Industrial Serial-to-Ethernet Gateway for Modern IIoT Connectivity
The ICS-3105AT Series is designed to bridge legacy RS-232, RS-422 and RS-485 devices with modern Industrial Ethernet and IIoT infrastructures. In addition to traditional Serial-to-Ethernet communication, the ICS-3105AT enables seamless integration between field devices and IP-based networks, helping users extend communication distances while preserving existing serial equipment investments. It provides an efficient migration path for factories, transportation systems, utilities and building automation applications to connect legacy assets into digitalized industrial environments without replacing existing devices or software systems.
MQTT Edge Gateway for Data Aggregation and Distribution
The ICS-3105AT Series expands traditional serial gateway functionality by supporting both MQTT Client and built-in MQTT Broker capabilities. It can collect data from PLCs, RTUs, sensors and industrial controllers through RS-232, RS-422 or RS-485 interfaces, convert the information into MQTT messages and publish them to SCADA systems, MES platforms, cloud services or third-party MQTT servers. The embedded MQTT Broker also enables local data exchange among connected devices without requiring an external broker.
Flexible Serial Operation Modes
The ICS-3105AT Series supports multiple serial operation modes, including TCP Server, TCP Client, UDP Client, Virtual COM, RFC2217, Telnet Server, Pair Connection and Modbus Converter Server/Client modes.These operation modes provide flexible connectivity for industrial communication applications and enable legacy serial devices to be integrated into Ethernet networks for remote access, monitoring, configuration and management.
Secure Remote Management and Cybersecurity
The ICS-3105AT Series provides remote management through web-based interfaces, SNMP and Windows-based VCOM Utility, allowing administrators to monitor, configure and maintain devices efficiently. To enhance network security, it supports HTTPS encrypted access, certificate management, SNMPv3, IEEE 802.1X authentication, RADIUS/TACACS+ user authentication, and Secure Boot technology, helping protect systems against unauthorized access and firmware tampering. Event Log, Syslog, SNMP Trap and Relay Alarm functions further simplify device maintenance and improve network reliability.
Stable Performance under Harsh Industrial Environments
The ICS-3105AT Series features a redundant dual power input design supporting 9V to 48V DC operation for enhanced system reliability. When the primary power source fails, the built-in hardware failover mechanism automatically switches to the backup supply, ensuring uninterrupted communications and continuous operation. This high-availability design is especially suitable for remote sites, process control systems and mission-critical industrial applications where maintaining network uptime is essential.
