Industrial LTE Cat4 Router TELTONIKA RUT986 with Dual SIM/eSIM, RS232/485, GNSS

TELTONIKA RUT986 is an industrial LTE Cat4 router that provides secure and reliable cellular connectivity for machine-to-machine and Internet of Things deployments. The device combines Dual SIM and eSIM support for mobile network redundancy, integrated GNSS for position and time services, and serial interfaces RS232 and RS485 to connect industrial equipment. Designed for continuous operation in commercial and industrial environments, the RUT986 supports standard routing features and remote management over cellular networks.

Advantages

The router offers LTE Cat4 data rates suitable for telemetry, remote monitoring and low-to-medium bandwidth applications. Dual SIM combined with eSIM enables automatic failover between operators to maintain network availability. Built-in GNSS simplifies location tracking and time synchronization for asset management and fleet applications. RS232 and RS485 serial ports allow direct integration with legacy industrial sensors, PLCs and metering equipment. A robust hardware design and industrial-grade interfaces ensure stable performance in distributed installations.

Suitable for

• M2M and IoT connectivity for remote sensors and controllers
• Fleet tracking and telematics with GNSS-based location
• Remote monitoring of industrial installations and utilities
• Integration with serial-based devices such as PLCs, meters and modems

Key specifications

• Cellular: LTE Cat4 with fallback to 3G/2G where supported by networks
• SIM support: Dual physical SIM slots plus embedded eSIM functionality for operator redundancy
• Interfaces: RJ45 Ethernet ports for WAN/LAN; RS232 and RS485 serial interfaces for industrial device integration
• Location: Integrated GNSS receiver for GPS/GLONASS-based positioning and time services
• Management: Remote configuration and firmware updates via web UI and remote management protocols
• Power and mounting: Industrial power input range and DIN-rail or panel mounting options for installation flexibility

How to use

Install the RUT986 in a sheltered location with sufficient cellular coverage and connect the power supply according to the manufacturer’s installation instructions. Insert one or two physical SIM cards and configure the eSIM profile if required. Connect Ethernet and serial devices as needed: use Ethernet for IP-based equipment and RS232/RS485 for serial instrumentation and controllers. Access the router’s web interface to set APN and network preferences, configure routing, firewall rules and enable GNSS reporting for location-dependent services. Use the remote management system to monitor device health and apply configuration changes or firmware updates remotely.

Recommendations

For reliable operation, place the router where cellular signal strength is adequate and use external antennas if coverage is marginal. Configure SIM failover and keep firmware up to date to maintain security and compatibility. When connecting serial devices, verify wiring and protocol settings (baud rate, parity, stop bits) to ensure correct data exchange. For fleet or asset tracking, enable GNSS reporting intervals appropriate to the use case to balance location accuracy and data usage.
