Poynt Terminal GPS Failure Diagnostic Report - Solar Faults | terminalfaults.org

Technical Background:

The Poynt Terminal GPS module relies on satellite signal acquisition for location data. Signal attenuation, hardware malfunction, or software errors can cause failure. GPS modules typically operate on L1 frequency (1575.42 MHz). Insufficient voltage to the GPS module or corrupted firmware can also trigger the error. ESD events can disrupt the sensitive GPS receiver circuitry.

Symptoms:

Poynt Terminal displays "Invalid Location" error, indicating GPS module failure.

Possible Causes:

GPS antenna signal attenuation due to physical obstructions (e.g., metallic shelving, reinforced concrete).
GPS module hardware failure (e.g., receiver chip malfunction).
Firmware corruption affecting GPS module operation.
Intermittent power supply issue to the GPS module (voltage fluctuation).
Electrostatic Discharge (ESD) damage to the GPS module during handling.
Loose or damaged internal GPS antenna connector.

Solution:

1

Relocate the Poynt Terminal to an area with a clear view of the sky, away from potential obstructions.
2

Verify the Poynt Terminal has the latest firmware installed. Check for updates through the device settings.
3

Power cycle the terminal: Unplug the power adapter, wait 30 seconds, and reconnect.
4

Inspect the power cable for damage or strain. Ensure a secure connection to the terminal.
5

If possible, test the terminal in a different location known to have good GPS signal reception.
6

Contact Poynt support for advanced diagnostics or replacement options. Do NOT attempt to open the device.
7

Document all troubleshooting steps taken and the results for future reference.

Safety Warning:

Safe Handling: Always unplug the Poynt Terminal from the power outlet before performing any cleaning or inspection. Avoid using liquids directly on the device. ESD is a risk, particularly in dry environments. Ground yourself before touching the device. Do NOT attempt to open the device as it contains tamper-evident mechanisms that will permanently disable the device.

Prevention:

Ensure the Poynt Terminal is positioned in a location with minimal signal obstruction.,Regularly check for and install firmware updates.,Provide strain relief for all connected cables to prevent damage.,Clean the terminal screen and exterior regularly with a dry, antistatic cloth.,Implement ESD prevention measures, especially during dry winter months (e.g., antistatic mats).

Expert Tip:

Try performing a GPS cold start (if supported by the device, consult the manual, but do NOT attempt any internal modifications). A cold start forces the GPS module to reacquire satellite data from scratch, which can sometimes resolve persistent location errors. Inspect the external antenna connection if accessible without opening the device; ensure it is secure.
