Teltonika RUTM09 Industrial 4G LTE Cat 6 Dual SIM Router

Configure dual SIM failover via the RutOS web interface under the 'Mobile' section. Set the primary and backup SIM slots, then define failover triggers such as signal loss, data limit exceeded, or SMS command. The router automatically switches to the backup SIM when the primary connection fails, ensuring continuous uptime for critical IoT deployments.

Yes, the RUTM09 has built-in Modbus TCP gateway functionality. Enable the Modbus service in RutOS, define your serial (RS-485/232) or TCP slave devices, and map registers. The router will poll data from field devices like PLCs and sensors, then forward it via MQTT or a direct TCP connection to your SCADA or cloud platform, acting as a protocol converter and secure data concentrator.

First, ensure the RUTM09 is registered on your Teltonika RMS account. In the RMS portal, navigate to the device list, select your router, and go to the 'Firmware' tab. You can upload a new firmware file or select an official update. Schedule the update or apply it immediately; the RMS will push the firmware securely over the air, and the router will reboot automatically upon completion.

The digital input (DI) accepts 0-6V as LOW and 8-50V as HIGH. Connect your sensor's output to the DI pin and GND. The digital output (DO) is an open-collector output (max 50V, 300mA). Configure the I/O behavior in RutOS—for example, trigger an SMS alert or change VPN tunnel state based on the DI status, or control an external relay/siren using the DO pin via scripts or RMS rules.
