4. Guia de configuració

Follow these steps to set up your USR-W610 converter:

1. Attach WiFi Antenna: Screw the provided WiFi antenna onto the antenna connector on the device.
   

   Figure 4: USR-W610 with the WiFi antenna connected.

2. Connectar l'alimentació: Connect a DC 5-36V power adapter to the DC power input port. The Power indicator should light up.
3. Connect Serial Device:
   • For RS232: Connect your RS232 device to the DB9 male port.
   • For RS485: Connect your RS485 device to the screw terminal (A and B).
4. Network Connection (Choose one):
   • Ethernet: Connect an Ethernet cable from the converter's RJ45 port to your network router or switch.
   • WiFi: The device can operate in AP or STA mode. For initial configuration, it may broadcast its own WiFi network (AP mode) or you can connect it to an existing WiFi network (STA mode) via the web interfície.
5. Configuració inicial:

   Accedir al dispositiu web interface by connecting your computer to the same network (either via Ethernet or by connecting to the device's default WiFi AP). Refer to the device's default IP address (usually found in the quick start guide or on the device label) to access the web configuration page. The default language might be Chinese; locate the language selection option to switch to English.

5. Modes de funcionament

The USR-W610 supports several operational modes to suit different application requirements:

5.1. Transparent Transmission Mode

In this mode, data transmitted or received through the serial port is directly forwarded to the WiFi/Ethernet interface without any parsing or modification. This simplifies integration with existing serial protocols.

5.2. HTTP Client Mode

When configured as an HTTP Client, serial data can be submitted to a specified HTTP server using GET, POST, or PUT request methods. This is useful for web-based data logging or control applications.

5.3. AT Command Mode

This mode allows users to query and set device parameters using standard AT commands, either through the serial port or over the network. This provides a flexible way to configure the module programmatically.

5.4. Modbus Polling Mode

The device supports Modbus TCP and Modbus RTU mutual conversion, acting as a Modbus gateway. This enables Modbus RTU devices to communicate over TCP/IP networks.

5.5. Socket Distribution Protocol (SDP)

SDP allows for adding specific headers to serial data, enabling the device to send data to different sockets based on these headers. Conversely, data received from different sockets can have distinct headers added before being sent to the serial port.

6. Manteniment

To ensure optimal performance and longevity of your USR-W610 converter, consider the following maintenance guidelines:

• Condicions ambientals: Operate the device within its specified temperature and humidity ranges. Avoid exposure to extreme temperatures, direct sunlight, or high moisture environments.
• Neteja: Keep the device clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid cleaners or solvents.
• Actualitzacions de firmware: Reviseu periòdicament el fabricant website for firmware updates. Updating the firmware can improve performance, add new features, and address potential issues.
• Regular Restart Function: Utilize the built-in timing and timeout restart functions to maintain system stability, especially in long-term, continuous operation scenarios. Configure these settings via the web interfície.
• Font d'alimentació: Ensure a stable power supply within the DC 5-36V range. Unstable power can affect device operation.
• Integritat de la connexió: Periodically check all cable connections (power, Ethernet, serial) to ensure they are secure and free from damage.

7. Solució De Problemes

This section addresses common issues you might encounter with the USR-W610 converter.

7.1. No Power Indicator Light

• Comproveu la connexió d'alimentació: Assegureu-vos que l'adaptador de corrent estigui connectat correctament al dispositiu i a una presa de corrent que funcioni.
• Verifica l'adaptador de corrent: Confirm the power adapter provides DC 5-36V and is functioning correctly.

7.2. No es pot accedir Web Interfície

• Connexió de xarxa: Ensure your computer is connected to the same network as the USR-W610 (either via Ethernet or its WiFi AP).
• Adreça IP: Verify you are using the correct IP address for the device. If unsure, try connecting directly via Ethernet and check your network's DHCP client list or use a network scanner tool.
• Tallafoc: Temporarily disable your computer's firewall to rule out blocking access.
• Restableix el dispositiu: If all else fails, perform a hardware reload using the reload button. This will revert settings to factory defaults, including the IP address.

7.3. Problemes de connexió Wi-Fi

• Antena: Ensure the WiFi antenna is securely attached.
• Intensitat del senyal: Check the WiFi signal strength in the device's location. Move the device closer to the access point if necessary.
• Configuració: Double-check WiFi SSID, password, and security type settings in the web interfície.
• AP/STA Mode: Confirm the device is configured in the correct WiFi mode (AP, STA, or AP+STA) for your network setup.

7.4. Serial Data Transmission Problems

• Cablejat: Verify correct wiring for RS232 (Tx, Rx, GND) or RS485 (A, B).
• Serial Parameters: Ensure the baud rate, data bits, parity, and stop bits configured on the USR-W610 match those of your serial device.
• Mode de funcionament: Confirm the device is in the appropriate operating mode (e.g., Transparent Transmission Mode for direct data passthrough).
• TXD/RXD Indicators: Observe the TXD/RXD LEDs for activity. If they are not flashing, there might be an issue with the serial connection or the connected device.
