4G router INSYS icom SCR-L300 — montáž na DIN lištu/stenu, SMA anténa, BGP/OSPF/RIP, 10/100 Mbit/s LAN

INSYS icom SCR-L300 is a 4G industrial router designed for DIN-rail or wall mounting, providing mobile WAN connectivity with MiniSIM and SMA antenna connection. The device supports common 4G bands (700, 800, 900, 1800, 2100 MHz) and offers two 10/100 Mbps LAN ports for local network access. The SCR-L300 runs the icom OS with an integrated icom SmartBox Linux environment, enabling script execution and container-based applications at the edge. Routing capabilities include BGP, OSPF, RIP, RIP-2 and RIPng, and the product includes LED indicators for power, signal strength and WAN status.

Advantages

The SCR-L300 combines compact mechanical design with industrial-grade networking features: flexible DIN-rail or wall mounting and a flat housing allow installation in switch cabinets or connection boxes. It supports retrofitting of legacy serial devices through Modbus TCP/RTU and an RS232 interface, enabling migration of older plants into modern IoT environments. The integrated icom SmartBox enables local data processing, scripts and containers for edge computing and simple cloud integration. Energy-saving sleep mode allows operation with limited power supplies such as solar or battery systems.

Key specifications

How to use

Install the SCR-L300 on a DIN rail or fix it to a wall in a suitable enclosure, connect the MiniSIM card and attach an SMA antenna for improved cellular reception. Connect local devices via the two 10/100 Mbps Ethernet ports or the RS232 serial port and configure network settings through the icom OS web interface or command line. Set up routing and VPN profiles as required, and deploy containerized scripts in the icom SmartBox to process or forward data locally. Use the LED indicators to verify power, signal and WAN status during commissioning.

Recommendations

Place the antenna in a location with good sky visibility to maximise cellular signal. Use the sleep mode for deployments with limited power and verify I/O wiring and serial termination before applying full operational loads. Regularly update the icom OS and installed containers to maintain security and compatibility.
