8. Troubleshooting
This section provides solutions to common issues. For more complex problems, consult the full user manual or contact MOXA technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not powering on | Incorrect power connection, faulty power supply, incorrect voltage. | Verify power cable connection and polarity. Check power supply voltage (9-30 VDC). Test with a known good power supply. |
| No wireless connection | Incorrect wireless settings (SSID, security key), out of range, antenna issues, access point problem. | Check wireless configuration in the device's web interface. Ensure antennas are securely attached. Move the device closer to the access point. Verify the access point is operational. |
| Ethernet devices not connecting | Faulty Ethernet cable, incorrect IP settings, device port issue. | Test with a different Ethernet cable. Verify IP address and subnet mask settings. Check LED indicators for link status. |
| Serial communication failure | Incorrect serial port settings (baud rate, parity), incorrect wiring, faulty serial cable. | Verify serial port configuration (baud rate, data bits, parity, stop bits, flow control) matches the connected device. Check serial cable wiring (RS-232/422/485). |
