• P1/P2 (RS-232/422/485, TxD/RxD): These LEDs indicate the current serial mode and data transmission/reception activity for each port.

Konnetturi:

• Port USB: Type B connector for connection to the host computer.
• Serial Ports (Port 1, Port 2): DB9 male connectors for RS-232/422/485 serial devices.
• Jack tal-Enerġija: Locking power jack for external power adapter (if required by application or specific model).

5. Setup and Driver Installation

5.1 Installazzjoni tas-sewwieq

Before connecting the UPort 1250 to your computer, install the necessary drivers. Drivers are available for Windows, WinCE, and Linux operating systems. Refer to the included documentation or the Moxa website for the latest driver downloads and installation instructions specific to your operating system.

1. Download the appropriate driver package from the Moxa official websit.
2. Oħroġ is-sewwieq files to a temporary directory.
3. Follow the on-screen instructions provided by the driver installer.
4. Ibda mill-ġdid il-kompjuter tiegħek jekk tintalab.

5.2 Konnessjoni tal-Ħardwer

1. Connect the USB Type B port on the UPort 1250 to an available USB port on your host computer using the provided USB cable. The "USB" LED on the hub should illuminate.
2. If external power is required, connect the power adapter to the locking power jack on the UPort 1250 and then to a power outlet.
3. Connect your serial devices to the DB9 serial ports (Port 1 and Port 2) on the UPort 1250. Ensure correct pin assignments for RS-232, RS-422, or RS-485 as per your device's requirements.
4. After successful driver installation and hardware connection, the operating system should recognize the new COM ports.

5.3 COM Port Utility

The UPort 1250 supports a fixed-base COM Utility. This utility allows you to configure and manage the assigned COM port numbers, which can be useful in environments where specific COM port assignments are required for legacy applications or system consistency. Refer to the Moxa software documentation for detailed instructions on using this utility.

6. Istruzzjonijiet Operattivi

6.1 Serial Communication Modes

The UPort 1250 supports RS-232, RS-422, and RS-485 communication modes. The mode is typically auto-detected or configured via software settings depending on the connected device and driver capabilities. Ensure your serial device is configured to match the UPort's port settings.

• RS-232: Standard serial communication for point-to-point connections.
• RS-422: Differential signaling for longer distances and higher noise immunity, typically point-to-multipoint.
• RS-485 (2-wire/4-wire): Multi-drop communication for connecting multiple devices on a single bus. The UPort 1250 supports both 2-wire and 4-wire configurations.

6.2 Trażmissjoni tad-Data

Once drivers are installed and devices are connected, your application software can access the serial ports as standard COM ports. Configure your application with the correct COM port number, baud rate (up to 921.6 Kbps), data bits, stop bits, and parity settings to match your serial device.

The TxD/RxD LEDs for each port will flash to indicate data transmission (TxD) and reception (RxD) activity, providing visual confirmation of communication.

7. Manutenzjoni

• Tindif: Uża drapp artab u niexef biex tnaddaf il-barra tal-apparat. Tużax prodotti tat-tindif likwidi jew aerosol.
• Ambjent: Operate the UPort 1250 within its specified environmental conditions (temperature, humidity) to ensure optimal performance and longevity.
• Protezzjoni ESD: The device features 15KV ESD protection. However, always handle the device and connected cables with care to minimize static discharge, especially in dry environments.

8 Issolvi l-problemi

• Apparat Mhux Rikonoxxut:
  • Ensure the USB cable is securely connected to both the UPort 1250 and the host computer.
  • Verify that the USB LED on the UPort 1250 is illuminated.
  • Check if the drivers are correctly installed in your operating system's Device Manager (Windows) or equivalent. Reinstall drivers if necessary.
  • Ipprova qabbad ma 'port USB differenti fuq il-kompjuter tiegħek.
• L-ebda Komunikazzjoni ma' Apparat Serjali:
  • Confirm that the serial device is properly connected to the UPort 1250's serial port.
  • Verify that your application software is configured with the correct COM port number, baud rate, data bits, stop bits, and parity settings.
  • Check the TxD/RxD LEDs on the UPort 1250 for activity. If no LEDs flash during communication attempts, there might be an issue with the serial device or its connection.
  • Ensure the correct serial mode (RS-232/422/485) is selected or auto-detected.
• Intermittent Connection/Data Loss:
  • Iċċekkja għal konnessjonijiet tal-kejbil maħlula.
  • Ensure the power supply is stable and correctly connected (if external power is used).
  • Minimize electromagnetic interference by keeping the device away from strong electrical fields.
