How to install Advantech 1-port RS-232/422/485 Serial Device Server

• Unbox and locate a suitable deployment spot: Choose a dry, accessible area near the serial device and within reach of your network switch or router to simplify cabling.
• Connect the serial device: Attach the RS-232, RS-422, or RS-485 cable from your PLC, meter, or sensor to the 1-port serial interface on the device server. Ensure correct wiring for the chosen serial mode (point-to-point or multi-drop for RS-485).
• Link to the network: Plug an Ethernet cable into the device server’s Ethernet port and connect it to your switch, router, or edge gateway. Confirm link activity with the indicator LEDs if available.
• Power up and assign an IP address: Power on the device server. Use a DHCP-enabled network to obtain an IP automatically or configure a static IP via the web-based management interface for consistent accessibility.
• Configure serial and network settings: Access the web UI using the device’s IP address. Set serial parameters (baud rate, data bits, parity, stop bits) and choose the transport mode (for example, TCP server, TCP client, or UDP) that matches your application. Save changes and reboot if prompted, then verify data flow from the serial device to the target application or dashboard.
