Description

The Wittelb WIN-GW is a robust industrial IoT gateway engineered to bridge legacy serial devices and modern cloud infrastructure. It integrates a 4G LTE modem for primary WAN connectivity, ensuring operational continuity in field deployments. The gateway translates Modbus RTU data from connected RS485 sensors and controllers into TCP/IP packets, which can be routed locally via Ethernet or transmitted to the cloud using the lightweight MQTT protocol.

Built for 24/7 operation in challenging environments, the device supports a wide 12V DC input range (15-40VDC) and operates within a 0–60°C temperature range. Its integrated web server provides a configuration portal for setting APN details, MQTT broker parameters, and Modbus register mappings, eliminating the need for proprietary software. This makes it an ideal drop-in solution for upgrading existing SCADA, telemetry, and asset monitoring systems to cellular and cloud-based architectures.

Key Features

  • 4G LTE Cellular Modem: Delivers broadband internet access for data backhaul, supporting global LTE frequency bands for deployment flexibility.
  • Modbus RTU/TCP Gateway: Acts as a protocol converter, enabling RS485-based industrial devices to communicate over IP networks and cloud platforms.
  • Dual Network Interfaces: Combines cellular WAN with a local Ethernet port for creating hybrid network topologies or local device communication.
  • MQTT Client with TLS Support: Facilitates secure, publish-subscribe messaging to cloud IoT hubs for efficient, scalable data ingestion.
  • Local Data Logging: MicroSD card slot allows for storage of sensor readings and event logs during network outages, ensuring data integrity.
  • Wide-Range DC Power Input: Accepts 15-40VDC, making it compatible with industrial power supplies, solar-charged batteries, and vehicle systems.
  • Web-Based Management Console: Offers an accessible interface for configuration, real-time status monitoring, and firmware updates without specialized tools.

Applications

  • Industrial Telemetry & SCADA: Remote monitoring of water treatment plants, oil & gas pipelines, and manufacturing equipment via 4G networks.
  • Smart Agriculture: Connecting soil moisture sensors, weather stations, and irrigation controllers in fields without wired internet.
  • Fleet & Asset Tracking: Enabling GPS and sensor data transmission from vehicles, containers, or heavy machinery for logistics management.
  • Renewable Energy Monitoring: Collecting performance data from solar inverters, wind turbines, or battery storage systems in remote locations.
  • Building Automation: Integrating legacy HVAC, lighting, and power meters in commercial buildings into modern IoT cloud dashboards.

Frequently Asked Questions

How do I configure the MQTT settings on this 4G gateway?

Connect the gateway to power and your local network via Ethernet. Access its built-in web UI by entering its default IP address in a browser. Navigate to the Cloud/MQTT configuration section. Here, enter your broker's server address, port (typically 1883 for MQTT, 8883 for MQTT over TLS), client ID, username, and password. Define your publish and subscribe topics for data routing. Save the settings and reboot the gateway for the changes to take effect.

What is the procedure for wiring Modbus RTU devices to the RS485 port?

Identify the A (Data+), B (Data-), and GND terminals on the gateway's RS485 screw terminal block. Connect the corresponding A and B lines from your Modbus sensor or PLC to these terminals, ensuring correct polarity for stable communication. Connect the signal ground (GND) if your device requires it. Configure the gateway's web interface with the correct Modbus parameters: baud rate (e.g., 9600, 19200), data bits (8), parity (None, Even, Odd), and stop bits (1). Assign a unique slave ID to each device on the RS485 bus.

What power supply specifications are required for reliable operation?

The gateway requires a stable 12V DC power source. Its input accepts a wide range of 15 to 40VDC, making it compatible with industrial power supplies or regulated battery systems. Ensure your power adapter can provide at least 150mA continuous current. For installations prone to voltage spikes, such as in vehicles or near motors, use a fused power line and consider adding transient voltage suppression. The unit is not designed for AC mains voltage; always use a certified DC power adapter.
