Dejavoo Z11: Diagnosing Network Timeout Errors - Solar... | terminalfaults.org

Technical Background:

Timeout errors typically arise from interruptions or delays in network communication. Potential issues include:
1. **Network Latency:** High latency or packet loss on the network.
2. **Signal Attenuation:** Weak signal strength, particularly in wireless networks.
3. **TCP/IP Configuration Errors:** Incorrect IP address, subnet mask, gateway, or DNS settings.
4. **Power Supply Fluctuations:** Voltage drops can interrupt network operations.
5. **Electrostatic Discharge (ESD):** Static electricity can corrupt data packets or temporarily disable network components.

Symptoms:

The Dejavoo Z11 terminal displays a 'Timeout Error' during network communication. Transactions are not processed, and the terminal may become unresponsive.

Possible Causes:

**Network Connectivity Issues:** Intermittent or complete loss of network connection (Wi-Fi or Ethernet)
**Faulty Ethernet Cable:** Damaged or improperly connected Ethernet cable (if applicable)
**Incorrect Network Configuration:** Incorrect IP address, DNS settings, or other network parameters
**Power Supply Problems:** Insufficient or unstable power supply to the terminal
**Software Glitch:** Temporary software error or conflict within the terminal's operating system
**Router/Firewall Configuration:** Router or firewall blocking communication on necessary ports

Solution:

1

*Verify Network Connection:** Ensure the terminal is connected to the network via Ethernet or Wi-Fi. Check network cables are securely plugged in.
2

*Restart the Terminal:** Perform a soft reset by unplugging the power adapter, waiting 10 seconds, and plugging it back in.
3

*Check Network Settings:** Verify the terminal's IP address, subnet mask, gateway, and DNS settings. Ensure they are correct for the network.
4

*Test Network Connectivity:** Use a network diagnostic tool (if available on the terminal) or ping a known-good IP address (e.g., 8.8.8.8) to verify connectivity.
5

*Inspect Cables:** Visually inspect the Ethernet cable for damage. Try a different known-good cable.
6

*Check Router/Firewall:** Confirm that the router and firewall are not blocking the terminal's network traffic. Consult with your IT department.
7

*Monitor Power Supply:** Ensure the terminal is connected to a stable power source. If possible, test with a different power outlet.

Safety Warning:

1. **Safe Handling:** Always unplug the terminal from the power outlet before inspecting or cleaning.
2. **ESD Precautions:** Ground yourself before touching the terminal to prevent electrostatic discharge. Avoid working on the terminal in carpeted areas during dry weather.
3. **Do NOT Open:** Do not attempt to open the terminal's casing. This will void the warranty and may damage the device's tamper-evident security features.

Prevention:

1. **Regular Cleaning:** Clean the terminal's exterior regularly with a dry, antistatic cloth.
2. **Cable Management:** Ensure network and power cables are properly routed and secured to prevent strain.
3. **Surge Protection:** Use a surge protector to protect the terminal from power surges.
4. **Environmental Control:** Minimize static electricity by maintaining adequate humidity levels, especially during dry months.

Expert Tip:

If the terminal is using DHCP, try setting a static IP address outside of the DHCP range to prevent IP address conflicts. Note the MAC address for router/firewall exception rules.
