Waveshare Industrial 4G RS485 to LTE Cat4 DIN Rail Gateway (EU)

Configuration is performed via AT commands sent through its serial port, a dedicated Windows host computer software, or a built-in web interface accessible over the network. You will need to set parameters like the target server's IP address/domain, port number, serial baud rate (2400-230400), and working mode (e.g., TCP Client). A SIM card with an active data plan for the supported region must be installed prior to power-up. The initial setup typically involves connecting via USB-to-serial adapter or directly through the RS485 terminals after applying 9-36V DC power.

This EU variant supports LTE-FDD and GSM bands primarily used across Europe, the Middle East, Africa (EMEA), Korea, Thailand, India, and Southeast Asia. Key bands include GSM B3 (1800 MHz) and B8 (900 MHz), with specific LTE bands dependent on the regional frequency allocation. It is critical to verify carrier compatibility in your country. The modem is LTE Category 4, offering peak download speeds of 150 Mbps and upload speeds of 50 Mbps, with automatic fallback to 3G and 2G networks where LTE coverage is unavailable.

The RS485 interface uses a screw terminal block for connecting the A, B, and GND lines from your field device. The gateway incorporates robust hardware protection, including Level 4 ESD (Electrostatic Discharge) protection, Level 3 surge protection, and Level 3 EFT (Electrical Fast Transient) protection on the serial lines. This safeguards the internal circuitry from voltage spikes, inductive load switching noise, and electrostatic discharge commonly encountered in industrial environments, ensuring stable long-term operation when connected to PLCs, motor drives, or long cable runs.
