

In the application of industrial internet of things, facing thousands of terminal devices connected to the network, tens of thousands of routers need to be deployed. Effectively help you solve device management and deployment problems;

Can be customizedPython development platform

Supports secondary development platform based on Python language, allowing users to customize APP applications according to their own business. The gateway supports Linux OpenWRT system development.

 Supports multiple industrial protocols

To be compatible with many industrial controller devices on the market, the gateway supports the following industrial protocols: Modbus TCP, Modbus RTU, EtherNet/IP, Modbus TCP Slave, etc.;

Supports multiple industrial cloud ecosystems

HoweVis Gateway supports the following industrial cloud platforms: IoT cloud platforms such as Alibaba Cloud, Tencent Cloud, Power Cloud Platform, and Amazon AWS are committed to developing the industrial IoT cloud ecosystem in order to provide customers with more solutions.

Complete security features

• Supports VPN security tunnel functions, including PPTP, L2TP, IPSEC, and OpenVPN.It also supports multiple protocols: TCP/IP, UDP, ICMP, etc.;
• DMZ isolation, virtual IP mapping, MAC-IP address binding, WAN port access restriction, and other firewall functions, with multiple security protection measures to ensure that the network is not attacked by external sources.
• Supports device user rights management, network security, data security, and other security protection functions.

 High-reliability design

Three-layer system protection: On the basis of the original two-level system protection (software protection + CPU built-in watchdog WDT protection), the first-level system virtual watch (VWM) detection protection function is added. When the network is abnormal or the system receives strong interference, the system will be completely reset. It is equivalent to the maintenance personnel coming to the door to unplug the power, which completely solves the trouble of on-site unplugging when the system is abnormal in the industry, ensuring the stability and reliability of the system.

High-speed processing CPU: High-speed industrial-grade CPUs are used to process various protocols data transformation at a higher speed. Solve the difficult problems in the industry such as “fake online,” “fake crash,” and “downtime.”

Excellent stability performance: Passed the 3000V electric shock test, especially suitable for use in harsh industrial environments; The system has excellent EMC/EMI, and the system is stable and reliable. Passed CE certification, FCC certification, ROHS certification, E-mark certification, 3C certification, molar high and low temperature testing certification, and EMC testing.
