Frequently Asked Questions

How do I configure the MQTT connection on the WIN-GW-4G+RS485 gateway?

Access the gateway's web interface via its local IP address. Navigate to the Cloud Settings or MQTT configuration page. Enter your broker's server address (IP or URL), port (typically 1883 for unencrypted, 8883 for TLS), client ID, username, and password. Configure the publish/subscribe topics for your data points. Save the settings and restart the gateway to establish the connection. Verify the status on the dashboard.

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

Identify the A (positive) and B (negative) data lines on your Modbus RTU sensor or PLC. Connect these to the corresponding A+ and B- terminals on the gateway's RS485 screw terminal block. Ensure proper termination (a 120-ohm resistor) is enabled at the end of the bus if required for your network length. Configure the gateway's Modbus settings (baud rate: 9600, 19200, etc.; parity; stop bits) in the web UI to match your slave device parameters. Assign unique slave IDs to each device on the bus.

What power supply specifications are required for reliable operation?

The gateway requires a stable 24VDC power supply, typically connected to the provided screw terminal block. Ensure the power source can deliver sufficient current, generally around 0.5A to 1A, to account for peak cellular transmission loads. For permanent installations, use a DIN-rail mounted 24VDC switching power supply rated for industrial environments. Avoid using undersized or unregulated power adapters, as voltage fluctuations can cause instability or damage to the cellular modem.
