5. Installation

5.1 Connexions physiques

1. Connecter un périphérique série : Connect your RS-232, RS-422, or RS-485 serial device to the serial port on the NPORT DE-211. Ensure the correct cable type is used for your specific serial interface.
2. Se connecter au réseau Ethernet : Use a standard Ethernet cable to connect the NPORT DE-211's Ethernet port to your network switch or router.
3. Connecter l'alimentation : Connect a compatible DC power adapter (not included) to the power input jack. Ensure the power supply meets the device's voltage et les exigences actuelles.

5.2 Configuration des commutateurs DIP

The NPORT DE-211 features DIP switches on its rear panel. These switches are used to configure the serial interface type (RS-232, RS-422, or RS-485) and other operational parameters. Refer to the detailed configuration guide available on the Moxa support website for specific DIP switch settings corresponding to your desired serial mode and application.

6. Modes de fonctionnement

The NPORT DE-211 supports various operating modes to suit different network communication requirements:

• Mode serveur TCP : The NPORT DE-211 listens for incoming TCP connections from host computers.
• Mode client TCP : The NPORT DE-211 actively initiates a TCP connection to a specified host IP address and port.
• Mode UDP : Data is transmitted using the User Datagram Protocol, suitable for applications where speed is prioritized over guaranteed delivery.
• Ethernet Modem Mode: Allows serial devices to communicate over Ethernet as if they were connected via a modem.
• Mode de connexion par paire : Establishes a direct connection between two NPORT devices over an Ethernet network, creating a virtual serial cable.

Detailed configuration for each mode is performed via the device's web console or utility software.

7. Entretien

To ensure optimal performance and longevity of your NPORT DE-211, follow these general maintenance guidelines:

• Environnement: Operate the device within its specified temperature and humidity ranges. Avoid exposure to direct sunlight, excessive dust, or moisture.
• Nettoyage: Utilisez un chiffon doux et sec pour nettoyer l'extérieur de l'appareil. N'utilisez pas de nettoyants liquides ni en aérosol.
• Mises à jour du micrologiciel : Vérifiez périodiquement le moxa webSite de mise à jour du micrologiciel pour garantir que votre appareil bénéficie des dernières fonctionnalités et améliorations de sécurité.

8. Dépannage

If you encounter issues with your NPORT DE-211, consider the following troubleshooting steps:

• Vérification de l'alimentation : Verify that the power adapter is correctly connected and supplying power to the device. Check the power indicator LED.
• Connectivité réseau : Ensure the Ethernet cable is securely connected and that the network link/activity LEDs are functioning. Confirm network settings (IP address, subnet mask, gateway).
• Connexion série : Double-check the serial cable connection to your device and verify that the serial port settings (baud rate, data bits, parity, stop bits) match those of the connected serial device.
• Paramètres du commutateur DIP : Confirm that the DIP switches are correctly configured for the desired serial interface type (RS-232/422/485).
• Software Drivers: If using Real COM/TTY drivers, ensure they are correctly installed and configured on your operating system.
• Réinitialiser l'appareil: If issues persist, try performing a soft reset via the device's web interface or a hard reset using the physical reset button (refer to the full manual for reset procedures).
