Lantronix UDS1100 Device Server with PoE Instruction Manual

1. Introduction

This manual provides essential instructions for the installation, operation, and maintenance of the Lantronix UDS1100 Device Server with Power Over Ethernet (PoE). The UDS1100 is designed to connect serial devices to an IP network, enabling remote access and management of equipment with serial interfaces.

2. Product Overview

The Lantronix UDS1100 is a robust one-port device server that facilitates the integration of serial devices into modern Ethernet networks. It supports multiple serial standards including RS232, RS422, and RS485, making it versatile for various industrial and commercial applications. The integrated Power Over Ethernet (PoE) capability simplifies installation by allowing power and data to be transmitted over a single Ethernet cable.

Key features include:

• One serial port supporting RS232, RS422, and RS485.
• Ethernet and Fast Ethernet data link protocols.
• Data transfer rates up to 100 Megabits Per Second.
• Power Over Ethernet (PoE) for flexible power options.
• UL864 compliance for specific applications.

3. Setup

Follow these steps to set up your Lantronix UDS1100 Device Server:

1. Unpack the Device: Carefully remove the UDS1100 from its packaging and inspect for any physical damage.
2. Connect the Serial Device: Connect your serial device (e.g., PLC, sensor, barcode scanner) to the serial port on the UDS1100 using an appropriate serial cable (RS232, RS422, or RS485). Ensure the cable is securely fastened.
3. Connect to Network and Power:
   • Using PoE: Connect a standard Ethernet cable from the UDS1100's Ethernet port to a PoE-enabled network switch or a PoE injector. This will provide both data connectivity and power to the device.
   • Using External Power (if PoE is not available): If not using PoE, connect an appropriate external power supply (not included with all models) to the power input jack on the UDS1100. Then, connect a standard Ethernet cable from the UDS1100's Ethernet port to your network switch or router.
4. Initial Configuration: Once powered on and connected to the network, the UDS1100 will acquire an IP address (typically via DHCP). Use the Lantronix Device Installer utility (available from the manufacturer's website) or a web browser to discover the device on your network and configure its network settings (e.g., static IP address, subnet mask, gateway) and serial port parameters (e.g., baud rate, data bits, parity, stop bits, flow control) to match your serial device.

4. Operating Instructions

After successful setup and configuration, the UDS1100 enables your serial device to communicate over the network. Common operating modes include:

• Virtual COM Port: Install the Lantronix Com Port Redirector software on your host PC. This software creates a virtual COM port on your PC that maps directly to the serial port on the UDS1100. Applications designed to communicate with local serial ports can then access the remote serial device as if it were directly connected.
• TCP/UDP Socket Connection: Applications can establish a direct TCP or UDP socket connection to the UDS1100's IP address and configured port. This allows raw serial data to be sent and received over the network. This mode is often used for custom applications or when a virtual COM port is not suitable.
• Web Interface: The UDS1100 features a built-in web server, accessible via its IP address in a standard web browser. This interface allows for monitoring device status, viewing logs, and making configuration changes remotely.

Ensure that the serial parameters configured on the UDS1100 (baud rate, data bits, parity, stop bits, flow control) precisely match those of the connected serial device for proper communication.

5. Maintenance

To ensure optimal performance and longevity of your Lantronix UDS1100 Device Server, consider the following maintenance guidelines:

• Environmental Conditions: Operate the device within its specified temperature and humidity ranges. Avoid exposing it to extreme temperatures, direct sunlight, or excessive moisture.
• Cleaning: Keep the device clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid or aerosol cleaners directly on the device.
• Ventilation: Ensure that the device has adequate ventilation to prevent overheating. Do not block any ventilation openings.
• Firmware Updates: Periodically check the Lantronix website for firmware updates. Applying the latest firmware can improve performance, add new features, and address security vulnerabilities. Follow the manufacturer's instructions carefully when performing firmware updates.
• Cable Integrity: Regularly inspect all connected cables (serial and Ethernet) for signs of wear or damage. Replace damaged cables immediately to prevent connectivity issues.

6. Troubleshooting

If you encounter issues with your UDS1100, refer to the following troubleshooting tips:

• Device Not Powering On:
  • Verify that the Ethernet cable is securely connected to a PoE-enabled switch/injector or that the external power supply is correctly connected and providing power.
  • Check the power source for functionality.
• No Network Connectivity:
  • Ensure the Ethernet cable is properly connected to both the UDS1100 and the network switch/router.
  • Check the network status LEDs on the UDS1100 and the connected network device.
  • Verify network settings (IP address, subnet mask, gateway) are correct and do not conflict with other devices on the network.
  • Ping the UDS1100's IP address from a computer on the same network.
• Serial Communication Errors:
  • Confirm that the serial port settings (baud rate, data bits, parity, stop bits, flow control) on the UDS1100 match the settings of the connected serial device.
  • Ensure the correct serial cable type (straight-through or null-modem) is used and that it is securely connected.
  • Test the serial device directly with a computer to rule out issues with the device itself.
  • Check for any error messages in the UDS1100's web interface or logs.
• Cannot Access Web Interface:
  • Ensure you are using the correct IP address for the UDS1100.
  • Verify that your computer is on the same network segment as the UDS1100 or that routing is correctly configured.
  • Temporarily disable any firewall software on your computer to see if it is blocking access.
