Description

The Teltonika TRB142 is a compact, rugged LTE gateway engineered for industrial IoT and M2M applications requiring reliable serial connectivity. It bridges the gap between legacy RS232-equipped machinery and modern cellular networks using LTE Cat 1 with 3G/2G fallback, ensuring continuous data transmission even in remote or challenging locations. The device runs on RutOS, a powerful OpenWrt-based Linux distribution, providing a fully customizable platform for networking, security, and automation tasks.

Built with an aluminium alloy housing, the TRB142 is designed to withstand extreme temperatures from -40°C to +75°C and accepts a wide 9–30 VDC input, making it suitable for deployment in transportation, utilities, and industrial automation. Its integrated RS232 port supports direct connection to PLCs, sensors, meters, and other serial devices, facilitating seamless upgrades to cellular telemetry without replacing existing infrastructure.

Key Features

  • Industrial-grade LTE Cat 1 cellular gateway with dedicated RS232 (DB9) serial interface for legacy equipment integration.
  • Runs RutOS, an OpenWrt-based Linux OS, offering extensive customization, scripting, and advanced networking capabilities.
  • Robust aluminium housing and wide operating temperature range (-40°C to +75°C) for deployment in harsh industrial environments.
  • Comprehensive security suite including configurable firewall, VPN tunnels (OpenVPN, IPsec, WireGuard), and encrypted communication.
  • Multiple control and management interfaces: Web UI, SMS, CLI, Teltonika RMS cloud platform, and REST API for remote configuration.
  • Supports major industrial IoT protocols like Modbus (RTU/TCP), MQTT, and OPC UA for seamless integration into automation systems.
  • Low power consumption (<5W) with a wide 9–30 VDC input range, compatible with vehicle and industrial power systems.
  • Integrated 1.2 GHz ARM Cortex-A7 processor with 128 MB RAM and 512 MB Flash for handling complex routing and data processing tasks.

Frequently Asked Questions

What operating system does the TRB142 run, and how is it configured?

The TRtonika TRB142 runs RutOS, a customized OpenWrt-based Linux distribution. Configuration is primarily done via a secure web interface accessible through its LAN IP. Advanced users can utilize SSH for command-line access, and the device supports remote management through the Teltonika RMS cloud platform or direct API calls for integration into larger systems.

How do I connect a serial device and send data over LTE with the TRB142?

Connect your serial device (e.g., PLC, sensor) to the gateway's DB9 RS232 port using a standard serial cable. Configure the serial parameters (baud rate, parity) in the TRB142's web interface under the Serial section. Then, set up a data forwarding rule, such as a TCP/UDP tunnel or MQTT client, to route the serial data over the established LTE connection to your remote server or cloud platform.

What VPN protocols are supported for securing data transmission?

The TRB142 gateway supports multiple industrial-grade VPN protocols to encrypt data in transit. These include OpenVPN for flexible client-server tunnels, IPsec for site-to-site network security, and the modern WireGuard protocol for high-performance encrypted connections. Configuration for each is available within the RutOS web interface under the VPN services menu.

What is the power requirement, and can it be powered from a vehicle?

The TRB142 accepts a wide 9 to 30 VDC input, with typical consumption under 5 watts. This range makes it directly compatible with 12V or 24V vehicle electrical systems, industrial power supplies, and solar/battery setups. Ensure to use the provided 9W PSU for bench testing or a suitably rated, stable DC source for field deployment.
