How to Use RUT955: Examples, Pinouts, and Specs

The RUT955 is a robust industrial router manufactured by Teltonika, designed for secure and reliable wireless communication in IoT applications. It supports multiple connectivity options, including LTE, Ethernet, and Wi-Fi, making it a versatile solution for remote monitoring, control, and data transmission in industrial, commercial, and residential environments.

This router is particularly well-suited for applications such as:

• Industrial automation and control systems
• Remote monitoring of sensors and devices
• Smart transportation and fleet management
• Renewable energy systems (e.g., solar or wind monitoring)
• Retail and Point-of-Sale (POS) systems

The RUT955 features multiple interfaces for connectivity and control. Below is a summary of its key ports and their functions:

1. Powering the Device:

   • Connect a DC power supply (9 V to 30 V) to the power input terminal block.
   • Ensure the power source is stable and within the specified voltage range.

2. Connecting to the Internet:

   • Insert a SIM card into one of the SIM slots for LTE connectivity.
   • Alternatively, connect the WAN port to an existing Ethernet network.

3. Configuring the Router:

   • Connect a computer to one of the LAN ports or via Wi-Fi.
   • Access the web interface by entering the default IP address (192.168.1.1) in a browser.
   • Log in using the default credentials (username: admin, password: admin01).
   • Follow the setup wizard to configure network settings, security, and other parameters.

4. Connecting Devices:

   • Use the LAN ports, Wi-Fi, or serial interfaces (RS232/RS485) to connect devices.
   • Configure digital I/O ports for monitoring or controlling external equipment.

• Antenna Placement: Ensure that LTE, Wi-Fi, and GNSS antennas are securely connected and positioned for optimal signal strength.
• Firmware Updates: Regularly update the firmware to ensure the latest features and security patches are applied.
• Power Supply: Use a stable and clean power source to avoid disruptions or damage to the device.
• Environmental Conditions: Install the router in a location that adheres to the operating temperature and humidity specifications.

The RUT955 can be used to send data from an Arduino UNO to a remote server via LTE. Below is an example of Arduino code to send sensor data over a serial connection to the RUT955:

#include <SoftwareSerial.h>

// Define RX and TX pins for SoftwareSerial
SoftwareSerial mySerial(10, 11); // RX = pin 10, TX = pin 11

void setup() {
  // Initialize serial communication with Arduino and RUT955
  Serial.begin(9600); // Arduino Serial Monitor
  mySerial.begin(9600); // Communication with RUT955

  // Print a message to indicate setup is complete
  Serial.println("Arduino is ready to send data to RUT955.");
}

void loop() {
  // Example: Send a temperature reading to RUT955
  float temperature = 25.5; // Replace with actual sensor reading
  mySerial.print("Temperature: ");
  mySerial.println(temperature);

  // Wait for 1 second before sending the next reading
  delay(1000);
}

Note: Ensure the RS232 or RS485 interface on the RUT955 is properly configured to receive data from the Arduino.

1. No Internet Connection:

   • Cause: Incorrect SIM card installation or APN settings.
   • Solution: Verify the SIM card is properly inserted and configure the correct APN in the web interface.

2. Unable to Access Web Interface:

   • Cause: Incorrect IP address or network configuration.
   • Solution: Ensure the computer is on the same subnet as the router (default IP: 192.168.1.1). Reset the router if necessary.

3. Weak Signal Strength:

   • Cause: Poor antenna placement or interference.
   • Solution: Reposition the antennas and ensure they are securely connected. Avoid placing the router near metal objects or other sources of interference.

4. Device Not Powering On:

   • Cause: Insufficient or unstable power supply.
   • Solution: Check the power source and ensure it meets the voltage and current requirements.

• Q: Can the RUT955 operate with dual SIM cards?

  • A: Yes, the RUT955 supports dual SIM functionality for failover and load balancing.

• Q: Is the RUT955 compatible with 5 GHz Wi-Fi?

  • A: No, the RUT955 only supports 2.4 GHz Wi-Fi.

• Q: How can I reset the router to factory settings?

  • A: Press and hold the reset button for 5 seconds until the LEDs start blinking.

• Q: Can I use the RUT955 in outdoor environments?

  • A: The RUT955 is designed for industrial use but should be installed in a weatherproof enclosure for outdoor applications.
