Reliable 4G LTE Connectivity

The RUT956 delivers 4G LTE Cat 4 performance with download speeds up to 150 Mbps and upload speeds up to 50 Mbps. It also supports 3G and 2G networks when needed, ensuring operation even in areas where high-speed cellular coverage is limited.

This makes the RUT956 particularly useful in locations where fixed broadband isn’t available, unreliable, or hard to install.

Dual SIM for Network Failover

With two SIM slots, the RUT956 supports switching between SIM cards. It can change SIMs based on signal strength, data limits, roaming conditions, network outages or connection failures.

This feature is especially helpful for installations where losing internet access could disrupt equipment monitoring or production processes.

Ethernet and Wi-Fi

The router includes four 10/100 Mbps Ethernet ports. One can be used as WAN or LAN, and three LAN ports. It also has built-in 2.4 GHz Wi-Fi, allowing wireless devices to connect directly without needing hardware.

Devices such as computers, industrial controllers, CCTV cameras, IoT sensors, network equipment, and remote monitoring systems can easily connect to the RUT956.

RS232 and RS485 Industrial Connectivity

One of the advantages of the RUT956 is its ability to connect directly with industrial equipment through RS232 and RS485 interfaces.

These serial connections are commonly found in:

• PLCs
• Industrial controllers
• Meters
• Sensors
• Automation equipment
• Monitoring systems
• Devices

The RUT956 supports industrial communication protocols like Modbus TCP, Modbus RTU and Modbus over MQTT. This allows older serial devices to communicate with IP-based networks.

Simple Example

PLC / Sensor → RS485 → RUT956 → 4G LTE → Cloud / Office

This setup enables equipment at a site to send data back to a central monitoring system.

GNSS / GPS Location Support

The RUT956 has a built-in GNSS module that supports:

• GPS
• GLONASS
• – BeiDou
• – Galileo
• – QZSS

This technology is useful for location services, time synchronization, geofencing, and tracking vehicles or assets.

Teltonika also provides documentation showing how the RUT956 can be used in transportation applications, where cellular and GPS data help monitor vehicle positions and operational status.

Industrial I/O

The RUT956 comes with input and output options for connecting outside equipment.

Depending on the hardware revision these include inputs, isolated inputs, analog input, open-collector outputs, and a relay output.

These I/O functions can monitor equipment conditions or trigger actions when events happen. For example, a system might use an input to check if a machine is running and send an alert if it stops unexpectedly.

USB and MicroSD Support

The router has a USB 2.0 Type-A port that supports devices like storage drives, printers, and USB-to-serial adapters. The internal MicroSD card slot allows for storage or firmware updates.

Teltonika lists uses for USB including backup storage, printer connectivity and serial communications.

Advanced Networking

The RUT956 runs on RutOS, a custom operating system based on OpenWrt. It includes tools for:

• – Routing
• – Firewall
• – DHCP
• – VPN
• – Failover
• – Load balancing
• – QoS
• – DDNS
• – Connection monitoring
• – Remote management
• – SNMP
• – MQTT
• – Modbus
• – SSH
• – SMS management

These features let the RUT956 be configured for internet access or complex industrial networking solutions.

Remote Management with RMS

The RUT956 works with Teltonika Remote Management System (RMS). This platform helps companies manage their deployed routers across locations, especially where physical access is difficult.

RMS allows users to monitor device status, update configurations, and troubleshoot issues remotely.

Where Can You Use Teltonika RUT956?

• Industrial Automation

Use the RUT956 to connect PLCs, sensors, controllers and other industrial equipment to a network using 4G LTE, Ethernet, RS232 or RS485.

• Transportation

Combining 4G LTE, Wi-Fi, GNSS, Ethernet and I/O makes the RUT956 well-suited for buses, trucks and transport systems. Applications include CCTV connectivity, passenger information systems and vehicle tracking.

• Energy & Utilities

Connect remote monitoring equipment, meters, controllers and infrastructure where wired internet isn’t practical.

• Telecom Towers

The RUT956 acts as a connectivity hub for telecom towers, providing data for monitoring and communication at distributed tower sites.

• Smart City Projects

Connect infrastructure, monitoring systems, and control devices through cellular connections.

• Remote Monitoring

Ideal for equipment located far from the main office where businesses need to monitor machines or access systems remotely.

• Enterprise Networking

The RUT956 can serve as out-of-band management, giving a cellular link for accessing network infrastructure.

• Retail & Commercial Locations

Use the RUT956 as a backup internet connection for retail stores, offices or commercial sites where consistent connectivity matters.

Technical Knowledge – How Does the RUT956 Work?

Think of the RUT956 as a communication hub between your devices and the internet.

For example:

Industrial Sensor → RS485 → RUT956 → 4G LTE → Cloud

CCTV / Computer → Ethernet → RUT956 → 4G LTE → Remote Office

The router collects data from equipment, manages the network, and sends the information over the best available connection. Whether cellular or wired.

If the main SIM connection fails, the Dual SIM failover automatically switches to the SIM according to user-defined rules.

Weight

The Teltonika RUT956 has a design measuring about:

• 110 × 50 × 100 mm (width × height × depth)
• Its weight is approximately 287 grams. While some measurement methods may show differences, the datasheet figure is the official specification.
• The aluminum casing and wide temperature range from -40°C to +75°C make it suitable for industrial settings.

Why Do Customers Need the Teltonika RUT956?

The RUT956 is not a regular consumer-grade 4G router. It combines 4G LTE, Dual SIM, Wi-Fi, Ethernet, RS232, RS485, GNSS and industrial I/O into one package.

This means a single device can handle internet access, industrial communication, remote monitoring and location-based tasks.

Businesses with machinery, vehicles, industrial equipment, telecom towers, utility systems or scattered operations can rely on the RUT956 to keep everything connected and manageable.

In short, if your business needs 4G connectivity plus industrial interfaces for machines and remote systems, the Teltonika RUT956 offers the features and reliability required to build that solution.
