PAX G10-S 'Unknown Error' Diagnostic Report Following... | terminalfaults.org

Technical Background:

Lightning strikes generate electromagnetic pulses (EMP) and power surges. These events can induce high voltages in nearby electrical circuits, potentially damaging sensitive electronic components within the G10-S. Damage can affect the power supply, communication interfaces (NFC/EMV), or the main processor. Corrupted firmware due to voltage spikes is also a possibility. Signal attenuation across damaged PCB traces can also contribute to the error state.

Symptoms:

PAX G10-S card terminal displays an 'Unknown Error' message. The error occurred after a reported lightning strike in the vicinity of the kiosk location.

Possible Causes:

Damaged power supply unit (PSU) resulting in unstable voltage levels.
Surge damage to the main processor or associated memory.
Corruption of the device firmware due to voltage spikes.
Damage to the EMV chip or NFC antenna, leading to communication failure.
Failure of surge protection circuitry within the G10-S.
Physical damage to internal PCB traces or components.

Solution:

1

Visually inspect the exterior of the G10-S for any signs of physical damage (burn marks, cracks, etc.).
2

Check the power source. Verify the input voltage to the kiosk is within the specified range for the G10-S (typically 12V DC).
3

Disconnect and reconnect the power cable to the G10-S. Ensure the connection is secure.
4

If possible, test the G10-S with a different, known-good power adapter of the same voltage and amperage.
5

Check the communication cables (Ethernet/Serial) for damage. Reseat the connectors.
6

Attempt a factory reset of the G10-S (refer to the PAX G10-S technical manual for the specific key combination). Note: this may require a technician-level privilege.
7

Contact PAX technical support for further diagnostics and potential firmware re-flashing procedures. Provide them with the error message and details of the lightning strike event.

Safety Warning:

Exercise caution when handling electrical equipment. Ensure the power supply is disconnected before inspecting any cables or connections. Do not attempt to open the G10-S casing, as this will void the warranty and trigger anti-tamper mechanisms, rendering the device permanently unusable. Risk of electric shock exists if the device is connected to a damaged power source. Safe Handling procedures apply – unplug the device and ensure a dry surface for inspection.

Prevention:

Install a surge protector on the power line feeding the kiosk.,Ensure proper grounding of the kiosk enclosure to minimize the risk of static discharge and electrical surges.,Regularly inspect power and communication cables for wear and tear. Replace damaged cables immediately.,Consider a lightning rod system for the building housing the kiosk, if applicable and cost-effective.,Implement a scheduled preventative maintenance program to check the functionality of the surge protection devices.

Expert Tip:

A common failure point after electrical surges is the serial communication port. Try connecting to the G10-S via the USB interface (if available) to check the terminal's core functionality, even if the primary interface is non-operational. Sometimes, a simple power cycle (unplugging and re-plugging) can clear transient memory errors caused by voltage fluctuations.

Frequently Asked Questions

•Was the G10-S connected to a surge protector at the time of the lightning strike?

This information is crucial for determining the effectiveness of the surge protection measures in place.

•Are there any other devices connected to the same power circuit as the G10-S that are also experiencing issues?

This helps to determine the scope of the damage and identify potential power-related problems.

•Has the G10-S been exposed to extreme temperatures or humidity?

Environmental factors can exacerbate the effects of electrical surges and contribute to component failure.
