Common issues and troubleshooting tips UPort 1130


A flexible USB-to-serial converter, the UPort 1130 is made to reliably connect serial devices to a USB port. Although it is usually dependable, users could occasionally run into problems that need to be troubleshooted.

Driver Installation Issues

  • Verify Compatibility: Make sure that your operating system and the UPort 1130 are compatible. Examine the support materials and product specs.
  • Download the Latest Drivers: Get the most recent operating system drivers by going to the official Moxa website.
  • Manual Installation: Automatic driver installation can occasionally go wrong. Use the Device Manager to manually install the driver by going to the UPort 1130, right-clicking on it, and choosing “Update Driver” or “Install Driver.”
  • Check USB Port: Try using a different USB port to test the UPort 1130. Certain ports might not have enough power or might not be connected properly.
  • Disable Driver Signature Enforcement: To install the driver, you might need to turn off driver signature enforcement on various Windows versions. The Advanced Boot Options menu is where you may accomplish this.

Device Not Recognized

Even after the driver installation process is complete, the computer can still not detect the UPort 1130. This may show up as the device being shown with a yellow exclamation point or not showing up at all in the Device Manager.

  • Try a Different USB Cable: Faulty or low-quality USB cables can cause connectivity problems.
  • Power Supply: Ensure that the USB port or hub provides adequate power. If using a hub, try connecting the UPort 1130 directly to the computer.
  • Update BIOS/Chipset Drivers: Ensure that your computer’s BIOS and chipset drivers are up to date. Outdated drivers can cause USB devices to malfunction.
  • Check for Conflicts: Ensure that no other USB-to-serial adapters are causing conflicts. Disconnect other adapters and see if the UPort 1130 is recognized.

Communication Errors

  • Check Serial Settings: Ensure that the serial settings (baud rate, data bits, parity, stop bits, and flow control) on both the UPort 1130 and the connected serial device match.
  • Replace Cables: Faulty serial cables can cause communication errors. Try replacing the serial cable.
  • Verify COM Port: Ensure that the correct COM port is selected in the software that is communicating with the serial device.
  • Test with Another Device: Test the UPort 1130 with another serial device to determine if the issue is with the adapter or the original serial device.
  • Use a Different Software: Sometimes, the software being used to communicate with the serial device may have bugs. Try using different communication software to rule out software-related issues.

Power Issues

Power issues can lead to the UPort 1130 not functioning correctly, especially if the connected serial device requires additional power.

  • Self-Powered USB Hub: Use a self-powered USB hub to ensure that adequate power is supplied to the UPort 1130.
  • Check Power Requirements: Verify the power requirements of the connected serial device and ensure that it is within the limits that the UPort 1130 can handle.

Firmware Issues

  • Follow Update Instructions: Carefully follow the instructions provided for updating the firmware. Ensure that the device remains connected and powered during the update process.
  • Backup Configuration: Before updating the firmware, back up the current configuration settings to avoid losing important settings.

Environmental Factors

Environmental factors such as extreme temperatures, electromagnetic interference, and physical damage can affect the performance of the UPort 1130.

  • Stable Environment: Ensure that the UPort 1130 is operated in a stable environment within the recommended temperature range.
  • Avoid Interference: Keep the device away from sources of electromagnetic interference, such as large motors, transformers, and wireless devices.
