Driver Installation

Upon connecting the UPort 1650-8 to your computer, the operating system may attempt to install drivers automatically. If automatic installation fails or if you require specific driver versions, please refer to the Moxa website for the latest drivers compatible with your Windows, WinCE, or Linux operating system. Follow the on-screen instructions provided by the driver installer.

5. Operating Instructions

Once the hardware is connected and drivers are successfully installed, the UPort 1650-8 will create virtual COM ports on your host computer. These COM ports can be accessed and configured using standard serial communication software or applications. Refer to your operating system's device manager to identify the assigned COM port numbers.

• Data Transmission: The 'Tx' and 'Rx' LEDs for each serial port will flash to indicate active data transmission and reception, respectively. The 'Active' LED will illuminate when the device is properly connected via USB and powered on.
• Baud Rate Configuration: Configure the baud rate, data bits, parity, and stop bits within your serial communication software to match the settings of your connected serial devices. The UPort 1650-8 supports baud rates up to 921.6 kbps.

6. Maintenance

• Cleaning: Disconnect power before cleaning. Use a soft, dry cloth to wipe the exterior of the device. Avoid using liquid cleaners or solvents.
• Environmental Conditions: Ensure the device is operated within its specified temperature and humidity ranges. Avoid exposing the unit to excessive dust, moisture, or direct sunlight.

• No Data Transmission:
  • Check the 'Tx' and 'Rx' LEDs for activity. If they are not flashing, verify the serial cable connections to your devices.
  • Confirm that the COM port settings (baud rate, data bits, parity, stop bits) in your software match those of your serial device.
  • Ensure the correct COM port is selected in your application.
  • Verify the wiring for RS-422/485 connections, especially for termination and biasing.
• Intermittent Connection:
  • Check for loose cable connections (USB, power, serial).
  • Ensure the power supply is stable.
