6. Operating Instructions
6.1 Verifying COM Port Assignment
After driver installation and hardware connection, verify the assigned COM port numbers:
- Windows: Open Device Manager (right-click "This PC" or "My Computer" > Manage > Device Manager). Expand "Ports (COM & LPT)" to see the Moxa UPort serial ports and their assigned COM numbers.
- Linux: Use commands like
dmesg | grep ttyUSBor check/dev/ttyUSB*to identify the serial devices.
6.2 Communicating with Serial Devices
Use your preferred serial communication software (e.g., PuTTY, Tera Term, HyperTerminal, custom applications) to interact with your connected serial devices. Configure the software with the correct COM port number, baud rate, data bits, parity, and stop bits as required by your serial device.
- Baud Rate: Up to 921.6 kbps.
- Data Bits: 5, 6, 7, or 8.
- Parity: None, Odd, Even, Mark, Space.
- Stop Bits: 1, 1.5, or 2.
- Flow Control: None, RTS/CTS, XON/XOFF.
Observe the Tx/Rx LEDs on the front panel; they will flash when data is being transmitted or received on the corresponding port.
7. Maintenance
The Moxa UPort 1650-16 is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:
- Cleaning: Keep the device clean and free from dust. Use a soft, dry cloth for cleaning. Avoid liquid cleaners or solvents.

8. Troubleshooting
If you encounter issues with your UPort 1650-16, consider the following troubleshooting steps:
- Device Not Detected:
- Ensure the USB cable is securely connected to both the UPort and the computer.
- Verify that the power adapter is connected and the device is powered on (Active LED illuminated).
- Check Device Manager (Windows) or
dmesg(Linux) to see if the device is recognized. Reinstall drivers if necessary. - Try a different USB port on your computer or a different USB cable.
- No Communication with Serial Device:
- Confirm the correct COM port is selected in your serial communication software.
- Verify that the baud rate, data bits, parity, and stop bits settings match those of your serial device.
- Check the serial cable connection between the UPort and your device. Ensure it's a straight-through or null-modem cable as required.
- Observe the Tx/Rx LEDs. If they are not flashing during communication attempts, there might be an issue with the serial device or its configuration.
- Intermittent Connection:
- Ensure proper grounding of the UPort 1650-16.
- Check for electromagnetic interference (EMI) from other equipment.
- Verify the integrity of the USB and serial cables.
If problems persist, consult the Moxa support website or contact technical support.
