Explore the capabilities of the Teltonika RUT955 industrial router

Network devices with specialized purposes are difficult to compare with classical business counterparts. Therefore, the RUT955 router from Teltonika company is simply a different class of equipment in comparison with proposals of Mikrotik, Ubiquiti Networks, Cambium Networks, Aruba or Cisco. LTE Cat 4 industrial mobile router, as the device is called by the Lithuanian manufacturer, is a compact but rugged design with the necessary interfaces and LTE connectivity. It is based on an advanced motherboard and the RutOS system creating additional software functions. Wide possibilities of the equipment designed for numerous applications in the category of industrial automation, transport or smart house prove to be perfect. RMS, the refined remote management system expands possibilities of the device. Teltonika RUT955 is the choice of professionals who aware of their needs and able to take advantage of the wealth of possibilities offered by this seemingly simple router.

The router has relatively small dimensions allowing to use it even in tight spaces. Robust housing, with the option of mounting it, hides two boards with a number of features. The first one is based on Atheros AR9344-DC3A chipset with a CPU 74Kc MIPS 533MHz, 128 MB DDR2 RAM, FLASH 16 MB SPI Flash. It is equipped with a USB 2.0 port, PCI Express connector, WiFi card working in 2.4GHz 802.11n MIMO 2x2 standard, as well as GPIO and UART connectors. On the second board, a Category 4 LTE modem provides dual SIM support and speeds up to 150Mbps/50Mbps. Interfaces of 4 x Ethernet, digital and analog I / O, RS232, RS485, GNSS - GPS, as well as microSD and USB provide a variety of business and industrial application scenarios.

The RUT955 router allows you to create a redundant LTE connection to ensure maximum reliability of Internet connectivity and communication with the device. This is possible thanks to support for two SIM cards. The connection is available interchangeably, in certain situations the link from the selected card is swapped for the other. For example, you can use cards from two different operators to limit situations of no transmission due to poor coverage or running out of data. Switching to an alternative SIM card can take place in situations when:

• Mobile network signal deteriorates,
• Your data or SMS limit has been reached,
• You lose your connection or there is a connection error,
• Roaming connection is discovered.

Which scenarios are supported is at the discretion of the person configuring the device. Additionally, the router has the ability to operate in Dual WAN mode, where one of the Ethernet ports provides network connectivity, while the LTE modem can be treated as a dual backup connection. It is worth noting that, according to the tests, better parameters of the connection with LTE network for the connected computer are achieved with wired LAN configuration, not with WiFi connection. However, this may be a result of the influence of external factors that have not been properly verified.

The router's physical interfaces allow it to interact with multiple devices, verify their operation, and connect other network devices to the network. These include the previously mentioned:

• 4 FastEthernet ports:
  • 1 x WAN port configurable as LAN - 10/100 Mbps, compliant with IEEE 802.3, IEEE 802.3u, auto MDI/MDIX,
  • 3 x LAN port 10/100 Mbps, compliant with IEEE 802.3, IEEE 802.3u, auto MDI/MDIX.
• Impact IEEE 802.11b/g/n WiFi interface, with the ability to operate as Access Point (AP), Station (STA) and rich security configuration options,
• Serial port:
  • RS232 DB9 connector, full RS232 (RTS, CTS),
  • RS485 Full Duplex and Half Duplex, 300-115200 baud rate,
• Inputs:
  • digital 0 - 3 V,
  • Galvanically isolated digital 0 - 30 V,
  • Analogue 0 - 30 V
  • analogue 0 - 24 V,
  • Digital non-isolated on 4th pin of power supply connector.
• USB 2.0 supporting Samba share or custom scripts, with the ability to plug in a HDD, Flash, printer or modem.
• Micro SD card slot,
• Antenna connectors:
  • 2 x SMA for LTE,
  • 1 x SMA for GNSS,
  • 2 x RP-SMA for WiFi antennas,

Developed RutOS software with advanced functionality of Modbus, SNMP, TR-069, NTRIP, MQTT or various VPN services, as well as extensibility and remote management allows to create even very advanced scenarios using all interfaces.

The operating system on the RUT955 Teltonika router provides almost unlimited configuration options, which are further extended by the option to upload additional packages or program own scripts thanks to the SDK. The RMS platform - Remote Management System allows for remote management, while the web interface enables local administration. RMS, or convenient remote control and administration

Teltonika RUT955 is compatible with Teltonika Networks remote control system. This offers a wealth of possibilities available from the outside. The software has three core modules available in both a simple WebUI interface via HTTP/HTTPS and SSH/CLI:

• RMS MANAGEMENT provides complete control, security and availability,
• RMS CONNECT allows remote access to other smart devices, even if they do not have a public IP address,
• RMS API allows you to implement RMS functionality on the IoT platform of your choice.

The full configuration capabilities of the RUT955 are available through the WebUI after logging in and making initial settings. Complete support for all features of the device is provided by the manufacturer in the online RUT955 Wiki and documentation

Teltonika's RUT955 router helps provide stable data transmission for selected IoT or IIoT devices, such as sensors of various types or components of a complex system. It is also equipment that allows location monitoring, notification of location change thanks to LTE and GNSS: GPS, GLONASS, BeiDou, Galileo or QZSS. It can prove itself, for example, as equipment providing communication of ships, boats or mobile industrial automation systems. Teltonika Networks RUT955 can be a main element of alarm system - control panel with ability to send notifications about status of sensors, connect with compatible devices, for example monitoring system. This router can also be successfully used as a SMS gateway or remote RS232/435 port.

Devices offered by Teltonika Networks are exceptionally refined, constantly developed due to the dynamic progress of their application area. Therefore, even if some parameters may seem limited or potentially easy to improve, they will certainly be changed or developed in the future. Sophisticated RMS system, ready-to-use functionalities for business solutions like VRRP or Dual WAN with load balancing or FailOver option, advanced built-in firewall or WatchDog encourage to choose this device. It is worth to get acquainted with the full specification available at the manufacturer's website. Some inconveniences, such as support only for WiFi 802.11 2.4 GHz b/g/n standard, lack of Polish version of the user interface, or industrial power connector - not very popular among similar sized network devices - are the matter of choosing the equipment according to individual needs and generally accepted standards in the world of network devices. In industrial applications, for which RUT955 router has been created - IIoT or IoT, the specifications of the device look very promising.
